Britain’s polycrisis—fiscal fragility, decades of austerity policy, a cost-of-living crisis, stagnating living standards, and political instability—stems not from exogenous shocks but from a failed growth model of financialisation, regressive taxation, and chronic underinvestment. Dr Kalim Siddiqui analyses macroeconomic indicators, fiscal constraints imposed by bond markets, and a governance crisis of ministerial churn and impossible trilemma. Escape requires fundamental renegotiation of the state’s productive investment role, progressive taxation, not mere technical adjustment.

I. Introduction

The British growth model is in terminal crisis. This article argues that the United Kingdom’s (UK) contemporary economic malaise cannot be understood as a mere cyclical downturn, but rather as the product of deep structural contradictions between a finance-dependent accumulation regime, severe fiscal constraints inherited from a decade of austerity, and a paralysing crisis of governance that has rendered long-term strategic intervention impossible.

Britain is currently navigating a polycrisis that extends far beyond the parameters of a standard economic recession, encompassing a deep-seated structural malaise that is at once fiscal, social, and political (The Guardian, 2026). This crisis is not merely the product of exogenous shocks, but rather the culmination of a protracted growth model built upon financialisation and regressive taxation—a model now laid bare by geopolitical volatility, persistently anaemic productivity, and a profound erosion of state capacity.

Against this backdrop, there is a compelling case for increasing taxes on the super-rich and large corporations, entities that have disproportionately benefited from four decades of neoliberalism and globalisation. The current landscape is defined by a precarious triad of vulnerabilities: acute sensitivity in sovereign bond markets, two decades of stagnating median living standards, and a descent into party-political instability that has rendered long-term economic planning virtually untenable (Tooze, 2022).

This is not a conventional business cycle downturn, but what some scholars have termed a ‘polycrisis’, wherein multiple interdependent crises—economic, fiscal, social, and political—reinforce one another in a self-perpetuating downward spiral (Tooze, 2022).

Contemporary Britain exhibits all the hallmarks of this syndrome. Sovereign bond yields remain sensitive to the faintest whisper of fiscal indiscipline, a legacy of the 2022 ‘mini-budget’ episode that brutally exposed the market’s tolerance limits. Real wages have stagnated for nearly two decades, eroding the living standards of majority of the population. Public infrastructure—from schools to hospitals to transport networks—has deteriorated to levels that provoke international embarrassment. Meanwhile, Britain has witnessed unprecedented executive fragility, with five prime ministers in eight years and a cabinet turnover rate that renders long-term policy planning virtually impossible (The Guardian, 2026).

Britain still projects an image of wealth, but beneath the surface the economy has largely stagnated for almost two decades. Rising house prices have created the illusion of growing prosperity, yet for most homeowners the gains are largely paper wealth: selling simply means buying into an equally inflated market. Today, the average home in England costs 7.7 times the median annual salary, rising to 10.5 times in London and as much as 25 times in some areas. By comparison, in the 1980s a home was generally considered affordable at around three to four times average earnings.

This article advances a central issue: Britain’s contemporary crisis is fundamentally a crisis of its growth model. Drawing on the comparative political economy literature (Blyth, 2013), the British growth is accumulation strategies that generate economic expansion within a given national context, but hardly reaches the three-quarter of the population. The growth is siphoned off by the small elites. The British growth model has been historically reliant on financial services, asset-price inflation, and regressive taxation—a configuration that proved increasingly unstable following the 2008 financial crisis and has now reached its terminal limits (Siddiqui, 2024a).

Successive governments have increasingly relied toward the financial sector, fostering a heavily indebted economy built on speculative wealth rather than productive enterprise. This model has exacerbated asset inequality and entrenched privatised monopolies—particularly in utilities such as water—that extract rent rather than stimulate innovation or long-term investment. I contend that this trajectory reflects a deep-seated adherence to neoliberal orthodoxy, which has simultaneously opposed deficit-financed public investment and resisted progressive taxation on large corporations and high-net-worth individuals. The result has been a progressive paralysis of the state’s capacity to fund critical infrastructure or effectively alleviate the cost-of-living crisis.

Beyond these macroeconomic failings, Britain confronts a profound regional imbalance, with wealth and opportunity overwhelmingly concentrated in London and the South East, while peripheral regions—especially the North—have suffered extensive deindustrialisation and economic marginalisation. These systemic ailments, further compounded by an ageing population, are not cyclical fluctuations but symptomatic of a deeper, possibly terminal, decline in the British growth model. At its core, this model—defined by privatisation, austerity, financialisation, and globalisation—has reached its limits, and the current crisis demands a fundamental reorientation of economic strategy (Siddiqui, 2019).

