FX Options Insights 08/04/25

Volatility in the FX market has eased as risk experiences a slight rebound, allowing option implied volatility to decrease from its recent and long-term highs across most currency pairs. Nonetheless, despite these developments, implied volatility continues to be significantly higher than levels observed prior to the tariff announcement, indicating a market still cautious of further unfavorable currency fluctuations.

After some initial declines following the tariff news, the USD has gained momentum this week as safe-haven appeal outweighed concerns about U.S. stagflation. This recovery is particularly observable in EUR/USD option risk reversals, where the premium for topside volatility over downside volatility surged to its highest point since 2020 post-announcement but has since normalized to a neutral position, showing no premium in either direction.

Currencies closely linked to risk such as AUD/USD have also experienced a decline in implied volatilities. After achieving the largest increases among G10 FX counterparts, the benchmark 1-month expiry AUD/USD implied volatility has decreased to 15.0 from 17.0, although it was at 8.5 before the tariff announcement. Its downside strike risk reversal premiums have been more hesitant in relinquishing recent gains.

Furthermore, USD/CNH has also seen a reduction in its implied volatility from Monday's peaks, but at 6.7 compared to 7.5, the 1-month expiry remains relatively high when contrasted with last week's lows of 4.6. Risk reversals maintain a strong premium for the topside over downside strikes for USD/CNH.
