The UK's Office for Budget Responsibility warns that any percentage point change in interest rates could shift the interest costs of government debt by £16bn, as persistently high energy prices threaten to push up inflation. - OBR forecasts inflation of 3.5% in 2027, up from 2% previously, with a quarterly peak of 3.75% expected in early 2027. - If energy prices will remain higher for longer, inflation may rise further, near-term GDP growth may weaken, and financial conditions may tighten.
