UK economy shrank in April as tax rises and US tariffs kicked in

The UK economy unexpectedly contracted by 0.3% in April, driven by increased business taxes, higher household bills, and a significant drop in exports to the US, prompting Chancellor Rachel Reeves to avoid ruling out future tax increases. Economists warn that failure to boost growth will necessitate further tax hikes to balance spending commitments, particularly impacting sectors like services and manufacturing, with the latter affected by new tariffs. While Reeves prioritizes long-term growth projects, immediate spending pressures and investor skepticism regarding government spending plans suggest increased concerns about further tax rises as the autumn Budget approaches.

Analysis

The UK economy experienced an unexpected 0.3% contraction in April, its most significant decline in 18 months, primarily driven by increased business taxes, notably a rise in employers' National Insurance contributions from 13.8% to 15% alongside a reduced payment threshold, higher household bills, and a substantial £2.7 billion decrease in UK exports, including a record £2 billion fall in goods to the US exacerbated by new 25% tariffs on UK vehicles. Chancellor Rachel Reeves acknowledged these "clearly disappointing" figures and has not ruled out further tax increases in the autumn Budget, a sentiment echoed by economists from the Institute for Fiscal Studies and the Resolution Foundation who anticipate more tax hikes if growth fails to materialize sufficiently to cover spending commitments on NHS and defence, which are being prioritized over other squeezed departmental budgets. While the more stable three-month growth figure to April registered 0.7%, the monthly data reveals acute weakness in the services sector, including legal and property firms impacted by stamp duty changes, and in car manufacturing. Investor skepticism regarding the government's spending plans is reflected in higher borrowing costs, as highlighted by Quilter, with concerns over potential future tax rises likely to further weigh on growth. Businesses, particularly in sectors like hospitality, are already reporting pressure from cumulative cost increases including National Insurance, minimum wage, and business rates. Although the government has secured a tariff deal with the US and other trade agreements, existing tariffs, such as the 10% import tax on most UK goods entering America, continue to affect trade until full implementation.

Key Decisions for Investors

• Investors should maintain a cautious stance on UK-exposed assets, particularly within consumer discretionary and domestically-focused service sectors, given the negative economic data and the prospect of further fiscal tightening.
• Closely monitor the autumn Budget for definitive tax and spending policies, as these will be pivotal for market direction and the UK's economic outlook.
• Consider potential currency headwinds for GBP resulting from the weakening economic outlook and increased borrowing, and evaluate hedging strategies for sterling exposures.
• Focus on companies with diversified international revenue streams or those in non-cyclical sectors with strong pricing power that may offer resilience against domestic economic pressures and tax changes.
