The U.S. dollar has dropped about 10% against a basket of other major currencies since early 2025. That shift is starting to show up in everyday costs: A weaker dollar means Americans get less when traveling abroad and may pay more for imported goods like food, fuel and electronics. Economists say the effect on prices is usually modest, but it can add up, particularly when stacked on other factors, including inflation, tariffs and a spike in fuel costs due to the Iran war. President Donald Trump has openly supported a weaker dollar, arguing it helps American industry, and some executives agree, saying it's boosted overseas business.
