IMF Lifts UK Growth Forecast as Chancellor Gains Fiscal Breathing Room

By Olivia Hart

The IMF has raised its growth forecast for the UK, handing the chancellor a rare piece of good economic news at a moment when the fund believes global resilience is fraying. The upgrade landed alongside the launch of the IMF's latest report, delivered in Bangkok by Silvana Tenreyro, the fund's economic counsellor.

Tenreyro did not soften her warning about the broader picture. "The global economy has been resilient, but that resilience is reaching its limits," she said. Her prescription for policymakers was blunt: "move from just coping, to rebuilding."

What did the IMF say about the UK specifically?

The UK drew an unusual distinction. Tenreyro, a former member of the Bank of England's monetary policy committee, said the UK "stands out" from other G7 countries because it has a plan to repair its public finances. That is a pointed comparison: the G7 groups the world's largest advanced economies, and being singled out for fiscal planning — not just fiscal performance — is the sort of endorsement chancellors quote for months.

The caveat writes itself. A plan is not a result, and Tenreyro's own framing — resilience "reaching its limits" — signals that the fund sees the margin for error narrowing, not widening. An upgraded forecast is a snapshot of expectations, not a guarantee of delivery.

Why does the forecast revision matter politically?

For the chancellor, the timing matters as much as the substance. A higher growth projection from the IMF gives fiscal headroom arguments more weight, because faster growth feeds tax receipts and eases debt-to-GDP arithmetic. The Guardian framed the revision explicitly as a boost for the chancellor, and the endorsement of the UK's fiscal repair plan from a former Bank of England rate-setter carries institutional weight on both sides of that debate.

Still, an IMF upgrade has a mixed record as a political talisman. Forecasts get revised down as readily as up, and Tenreyro's warning about global limits applies to the UK too. What the fund gives in October it can take back in the spring.

Who is Silvana Tenreyro?

Her credibility here rests on more than the IMF title. Tenreyro sat on the Bank of England's monetary policy committee, the nine-person body that sets UK interest rates. She has since moved to the IMF's top economic counselling post, giving her a view of both UK policy machinery and the global picture she sketched in Bangkok.

That dual perspective sharpens the "stands out" comment. It comes from someone who knows the UK's fiscal institutions from the inside, not from a distant desk in Washington.

What happens next?

The revision itself is the hard fact; the delivery is the open question. Tenreyro's call to "move from just coping, to rebuilding" sets the test the UK's fiscal plan will now be judged against — whether repair turns into results before the global runway she describes runs out.
