US Dollar Weakens Amid Global Policy Divergence as S&P 500 Surges 10% in April

Neutral (0.2)Impact: High

The US Dollar (USD) continued its downward correction in April, a trend that DBS Group Research economist Philip Wee expects to persist into May. This weakness follows a two-month rise in February and March and is attributed to diverging monetary policies: while the Federal Reserve is expected to maintain a prolonged pause through 2026, other major central banks such as the European Central Bank, Bank of England, and Reserve Bank of Australia are tightening policy. This divergence undermines the Dollar’s relative appeal, with the ECB and BoE warning against second-round inflation effects, providing structural support for the EUR and GBP against the USD. Additionally, the USD’s war-related haven appeal has diminished, further contributing to its decline [1].

In contrast, US equities experienced a dramatic rally in April, with the S&P 500 posting a 10% gain—the strongest monthly performance in 33 years. According to BNY’s Bob Savage, this surge reversed a prior defensive rotation from big tech into Energy, Materials, Industrials, and cash. The rally was catalyzed by the US–Iran ceasefire and signaled a shift from defensive cash positions to active investment, complicating Federal Reserve perceptions as financial conditions now play a larger role in shaping US demand. The cash-and-leverage dynamic is expected to test the bond-equity correlation going into May [2].

Savage notes that investors are now weighing several factors before deploying more cash in Q2: clarity on the war’s end, confidence in AI-driven growth, and a coherent understanding of energy-driven inflation. The transition from April to May is characterized by a debate between 'buying the dip' and 'chasing the tape,' with value and momentum factors clashing across global asset classes. As markets move into May, the main challenge will be reconciling easy financial conditions with elevated risk appetite, especially as central banks become more data-dependent and provide less forward guidance. Investors are increasingly focused on whether higher rates and sustained energy shocks will erode growth [2].

Overall, the combination of a weakening USD due to policy divergence and a robust equity rally highlights the complex interplay between monetary policy, sector rotation, and investor sentiment as markets enter the second quarter of 2024.

CONCLUSION

The US Dollar faces continued downward pressure as global central banks diverge from the Federal Reserve’s pause, while US equities rally sharply, complicating the Fed’s policy outlook. Investors are now focused on war clarity, AI-driven growth, and energy inflation as they consider further cash deployment. The coming months will test whether easy financial conditions can sustain risk appetite amid evolving central bank strategies.
