Last year marked a clear turning point in global currency markets. The US dollar lost more than 10% against the euro, a sharp reversal from its earlier dominance. This was not a flash move driven by panic, but a slow, persistent repricing of macro realities. The big question now is simple: was that a one-off adjustment, or the start of a longer trend that could repeat in 2026? Why the Dollar Fell Last Year The dollar’s weakness was fundamentally policy-driven, not crisis-driven. First, the interest-rate advantage of the US narrowed sharply. Markets began pricing in a Federal Reserve that had reached the peak of its tightening cycle and was shifting toward easing. As yield differentials compressed, the incentive to park capital in dollar assets diminished. Second, Europe surprised on resilience. Growth did not collapse as feared, energy shock risks faded, and capital began flowing back into euro-denominated assets. The euro benefited not from exceptional strength, but from expectations becoming less pessimistic. Third, the dollar faced structural fatigue. Large fiscal deficits, rising debt issuance, and growing political uncertainty weakened the “one-way long USD” trade that had dominated earlier years. The result was a broad, orderly depreciation—enough to erase more than a decade of perceived dollar invincibility. Will 2026 See a Repeat? A carbon copy decline of another 10% is possible, but not guaranteed. The conditions that weakened the dollar are still present, but less powerful. The Fed may continue easing, but the pace is expected to be gradual. The ECB is also cutting rates, which limits how much further interest-rate divergence can move against the dollar.
That said, the structural forces still lean against sustained dollar strength: US twin deficits remain large. Global investors are increasingly diversifying away from dollar concentration. The euro no longer carries the existential risk premium it once did. Last but not least the geopolitics of Trump has started hurting badly. This suggests that the dollar may remain under pressure, but the move is more likely to be incremental rather than dramatic. What Could Change the Narrative A repeat of last year’s sharp fall would require one of three things: Faster-than-expected US rate cuts. A meaningful slowdown in US growth. A global risk-on environment that reduces demand for dollar safety. Conversely, any renewed geopolitical maturity or US growth outperformance (looks unlikely) could stabilise or even strengthen the dollar. Bottom Line Last year’s double-digit USD decline against the euro was a re-pricing, not a collapse. In 2026, the base case is continued dollar softness, not a free fall. The era of automatic dollar dominance is fading—but it is not over yet. Currency markets rarely repeat exactly. They evolve—often in quieter, more expensive ways for those unprepared.
