European stock futures and shares rallied to a four-month high following the announcement of a trade deal between the United States and the European Union. The agreement lifted market sentiment globally, contributing to gains in European equities from the opening bell. Concurrently, the US dollar strengthened against major currencies, including the euro, which came under pressure and experienced its strongest decline in two months. Despite the initial positive market reaction to the trade pact, the euro's value continued to fall as traders reassessed the deal, leading to a mixed response in European stock markets with some closing lower. Analysts noted the unusual continued rise of the US dollar following the deal, signaling a shift in currency dynamics and challenging previous strength in the euro.
