Institutional FX volumes fell across the four largest venues in July, but two days of coordinated dollar-yen intervention by Japan and the United States masked a sharper underlying slowdown. On Tokyo's retail futures exchange, the Turkish lira carry trade — not the yen — drove the month's growth, while the Bank of Japan's July meeting notes showed board members leaning toward faster rate hikes.
Institutional foreign-exchange volumes fell across the world's four largest venues in July, and the drop would look sharper still without two days of coordinated dollar-yen intervention that padded the month's totals.
Japan's Ministry of Finance bought yen on July 30, and the US Treasury joined the operation the following day — the first coordinated intervention between the two governments since 2011, both said on August 3. Treasury Secretary Scott Bessent said: "We will not hesitate to participate in further joint intervention."
Two Days Papered Over a Broader Slowdown
Average daily volume fell between 1.2% and 7.8% from June at FXSpotStream, Cboe FX, 360T and Euronext FX, though all four venues still traded well above their year-earlier levels. FXSpotStream posted the smallest decline, at $158.11 billion a day, down 1.2% from June and 51.7% above July 2025. Cboe FX's single-counted volume fell 4.8% to $56.79 billion a day.
Euronext FX averaged $25.73 billion over July's other 21 sessions, just 1.2% above its year-ago pace. But July 30 and 31 alone brought in $107.33 billion, or 16.6% of the month's volume from just 8.7% of its sessions, lifting the full-month average to $28.16 billion. 360T's spot volume fell 4.7% to $40.39 billion a day; stripping out the same two sessions drops its average to $38.59 billion.
Turkish Lira Carry Trade Outpaces the Yen in Tokyo
Tokyo Financial Exchange's Click 365 FX futures volume jumped 43.1% from June to 2,634,199 contracts, up 86.6% from a year earlier. Yet it was the lira, not the yen, driving the gain: TRY/JPY volume rose 62.8% from June to 1,142,584 contracts, 43.4% of the exchange's total and 460.6% above July 2025. Dollar-yen volume climbed 103.1% on the month to 515,253 contracts, still less than half the lira pair's total, extending a shift that began in June, when TRY/JPY first overtook it.
Bank of Japan's Hawkish Tilt Adds to the Yen's Case
The Bank of Japan's Summary of Opinions from its July meeting showed board members increasingly weighing tighter policy, MQL5 reported, citing concern over inflation risk and discussion of a faster pace of rate hikes. Friday's weak US jobs data trimmed the odds of another Federal Reserve rate move, MQL5 said, narrowing the policy gap between the two central banks just as the BOJ's own board turns more hawkish.
