FX hedging drove US dollar weakness in April 2025
Currency hedging by non-US investors significantly contributed to the US dollar's weakness in April and May 2025. This activity, particularly from Asian investors, aimed to mitigate losses on unhedged dollar asset exposures.
Hedging, not confidence, drove dollar's fall
In April 2025, US securities markets experienced a "triple decline" with equities, bonds, and the US dollar falling in unison.
This unusual dollar depreciation during a risk-off episode initially prompted commentary about a broad loss of confidence in dollar assets.
However, evidence suggests that the slide was more plausibly explained by hedging activity of non-US investors.
These investors, holding significant unhedged dollar exposures, increased foreign exchange (FX) swap and forward overlays to reduce currency risk.
The largest dollar declines occurred during Asian trading hours, indicating a substantial role for Asian investors.
Non-US investors hold a large share of dollar bonds, particularly from Asia and Europe, which further underscores their potential impact on currency movements.
Hedging costs and the dollar's allure
Non-US investors reduced currency hedging in recent years, influenced by high costs and a strong US dollar.
Hedging became more expensive after the Federal Reserve's 2022 rate hiking cycle, elevating short-term dollar interest rates, especially for Asian and European currencies.
A bullish dollar trend from 2021 to 2024 also encouraged investors to keep portfolios unhedged, seeking currency gains.
When the dollar depreciated in April 2025, these investors faced losses on unhedged positions.
This triggered an ex post increase in hedge ratios, amplifying the dollar's downward pressure to mitigate further losses.
A nuanced view of dollar dynamics
The study offers a crucial reinterpretation of the dollar's recent volatility, shifting focus from broad confidence issues to specific market mechanics.
While not the sole factor, ex post hedging appears to have been a primary driver, particularly among Asian investors.
This nuanced perspective is vital for understanding currency movements beyond simple sentiment indicators.
