The dominant macro driver overnight is the confirmed U.S.-Iran deal to end hostilities and reopen the Strait of Hormuz, announced by President Trump late Sunday and set for a formal signing ceremony in Switzerland on Friday. WTI crude fell 4.19% to $81.32/bbl and Brent dropped 4.24% to $83.63/bbl, their lowest levels since early March, unwinding the geopolitical risk premium that had been embedded in energy markets. Concurrently, gold surged 2.87% to $4,336/oz and the VIX fell 8.48% to 16.18, signalling a sharp rotation out of safe-haven positions and into risk assets — the S&P 500 closed up 1.65% at 7,554.29 and the Nasdaq added 3.07% to 26,683.94. The 2-year Treasury yield rose 7bp to 4.05%, reflecting persistent inflation expectations rather than growth enthusiasm, consistent with the FOMC two-day meeting commencing today under new Fed Chair Kevin Warsh.
For Asia-Pacific, the oil price collapse is a structural net positive for energy-import-dependent economies: Japan, South Korea, and China stand to benefit materially from reduced import bills. The Nikkei 225 rose 2.81% to 66,020.04 and the KOSPI surged 4.63% to 8,123.62, with South Korea's outsized gain reflecting its particular sensitivity to energy costs and semiconductor export momentum. USD/JPY has nudged higher to 160.34 — already at a psychologically sensitive level — as markets await the Bank of Japan rate decision today, chaired in Governor Ueda's absence by Deputy Governor Himino. The CNY firmed slightly with USD/CNY at 6.7565, reflecting both China trade data expectations and the oil-driven terms-of-trade improvement. Cross-asset pressure is most concentrated in Japanese yen positioning — CFTC data shows $10.1 billion in net short yen — where a dovish surprise from the BoJ could accelerate USD/JPY toward the ¥162 level.
