For several months now, the U.S. dollar has been on a steady downward trend in global financial markets. While it may seem intuitive to blame the Federal Reserve’s monetary policy, a closer look suggests that the real driver behind the weakening dollar lies not in the central bank’s actions, but in the political decisions coming out of the White House.
From Strength to Uncertainty: A Shift Since Fall 2024
As recently as autumn 2024, the outlook for the dollar was remarkably different. The increasing likelihood of Donald Trump’s re-election triggered a surge in the U.S. currency. Markets expected that new tariffs introduced by his administration would drive up consumer prices, prompting the Fed to maintain its hawkish stance, especially with the real economy still showing strength. The result? The U.S. Dollar Index rose by 9% in just a few months — a classic case of higher inflation expectations translating into higher rates and, consequently, a stronger currency.
February 2025: A Turning Point
Things started to change at the end of February 2025. By March, the market narrative began to shift toward concerns that Trump’s tariffs might not only stoke inflation but also harm real economic growth, raising the specter of stagflation. In such a scenario, the Fed would be forced to balance inflation control with maintaining employment, potentially curbing its ability to tighten monetary policy further.
At the same time, Trump’s public attacks on the Fed’s independence began to erode investor confidence in the predictability of U.S. central bank policy.
Macro Data Paints a Mixed Picture
Despite the narrative shift, the macroeconomic data has not yet fully confirmed an economic slowdown. The weak GDP growth in Q1 2025 was largely due to one-off import distortions. Meanwhile, the labor market remains resilient, and consumer spending is holding up despite mounting uncertainty. Recognizing this, the Fed continues to maintain its hawkish tone, signaling alertness to inflation risks.
Yet markets have stopped rewarding the dollar for this stance.
The Disconnect Between Rates and the Dollar
Since early March, the traditional correlation between interest rate expectations and the EUR/USD exchange rate has weakened. This is evident in the divergence between the currency pair and the U.S.-German 2-year bond yield spread, as well as expectations for the June Fed meeting rate. Put simply: the dollar is weakening even though U.S. rates remain higher than those in Europe.
A similar disconnect can be seen in the relationship between rising short-term inflation expectations and the dollar’s performance. Typically, higher inflation forecasts lead to higher interest rates and a stronger currency. Instead, the dollar has weakened, suggesting that markets view the inflationary spike as transitory, driven mainly by tariff-related price shocks. In such a scenario, the Fed is unlikely to react aggressively, and the market reprices the dollar downward to reflect diminished purchasing power.
It’s the Politics, Not the Policy
The dollar’s current weakness does not stem from Fed policy, but rather from a broad range of political actions by President Trump. Beyond inflation fears related to tariffs, investors are rattled by proposals for a tax on foreign investments, concerns over fiscal instability, and what many perceive as chaotic economic governance.
This macroeconomic and institutional uncertainty is discouraging global capital from holding dollar positions, even though monetary fundamentals would theoretically support the currency.
Conclusion: The dollar’s decline in 2025 reflects a shift in how markets assess risk. No longer driven solely by interest rate expectations or Fed policy, the greenback’s trajectory is now more sensitive to political volatility and credibility. As long as uncertainty surrounds fiscal plans, trade policy, and central bank independence, the dollar may struggle to regain its former strength — regardless of where interest rates stand.
