The dominant macro driver overnight was the collapse of US-Iran truce negotiations over the Strait of Hormuz, with President Trump rejecting Iran's seven-day ceasefire proposal — which had conditioned reopening on sanctions relief and frozen-fund releases — and signalling military strikes could resume post-November midterms. Brent crude surged to approximately $107–108/bbl and WTI to $94.5–95.5/bbl on the news, amplifying inflation expectations and pushing US 10-year Treasury yields to approximately 5.23–5.27%, near 19-year highs, even as the 2-year fell 6bp to 4.81%, steepening the curve. The VIX rose 8.07% to 16.07, confirming a broad risk-off shift that pressured equities globally, with the S&P 500, Nasdaq and Nikkei all declining between 0.7% and 1.7%.
For European investors, the Hormuz shock compounds an already-elevated energy inflation backdrop: ECB staff projections released on 28 September put headline euro-area inflation at 3.0% for 2026, and Lagarde's parliamentary testimony flagged energy at 14.3% year-on-year in August as a primary upside risk. European equities absorbed the shock relatively well — the DAX fell only 0.13%, the CAC 40 was flat, and the Euro Stoxx 50 shed just 0.02% — but the cross-asset picture was less benign: German 10-year Bund yields rose a sharp 11bp to 3.18%, TTF front-month gas remains near 71–72 EUR/MWh with a Hormuz risk premium intact, and German power surged 16.2% to 165.05 EUR/MWh. Sector divergence was acute — Banks (+1.23%) and Oil & Gas (+1.12%) led European gains while Healthcare fell 0.25% and energy-intensive Chemicals came under pressure, exemplified by BASF dropping 3.59%. EUR/USD at 1.1378 and GBP/USD at 1.3229 reflect modest dollar strength (DXY +0.23% to 101.2) consistent with safe-haven flows, while EUR/GBP fell 0.10% to 0.8601 as sterling outperformed on BoE hawkish signalling.
