The U.S. dollar has plunged more than 10% over the past six months — its steepest decline against a basket of major trading partners’ currencies since 1973. The dollar now sits at a three-year low.The main reason? Global investors no longer expect the U.S. economy to outperform the rest of the world. President Donald Trump’s tariffs and worsening fiscal outlook have weighed on growth expectations. Although U.S. stocks have hit record highs, equities in other countries have performed even better. Meanwhile, returns on lending to the U.S. are expected to decline as growth slows.This outcome has surprised many, including members of Trump’s own Cabinet, who believed tariffs would strengthen the dollar by reducing Americans’ purchases of foreign goods. Instead, weaker U.S. growth has made U.S. debt less attractive to foreign investors, especially compared to countries like Germany and Japan, which are now expected to grow faster.A weaker dollar has pros and cons:Exports: U.S. goods become cheaper abroad, potentially boosting exports.Travel: Americans traveling overseas will find their dollars buy less.Inflation: Imported goods become more expensive, eroding consumers’ purchasing power and adding to inflationary pressures.While Trump’s tariffs led U.S. firms to stock up on imports earlier this year to avoid new duties, it’s too early to tell if exports are rising. Upcoming second-quarter data may offer a clearer picture.A deeper problem, analysts warn, is that foreign investors are pulling back from U.S. financial assets. The U.S. has long relied on foreign capital to finance its trade deficit and support stock and bond markets. A weaker dollar could discourage these investors further.Bob Elliott, chief investment officer at Unlimited Funds, explained: “It’s often forgotten that the U.S. depends not only on foreign goods but also on foreign capital. If foreigners stop buying U.S. stocks and bonds, it could hurt Americans’ wealth.”Bank of America analysts Hubert Lam and Christiane Holstein noted that investors are shifting money away from the U.S. into European markets, citing concerns over protectionist policies, rising deficits, and proposals for new taxes on foreign investors.However, some analysts believe fears of prolonged dollar weakness are overblown. They argue U.S. economic strengths, like dynamic markets and pro-growth regulations, will eventually stabilize the currency. Trump’s tax cuts and recent data showing a resilient U.S. labor market have given the dollar a brief boost.Still, if U.S. growth continues to slow, the Federal Reserve may cut interest rates, making U.S. assets even less attractive to global investors — and further weakening the dollar. That would raise the cost of imported goods, fueling inflation.Danny Dayan, an investor, summed it up: “It’s a doom loop. A weaker dollar raises import prices, which adds to inflation.”For now, while inflation remains moderate, the combination of tariffs and a falling dollar could soon push prices higher — creating new challenges for American consumers and businesses.
