European Central Bank President Mario Draghi on Tuesday highlighted the central bank’s dovish message on monetary policy, indicating that it could extend its bond-buying program if necessary. The ECB’s “anticipated ending of asset purchases in December this year is subject to incoming data confirming the medium-term inflation outlook,” Draghi said in speech at the bank’s annual economic conference in Sintra, Portugal. “Moreover, the [asset-purchase program] can always be used in case contingencies materialize that we do not currently foresee,” he said. The ECB last week said it would purchase €30 billion ($34.6 billion) a month of bonds through the end of September, and if data met its medium-term inflation outlook, it would reduce purchases to €15 billion a month through the end of December, then end them. Interest rates would remain at their ultra-low levels through at least the summer of 2019, the ECB said last week. The euro extended losses after Draghi’s remarks on Tuesday, trading at $1.1546 compared with $1.1624 late Monday in New York.
