Britain’s economy delivered a resilient 0.3% growth in the second quarter of 2025, maintaining its position as the Group of Seven’s fastest-growing economy in the first half of the year, according to data released Tuesday by the Office for National Statistics (ONS). However, beneath this positive headline lurks a concerning development: the current account deficit surged to £28.9 billion ($38.8 billion), significantly exceeding forecasts and raising questions about the sustainability of Britain’s economic recovery.
The Q2 GDP figure, unrevised from the ONS’ initial estimate and precisely in line with a Reuters poll of economists, represents a deceleration from the robust 0.7% growth recorded in the first quarter. While the headline number appears solid, deeper analysis reveals an economy grappling with structural challenges, external vulnerabilities, and the lingering effects of one-off factors that artificially boosted earlier performance.

G7 Leadership With Caveats
Britain’s claim to G7 economic leadership in H1 2025 deserves context. The country’s year-on-year GDP growth of 1.4% in Q2—revised upward from an initial 1.2% estimate—outpaced the Eurozone’s anemic performance, particularly Germany’s 0.3% contraction. However, this relative strength reflects as much on European weakness as British dynamism.
“The economy was weak across April and May, with some activity having been brought forward to February and March ahead of Stamp Duty and tariff changes, but then recovered strongly in June,” explained Liz McKeown, Director of Economic Statistics at the ONS. This admission of timing distortions underscores how temporary factors inflated first-quarter growth at the expense of subsequent quarters.
The Bank of England projects overall 2025 growth of just 1.25%—a modest expansion that hardly suggests economic vibrancy. For perspective, the International Monetary Fund slightly raised its UK growth forecast for 2025 from 1.1% to 1.2%, while the OECD nudged its projection from 1.3% to 1.4%. These incremental upgrades reflect mechanical adjustments rather than fundamental reassessments of Britain’s economic trajectory.
Per capita GDP growth tells a sobering story. At 0.9% year-on-year in Q2, real output per person barely outpaced population growth, highlighting limited improvements in individual living standards despite headline GDP expansion.
The One-Off Factor Problem
Much of Britain’s H1 outperformance stems from transitory dynamics that will not recur. The rush of exports before U.S. import tariffs took effect artificially boosted trade figures in early 2025. Businesses accelerated capital expenditure ahead of anticipated cost increases, pulling forward demand that would otherwise have materialized later.
The EY ITEM Club, which upgraded its 2025 GDP forecast from 0.8% to 1%, explicitly acknowledged this pattern: “This flurry of business spending at the start of the year has led the EY ITEM Club to upgrade its expectations for business investment growth in 2025 to 1.3%, up from 0.3%.”
However, the same analysis warned that “this level of growth is unlikely to be sustained into the second half of 2025 or into 2026, with US tariffs expected to impact some UK exports and prompt some businesses to pause spending decisions amid heightened levels of uncertainty.” Business investment growth is forecast to flatline at 0.0% in 2026 before recovering to 1.8% in 2027.
The Q2 sectoral breakdown reveals the fragility of growth drivers. Services output, which contributed 0.4%, remains the economy’s primary engine. Computer programming, consultancy, scientific R&D, engineering, and car sales—particularly electric vehicles—performed strongly. Construction added 1.2%, recovering from earlier volatility. Production, conversely, fell 0.3%, highlighting manufacturing’s continued struggles.
The Current Account Crisis
While GDP growth garnered headlines, the more troubling development lies in Britain’s external position. The Q2 current account deficit of £28.9 billion—equivalent to 3.8% of GDP—substantially exceeded the consensus forecast of £24.9 billion and deteriorated sharply from Q1’s 2.8% of GDP.
Britain has run a persistent current account deficit since 1984, positioning it as a net borrower from the rest of the world. The deficit indicates that overall expenditure in the UK exceeds national income, requiring Britain to attract net financial inflows through either disposing of overseas assets or accruing liabilities with foreign investors.
The Q2 deterioration stemmed primarily from a £7.7 billion widening in the primary income deficit—which tracks earnings on investments and reflects returns UK investors earn abroad versus what foreign investors earn in Britain. UK receipts (credits) fell £2.1 billion to £94.9 billion, as earnings on all investment types declined. Simultaneously, UK payments (debits) to foreign investors surged £5.6 billion to £111.7 billion, driven by £4.7 billion in increased direct investment payments and £1.7 billion in higher portfolio investment payments.
This represents a fundamental challenge. The UK must continuously attract foreign capital to finance consumption and investment exceeding domestic income. In Q2, the financial account recorded a net inflow of £33.0 billion—capital that UK residents borrowed from abroad or assets they sold to foreign buyers. Any disruption to these capital flows could trigger sterling depreciation and force painful economic adjustments.
