USDJPY — rebound vs intervention: 154s, BoJ next week, Katayama still talking to Treasury

[LondonScalper]

USDJPY is the pair where people keep mixing up policy, MoF, and a bounce. They are three different trades.

Where we are (Fri 11 Sep)
Spot has been around the 154 handle into Europe after a violent yen week: from the ~160 area earlier toward a spike into the low 153s / high 152s mid-week, then a corrective bounce. Japan PPI still sticky (7.6% YoY in August). BoJ 17–18 Sep: a 25bp hike (talk of 1.25%, 31-year high) is largely priced; some chatter of a 50bp surprise is just that — chatter.

Intervention vs rebound
Japan already did the large one: reports of a record ~¥15.4tn between 30 Jul–26 Aug, with US participation and a joint statement. Finance Minister Katayama today: stance unchanged, keep close communication with US Treasury, “orderly markets.” Bessent’s recent warning to yen shorts is jawbone, not a fill.

A rebound in USDJPY after a 7–8 handle squeeze is what oversold carry looks like when USD catches a bid from US CPI/oil. That is not MoF buying dollars.

My split after 20 years on this pair
• Intervention: vertical, no pullback, often into Tokyo/London fix windows, newsflow lags. You don’t fade the first 80 pips.
• BoJ repricing: sticky, two-way, levels matter (152.80 / 154 / 156 type waypoints — your feed).
• USD rebound: follows US yields and DXY. Today’s core CPI 0.3% is that bid.

Desk rule: I do not buy USDJPY solely because “they intervened last month.” I also don’t short it solely because Katayama spoke. If I trade a bounce, it is against a defined Tokyo high/low with a time stop into the US cash open — not a view on the next MoF cheque.

Are you treating 154 as a BoJ-pause short, or as a USD-CPI bounce? Different stop.
