ECB keeps rates unchanged, awaits update on inflation outlook
The decision to leave rates unchanged was expected, as ECB policymakers await updated economic forecasts from the bank's staff in June to assess whether to act to counter low inflation that risks becoming stuck in a "danger zone" below 1 percent.
The ECB also left unchanged the rate it pays on bank overnight deposits at 0.0 percent, and held its marginal lending facility - or emergency borrowing rate - at 0.75 percent.
Markets now turn their attention to ECB President Mario Draghi's 8:30 am ET (1230 GMT) news conference, at which he is expected to give a more detailed explanation for the ECB's decision.
