Most City experts believe Kenneth Clarke, Chancellor of the Exchequer, decided to leave base rates unchanged after his meeting yesterday with Eddie George, Governor of the Bank of England. Although the meeting ended too late to be sure of the outcome, Mr Clarke was expected to turn down the Bank's advice to increase the cost of borrowing by a quarter of a percentage point to 6 per cent.
However, the balance of the decision in the US is expected to tilt in favour of higher interest rates.

Shares on Wall Street fell sharply enough to trigger the New York Stock Exchange's curbs on automated deals.

The Federal Reserve is expected, by a small majority of analysts, to raise rates by at least a quarter point because the US economy has managed to defy predictions that it would slow down in the second half of this year.

The Bank of England's concern about higher inflation in Britain beyond the next few months, following the pick-up in the pace of economic activity, is shared by many City experts.
James Barty, UK economist at investment bank Deutsche Morgan Grenfell, said: "If the Bank called for an increase in interest rates at this meeting, I am very sympathetic. But obviously the Chancellor would like to avoid it if at all possible."
