US closed Monday at highs and Asia opens with a green tape to chase, but the FX plumbing is the real story tonight.
The S&P and Dow closed at records Monday, with the Nasdaq leading, up about two percent, after Washington confirmed Iran talks resume and called off a planned strike, sending WTI down more than five percent. That relief trade is the tailwind Tokyo, Hong Kong and Shanghai open with — Nikkei and Hang Seng should gap higher tracking US futures and cheaper energy, and CSI 300 gets a similar lift as Beijing-linked risk premium comes off. The complication is USD/JPY: coordinated BOJ/Treasury intervention has pulled dollar-yen off a forty-year-low print near 164 to below 157, a five percent yen rally in three sessions, which is a headwind for exporters and a direct threat to the yen-funded carry trades that have been underwriting US tech longs. KOSPI is the tell — after a three-day aggregate slide near seventeen percent, an eighteen percent Friday snapback, and roughly a five percent whipsaw Monday, Samsung and SK Hynix are trading like a leveraged bet on Nasdaq semis, not a country index. USD/CNH stays comparatively boring, PBOC holding the fix steady while the yuan rides the broader dollar retreat.
Read-through to the US open: ISM Services lands Tuesday and Friday's July payrolls print looms after June's ugly 57k with steep downward revisions, so any soft beat gets read through a rate-cut lens rather than a growth-scare lens. Earnings flow (Palantir reaction, AMD and SpaceX Tuesday) sets single-name dispersion inside an index tape that wants to grind higher.
The risk: yen strength stops being orderly. A sharper BOJ follow-through or fresh jawboning that pushes USD/JPY through 155 fast enough to force carry unwinds flips this from a relief rally into a deleveraging event, and Korea's semis whipsaw is the fuse that would light it first.
