The Federal Reserve delivered a 25 basis point rate hike on September 16, lifting the federal funds target range to 3.75–4.00% — its first hike since 2023 — with Chair Kevin Warsh citing sticky inflation and a strengthening economy and signalling the possibility of further tightening later in 2026. The US 10-year Treasury yield has now reached 5.00%, a level last seen in 2007, with the 2-year at 4.67% and the 30-year at 5.36%, pricing that reflects markets taking seriously the prospect of a sustained higher-for-longer regime rather than a one-and-done adjustment. Crude oil remains a compounding inflation input, with Brent at USD 105.48/bbl and WTI at USD 102.10/bbl despite a session pullback, keeping real yield pressure elevated across risk assets. The VIX has ticked up 2.97% to 17.71, signalling a modest but real uptick in hedging demand ahead of a crowded policy calendar.
For Asia-Pacific markets, the cross-asset transmission is broad and asymmetric. USD/JPY has surged 1.29% to 156.38, reversing earlier yen strength and complicating the BoJ's position ahead of its widely anticipated 25 bp hike on September 18 — a weaker yen into a domestic rate decision raises the stakes for communication around the pace of further normalisation. USD/KRW has jumped 2.35% to 1,377.28, the sharpest move in the FX basket, reflecting Korea's dual exposure to US rate pressure and oil import costs given Brent above USD 105. The SSE shed 0.54%, HKEX dropped 1.00%, and the SGX fell 1.39%, with broad risk-off pressure concentrated in financials, energy importers, and rate-sensitive sectors. Copper's 1.10% gain and aluminium's 0.95% rise offer some offset for materials exporters, though ASX materials fell 2.21% on the session, suggesting the market is discounting near-term demand uncertainty over commodity price support.