The trade component of the current account also deteriorated, though less dramatically. The goods deficit widened £5.8 billion to £56.6 billion (7.5% of GDP) as exports plunged £6.5 billion while imports declined only £0.7 billion. The partial offset came from an expanded services surplus, which grew £5.5 billion to £53.8 billion (7.1% of GDP), underscoring Britain’s comparative advantage in services trade.
Specific commodity movements reveal vulnerabilities. Exports of aircraft engines, motor cars, and road vehicles contracted sharply. The aircraft sector’s -25.6% quarterly decline in exports particularly concerns policymakers given aerospace’s strategic importance. Chemical exports also weakened significantly.
Sectoral Performance: Services Carry the Load
The services sector, comprising approximately 80% of the British economy, remains the primary growth engine. Q2 services output grew 0.4%, driven by information and communication (+3.2% over three months), administrative and support services (+2.3%), and professional, scientific and technical activities.
Within services, computer programming, consultancy and related activities surged 3.0% in June alone. This reflects Britain’s continued strength in technology services and digital economy segments. Financial services, insurance, and professional services—traditional UK strengths—posted solid if unspectacular gains.
However, services growth masks weakness in goods-producing sectors. Manufacturing output, a component of the broader production category that fell 0.3% in Q2, continues struggling with competitiveness challenges. Energy-intensive industries face high costs, while regulatory burdens and skills shortages constrain expansion.
The construction sector’s 1.2% Q2 growth represents recovery from volatility rather than sustained momentum. Construction remains sensitive to interest rate dynamics and planning restrictions that constrain housebuilding—a perennial UK economic challenge.

The Interest Rate Conundrum
The Bank of England faces an unenviable balancing act. Having cut rates from 4.25% to 4% in August, the Monetary Policy Committee (MPC) must weigh sticky inflation—which rose to 3.6% in June from 3.4% in May—against cooling labor markets and lackluster growth.
The August rate cut came after heated debate, with the MPC initially split 4-4 between holding and cutting rates, plus one member favoring a 50-basis-point reduction. This division reflects the “finely balanced situation” Governor Andrew Bailey described, where traditional policy trade-offs offer no clear resolution.
Inflation persistence complicates matters. At 3.6%, the consumer price index substantially exceeds the BoE’s 2% target. Services inflation—more reflective of domestic wage and price pressures—remains elevated. Yet unemployment has crept upward as hiring slows, creating downward pressure on wage growth that should eventually restrain inflation.
The MPC’s August statement acknowledged that “underlying UK GDP growth has remained subdued, consistent with a continued, gradual loosening in the labour market” and that “a margin of slack is judged to have emerged in the economy.” This language suggests the BoE sees economic weakness justifying lower rates despite above-target inflation.
Further rate cuts depend on inflation trajectory and labor market dynamics. Markets currently anticipate gradual easing through 2026, though trajectories vary widely among forecasters. The EY ITEM Club expects inflation averaging 3.4% in 2025 despite easing monetary policy, with pay growth slowing to around 3.5% by year-end and 3% by H2 2026 as rising unemployment restrains wage demands.
Fiscal Policy Constraints
Chancellor of the Exchequer Rachel Reeves operates under self-imposed fiscal rules limiting government borrowing. While characterizing the Q2 GDP data as positive, Reeves acknowledged “there is more to do to deliver an economy that works for working people.”
However, her fiscal constraints limit policy flexibility. Public sector net debt reached 95.8% of GDP in fiscal year 2024/25 (90% excluding Bank of England holdings). Government expenditure totaled approximately £1.28 trillion (44.7% of GDP), financed by £1.13 trillion in revenue and £151 billion in borrowing.
Debt interest costs have surged as higher interest rates increase servicing expenses on the accumulated debt stock. This constrains capacity for fiscal stimulus even as economic growth disappoints. Labour’s pre-election pledges to avoid raising Income Tax, National Insurance (for employees), or VAT further limit revenue options, though the government has raised employer National Insurance contributions and trimmed benefits like Winter Fuel Payments.
Critics like Unite general secretary Sharon Graham argue Reeves’ fiscal rules are “shackling the economy.” However, breaking self-imposed constraints risks market backlash and higher borrowing costs—the fate that befell Liz Truss’s brief premiership in autumn 2022 when ill-considered tax cuts sparked gilt market turmoil.
Structural Challenges and Productivity Puzzle
Britain’s modest growth partly reflects deep-seated structural issues. Productivity growth—output per hour worked—has stagnated since the 2008 financial crisis, a phenomenon economists term the “productivity puzzle.” Without productivity improvements, sustainable living standard increases prove elusive.
Multiple factors contribute to weak productivity: inadequate business investment, infrastructure deficits, skills mismatches, and regulatory complexity. The UK invests less in plant, equipment, and technology than competitors, handicapping efficiency gains. Transport infrastructure bottlenecks constrain economic geography. Skills training frequently misaligns with employer needs, creating shortages in critical areas while leaving workers underemployed elsewhere.