The study proceeds with the examining the macroeconomic data, with particular attention to the energy-inflation nexus and its consequences for monetary policy and labour markets. And then discusses focuses to the fiscal dimension, analysing how a decade of austerity has eroded the state’s productive capacity while simultaneously rendering it hostage to bond market sentiment. And finally, analysis the governance crisis, exploring how political fragmentation and institutional decay have undermined the state’s capacity to formulate and implement strategic economic policy.

II. Falling Growth Rates

Sustained growth is essential for the economy to expand, for employment to rise, and, hopefully, for household incomes to improve. In the UK, the Office for National Statistics (ONS) releases monthly GDP figures, but these are often volatile. As a result, economists consider the quarterly data—which covers three-month periods—to be a more reliable indicator of the economy’s underlying health.

According to the latest ONS release, the UK economy contracted by 0.1% in April, as businesses began to feel the ripple effects of the conflict in Iran.

More strikingly, the broader trajectory reveals a clear downward trend. After growing by 1.3% across the whole of 2025—up from 1.0% in 2024—the UK economy expanded by 0.6% in the first quarter of the year. However, that pace is already showing signs of fading, with growth expected to remain sluggish in the months ahead. This slowdown is not new. The final quarter of 2023 already recorded negative growth, and the momentum has failed to recover sustainably since then.

By March 2026, UK GDP growth for the first quarter was estimated at just over 0.5%—the weakest March reading in two years (see Figure 1a). Compared to the 0.6% seen in the previous quarter, this marks a noticeable deceleration, reinforcing concerns that the economy is losing steam. GDP per head tells a starker story. Between 2022 and 2026, the per head decline is deeper — none more so than in 2022–2023, when the Russian-Ukraine war took hold (Figure 1b).

According to the Bank of England (BoE, 2025) growth forecasts, UK GDP growth is expected to remain almost stagnant, continuing the weak performance observed since 2022. Although the economy recovered in 2021 following the sharp contraction caused by the COVID-19 pandemic (Figure 1c), growth has remained subdued. Moreover, there is little indication that growth rates will return to the stronger levels experienced prior to 2008 financial crisis.

Figure 1d: UK GDP Per Capita, 1993-2026.

There was broad-based growth in services and construction. Professional, scientific, and technical activities, along with information and communication, performed well — signalling rising investment in AI and the tech sector.

However, some concerns are emerging, not least from rising fuel and chemical costs, which have weighed on other sectors. Machinery and equipment contracted, and administrative and support services also declined.

Comparing GDP growth across advanced economies against pre-pandemic levels (2020 = baseline) reveals that the UK has significantly underperformed relative to other major developed nations, as shown in Figure 2 (Siddiqui, 2025a).

Moreover, financial assets and the real economy—comprising primarily industry and construction—are fundamentally distinct. This distinction also helps explain why trust in the capitalist system occasionally breaks down. The relationship between the real economy and the financial sphere is essentially dialectical in nature. While financial growth has undoubtedly supported the development of the real economy in various ways, it can also prove highly disruptive. Fictitious financial assets, in particular, can evaporate in a very short period. The contradiction between the fictitious and the real intensifies as the ratio of financial value to real economic value increases.

In reality, the expansion of the supply of tangible goods depends on the development of productive forces, the availability of means of production, the size and skill of the labour force, and other material conditions. The supply of fictitious assets, however, is not constrained by such limitations. Speculation itself is not a new phenomenon. What is new is the growing power of large capital, which can now influence price movements, thereby create asset price bubbles and enabling profits to be extracted from them (Tooze, 2022).

Figure 2: GDP % Change of Advanced Capitalist Countries Compared to Pre-Pandemic Level with 2020.

It’s the inevitable result of 40 years of neoliberal economic policy that has trebled UK private debt, collapsed the velocity of money to just 1.2 times per year, and redistributed wealth from the working class to asset owners. Britain’s economy hasn’t just slowed but it’s been hollowed out, and no prime minister was able to fix it without a fundamental shift from elite driven economic policy.

The UK government focus on reducing public debt and deficits, but seems to be counterproductive. He argues that attempts to simultaneously deleverage the public and private sectors choke the money supply and push the economy down. Private debt (like mortgages) is the real threat to financial stability. Figure 3 presents UK’s private debt trends from 1980 to 2020. The data reveals a pronounced and sustained increase in both corporate borrowing and household indebtedness over the forty-year period.

