- IMF Cuts UK Growth Outlook To 1.00% As Middle East War Lifts Energy Risks
The International Monetary Fund has warned that the United Kingdom’s near-term economic outlook has weakened as the war in the Middle East pushes energy prices higher, squeezes real incomes and complicates monetary policy at a time when the economy had begun to regain momentum.
In its 2026 Article IV Consultation with the UK, concluded by the IMF Executive Board, the Fund projected real GDP growth to slow from 1.40% in 2025 to 1.00% in 2026, before recovering gradually to 1.30% in 2027 and 1.70% in 2028.
The IMF said the UK economy had remained resilient, supported by prudent policies and a recovery in private consumption and investment before the latest external shock. Growth had picked up to 1.40% in 2025, while core inflation eased and wage growth moderated, allowing the Bank of England to reduce the Bank Rate to 3.75% by February 2026.
But the fallout from the Middle East conflict has weakened the outlook. Higher energy prices are expected to erode household purchasing power, tighten financial conditions and weigh on demand. The IMF now expects headline inflation to peak above 3.50% toward the end of 2026 before returning to target toward the end of 2027.
The Fund’s central message is that UK policymakers face a difficult balancing act: supporting economic resilience without allowing the energy shock to become embedded in core inflation and wage-setting behaviour.
The IMF said monetary policy should remain “sufficiently restrictive” to contain second-round effects from higher energy prices, with decisions remaining data-dependent and taken meeting by meeting because of heightened uncertainty.
That recommendation suggests the Fund does not see room for premature policy easing. Even though growth is slowing, the risk that energy-driven inflation spills into broader prices and wages means the Bank of England must continue to prioritise inflation credibility.
The IMF’s inflation projections show period-average CPI easing only gradually, from 3.40% in 2025 to 3.20% in 2026 and 2.40% in 2027, before returning to 2.00% from 2028 onward. End-period CPI is projected at 3.50% in 2026 and 2.00% in 2027.
The labour market is also expected to weaken. The unemployment rate is projected to rise from 4.90% in 2025 to 5.60% in 2026, before declining to 5.30% in 2027 and 4.80% in 2028. The IMF said weak labour market conditions, slower wage growth and a negative output gap should limit the pass-through of higher energy prices into core inflation.
On fiscal policy, the IMF gave a broadly positive assessment of the authorities’ strategy, saying it strikes an appropriate balance between deficit reduction and growth-friendly spending. The Fund welcomed changes to the fiscal framework that strengthen predictability, but urged the government to stay the course on consolidation.
The UK’s public sector overall balance is projected to improve from a deficit of 4.30% of GDP in FY2025/26 to 4.00% in FY2026/27, 3.30% in FY2027/28 and 2.80% in FY2028/29. Public sector net financial liabilities, however, are expected to rise from 82.80% of GDP in 2025 to 83.90% in 2026 and 84.40% in 2027 before gradually easing later in the projection period.
The IMF said any response to the energy shock should remain tightly targeted, temporary and budget-neutral. That warning reflects the limited room for broad-based fiscal support, especially as the UK faces medium- to long-term spending pressures from ageing, defence and the energy transition.
Directors also stressed the need for upfront contingency measures in case the outlook deteriorates or fiscal delivery falls short. This is important because the UK’s fiscal strategy depends heavily on sustained implementation, spending discipline and confidence in the government’s ability to meet its medium-term objectives.
The IMF also noted that risks to growth are tilted to the downside. The main threat is a prolonged disruption to energy supply. Other risks include larger inflation second-round effects, tighter credit conditions, policy uncertainty, worsening external conditions, renewed trade tensions and tighter global financial conditions.
There are some upside possibilities. The IMF said stronger growth could come from households drawing down savings faster than expected or from productivity gains linked to quicker adoption of artificial intelligence. But the Fund’s overall assessment suggests that the immediate risks remain more negative than positive.
Beyond the near-term shock, the IMF placed heavy emphasis on structural reforms. It said the UK’s reform agenda covers the right areas, including skills shortages, labour mobility, migration policy, artificial intelligence adoption, energy security and diversified trade ties.
The Fund’s caution is that reform ambition alone will not raise productivity. Delivery will depend on prioritisation, sequencing, sustained implementation, systematic monitoring and transparent reporting of progress.
This point goes to the heart of the UK’s long-term economic challenge. Growth has been constrained not only by shocks but by weak productivity performance. Without a stronger supply-side reform push, the economy risks remaining trapped in a cycle of modest growth, high public spending pressures and limited fiscal flexibility.
The IMF also said the UK financial system appears resilient, while noting elevated global risks. It welcomed the authorities’ role in addressing risks from the nonbank financial sector and supported efforts to make the financial sector a stronger engine of investment and productivity. However, it urged a cautious approach to regulatory reform and encouraged continued strengthening of the anti-money laundering and counter-terrorist financing framework.
For markets, the IMF’s assessment reinforces three signals. First, UK growth is slowing but not collapsing. Second, inflation risks remain sufficiently serious to justify restrictive monetary policy. Third, fiscal credibility and reform delivery will be central to sustaining investor confidence.
The UK economy may have entered 2026 with resilience, but the IMF’s warning is clear: external shocks have narrowed the policy space. The government must maintain fiscal discipline, the Bank of England must guard against entrenched inflation, and structural reforms must move from ambition to execution.
The next phase of the UK recovery will therefore depend less on short-term stimulus and more on credible policy delivery, energy resilience and productivity-enhancing reform.
