Saudi Aramco halted October crude oil deliveries to several European refiners following a pipeline attack in the Middle East, disrupting a key supply route.
Brent crude futures rose 2.8 percent to $93.45 a barrel, while West Texas Intermediate climbed 3.1 percent to $89.70 a barrel in early trading. The supply shock immediately pressured longer-dated Treasury yields as investors repriced inflation risk. The U.S. 10-year yield increased five basis points to 4.62 percent.
Energy costs carry outsized weight in headline CPI. A sustained crude rally here extends the timeline for central bank rate cuts—particularly in the Eurozone, where winter heating demand peaks in the coming months. The European Central Bank and Federal Reserve are monitoring the move closely; if oil remains elevated, restrictive policy may persist longer, extending duration risk for fixed-income portfolios already lever-long on rate volatility.
European refiners must now source crude from alternatives—West Africa, the North Sea, or the United States—likely at higher premiums. Regional crude differentials will widen. The incident also supports energy sector credit spreads, as upstream and downstream operators benefit from the tighter supply-demand balance.
