ECB won't be too hasty in ending bond buys: Coeure

With the euro zone economy booming and employment at record highs, pressure has been building on the bank to curb stimulus as the 19-member currency bloc is close to exhausting its spare capacity.

"Of course (quantitative easing) will not last forever but there is also a very wide agreement in the Governing Council ... that we have to be patient and prudent because we are not yet where we want to be in terms of inflation," Coeure said in question and answer session after a speech in Dublin.

"We are not going to be too hasty," he added.

The ECB targets inflation at just below 2 percent and its projections suggest it will undershoot this objective at least through 2020, underpinning its caution.

While the bank has signaled that a discussion could soon start about tweaking its policy guidance, Coeure said policymakers were not yet there.

"We are having a discussion on having a discussion; its meta monetary policy," he said. "There has been much hype around disagreements in the Governing Council (but) any nuances in the Governing Council are as to when next to communicate."

Still Coeure acknowledged that the euro zone expansion is robust, providing support for the ECB's optimism that inflation will rise back to its target in the medium term.

While some have argued that extended stimulus could eventually push inflation too high, Coeure said that bond market pricing suggests that investors are "deeply skeptical" that inflation can surprise much on the upside in the future.