Figure 3: UK’s Private Debts, 1980-2020 (% of GDP).

The British economy’s vulnerability to external shocks has been brutally exposed by the geopolitical reverberations of the US/Israeli-Iranian conflict. Disruptions to global oil and natural gas supply chains have fed directly into domestic inflation, with the Consumer Prices Index (CPI) persisting at 2.8% — significantly above the Bank of England’s 2% target (BoE, 2025). This is not a transitory phenomenon; the structural realignment of global energy markets following the Russian invasion of Ukraine has permanently altered the UK’s terms of trade, rendering it a net importer of inflation (IMF, 2024).

The tightening monetary stance has coincided with a marked deterioration in real economic activity. Early-year growth momentum, buoyed by a post-pandemic rebound, has now dissipated, signalling contractionary trajectories in both manufacturing and services — the twin engines of the British economy (BoE, 2025). Manufacturing, in particular, has been afflicted by declining export competitiveness, a weak investment climate, and persistent supply-chain disruptions.

The surge in youth unemployment, which has reached its highest level since the aftermath of the 2008 global financial crisis, is not merely a cyclical phenomenon. Rather, it reflects a structural mismatch between the skills demanded by a low-investment, service-oriented economy and those possessed by younger cohorts entering the labour market (OECD, 2024). The long-term scarring effects — including lower lifetime earnings, reduced productivity, and increased reliance on welfare — are likely to exacerbate the fiscal pressures discussed below.

III. Bond Market Discipline and Fiscal Fragility

The UK’s infrastructure deficit cannot be easily addressed. Fiscal space is severely constrained by sovereign bond markets. The yield on 10-year gilts remains at multi-decade highs — driven not only by global monetary conditions but also by a UK-specific risk premium. This premium stems directly from the 2022 ‘mini-budget’ debacle, which shattered market confidence, sent sterling plunging, and triggered a classic ‘bond vigilante’ revolt (Turner, 2023). Figure 4 shows UK bond yields over the past thirty years.

In this climate, any perceived fiscal indiscipline — whether excessive borrowing or unfunded tax cuts — risks a sudden stop in capital flows and a spike in borrowing costs (Siddiqui, 2017).  The British state is effectively held hostage by market sentiment, vulnerable to a self-fulfilling debt crisis (Turner, 2023).

This forces governments to prioritise deficit reduction over productive investment, regardless of economic conditions. The result is a fiscal straitjacket that precludes the expansionary policies needed to escape the UK’s low-growth equilibrium.

Figure 4: UK’s Bond Yield, 1998-2026.

IV. Austerity’s Legacy and the Deterioration of Public Infrastructure

Perhaps the most visible manifestation of Britain’s structural decay is the catastrophic state of its public infrastructure. Over a decade of fiscal consolidation — pursued under the rubric of austerity — has systematically diverted capital budgets towards recurrent day-to-day spending. The consequences are now starkly visible: school buildings at risk of collapse, NHS waiting lists at record highs, and local authorities declaring effective bankruptcy.

This infrastructure deficit is not merely a matter of public service quality; it has direct implications for the economy’s supply-side capacity. Poor transport links, inadequate digital infrastructure, and a degraded educational estate all depress private sector productivity and deter inward investment. The UK now ranks significantly below its OECD peers on measures of public capital stock per capital. (OECD, 2024; IMF, 2024).

These supply-side constraints are largely self-inflicted, rooted in the political economy of austerity (Siddiqui, 2024a). Successive governments have redirected capital expenditure towards meeting immediate spending pressures, undermining the country’s productive capacity and locking the UK into a low-growth trajectory (Siddiqui, 2013).

From a political economy perspective, these trends reveal the interplay between structural economic weaknesses and institutional constraints. Yet growth alone cannot raise living standards unless it supports real wage increases, enables fairer taxation of wealth, and expands fiscal space without overburdening workers. Britain’s persistent productivity slowdown has stifled GDP growth, undermining both private-sector dynamism and public-sector capacity. The confluence of weak growth, fiscal strain, and political fragmentation casts doubt on the sustainability of the UK’s economic model and the state’s ability to resolve deep-rooted challenges.

