EUR/USD Correlation Shift Impacts US Assets, Hedging Strategies
Updated June 26, 2025
A key correlation between the euro and the U.S.dollar (EUR/USD) and the S&P 500 (SPX) is undergoing a shift, perhaps triggering notable hedging activity and impacting U.S. assets. For large asset allocators, especially non-U.S. pension funds, the relationship between currency fluctuations and asset values is critical.
Historically,the 120-day rolling correlation between EUR/USD and SPX has been largely positive for the past two decades. This meant that a decline in the SPX was typically accompanied by a weakening euro. Consequently,hedging EUR/USD risk associated with U.S. asset purchases proved ineffective, as the euro exposure acted as a hedge during risk-off periods for U.S. stock markets.
However,there have been exceptions to this trend,including:
- The early phase of the 2008 global financial crisis.
- the european Central Bank’s (ECB) quantitative easing (QE) announcements in 2015-2016.
- Summer 2019, when German Bund yields reached -0.75%.
These breaks in correlation proved temporary, requiring significant macro events to occur. The correlation quickly reverted to its “normal” state. Now, foreign asset managers find themselves under-hedged, maintaining substantial long USD positions just as correlations are beginning to break again.
This situation could necessitate multi-trillion dollar hedging flows, leading to a substantial sale of U.S. dollars in the market. Investors are closely monitoring the potential for a weakening USD trend.
What’s next
The potential for a weakening U.S. dollar is being closely watched by investors, as a shift in EUR/USD correlation could trigger multi-trillion dollar hedging flows, impacting US assets and requiring a re-evaluation of hedging strategies.
