The euro steadied near its lowest in a month on Wednesday, nursing steep losses this week as investors counted the cost of the U.S.-EU trade pact and looked ahead to policy meetings from the Federal Reserve and the Bank of Japan.

The Europe trade deal will see the U.S. impose a 15% import tariff on most EU goods − half the threatened rate but much more than Europeans hoped for.

"I think it's the biggest deal ever made," Trump said of the new agreement, which will reduce the bloc's tariff rate to 15 percent.
