The value of the U.S. dollar has experienced a significant and historically rare decline in the first half of 2025, marking its weakest start to a year in over half a century. Financial markets and analysts widely attribute this sharp depreciation to a confluence of factors, most notably the economic policies and geopolitical approach adopted by the Trump administration. This slump challenges the dollar’s traditional role as a global safe haven and signals a potential shift in international asset allocation preferences.
Since the start of the year, the dollar has weakened substantially against a basket of major global currencies. The widely tracked ICE U.S. Dollar Index has fallen by more than 10 percent over the past six months. This downturn is the worst first-half performance recorded since 1973. That earlier decline occurred after a “seismic shift” – the United States ended the linking of the dollar to the price of gold under the Bretton Woods system. This time, the market turbulence appears driven by a different kind of policy upheaval.
A Historical Low Point for the Greenback
The dollar’s more than 10 percent slide in the first half of 2025 puts it on track for its weakest performance over any six-month period since 2009. Compared to the over 15 percent loss seen in the first half of 1973, the current 10.4 percent decline year-to-date (as of June 30th, 2025) is less severe numerically but equally significant historically as the worst start to a year in over 50 years. The dollar index is now trading near the 97 mark, a notable drop from its 52-week peak around 110. This sustained downward pressure reflects deep-seated concerns among global investors.
While import tariffs might typically be expected to strengthen a currency by making imports more expensive and boosting demand for domestic goods, the specific nature of Trump’s trade approach seems to have had the opposite effect on the dollar. His “America first” policy, characterized by unilateral actions, individualized “reciprocal” tariffs, and sudden shifts in negotiation stances, has been described as “disordered” and “erratic.” This volatility, combined with other policy concerns, appears to have undermined confidence rather than built strength.
Key Policy Drivers Behind the Dollar’s Drop
Several specific aspects of President Trump’s agenda are frequently cited as primary contributors to the dollar’s weakening trend. These factors include the aggressive use of tariffs and the uncertainty surrounding trade policy, concerns about rapidly rising government debt, and perceived pressure on the independence of the Federal Reserve.
Trade Policy and the “Start-Pause Tariff War”
President Trump’s reliance on tariffs as a key foreign policy tool has created significant global uncertainty. His administration announced hefty “Liberation Day” tariffs in April, setting a 10 percent baseline on imports from nearly all countries. While market turmoil and recession fears prompted a 90-day pause on some tariffs, the process remains subject to sudden changes. This unpredictable “start-pause tariff war,” or “Taco trade” (Trump always chickens out) as some analysts dubbed the pattern of announcing and then pausing tariffs, has unnerved investors. The goal of protecting domestic manufacturing could theoretically benefit from a weaker dollar, but retaliatory tariffs from other countries and the overall chaotic nature of the policy approach appear to negate this potential advantage and weigh heavily on the currency.
Rising National Debt and Fiscal Concerns
Another major factor cited is the worsening outlook for U.S. public debt. Reports indicate that a significant tax-cutting package championed by the Trump administration, potentially adding trillions of dollars to the national debt over the next decade, is fueling worries about the sustainability of U.S. government borrowings. This anticipated increase in the deficit is reportedly causing capital outflows from the U.S. Treasury market, further pressuring the dollar. The combination of trade proposals, inflation worries, and rising government debt creates a challenging environment for the currency.
Pressure on the Federal Reserve’s Independence
President Trump has repeatedly and publicly criticized Federal Reserve Chair Jerome Powell and the central bank’s monetary policy decisions. He has argued that current interest rates are too high and are harming the American economy. This persistent pressure and hints that he might seek a replacement for Powell who would prioritize lower borrowing costs have raised concerns about the Fed’s independence. Market expectations for more aggressive interest rate cuts by the Fed, partly fueled by this political pressure, also tend to weaken a currency as lower rates make dollar-denominated assets less attractive to foreign investors seeking yield.
Broader Market Reactions and Asset Shifts
The dollar’s decline hasn’t occurred in isolation; it has coincided with significant movements in other currency and asset markets. While the dollar struggled, some other major currencies saw notable gains.
