The US dollar closed the first half of 2025 with its worst performance since 1973, tumbling roughly 11% against a basket of major currencies as tariff turmoil and pressure on the Federal Reserve weighed on the greenback. For large US multinationals with substantial overseas revenue, the slide flipped a currency headwind into a tailwind just as second-quarter earnings season got underway, widening the gap between globally exposed companies and their domestically focused peers.
The Dollar's Historic Slide
The ICE US Dollar Index fell about 10.8% between January and the end of June 2025, according to Bloomberg data, marking its steepest first-half decline since the gold standard era ended in 1973. The greenback fell 14.4% against the Swiss franc, 13.8% against the euro and 9.7% against the British pound over the same period, illustrating how broadly the decline was distributed across major currency pairs. Analysts at Morgan Stanley projected further depreciation into 2026, arguing that converging US interest rates and growth with the rest of the world would keep the currency under pressure well beyond the summer.
Tariffs, Rate-Cut Pressure and Policy Uncertainty
The dollar's decline traced directly back to President Trump's on-again, off-again tariff announcements, which unsettled investors' confidence in US trade policy and, by extension, in dollar-denominated assets. Compounding the pressure, Trump repeatedly pushed the Federal Reserve to cut interest rates faster than officials were prepared to move, feeding speculation about central bank independence. Together, these forces eroded the currency's traditional safe-haven premium. Some strategists framed the drop as a symptom of eroding confidence in US fiscal and monetary credibility rather than a simple cyclical adjustment, describing it as a quiet but consequential repricing of dollar assets.
A Currency Tailwind Splits Corporate America
As second-quarter results rolled in, the weaker dollar became one of the biggest tailwinds cited by US companies with significant international sales. Levi Strauss, Netflix, PepsiCo and 3M each pointed to favorable currency translation as a boost to reported revenue and profit, since overseas earnings converted into more dollars once repatriated. Estimates suggested dollar weakness added more than 60 basis points to aggregate S&P 500 earnings growth in the quarter. Domestically focused firms with limited foreign exposure saw no such lift, sharpening the divide between globally diversified multinationals and companies reliant mainly on the US consumer.
What It Means for Traders
For currency traders, the dollar's 2025 slide underscored how tariff headlines and Fed commentary can move markets as much as traditional data releases. A softer dollar also reshaped relative-value opportunities across EUR/USD, USD/JPY and emerging-market pairs, while equity investors increasingly screened for revenue exposure by geography before positioning. With Morgan Stanley and other banks flagging further downside into 2026, monitoring trade-policy headlines, Fed rhetoric and earnings guidance became essential for anyone trading dollar pairs or US equity indices through the second half of the year.