Rather than a series of isolated shocks, these developments represent a systemic crisis of Britain’s political economy. The mutually reinforcing dynamics of low productivity, constrained public finances, geopolitical volatility, financial market pressures, and eroding political trust have created a vicious cycle of stagnation and institutional fragility. Recognising this interdependence is crucial both for diagnosing the UK’s current malaise and for assessing the strategic options open to future governments.

V. The Governance Crisis: Political Instability and Institutional Decay

Britain’s governance crisis is acute. Five PMs in eight years, 70% cabinet turnover, and a collapsing two-party system have paralysed long-term strategy. Governments are trapped in permanent electioneering, choosing tax cuts over investment and avoiding reforms like ending austerity or fixing vocational education.

This executive fragility is both cause and consequence of a deeper political realignment. The collapse of the traditional two-party duopoly — evidenced by poor local election results and the rise of third parties — has intensified intra-party factionalism and rendered parliamentary majorities increasingly precarious. Governments now govern in a state of permanent electioneering, prioritising short-term political survival over the painful structural reforms that the economy demands (Siddiqui, 2024a).

The crisis has now claimed another victim. Keir Starmer has resigned as Prime Minister, becoming the sixth person to leave office in a turbulent decade of UK politics. Elected in 2024 with a landslide Labour victory, Starmer had pledged to bring stability, grow the economy, and end years of Conservative Party chaos. Barely two years later, he was forced to step down after his popularity plummeted and his government struggled to deliver on its promise to “rebuild Britain.” This rapid turnover is unprecedented in British political history. By contrast, the preceding four decades saw just six prime ministers — the same number as the past ten years alone (see Figure 5).

Figure 5: Succession of British Prime Ministers since 2010.

VI. Neoliberalism

Neoliberalism seeks to transfer control of economic factors from the public to the private sector. (Siddiqui, 2025b). For decades, financial assets have grown faster than the real economy — and the gap has widened significantly in recent years. In the United States (US), for example, the ratio of stock market capitalisation to GDP rose from 52% in 1990 to 151% in 2025 (World Bank, 2026). This growing divergence between finance and the real economy is a major driver of wealth and income inequality across most countries (Mattei, 2022).

The privatisation and commodification of key spheres — particularly education — has also undermined the pursuit of academic life as a critical activity. Yet neoliberalism is rarely what it appears to be (Figure 6). It is not simply about competition or free markets; rather, it entrenches the power of financial giants, military-industrial players, and tech monopolies, while leaving ordinary citizens exposed to market volatility. Its legacy is a dead end: skyrocketing inequality and wealth concentration rivalling the 1950s.

Figure 6: The Core Components of Neoliberal Economic Policy

Table 1 presents a comparison of per capita GDP growth across advanced capitalist economies, contrasting the pre-neoliberal era with the neoliberal period. In all cases, growth performance in the neoliberal period is weaker, with the differential consistently negative.

Table 1: Per-Capita Economic Growth Rates in the Advanced Capitalist Economies.

 VII. Rising Inequality in the UK

Since 1960, UK disposable household income inequality has evolved through four distinct phases. The figure presents two measures: the 90:10 ratio — comparing the 90th and 10th percentiles — and the income share of the top 1%. A higher 90:10 ratio signals greater inequality between top and bottom earners.

However, experiences varied across groups. Pensioner poverty plummeted from 41% in 1989 to 18% in 2019. Child poverty saw a modest decline from the early 2000s, partially reversing after 2010. Meanwhile, relative poverty among working-age adults without children actually increased from the 1990s until the financial crisis.

UK inequality since 1961 (Figure 7a): flat in the 1960s–70s, surged in the 1980s, stabilised 1990–2008 (top 1% kept pulling away), little change since. The 90:10 ratio and top 1% share both rose sharply in the 1980s. Figure 7b shows children are the worst affected by rising poverty.

Relative poverty (below 60% of median income) followed a similar path. Pensioner poverty fell from 41% to 18% (1989–2019). Child poverty declined modestly then partially reversed after 2010. Working-age adults without children saw poverty rise from the 1990s to 2008.

Figure 7a: Inequality among UK Households, 1960–2020.

Figure 7b: Relative Poverty Rate by Demographic Groups, 1960-2020.

These are the real resources of a country: the buildings, the land, the hospitals, the schools. This is real wealth. And yet, year after year, an increasing share of this wealth is being concentrated in the hands of a tiny group of people whom we currently lack the capacity to tax—even if we wished to do so.

