The OECD has upgraded its forecast for the UK economy, citing policy changes and inflation risks, while cautioning that limited fiscal space could hinder future resilience.

A Brighter-but Fragile-Path Ahead

Britain may be heading into a slightly stronger economic stretch than once expected, according to new projections from the Organisation for Economic Co-operation and Development (OECD). The international body, in its latest global outlook released Tuesday, signaled that the UK’s growth prospects for next year have improved yet emphasized that the road ahead remains lined with significant inflation pressures and limited fiscal flexibility.

A Shift in Economic Expectations

The Paris-based OECD upgraded its 2026 growth outlook for the United Kingdom, now forecasting a 1.2% expansion compared with the 1% predicted in September. The organization expects growth to rise modestly again in 2027, projecting a 1.3% increase in gross domestic product (GDP).

The improved outlook, the OECD said, reflects the impact of Finance Minister Rachel Reeves’ recent fiscal measures particularly those aimed at stimulating consumption. However, it also warned that global uncertainty and persistent domestic price pressures could complicate Britain’s recovery trajectory.

Budget Measures Reshape the Economic Landscape

Chancellor Rachel Reeves’ November 26 budget boosted spending across several sectors, backed by a mix of higher government borrowing and tax increases targeting workers, pension savers, and investors. The OECD noted that these policy decisions will influence the pace of economic consolidation in the coming years.

The organization stressed that fiscal tightening should be “carefully timed” and balanced across both revenue-generating tools and targeted spending cuts to avoid risking further inflation or hampering growth.

Reeves, responding to the updated forecasts, highlighted what she viewed as early positive indicators from the budget, pointing to reductions in National Health Service (NHS) waiting lists, lower borrowing levels, and broader efforts to ease living costs.

Inflation Remains the Stubborn Challenge

Despite the slightly better growth trajectory, Britain continues to wrestle with some of the highest inflation levels among G7 nations. The OECD expects consumer prices to average 3.5% in 2025 a rate that outpaces other advanced economies before easing to 2.5% in 2026 and 2.1% in 2027.

The projection for next year lines up with estimates released by the UK’s independent budget watchdog last week, underscoring broad agreement among financial institutions about the persistence of elevated price pressures.

Even as inflation appears to be decelerating, the OECD warned that price expectations remain high. It also pointed to possible “second-round effects” triggered by rising payroll taxes, increases in the minimum wage, and stubbornly high food costs all of which could slow progress in returning inflation to the Bank of England’s 2% target.

What the OECD Says About Interest Rates and Risks

With inflation moderating at a slower pace than the government might hope, the OECD signaled that the Bank of England may be compelled to keep interest rates elevated for longer. Such a stance, while aimed at stabilizing prices, could ultimately dampen consumer spending and weigh on the broader recovery.

“Upside risks to inflation,” the OECD noted, may leave policymakers with little room to pivot to a looser monetary stance. This, in turn, would pose “downside risks to economic growth.”

Public Finances Under Strain

Another key concern raised in the report involves the UK’s fiscal position. The OECD expects Britain’s government deficit to remain sizable through the middle of the decade. While the deficit is projected to narrow from 5.9% of GDP in 2025 to 5.1% in 2027, the organization emphasized that the reduction is gradual and leaves little room for maneuver if the country faces economic shocks.

Total government revenue, it said, is expected to reach roughly 40% of national output by 2027.

The warning underscores a broader theme: although the UK may be moving toward steadier growth, it faces a constrained fiscal environment that limits its ability to respond to unexpected downturns or global volatility.

Balancing Act Ahead

The OECD urged the British government to maintain a cautious approach to fiscal consolidation. Crafting the right policy mix raising revenue without overly burdening households and cutting spending without undermining public services will be essential as inflation risks linger.

Reeves, for her part, embraced the OECD’s updated assessment as validation of her budget strategy. She argued that the government’s measures are already demonstrating progress on long-standing challenges such as health-care delays and household affordability.

Broader Implications for Households and Businesses

For British households, the OECD’s outlook points to slower relief from inflation than many might hope for, meaning living costs could stay elevated into the middle of the decade. Businesses, meanwhile, may continue to wrestle with high borrowing costs if interest rates do not ease soon.

Internationally, the UK’s tempered but positive growth forecast positions it as a modest outperformer among several major European economies, though still trailing the stronger momentum seen in the United States.

A Cautious Optimism Defines the UK’s Path

The OECD’s upgraded forecast offers a dose of optimism for Britain’s medium-term economic health. Yet it also casts a spotlight on the delicate balance ahead managing inflation, navigating global uncertainty, and stabilizing public finances without derailing growth. As the UK charts its course through a volatile global landscape, policymakers will face a demanding set of choices that could shape the nation’s economic future for years to come.
