Euro declines ahead of ECB rate decision

Euro retreated on Thursday against dollar to near four-week lows ahead of the European Central Bank's policy meeting. 

EUR/USD declined 0.1% to 1.1079, after closing up 0.1% on Wednesday, the second profit in three days. 

Euro plumbed a four-week low yesterday at 1.1070 after US President Donald Trump threatened tariffs on European products if no "fair" trade deal was reached. 

US tariffs would probably lead to European retribution, in turn nudging the ECB to ease policies and pressure the euro further down. 

Analysts expect the European Central Bank to leave rates and policy unchanged for the day while shedding light on the future of their plans, especially as the US-China trade war risks subsidized.
