The European Central Bank (ECB) is ready to do what it takes to keep its medium-term inflation target on course, its head Mario Draghi said in a newspaper interview published on Saturday. Consumer prices in the 19-country euro zone slipped by 0.1 percent in September – far from the bank’s aim of just below 2 percent – prompting calls for the ECB to expand or extend its 60 billion euros a month of asset purchases. “If we are convinced that our medium-term inflation target is at risk, we will take the necessary actions,” Draghi told the Italian daily Il Sole 24 Ore.