Governments once owned substantial wealth and industries. But over time, government net worth has fallen from over 100 per cent of GDP to negative 100 per cent of GDP. The wealth that used to be owned by the state, by workers, and by the middle class has not disappeared—it has simply been transferred into the hands of the rich. At current rates of taxation, the UK is moving rapidly towards extreme wealth inequality and widespread homelessness.

The young will be among the hardest hit. Consider this: if house prices double over the next five years, someone who is now 18 years old will be 23 and will recognise that they have zero chance of getting onto the housing ladder—of ever reaching that level playing field. Such people, despairing of economic opportunity, become easy prey for narratives that blame immigrants and foreigners, and they are increasingly drawn to the far right. This seems to be the present trajectory.

Extreme right-wing movements offer seemingly simple economic solutions: kick out the foreigners. The blame for economic crises is shifted onto immigrants and outsiders, who are not, in fact, the ones making decisions or governing the country. The laws and policies are made by those in power; yet when those policies fail, the failures are conveniently projected onto foreigners and immigrants.

The UK is not alone among developed countries in experiencing rising income inequality over the past six decades. However, inequality in the UK has grown more sharply than in most OECD countries (Siddiqui, 2025c). Today, UK income inequality is high by international standards—as shown in Figure 8, which presents the Gini coefficient for OECD nations. Beneath this summary measure, a more telling picture emerges: it is largely the degree of inequality between high-income and middle-income households that sets the UK apart from many of its peers (OECD, 2024).

Figure 8: Gini-Coefficient of Income Inequality Across OECD Countries, 2020.

VIII. Taxing the Super-Rich: A Minimum Tax Proposal

There is an urgent need to impose progressive taxation on the super-rich, and I advocate here for the introduction of a wealth tax in Britain. If any meaningful change is to be achieved and the current status quo reversed, it is imperative to tax the rich more heavily and to tax wealth itself. The wealthy are not only economically powerful; their concentration of resources also affords them disproportionate influence over politics and business. If the new Labour government—led by Andy Burnham—genuinely wishes to deliver real change, it must adopt progressive taxation as a central tool to reverse the rising tide of income and wealth inequality (Financial Times, 2026).

A wealth tax operates on a straightforward principle: it is levied on the total value of an individual’s assets, rather than on their income. For example, a person worth £1 million would pay 2% annually, amounting to £20,000 per year. Someone worth £20 million would pay 2% on the portion above £10 million, equating to £200,000 annually. Crucially, such a tax would only be paid by the very wealthy.

The underlying rationale is to halt the accelerating concentration of wealth in fewer and fewer hands. As things stand, workers grow poorer, the middle class is squeezed, public finances deteriorate, and vast sums of wealth accumulate in the bank accounts of the richest individuals—who currently pay little or no tax on it. It is worth emphasising that these individuals presently enjoy extremely low effective tax rates, precisely because their wealth does not derive primarily from income. We have constructed a tax system that is highly effective at taxing working people—at rates of 50% or even 60%—but it scarcely touches the super-rich at all.

What explains the aggressive rise in the living standards of the super-rich over recent decades? Over the past five years, the average British family has struggled to pay energy bills, feed their children, and cope with a relentless cost-of-living crisis. On the streets of the UK, conditions are palpably worse than they were five years ago—and worse than ten years ago, worse than twenty, and so on, in a downward trajectory that shows no sign of abating.

Consider this: six years ago, the world’s richest man was worth just over £100 billion. Last month, the world’s richest man accumulated a trillion dollars in the span of just six years. What we are witnessing is billionaires growing their wealth at annual rates of 30, 40, or even 50 per cent. This staggering concentration of wealth makes it abundantly clear that urgent policy change is needed to address the inequality at the very top—to reverse the trend that has placed nearly all the gains of economic growth into the hands of the top 1 per cent.

The injustice is compounded by the structure of our tax system. Workers pay higher rates on their income than wealthy individuals pay on their capital gains. Yet the problem is even more insidious: capital gains tax is only triggered upon sale. A wealthy person, for example, might generate £50 million a year in passive income—roughly £1 million per week—and still pay a far lower effective tax rate than an ordinary employee.

A wealthy person, in essence, is someone who owns capital. They own your mortgage. They own government debt. They own the houses, the buildings, the skyscrapers. If they are not taxed fairly and their wealth continues to accumulate unchecked, the rest of society will grow progressively poorer. The welfare state will be dismantled by attrition. The NHS and the education system will be systematically reduced. The long-term consequence will be rapid political and economic destabilisation—not just of Britain, but of any country that allows this trajectory to continue.

