The dominant macro driver overnight was a sharp escalation in Middle East geopolitical risk, with intensified Iranian and Houthi attacks on shipping in the Persian Gulf and Strait of Hormuz — including strikes on Saudi airports — sending Brent crude surging 3.25% to USD 103.46/bbl and WTI up 2.83% to USD 90.78/bbl. This supply-disruption premium compounds an already hostile rates environment: the US 10-year Treasury yield rose 1bp to 5.28% while the 30-year climbed 3bp to 5.67%, levels that signal markets are pricing a sustained restrictive Fed stance well into 2027. September FOMC minutes confirmed unanimous support for the prior 25bp hike and indicated most participants viewed another increase as likely appropriate by year-end, with Fed Governor Waller reinforcing that view explicitly.
For Asia-Pacific, the pressure is concentrated in two intersecting channels. Japan, as a net energy importer, faces intensified cost pressures from elevated crude — the Nikkei VIX surged 12.09% to 32.73, reflecting acute near-term uncertainty, while the Nikkei 225 closed down 0.92% to 70,035.71 and TOPIX banks fell 1.90% as the sector faces a dual headwind of higher import costs and global rate volatility. The JPY at 157.91 per USD (down only 0.09%) offers limited buffer; the PBOC's firmer yuan fix — USD/CNY at 6.6938, down 0.16% — signals Beijing's preference for currency stability rather than depreciation, even as post-Golden Week consumption data disappointed and the SSE managed only a marginal 0.31% gain. Cross-asset pressure is most acute in Korea, where the KOSPI fell 1.98% to 6,803.9 and the KRW weakened 0.25% to 1,342.49 per USD, reflecting the combined drag of high US yields, oil-driven inflation risk, and semiconductor sector uncertainty.
