Currency Hedging‘s Role in Recent dollar Weakness Examined by BIS
Table of Contents
A recent report by the Bank for International Settlements (BIS) analyzes the role of currency hedgers in the dollar’s depreciation observed during April and May 2025, identifying the geographical origins of this hedging activity. The study investigates whether hedging activity contributed to the dollar’s unusual decline amidst a broader “risk-off” market environment, characterized by simultaneous drops in equities and bonds.
BIS Highlights Currency Hedging’s Impact on Dollar’s Spring Decline
The BIS report, authored by Hyun Song Shin, Philip Wooldridge, and Dora xia, challenges initial explanations attributing the dollar’s weakness to a loss of confidence in U.S.assets or a diminished global role. Rather, the authors propose that increased currency hedging by non-U.S. investors offers a more compelling clarification. This hedging activity emerged after a prolonged period of dollar strength, during which many investors refrained from hedging their dollar exposures.
Did You Know? The dollar’s trade-weighted index, which measures its value against a basket of other currencies, experienced a notable decline in April and may 2025, prompting the BIS examination.
Specifically, the report notes that while non-U.S. investors maintained their holdings of dollar-denominated assets during the market downturn, they began implementing FX swap and forward overlays to hedge their currency risk. the most significant declines in the dollar’s value occurred during Asian trading hours, suggesting that investors in that region were particularly active in hedging their dollar exposures.
Shifting Investor Strategies and the Rise of Ex-Post Hedging
Historically low hedge ratios, driven by high hedging costs and a persistent bullish outlook on the dollar, characterized investor behavior in recent years.For instance, Japanese life insurers had reduced their hedge ratios from 60% to 40%. However, the dollar’s decline in April spurred a shift towards “ex-post” hedging, where investors sold currencies after purchasing dollar-denominated bonds, indicating a reactive approach to managing currency risk.
Pro Tip: Monitoring cross-currency basis swaps can provide insights into hedging demand and potential market vulnerabilities.
Data cited in the report reveals that changes in the cross-currency basis between March and April/May 2025 align with increased demand for hedging dollar investments. The basis against the U.S. dollar declined for several Asian currencies and the euro,indicating that hedging dollar exposures through the FX swap market became more expensive due to heightened demand.
intraday Analysis Confirms Asian Investors’ Role
The BIS authors observed that intraday movements in the dollar and bond prices suggest that hedging by Asian investors played a significant role in the dollar’s decline during Asian trading hours. While the dollar depreciated, U.S.Treasury securities experienced gains, indicating that the dollar’s weakness was not correlated with widespread selling of U.S.assets, at least not in government bonds.
| Region | Impact on Dollar Weakness (April-May 2025) | Hedging Strategy |
|---|---|---|
| Asia | Significant role, particularly during Asian trading hours | Increased FX swap and forward overlays |
| Europe | Reduced hedge ratios prior to April, potentially contributing to initial weakness | Shift towards ex-post hedging in April |
Future Outlook: Hedging’s Diminishing Role?
Looking ahead, the BIS report suggests that the importance of hedging as a driver of exchange rates may diminish as the U.S. economic outlook, influenced by higher tariffs, exerts a greater influence.Discussions regarding strategic allocations to U.S. assets will also play a crucial role in shaping future exchange rate dynamics.
However, the authors caution that even after ex-post hedging subsides, monitoring FX hedge ratios and investors’ currency exposure management remains essential. The over-the-counter nature of FX swap markets and the diverse range of participants make it challenging to track the accumulation of vulnerabilities, such as concentrated unhedged FX positions.
Furthermore, higher hedge ratios tend to be associated with higher maturity mismatches, as hedging instruments typically have shorter maturities than the underlying assets. This maturity mismatch exposes hedged investors to potential stress in dollar funding markets and rollover risks, particularly during periods of market dysfunction, as witnessed during the COVID-19 crisis and the Global Financial Crisis (GFC), which often necessitate central bank intervention.
Evergreen Insights: Understanding Currency Hedging
Currency hedging is a risk management strategy used by investors and businesses to protect themselves from potential losses due to fluctuations in exchange rates.By using financial instruments like FX swaps and forward contracts, entities can lock in a specific exchange rate for future transactions, mitigating the uncertainty associated with currency movements.
The effectiveness of currency hedging depends on various factors, including the accuracy of exchange rate forecasts, the cost of hedging instruments, and the overall market environment.While hedging can provide protection against adverse currency movements, it also limits the potential for gains if the exchange rate moves in a favorable direction.
