Medium to longer-term inflation expectations remain firmly anchored in line with the Governing Council's aim of keeping inflation rates below, but close to 2 percent over the medium term.
At the same time, the latest information continues to signal an improvement in economic activity in the second half of this year, Trichet said.
The Governing Council expects the euro area economy in 2010 to recover at a gradual pace, recognizing that the outlook remains subject to high uncertainty.
The Governing Council also left interest rates on the marginal lending facility and the deposit facility unchanged at 1.75 percent and 0.25 percent respectively.
