Forecast downgrades

Official forecasters and economists downgraded growth expectations, with the Office for Budget Responsibility trimming its projection for the year and private-sector economists warning growth may be elusive.

The BBC said "In the Spring Statement in March, the Office for Budget Responsibility (OBR) - the government's official forecaster - cut its prediction for how much the UK's economy would grow this year to 1.1% from 1.4%."

Costs and monetary policy

Rising costs and geopolitical developments have shifted monetary expectations: higher energy prices and increased government borrowing costs are weighing on the outlook, and what the BBC calls the "Iran conflict" has already altered market expectations about Bank of England action.

The BBC reported that activity was expected to "weaken further amid sharply rising energy prices" and that "government borrowing costs have risen in recent weeks."

It added that "Before the Iran conflict, analysts had said the Bank of England could cut interest rates as soon as March, but they now widely expect a hold when it meets next week."

Business outlook

Higher-for-longer interest rate expectations and rising costs are likely to act as a headwind for businesses, prompting scaled-back investment plans, according to the BBC coverage.

The BBC said "Keeping interest rates higher for longer will be a 'headwind' for businesses" and warned that "expectations for weaker growth plus rising costs meaning firms are likely to scale back investment plans."