The euro, for instance, rose significantly against the dollar, gaining 13 percent and trading above $1.17. This performance contradicted some earlier Wall Street forecasts that had predicted the euro might fall to parity with the dollar. Investors seemed to be focusing on growth risks within the U.S. economy and seeking safe assets elsewhere, such as German bonds. Gold also proved to be a strong safe-haven asset during this turbulent period, with its price jumping by 25 percent in the first half of the year as investors sought refuge outside the weakening dollar.
Equity markets experienced sharp swings influenced by tariff announcements and subsequent pauses. The S&P 500 index ultimately rallied to a record high by the end of June, driven partly by expectations of Fed rate cuts, FOMO (fear of missing out), strong earnings growth despite uncertainty, and optimism about AI. However, despite reaching records, the S&P 500’s 5 percent gain in the first half of 2025 lagged behind some European markets like the pan-European Stoxx 600 (+7%), the UK’s FTSE 100 (+7.2%), and Germany’s Dax (+20%) when compared in the same currency. This underperformance suggests a shift in relative investment appeal away from U.S. equities compared to some global peers.
Reassessing the Dollar’s Role
The combination of policy-induced uncertainty, rising debt, and questions surrounding monetary policy has led many investors to re-evaluate the dollar’s traditional safe-haven role. While its status as the world’s primary reserve currency is not under immediate threat, its appeal as a reliable refuge during market fluctuations has diminished for some. Investment analysts note that the period was defined by tariffs, economic forecast downgrades, and geopolitical conflict, leading to a “great big asset allocation reset.” This reset suggests that the U.S. is no longer the top choice for many investor portfolios.
For individuals, a weaker dollar means it’s more expensive for Americans to travel abroad. For foreigners, it makes investing in the United States less attractive, potentially sapping demand for U.S. assets when the government needs to borrow more money. On the flip side, a weaker dollar should theoretically help U.S. exporters by making their goods cheaper overseas, while making imports more expensive for U.S. consumers. However, these typical trade effects are currently complicated by the ongoing tariff threats and retaliatory measures.
While President Trump has backed down from some extreme tariff threats and U.S. stock and bond markets have recovered some earlier losses, the dollar has continued its downward trajectory. This sustained decline underscores the depth of investor concern regarding the structural implications of current economic policies and their impact on the dollar’s standing in the global financial system.
Frequently Asked Questions
Why did the US dollar see its worst start since 1973?
The US dollar’s sharp decline in the first half of 2025 is primarily attributed by analysts to a combination of President Trump’s economic policies. Key factors include the uncertainty and volatility of his trade policies and tariffs, concerns about the significant increase in U.S. national debt driven by proposed tax cuts, and perceived pressure on the independence of the Federal Reserve regarding interest rate decisions. This mix of policies has eroded investor confidence in the dollar’s traditional stability.
How have President Trump’s policies specifically impacted the dollar?
President Trump’s policies have impacted the dollar in several ways. His unpredictable “start-pause tariff war” has created global uncertainty, making the dollar less attractive as a safe haven. Proposed tax cuts adding trillions to the national debt raise concerns about fiscal sustainability, leading some investors to move away from U.S. assets. His public criticism of the Federal Reserve and calls for aggressive interest rate cuts also influence market expectations and can pressure the dollar downwards.
What were the broader effects of the dollar’s decline on other currencies and markets?
The dollar’s weakening has coincided with strength in other assets. The euro, for example, saw a significant 13% gain against the dollar. Gold also rose sharply, jumping 25%, as investors sought refuge. While the S&P 500 equity index reached record highs, driven partly by rate cut expectations and AI optimism, its performance lagged behind some European markets, indicating a potential shift in global investment preferences away from the U.S.
Conclusion
The U.S. dollar’s performance in the first half of 2025 represents a notable historical event, mirroring the scale of decline last seen during the major monetary system changes of 1973. Unlike that era’s structural shift away from gold, the current depreciation appears largely driven by policy choices and their perceived impact on the dollar’s stability and the U.S.’s standing in the global economy. The combination of trade policy uncertainty, rising debt concerns, and questions surrounding monetary policy independence has weighed heavily on the currency. While the dollar remains the world’s reserve currency, its recent trajectory highlights a significant challenge to its safe-haven appeal and suggests a potential resetting of global asset allocation strategies in response to the evolving economic and political landscape.
