IMF Upgrades UK Growth Forecast to 1% Amid External Shocks
The International Monetary Fund raised its 2026 real-GDP growth projection for the United Kingdom to 1.0 % from 0.8 % in its latest review. The modest lift reflects stronger-than-expected pre-war momentum, recent data revisions and a 0.6 % Q1 rebound in retail and construction. The Fund still notes a slowdown relative to 2025 but says the economy “remains resilient” despite heightened external volatility.
Energy Dependence, Iran Conflict, and Political Turmoil
Britain imports more energy than it produces, making it sensitive to global price spikes. The IMF flagged war in Iran as a source of higher energy and food costs that could dampen short-term growth. Labour’s local-election setbacks and speculation over Prime Minister Keir Starmer have raised “domestic uncertainty”, pushing gilt yields to their highest level since 2008.
Core Numbers
Growth: 1.0 % (2026). Inflation: just under 4 % by year-end, falling to 2 % by end-2027. Bank of England rate: 3.75 %; IMF advises holding rates for the year. Fiscal plan: balanced non-investment budget by 2029/30 with continued deficit-reduction. Energy-price assumptions rely on expected global declines.
Government and IMF Responses
Chancellor Rachel Reeves called the upgrade proof that the government’s economic plan is “right” and said her fiscal choices have strengthened the economy to absorb Iran-related costs. IMF mission chief Luc Eyraud stressed that markets value predictable policy and that the UK’s borrowing-rule commitment underpins its financial credibility. The Fund reiterated that the Bank of England can meet the 2 % inflation target without further rate hikes if energy prices ease.
Political Uncertainty and Market Concerns
The IMF warned that domestic uncertainty could compound the volatile global environment, suppressing consumption and investment. Analysts note that speculation over Starmer’s leadership has lifted borrowing costs to multi-year highs, raising doubts about fiscal discipline. The Fund said stronger second-round inflation could force the central bank to respond forcefully, either by cutting or raising rates.

> “Today's policymaking is constrained by a more volatile external environment with more frequent and overlapping shocks, a rising public interest bill, in part reflecting market concerns with countries' elevated debt, and the long-standing challenge of weak productivity growth,” — Luc Eyraud, IMF mission chief

> “The choices I have made as chancellor mean our economy is in a stronger position as we deal with the costs of the war in Iran,” — Rachel Reeves, Chancellor
Outlook
The IMF advises the Bank of England to be ready for “forceful” action if wage pressures or price pass-through intensify, while urging that any energy-price support be targeted, time-limited and financed through tax adjustments or spending cuts. The government is expected to detail cost-of-living measures, including a possible cancellation of a planned fuel-duty rise, as it pursues its deficit-reduction trajectory.
