The U.S. dollar has weakened significantly in recent weeks, reaching a five-month low against the euro, trading near $920. This decline is attributed to growing concerns about the global economic outlook and recent announcements from China that have raised worries about economic performance in the U.S. The dollar's depreciation has been accompanied by a drop in commodity prices, with copper hovering around $5 per pound. Analysts note that the U.S. dollar's struggles are linked to fears of a slower economic growth rate, which is affecting market sentiment.
