⚡ Institutional FX Volumes Slipped in July as Two Yen Intervention Days Carried the Month

Institutional foreign exchange volumes declined across major trading venues in July, with average daily volumes falling between 1.2% and 7.8% compared to June, according to data from FXSpotStream, Cboe FX, 360T, and Euronext FX. Despite the monthly decline, all four platforms traded substantially above year-ago levels. The month’s activity was heavily concentrated on July 30 and 31, when Japan’s Ministry of Finance and the US Treasury executed coordinated yen purchases in their first joint intervention since 2011.

FXSpotStream posted the smallest drop at 1.2% to $158.11 billion daily, while remaining 51.7% above July 2025. Cboe FX fell 4.8% to $56.79 billion, 360T declined 4.7% to $40.39 billion, and Euronext FX dropped 7.8% to $28.16 billion. Excluding the intervention days, July volumes would have been notably weaker. Euronext FX’s two intervention sessions alone accounted for 16.6% of monthly volume.

FXnCO Insight

Traders should anticipate heightened volatility and liquidity concentration around central bank intervention events, which can reshape monthly volume patterns and create significant intraday opportunities.
