"The ECB's 2% inflation target has essentially been achieved," Estonian policymaker Madis Müller said. "The expected economic growth in the next couple of years is also likely to be quite moderate, which means that there is no reason to worry too much about price pressure related to the heating up of the economic environment."

The European Central Bank cut some of its growth and inflation projections on Thursday as the fallout from a global trade war is likely to prove a drag for the 20-nation euro zone.

The key interest rate was cut by a quarter point to 2% on Thursday, but the monetary cycle is 'coming to an end,' said European Central Bank president Christine Lagarde.
