European Central Bank chief Mario Draghi said the ECB was "ready to take decisive action if required." According to dpa, this could follow an unwarranted tightening of market liquidity or a worsening in the inflation outlook, he said. But, for the moment, he said interest rates in the eurozone would remain at "present or lower levels for an extended period," Draghi said. This was based on expected subdued economic growth, as well as projections of a prolonged period of inflation, the ECB chief said.
