Britain’s 2026 Forecast Improved. The IMF Still Sees a Tighter 2027.

The IMF now expects the U.K. economy to grow 1.3% in 2026, up from the 1% it forecast in July, the BBC reported on October 13. It expects growth to slow to 1.2% in 2027 as higher energy prices and long-term interest rates restrain household spending and business investment. Its inflation forecast averages 3.3% this year and 2.8% next year. The next-year inflation figure was raised from 2.4%.

On October 14, Managing Director Kristalina Georgieva said Britain had acted decisively to reduce its deficit and, in that sense, had a somewhat better growth prospect. The BBC reported that the IMF sees the U.K. as the only G7 country with a substantial multi-year borrowing reduction, nearly 4% of the economy. These are forecasts. Chancellor John Healey’s October 28 Budget will use the Office for Budget Responsibility’s projections, not the IMF’s.

The U.S. connection is indirect. The same energy-price and interest-rate pressure the IMF cites for Britain is already visible in U.S. inflation and Treasury yields. The U.K. forecast itself did not establish a U.S. price change.

Does the upgraded U.K. forecast mean energy bills will fall? No. The IMF raised its 2026 growth number but said higher energy prices and interest rates are expected to slow Britain in 2027. It announced no bill cut.
