Wall Street stocks and Hong Kong shares in London surged yesterday after economic figures released in Washington revealed inflation was still under control, despite an expanding US economy. The Dow Jones Industrial Average climbed 1.38 per cent, or 89.1 points to 6,541 points, triggering index-arbitrage curbs after the Dow jumped more than 50 points at the start of trade. The Hang Seng London Reference Index soared 138.66 points, or 1.12 per cent, to end at 12,480.68 points. Traders said the jump was inspired by the release of US consumer price data, which showed a 0.1 per cent rise in consumer prices in March, confounding expectations of a 0.2 per cent rise. The result was a sharp reversal of the 0.3 per cent rise recorded in February, but economists said it would not sway the Federal Reserve from tightening interest rates.