The notion that billionaires should pay less than ordinary workers is indefensible. The proposal for a minimum tax on the super-rich has achieved broad consensus—by design. It originated from the study conducted for the G20 during Brazil’s presidency in 2024, with the aim of placing new ideas for international cooperation on the agenda.

In 2021, 130 countries agreed to establish a minimum corporate tax rate of 15%—a flawed but significant step forward, marking the first time nations had reached such a common agreement. The underlying logic is powerful: it curbs tax avoidance by ensuring that a multinational company’s tax bill cannot fall below 15% of its profits. The super-rich have benefited enormously from globalisation, yet many pay little or no tax. A minimum tax on wealth is the logical next step.

Political will, however, remains fragile. Andy Burnham retreated from this issue as soon as the right-wing of the Labour Party attacked him. A man who had previously advocated for Britain’s return to such proposals immediately backed down when put on the spot in a constituency with a strong Reform bias. This retreat has effectively handed an opportunity to boost support for Nigel Farage and his right-wing politics (The Financial Time, 2026).

The Conservative Party’s proposed economic strategy centres on three pillars: increased military expenditure, corporate tax cuts, and substantial subsidies for large corporations and high-net-worth individuals—all justified under the guise of stimulating investment and fostering growth. This approach is complemented by continued welfare reductions and the perpetuation of austerity measures. However, increasing defence spending effectively revives a form of military Keynesianism (Siddiqui, 2025d), which not only escalates geopolitical tensions but also prioritizes armament production over social welfare. These measures offer, at best, short-term economic relief. In reality, such a policy framework would accelerate the redistribution of capital away from the working class and toward the already affluent, exacerbating economic inequality without ensuring sustainable prosperity (Siddiqui, 2024a).

Capital, in its search for profits, tends to cluster in particular states and regions (Siddiqui, 2026). The US, EU and China dominate in terms of percentage of world’s GDP and also these regions have geographic concentration of markets (Table 2). China stands out as the major breakout centre of capital accumulation. Together, the US, China, and the EU produce nearly half of global GDP and account for just over half of total global investment. A few other populous economies—India, Indonesia, Brazil, Russia, and Mexico—make the top ten, with Turkey in the top twenty. These represent a substantial mass of output and investment, though none competes with the big three on a per-capita basis. Other relatively large advanced economies—Canada, Britain, Japan, and Saudi Arabia (historically an oil giant, but now diversified into other industries)—also feature prominently.

IX. Critique of Neoliberalism

Over recent decades, neoliberalism has lost much of its political legitimacy. In the UK, policies such as privatisation, fiscal restraint, high interest rates, capital account liberalisation, and the curtailment of trade union power have failed to deliver sustained long-term growth or economic stability.

Yet neoliberalism remains not only the dominant economic policy framework but also the prevailing modality of social and economic reproduction in most countries. First adopted by President Reagan in the US and Prime Minister Margaret Thatcher in the UK four decades ago, it continues to be deeply entrenched in institutional and political life.

In neoclassical theory, capitalist economies are assumed to gravitate spontaneously towards full employment and efficient resource allocation—provided that market imperfections, such as misguided government interventions, trade union activity, or industrial distortions, do not obstruct the adjustment process. These factors are treated as deviations from an otherwise self-correcting system.

John Maynard Keynes fundamentally challenged this view. For Keynes, aggregate output and employment are primarily constrained by aggregate demand. When demand is insufficient—whether owing to pessimistic profit expectations or inadequate state intervention—firms respond by cutting production and laying off workers, thereby triggering recessions from which the economy may not spontaneously recover. This marked a sharp theoretical break with neoclassical orthodoxy.

Nevertheless, Keynesians have struggled to explain why their preferred policies, despite their effectiveness during the postwar boom from the 1950s to the 1970s, eventually interacted with accumulation processes in ways that rendered Keynesianism obsolete and cleared the path for the resurgence of neoliberalism.

Since the early 2000s, this period can be read as a transition from a first-generation form of privatised Keynesianism (roughly 1987–2007) to a second-generation variant emerging from 2020 onward, with a protracted “zombie” interlude in between. Contrary to its own self-presentation, the neoliberalism that took shape in the 1980s was not a wholly anti-Keynesian system. During the early post-war decades, effective demand in the core capitalist economies was sustained not by public redistribution or stable wage growth, but rather by the inflation of financial and property asset prices, household debt-fuelled consumption, and central banks’ implicit guarantees for speculative activities.

