But Mike Bell, global market strategist at J.P. Morgan Asset Management, said that due to solid economic growth and an expected fall in unemployment across the eurozone, "the European Central Bank are likely to feel comfortable ending QE in September".

Trump on Thursday afternoon is expected to sign off on its tariff plan, White House National Trade Council director Peter Navarro told broadcaster Fox Business on Wednesday.

"Talk of greater available slack and the clear easing of inflation pressures has taken the pressure off the committee to act, and with a typically dovish Mario Draghi allowed to maintain an accommodative stance going forward, today is clearly a case of taking with one hand and giving with the other", he wrote.

"In this context (of subdued underlying inflation), the Governing Council will continue to monitor developments in the exchange rate and financial conditions with regard to their possible implications for the inflation outlook".
