Click365 USD/JPY volume rebounds in September 2026 as open interest falls
Click365 USD/JPY trading volume rose to 547,325 contracts in September 2026, while month-end open interest fell to 337,645. Volume was the highest and open interest the lowest in the March–September window.
USD/JPY monthly trading volume on Tokyo Financial Exchange’s Click365 venue rose to 547,325 contracts in September 2026, while month-end open interest declined to 337,645 contracts. The exchange’s figures show a rebound in trading activity alongside a smaller stock of outstanding positions, rather than a simultaneous expansion in both measures.
August volume had been 376,532 contracts. September’s recovery put activity above July’s 515,253 contracts and made it the strongest month in the March–September reporting window. That comparison gives the rebound more significance than a recovery from August alone: September also exceeded the earlier March and April readings. Nevertheless, the intervening declines in May, June and August show that the seven-month record was uneven, not a sustained monthly climb.
Open interest moved in the opposite direction. It fell from 347,485 contracts at the end of August to the lowest month-end reading in the same seven-month window. Outstanding contracts had peaked within that period at 370,561 in June, then declined in July, August and September. The latest fall therefore extended an existing contraction in positions even as monthly trading volume recovered.
The divergence is the central signal for this contract series. More contracts traded during September, but fewer remained outstanding at month-end. This supports a distinction between transaction activity and the stock of positions; it does not establish why participants traded or whether liquidity improved. A higher monthly flow alone is insufficient evidence of a broader expansion in participation.
TRY-JPY leads the selected contract series
Among the eight selected standard-size currency-pair series, TRY-JPY recorded the largest September volume at 871,264 contracts, ahead of USD-JPY. MXN-JPY followed at 230,985 contracts. ZAR-JPY and HUF-JPY also each exceeded 100,000 contracts, while AUD-JPY, NZD-JPY and GBP-JPY recorded smaller volumes.
These rankings describe separate Click365 contract series, not the entire Japanese FX market. LARGE variants are separately specified and excluded from the selection. The figures are contract counts, not yen-denominated notional turnover, so the selected-pair comparison describes activity within this venue rather than a market-wide monetary total.
