USD/JPY broke above 162 Tuesday, the weakest the yen’s been since December 1986. Hit highs near 162.40. Japanese officials tried talking it down first. Didn’t matter. Traders ran straight through the warnings.

Chief Cabinet Secretary Kihara said beforehand Japan stands ready to act. Finance Minister Katayama repeated they’ll respond appropriately and could be decisive. Those were telegraphed interventions. Market got the message and ignored it.

That’s the biggest red flag for Japanese authorities. Verbal warnings that once moved markets now get ignored. People either stopped believing intervention threats or they calculated the BOJ won’t actually step in hard enough to matter. Probably both.

The yen recovering little ground after Katayama’s comments confirms traders think it’s bluffing. If they thought intervention was coming, they’d cover shorts immediately. Instead they sat holding losing positions, betting authorities won’t follow through.

China’s PMI data came in hot. Manufacturing back in expansion at 50.3 versus 50.1 expected. Services PMI beat at 50.2 versus 49.9. Composite hit 50.6. But almost all the strength came from AI-linked tech exports. Domestic demand stayed weak. That divergence matters because it means growth isn’t broad-based.

PBOC doubled its overnight reverse repo to 600 billion yuan. Trying to keep funding cheap through month-end. Rates stayed at 1.25%, 15 basis points below the main policy rate. The signal is clear: central bank wants to keep money loose despite stronger exports.

Australia’s RBA minutes showed the board holding but clearly ready to hike again if needed. They’re still seeing excess demand in the economy, which justifies staying restrictive. Australia’s got high inflation relative to developed peers, so rate hikes might continue.

Oil stayed rangebound all day. No help there for the yen since weaker commodity prices don’t strengthen the currency. Gold slipped below $4,000. Nikkei managed to rise nearly 1% despite or maybe because of yen weakness – helps exporters.

Hong Kong and mainland Chinese stocks both fell despite decent PMI data. That’s telling. Good economic news isn’t translating to equity demand right now.

The real question is whether 162 becomes a new trading level or if it finally breaks Japanese patience enough to trigger actual intervention. One press conference from a new BOJ board member coming Tuesday at 5pm Tokyo time. That could shift sentiment if the message turns hawkish on rates and the currency.
