Falling inflation in the UK helped the FTSE 100 Index jump almost 1 per cent as the case for low interest rates hardened.
The Footsie was up 60.43 points at 6,796.43, also helped by a fresh round of stimulus from the Bank of Japan and speculation that the eurozone’s own problem with low inflation would have to be addressed.
Alex Conroy, financial trader at Spreadex, said: “Investors are positioning themselves for the increasing possibility of a European version of quantitative easing in response to the growing threat of deflation.”
Scottish Gas-parent Centrica endured more share losses after broker UBS slapped a “sell” rating on the firm just two days before its annual results, due tomorrow.
