[MARKET ANALYSIS] JPY rallies against all G10 peers, most pronounced against USD into payrolls on Friday

• Further Yen strength which has led to the Buck underperforming against all G10 peers.
• JPY sees outperformance vs USD with the pair halted just short of 156.00 from a peak above 160 on Wednesday. The move comes absent of a headline driver, but there are several factors which weigh on the pair at the moment. Some suggest potential intervention/rate checks, however price action is more gradual, therefore not consistent with previous bouts, while others say the GPIF’s meeting has fuelled speculation it may raise domestic allocation targets. Other factors which have weighed in the past weeks are the clearer US influence on Japanese policy after Bessent met with various Japanese officials, this hawkish intent also evident in Ueda and Takata's remarks, the latter more so. This morning however, Bloomberg sources said the BoJ is set to favour a 25bps hike and a "flexible" future pace in policy; a report which sparked a dead cat bounce in USD/JPY which lifted back above 157.00.
• DXY (-0.3%) is being driven by JPY moves today with the index falling to a 99.16 trough before paring some of the move after the aforementioned Bloomberg sources. Eyes are on the Payrolls print due on Friday, albeit which has less relevance than typical given the Fed's keen eye on inflation impacts from the Middle East conflict.
• CHF is the second best performer, weaker only against JPY after hotter than expected GDP and CPI data. Following the inflation print, USD/CHF moved lower by 15 pips within a minute then extended the move to c. 25 pips within ten minutes at a 0.8083 low following the release. GDP also indicated a hot Swiss economy in Q2, albeit caveated by the chemical and pharma metrics which surged +10.5% during the period.

Broad yen strength without a clean catalyst is the classic signature that separates intervention speculation from genuine repositioning: actual Ministry of Finance episodes have historically produced sharp, vertical moves of several big figures in minutes, whereas the gradual grind described here is more consistent with flow-driven repricing. Rate checks, where officials call dealers for quotes, have on past occasions served as the warning shot and tend to slow rather than reverse a trend, with sustained turns usually requiring the policy backdrop to shift alongside. The GPIF angle is a recurring pre-meeting pattern: speculation around higher domestic allocation targets has periodically supported the yen, though historically the actual reviews have moved at a glacial pace and rarely justified the anticipation. The central tension is between hawkish BoJ signalling, amplified here by reported US tolerance for a firmer yen, and the sourced report of a single 25bp step with flexible pacing, which has in past cycles been read as commitment-light and has tended to fade initial yen gains. The transmission runs through US-Japan rate differentials at the front end, so the payrolls print matters mainly insofar as it shifts that spread, and the notes' own caveat that the Fed is watching Middle East inflation pass-through cuts both ways for the dollar. Worth watching is whether price action accelerates into the kind of one-way move that has previously drawn actual intervention, and whether Japanese jawboning escalates from rate checks to explicit commentary.
