Despite facing persistent structural challenges, the US dollar has shown notable resilience against most major currencies in recent years. Analysts have identified several long-term pressures, including an overvalued real exchange rate, ongoing fiscal and trade deficits, and the gradual diversification of international reserves by foreign central banks. These factors have raised questions about the sustainability of the dollar’s strength over the long term. However, cyclical influences have played a key role in supporting the currency in the near term.

Exchange rates typically respond to shorter-term cyclical dynamics, with interest rate differentials considered among the most significant drivers of currency fluctuations. When interest rates in the United States rise relative to those in other advanced economies, dollar-denominated assets become more attractive, encouraging global capital inflows and bolstering demand for the currency. Historically, periods of elevated US interest rates tend to correlate with a stronger dollar.

Market expectations for the Federal Reserve’s policy have shifted markedly this year. Initial forecasts anticipated a 50 basis point reduction in rates during 2026, but persistent inflation, robust economic activity, and a more hawkish stance from Fed Chair Kevin Warsh have led to a reassessment. Currently, financial markets expect US policy rates to remain higher for a longer period, with the Federal Funds target range positioned at 3.50–3.75 percent. This contrasts with the European Central Bank’s deposit facility rate at 2.25 percent and the Bank of Japan’s policy rate at 1 percent, maintaining wide interest rate differentials favorable to the dollar.

Another important factor underpinning the dollar is the continued outperformance of the US stock market, driven largely by advances in artificial intelligence (AI) and technology sectors. The accelerating adoption of AI has spurred significant investment in digital infrastructure—such as semiconductors, data centers, cloud computing, and energy networks. As the global leader in AI innovation, the United States has attracted a disproportionate share of these investments, supporting strong corporate earnings and equity market gains. This dynamic has increased foreign demand for US financial assets, contributing further to the dollar’s strength.

Moreover, US economic growth continues to outperform that of other major advanced economies. Although growth has slowed from its recent peaks, key indicators such as the US composite Purchasing Managers’ Index (PMI) remain comfortably above the 50-point expansion level, signaling ongoing growth across both services and manufacturing sectors. By comparison, the Euro Area’s composite PMI has hovered near or below the stagnation threshold. The AI-driven investment boom is also boosting the US real economy through record levels of capital expenditure, which are expected to enhance productivity and long-term growth prospects.

In summary, while structural headwinds suggest a gradual depreciation of the US dollar over an extended horizon, cyclical factors remain the primary influence on its near-term performance. Elevated interest rates, strong foreign investment in US financial assets, and comparatively robust economic growth are likely to keep the dollar supported in the foreseeable future.
