The FX volatility drought rolls on. Implied volatility across G10 FX continues to grind lower, with most pairs at or near pre-Middle East conflict lows as realised volatility stays stubbornly absent. The market remains hopeful of an Iran/US deal, and that cautious optimism continues to reward short vol positions.

USD/JPY is the standout. Sub 3-month implied volatility has broken below the late April pre-intervention lows to fresh 4-year lows, with spot pinned near 159.00. But there's a twist — the gamma wall that has helped contain spot may be about to crumble. A significant chunk of exotic option positions, including barriers and triggers at and above 160.00, are set to expire over the coming week, potentially loosening USD/JPY's shackles. The one event keeping traders honest is June 3, when BoJ Governor Ueda speaks ahead of the June 16 rate decision — post June 3 expiries have been attracting buyers.

EUR/USD 1-month expiry implied volatility at 5.3 is the lowest since January, when it based at 5.0, with multi-year lows from December 2024 sitting in the mid-4s. Risk reversals retain a marginal downside bias at just 0.3 — a shadow of the 1.5 premium seen in early March when the oil spike sharpened EUR downside fears. Directional conviction is thin, but some banks are warning about the risk of a short term USD recovery.

AUD/USD offers the most interesting opportunity. One-month expiry implied vol spiked from 7.7 to 8.8 last week as spot sold off, and is slowly reverting to 8.2. Any further reversion could represent good value for those seeking a hedge against renewed risk-off episodes such as a breakdown in Iran/US talks.

The broader message is clear: without a fresh volatility catalyst, FX option implied volatility looks set to stay lower for longer. The vacuum holds — for now.