While Keynesian fiscal stimulus proved effective in the short run—and governments’ pandemic-era responses indeed vindicated Keynesianism as a tool against economic collapse—stimulus alone leaves the question of economic composition untouched. This is precisely what initiatives such as the Next Generation EU plan and the Inflation Reduction Act largely address. Yet where the demand for full employment is not accompanied by a demand to control the composition of production, Kalecki’s 1943 warning remains fully applicable: capital can accept full employment for as long as it suits its interests, but will resist it as soon as it threatens workplace discipline or capital’s control over the direction of investment.

Ha-Joon Chang (2013), a prominent critique of neoliberalism, argues that the UK’s economic crises stem from a long-term erosion of productive capacity, an over-reliance on financial services, and self-defeating austerity programmes. He contends that these policies have exacerbated inequality and trapped the country in a cycle of low growth and social decay. Austerity, in his view, serves primarily to undermine the welfare state rather than to rectify the fiscal deficit. Chang also points out that, despite massive currency devaluations since 2008, the UK has continued to run persistent trade deficits—a clear indication that the country has lost the capacity to engage in high-productivity activities and to respond effectively to global export incentives.

Ha-Joon Chang (2013) attributes the UK’s economic crisis not to short-term anomalies (Siddiqui, 2024a), but to a decades-long adherence to neoliberal policies, financial deregulation, and a severe erosion of the country’s productive capacity. He argues that the UK’s sustained reliance on the financial sector, combined with austerity measures, has systematically undermined its ability to generate genuine wealth (Blyth, 2013). 

Others, such as Adam Tooze (2022), diagnose the UK economy as fundamentally “broken,” suffering from the most severe growth and productivity slowdown of any advanced nation since the 2008 financial crisis. Tooze attributes this stagnation to chronic underinvestment, the structural effects of Brexit, and overly conservative policymaking that yields to bond market panic rather than pursuing investment-led growth. His key arguments centre on two interconnected issues: first, the productivity crisis—the core problem in the UK is not decoupled wage growth but the fact that productivity growth has completely stalled, with one of the lowest investment rates as a share of GDP among rich economies; and second, the cost of Brexit, which Tooze estimates has structurally reduced national income over the long term.

Brexit remains one of the UK’s most divisive decisions. Before the 2016 Brexit referendum, business investment was growing at around 6% a year—one of the strongest rates in the G7. After the vote, investment growth stalled as firms delayed or cancelled projects amid uncertainty over access to EU markets. The most comprehensive 2025 study concluded that UK GDP is now around 6–8% lower than it would have been without Brexit, highlighting the gap between the promises made and the economic outcome (The Guardian, 2026; Siddiqui, 2024a).

Underpinning these diagnoses is a broader critique of neoclassical economic models, which Tooze believes mislead governments and systematically fail to prevent financial crises. Traditional models treat banks merely as intermediaries—consistent with the loanable funds theory—while ignoring the reality that banks create money “out of thin air” when they issue loans. This conceptual blind spot is particularly damaging in the context of high private debt. In the UK, the current private debt-to-GDP ratio stands at approximately 450 per cent, of which 250 per cent is attributable to financial sector debt alone (Siddiqui, 2023).

Under austerity, cutting state spending during economic downturns depresses growth, degrades public services, and ultimately worsens the very conditions it purports to remedy—driving down living standards in the process. For Chang, the post-1970s neoliberal model of free markets, deregulation, and state retrenchment has been a clear failure. Far from delivering widespread prosperity, this approach has produced higher inequality, stagnant wages, and an economy increasingly vulnerable to financial crises and instability. The over-reliance on finance, in particular, has rendered the economy fragile and susceptible to speculative bubbles and systemic shocks (Saad-Filho, 2017).

To reverse this trajectory, Chang (2013) advocates for a return to a more mixed economy. He strongly supports the implementation of state-led industrial policy, increased public investment in infrastructure and technology, and rigorous regulation of the financial sector—so that it serves the real economy rather than functioning as a vehicle for wealth extraction.

A Marxist examination of the material basis of neoliberalism illuminates several limitations of Keynesianism, two of which are particularly significant (Siddiqui, 2023). First, Keynesians often contend that macroeconomic instability and recurrent financial and balance of payments crises demonstrate neoliberalism’s fundamental flaws. This is correct in the same abstract sense that economic crises reveal capitalism as a flawed mode of production. Yet just as crises offer opportunities to restore balance in capitalist accumulation, they also play a constructive—even constitutive—role under neoliberalism (Saad-Filho, 2017).