Brexit’s long-term productivity impact remains contested. Reduced EU trade integration and labor mobility constraints impose costs, though Brexit proponents argue regulatory autonomy enables offsetting reforms. To date, evidence suggests modest net economic drag, though disentangling Brexit effects from pandemic impacts and other shocks proves methodologically challenging.
Regional disparities compound national challenges. London and Southeast England significantly outperform other regions in productivity and income. “Leveling up” initiatives aim to address geographic inequality, but progress remains halting.
External Trade Vulnerabilities
The widening current account deficit highlights Britain’s external vulnerabilities. As an economy historically dependent on financial services exports and running persistent goods trade deficits, the UK proves sensitive to global financial conditions and trade disruptions.
The goods deficit’s expansion to £56.6 billion in Q2 reflects long-standing manufacturing decline and import dependence. Britain imports far more consumer goods, food, and manufactured products than it exports. While services surpluses partially offset goods deficits, the UK remains structurally exposed to terms-of-trade shocks and requires continuous capital inflows.
Primary income deterioration compounds trade challenges. Historically, Britain earned substantial investment income from overseas assets, helping finance trade deficits. Recent quarters show this income cushion eroding, forcing greater reliance on borrowed capital or asset sales. The Q2 primary income deficit of £16.8 billion (2.2% of GDP) represents a significant drain on national income.
Geopolitical uncertainties exacerbate external risks. U.S. trade policy volatility, European economic weakness, and potential protectionist escalation threaten UK export markets. While the UK-US trade agreement provides relief versus worst-case tariff scenarios, Britain’s access to key markets remains reduced from pre-disruption levels.
The Path Forward: Constraints and Choices
British policymakers confront difficult choices. Monetary easing risks re-igniting inflation before it sustainably returns to target. Fiscal stimulus clashes with debt sustainability concerns and self-imposed constraints. Structural reforms—addressing productivity, regional inequality, and trade vulnerabilities—require years to yield results.
Near-term outlook appears subdued. The EY ITEM Club forecasts GDP growth remaining around 1% through 2026 before modest acceleration toward 1.5% in 2027. Business investment likely stagnates through 2026 before recovering. Consumer spending growth remains constrained by high interest rates, elevated inflation, and weakening labor markets.
Political economy considerations complicate reform. Labour’s October 2024 election victory ended 14 years of Conservative governance, but the government operates with thin margins and must balance competing constituencies. Trade unions demand worker-friendly policies potentially increasing business costs. Business groups seek tax relief and regulatory simplification. Regional interests demand investment. International investors require macroeconomic stability and policy predictability.
The current account deficit trajectory particularly concerns economists. Without improvement, Britain risks balance-of-payments crises if foreign capital inflows prove insufficient or investor confidence wavers. Sterling depreciation could force adjustment, but this transmits inflation through higher import costs—the very outcome monetary policy seeks to contain.
Optimists note Britain’s economic resilience and adaptability. Services sector strength, particularly in technology and professional services, provides competitive advantages. London’s position as a global financial center endures despite Brexit and regulatory changes. Universities produce world-class research. Creative industries thrive.
Pessimists counter that without addressing productivity stagnation, infrastructure deficits, and external imbalances, Britain faces prolonged low-growth equilibrium. Aging demographics constrain labor supply growth. Climate transition requires massive investment. Global economic fragmentation threatens open economies dependent on services exports and capital inflows.
Conclusion: Managing the Paradox
Britain’s Q2 economic performance encapsulates a fundamental paradox: superficially strong growth masking deeper vulnerabilities. Leading the G7 in H1 2025 growth sounds impressive until examining the composition, sustainability, and external financing of that expansion.
The widening current account deficit to 3.8% of GDP represents the story’s headline beyond GDP growth figures. This external drain exceeding forecasts signals that Britain’s economic model—consuming and investing more than it produces, financed by foreign capital and asset sales—faces sustainability questions.
Policymakers must navigate between competing imperatives: supporting growth without reigniting inflation, addressing structural weaknesses within fiscal constraints, and managing external vulnerabilities without triggering market disruptions. The BoE’s rate-cutting cycle, begun in August despite above-target inflation, reflects these difficult trade-offs.
For households and businesses, the outlook suggests continued challenging conditions. Real wage growth remains constrained. Employment prospects weaken as firms exercise hiring caution. Living standards improve only gradually if at all.
Britain’s economic paradox—strong relative performance concealing absolute challenges—will define the policy debate through 2026 and beyond. The Q2 data provides both reassurance and warning: growth continues, but its foundations appear less solid than headline numbers suggest. Addressing the external deficit, productivity stagnation, and structural weaknesses requires sustained effort and difficult choices that political leaders have yet to fully embrace.
As one analyst summarized the situation: “The glass is half full today, but we’re drinking from it faster than we’re refilling it.”
