Japanese yen COT report
This page tracks speculative positioning in CME Japanese Yen futures: the latest net position, the weekly change, the long-short split and where the reading sits within stored history. Yen positioning is the market's running scorecard on the carry trade, and it has reversed violently before.

The contract: Japanese Yen futures (6J)
The 6J contract on the CME prices the yen in US dollars, and non-commercial positioning in it is the cleanest public window into the yen carry trade. For years the defining pattern was a large, persistent net short: speculators borrowed low-yielding yen to fund positions elsewhere, and the COT report showed it every week.
That structure makes yen positioning uniquely fragile. When the Bank of Japan shifts policy or global risk appetite breaks, the carry trade unwinds and the net position can swing by tens of thousands of contracts in a single week — moves that show up here before most commentary catches up.
What drives speculative yen positioning
Bank of Japan normalisation is the slow driver: every step away from ultra-loose policy shrinks the incentive to short the yen, and every hint of further tightening accelerates short covering. The fast driver is global risk sentiment — in risk-off episodes the yen's safe-haven role pulls speculators long regardless of the rate story.
US yields matter almost as much as Japanese ones. The carry trade's profitability depends on the US-Japan rate gap, so a fall in US yields can unwind yen shorts even when the Bank of Japan does nothing.
Reading 6J against USDJPY — the inversion
One mechanical point matters here: currency futures are quoted in US dollars per unit of the foreign currency. A net long position in this contract is therefore a bet on the foreign currency against the dollar — for pairs quoted the other way (USDJPY, USDCHF, USDCAD) a net long futures position means a bearish lean on the pair, and a net short position means a bullish lean. The table above applies that flip for you.
For GBPJPY the same logic applies through the yen leg: net long yen futures is a bearish lean on the cross, net short a bullish one. Combine this page with the pound page to see both sides of that trade.
How StraviaX uses yen positioning
Yen COT feeds the conviction layer on USDJPY and GBPJPY, with the inversion applied automatically. Given the carry trade's unwind risk, a crowded yen short read against the macro view is treated as a meaningful disagreement, and positioning never moves the headline score itself.
How StraviaX calculates this
The figures come from the CFTC Commitments of Traders report, non-commercial (speculative) positions in the listed futures contract. The data is as of Tuesday and published on Friday; this page shows both dates and flags the data as delayed when the latest report is more than ten days old.
The range position compares the current net position only with the history StraviaX has stored (since January 2026; gold since May 2026). It is labelled honestly — "within its range since January 2026" — and is never described as a one-year or three-year extreme until the stored history covers that span.
Inside StraviaX, COT positioning shapes the conviction label on a pair read. It never drives the headline macro score, which is built from rates, growth, inflation, spending, labour data and data surprises.
Frequently asked questions
What is the Japanese yen COT report?
The CFTC's weekly positioning data for CME Japanese Yen futures. This page shows the speculative net position, its weekly change and its place in stored history.
Does net long 6J mean bullish USDJPY?
No — the opposite. Yen futures are priced in dollars per yen, so net long 6J means speculators expect the yen to rise, which is a bearish lean on USDJPY. Net short 6J is a bullish USDJPY lean.
Why is yen positioning linked to the carry trade?
Low Japanese rates made borrowing yen to fund higher-yielding positions profitable for years. The net short in yen futures is that trade made visible, and its unwinding drives sharp yen rallies.
When is yen COT data released?
Every Friday, as of the previous Tuesday. The page shows both the report date and the release date, and flags the data if the latest report is more than ten days old.
