Since climbing to a seven-month high on Aug. 24, the euro has slid almost 5 percent as ECB officials including President Mario Draghi reiterated their willingness to respond to threats of missing their inflation target. Executive Board member Peter Praet said on Monday that the institution would “certainly do what’s necessary” if its inflation objective were to be at risk. The yen advanced against all of its 16 major counterparts as European shares retreated with U.S. equity-index futures and commodities.
