[MARKET ANALYSIS] JPY underperforms after yesterday’s suspected intervention and following a relatively uneventful BoJ
- JPY has been in focus following yesterday’s mammoth gains, which sparked intervention speculation. Nikkei sources yesterday said Japan's government and BoJ intervened in the FX market yesterday by buying yen and selling dollars, while desks conducted rate checks. Furthermore, US Treasury Secretary Bessent said the yen has substantially overshot equilibrium, and the US views excess yen volatility as unhealthy, while he added that the yen is very undervalued and that Japan may have intervened in currency markets on Thursday. Add to that, the BoJ kept rates unchanged at 1.00%, which was widely expected as the central bank had just hiked rates at the last meeting in June, while the decision was made by an 8-1 vote, with board member Takata the dissenter who proposed a 25bps rate hike, but the proposal was turned down by a majority vote. There was little deviation in the language from the central bank, while in terms of the Outlook Report, Real GDP forecasts for FY26 and FY27 were slightly raised, and the Core CPI estimate was lowered for FY26 but raised for FY27. Governor Ueda’s presser prompted some modest moves in the JPY, but the pair returned to pre-presser levels towards the end. Notably, some JPY gains were seen after Ueda said the next meeting will keep in mind the risk of inflation overshooting more than in the past, with brief action also seen after Ueda said the Bank does not need to wait for data showing inflation has completely stabilised at 2% before making policy decisions. USD/JPY resides around the middle of a current 159.37-160.88 range, back above its 100 DMA at 160.06, after printing a mammoth range on Thursday between 157.48-163.74.
- DYX posts modest intraday gains after being pushed lower by the JPY on Thursday, albeit upside is capped by softer crude oil prices. Fresh newsflow for the Dollar has been light this morning, with focus on the BoJ. Analysts at ING suggest that “leveraged funds reported their largest EUR/USD short positions since 2021. That suggests there may still be room for further USD long-squeezing, and we remain reluctant to call the bottom in this dollar selloff just yet.“ DXY trades in a 100.02-100.25 range at the time of writing, vs yesterday’s 99.86-101.07 range.
- EUR is subdued after gaining yesterday on the JPY-induced Dollar decline. EUR/USD resides towards the bottom of a 1.1504-1.1531 range vs yesterday’s rise to 1.1537 from 1.1434. No move was seen on the hotter-than-expected French prelim CPI, higher-than-expected German unemployment rate, or increase in Italian business and consumer confidence. EUR/JPY found resistance near its 100 DMA (185.18) before waning back closer to 184. GBP is similarly subdued vs the USD within 1.3435-1.3471 after hitting a 1.3477 peak yesterday amid the JPY-induced dollar weakness. UK specifics have been light this morning.
- Antipodeans are flat/mixed with little traction seen from the overall risk appetite across the market, and with metals also showing no clear direction. Overnight, China's official PMIs unexpectedly fell into contractionary territory in July. The weaker-than-expected data reinforced concerns about the pace of China's economic recovery following the Politburo meeting, where Beijing signalled it would continue implementing existing support measures rather than introduce large-scale stimulus. Antipodeans were little moved, with AUD/NZD holding a relatively narrow range between 1.1949 and 1.1985.
Suspected yen-buying intervention after a sharp USD/JPY run higher fits a well-worn pattern: authorities tend to act into one-way, fast moves rather than at fixed levels, and the initial kneejerk typically gives way to a test of resolve as the pair gravitates back toward the pre-intervention zone unless accompanied by a policy shift. The historical sequence to note is rate checks first, actual operations second, then jawboning, with effectiveness historically greater when US counterparts voice discomfort with dollar strength, as the Treasury Secretary's comments here do; coordinated or US-tolerated episodes have tended to stick better than unilateral ones. The BoJ side of the story cuts the other way: a hold with a lone dissenter pushing for a hike, guidance flagging tolerance for acting before inflation fully stabilises, and an upward FY27 core CPI revision all keep the hiking bias alive, which is the fundamental channel through which intervention eventually gains durability. The case distinction worth drawing is between intervention into an unchanged policy backdrop, which has historically bought time rather than turned trends, and intervention front-running a tightening cycle, where follow-through has been more durable. Watch the pace of any re-approach toward the intervention zone, further official commentary on both sides, and whether upcoming wage and CPI prints give the hawks on the board more company than Takata. Cross-yen pairs such as EUR/JPY at technical levels tend to shadow USD/JPY in these episodes rather than trade on their own specifics.
