IMF upgrades UK 2026 growth outlook but warns of slowdown in 2027

The International Monetary Fund (IMF) has revised its outlook for the United Kingdom, projecting a 1.3% expansion of GDP in 2026 – up from the 1% forecast issued in July. The agency, whose reports are closely monitored by the British government, also cautions that growth will decelerate to about 1.2% in 2027 as higher energy prices and long‑term interest rates weigh on household spending and business investment.

Debt management and borrowing outlook

IMF chief economist Silvana Tenreyro told BBC News that the United Kingdom is now leading the G7 in managing its debt burden. She noted, “the UK has already started the consolidation process and it is the country that basically stands out, along with India.” The Fund predicts the UK will cut its annual borrowing by nearly four percentage points of GDP between 2025 and 2031 – a reduction far larger than the rest of the G7, many of which are projected to increase deficits.

By 2031, the IMF expects the UK to have the lowest annual borrowing among the G7 and to hold the longest maturity profile for its debt, effectively locking in lower interest rates for a longer period. When asked whether the IMF was urging the UK to further reduce borrowing, Tenreyro affirmed that the country had already begun the process and should “stay the course.”

Policy response and political reactions

Chancellor John Healey, preparing the new‑look government’s tax and spending plans slated for announcement on 28 October, said the Budget will aim to “provide some breathing space” for households. Healey acknowledged that wars in the Middle East and Europe are “hitting people in the UK and around the world,” but added that Britain’s economy is showing “strong international resilience.”

Financial markets are watching closely as borrowing costs have surged, putting pressure on the chancellor to keep fiscal plans credible. Healey is also scheduled to meet other finance ministers at the IMF’s annual gathering in Bangkok, Thailand, to discuss ways to limit the economic fallout from Middle‑East and European conflicts.

Commentators offered mixed views on the IMF’s upgrade. Maike Currie, head of personal finance at Pension Bee, told the BBC that the report “does give the chancellor a little bit of breathing space” but warned it is not a “game‑changer” for families. The Resolution Foundation urged the chancellor to “make repairs” to public finances while providing targeted support for those struggling to heat their homes.

Conservative shadow chancellor Andrew Griffith warned that any move toward additional tax rises in the Budget would “choose slower growth” and place the burden on working people.

Inflation and household pressures

The IMF expects inflation to average 3.3% in 2024 and remain above the Bank of England’s 2% target in 2027, at about 2.8%. The Bank itself has warned that inflation could climb above 4% early next year, raising the likelihood of further interest‑rate hikes. The Fund highlighted that, despite these pressures, the global economy has demonstrated a “remarkable capacity to absorb shocks” from the current Middle‑East conflict, the Covid‑19 pandemic and Russia’s invasion of Ukraine.

Overall, the IMF’s revised forecast paints a cautiously optimistic picture for the UK in the near term, while underscoring the challenges that higher energy costs and debt dynamics will pose to sustained growth beyond 2026.
