In a recent paper1, we argued that sustained weakness in the US dollar would require clear evidence of narrowing real interest rate or growth differentials between the US and its major trading partners—conditions that have yet to fully materialise. Since then, the narrative around the weak dollar has continued to gain traction, but much of the perceived dollar weakness is actually a reflection of euro strength, which may now be overextended. Meanwhile, the US economy continues to demonstrate resilience, interest rate differentials remain supportive, and the dollar’s risk premium might be higher than warranted by underlying risks. Taken together, these factors might suggest a more constructive outlook for the dollar than current market sentiment implies.
The dollar index predominantly reflects euro strength, which now may be overextended
The narrative of a weakening dollar often overlooks the fact that much of the recent movement in currency markets has been driven by euro appreciation. Broader dollar indices, which include emerging market currencies, have only declined modestly from their peaks2.
Some of the appreciation in the euro seems justified given that Germany’s recent approval of fiscal spending marks a significant shift in its traditionally conservative fiscal stance. The key question now is whether this spending will translate into productive investment that enhances the country’s supply-side capacity, or whether it will be constrained by structural bottlenecks.
Germany continues to face challenges such as labour shortages and bureaucratic inefficiencies, which could limit the effectiveness of the stimulus. If these constraints persist, the risk is that the additional spending may fuel inflation rather than drive real economic expansion. Furthermore, by front-loading a substantial portion of the spending, policymakers may reduce the urgency or political will to pursue more difficult and unpopular structural reforms.
At this stage, it remains too early to determine the outcome with confidence. What is evident, however, is that the euro’s recent strength appears increasingly out of step with underlying economic fundamentals. As noted in our earlier paper3, the euro area is still expected to only grow around 1% in 2025, with Germany nearing stagnation4—levels that would typically not support sustained euro appreciation.
Current level of the dollar suggests lower US real rates
The dollar’s performance is closely tied to cyclical factors including growth and real interest rates. The two are connected as interest rate differentials between countries generally reflect a difference in growth and inflation between economies, with stronger growth generally leading to higher interest rates.
