UNITED States consumer inflation jumped 0,4% in September, the biggest increase in five months, reflecting sharply higher prices for gasoline, cigarettes and clothing. The gain, however, was in line with analysts’ forecasts, calming investors who were nervous after last week’s jump in producer prices. Rising worries about inflation have set off alarm bells on Wall Street with investors concerned that the Federal Reserve will be forced to raise interest rates again at their next meeting on November 16. The Fed has already boosted borrowing costs twice this year in an effort to keep the economy from overheating.