A parallel dynamic can be observed with austerity. Following the initial post-First World War boom, restrictive economic policies were implemented in Britain from 1920–21. Austerity was framed as a recurrent ruling-class strategy to suppress working-class militancy and restore both the imperial image and the pound’s status as a global currency (Blyth, 2013). 

What were the effects of austerity in Britain? The reductions in social spending, as Mattei (2022) highlights, were undoubtedly severe. While the initial spending cuts of 1919–22 focused wholly on military expenditure, the Geddes cuts differed in that they fell heavily on civil spending as well—striking hard at an expansionary programme of post-war reconstruction. That programme had been championed by a coalition of Liberals, Conservatives, and a few Labour Party members campaigning together in the so-called “coupon” election of 1918 (Mattei, 2022).

The post-war macroeconomic strategy did achieve certain social-democratic aims: the nationalisation of basic industries and a major extension of welfare state entitlements. However, the physical infrastructure of that welfare—new hospitals and schools—showed little expansion. In effect, only an “austerity welfare state” was constructed (Blyth, 2013). 

Keynesianism was, above all, “an economic theory of the national economy.” In the middle decades of the twentieth century, with trade and capital controls, extensive state control over monetary policy, and a large government budget, such management was both plausible and effective. As one observer put it, “The economic introversion of the 1930s and 1940s created the material basis for such a policy in Britain.”

X. Conclusion: The Limits of the British Growth Model

Ultimately, the British crisis exposes the terminal limits of a growth model predicated on asset-price inflation and service-sector expansion, rather than on high-value-added manufacturing and R&D investment. As the government struggles to reconcile the demands of a restive electorate, the UK finds itself trapped in a low-growth, high-debt equilibrium. Breaking this cycle requires not merely technical fiscal adjustments, but a fundamental renegotiation of the social contract and a wholesale reimagining of the state’s role in productive investment.

The current situation is no conventional business-cycle downturn. Rather, it reflects the interaction of structural economic weaknesses, geopolitical shocks, fiscal constraints, and declining state capacity. Weak productivity growth, persistent regional inequalities, rising income and wealth inequalities, deteriorating public infrastructure, and rising political instability have exposed the fragility of Britain’s post-financial crisis growth model. These developments point to a broader crisis of political economy in which economic performance, fiscal governance, and political legitimacy have become increasingly intertwined (Siddiqui, 2025b).

Recent geopolitical developments have intensified these vulnerabilities. Disruptions to global energy markets following conflict in the Middle East have renewed inflationary pressures, complicating the Bank of England’s monetary policy. Elevated inflation has constrained the scope for interest-rate reductions, while high borrowing costs continue to suppress household consumption, business investment, and mortgage affordability. Although growth showed modest resilience earlier in the year, both manufacturing and service sectors have since weakened, signalling a fragile recovery. Labour market conditions have deteriorated, with vacancies falling to their lowest level in years and youth unemployment rising—raising concerns about long-term scarring and declining productivity (Siddiqui, 2020).

This article has argued that Britain’s contemporary crisis is fundamentally a crisis of its growth model. The model that emerged from the post-1979 neoliberal settlement—reliant on financial services, asset-price inflation, and a regressive tax structure—has reached its terminal limits. Its contradictions are starkly visible: a fiscal state captured by bond market discipline, a real economy starved of productive investment, and a political system paralysed by the conflicting demands of service restoration, defence spending, and electoral survival.

Breaking this low-growth, high-debt equilibrium demands far more than technical adjustments. It requires a strategic industrial policy to rebalance the economy toward high-value-added manufacturing and green technologies; a reformed fiscal framework that clearly distinguishes between current expenditure and capital investment; and a governance overhaul capable of insulating long-term strategy from short-term electoral cycles. Crucially, this transformation must rest on environmentally sustainable industrialisation, rising wages, public investments in infrastructure, and progressive taxation on large corporations and the super-rich—both to curb rising inequalities and to generate the public funds needed for a robust welfare state. At its core, this implies a decisive shift in the distribution of capital.

Whether the British political system is capable of such a transformation remains an open question—and the historical record of the past decade offers little grounds for optimism. But the alternative—continued, managed decline within the straitjacket of a broken economic model—is a future that neither the British economy nor its polity can long sustain.
