30-Year US Treasury Yield Hits 5.38% Amid Energy Crisis

Sovereign debt yields rose globally as Middle East conflict pushed oil prices above $100 per barrel. The 30-year US Treasury yield reached its highest level since 2007.

The 30-year US Treasury yield climbed past 5.38 percent on Friday. This marked the highest level for the instrument since 2007. The 10-year US Treasury yield approached the 5 percent threshold, settling near 4.95 percent in European morning trading. These moves reflect growing expectations for tighter monetary policy.

Global bond markets reacted to worsening hostilities in the Middle East. Investors priced in the risk that sustained energy costs would keep inflation elevated. This scenario would force central banks to maintain restrictive interest rates for longer than previously anticipated. The cost of credit for governments and corporations is rising as a result.

Energy Disruptions Drive Inflation Risks

Brent crude oil traded above 100 dollars per barrel in recent sessions. The nearest-month futures contract quoted near 106 dollars per barrel on Friday morning. Iran-supported Houthi groups in Yemen attacked Saudi energy facilities. They also advanced toward the Bab el-Mandeb Strait, a critical route for global energy shipments.

The Strait of Hormuz remains largely closed due to ongoing conflict. This disruption threatens global supply chains for fuel. Higher input costs for energy are expected to feed into broader price increases. Markets are positioning for a potential second wave of inflationary pressure.

European Yields Follow ECB Hawkish Turn

European sovereign borrowing costs accelerated after the European Central Bank raised its deposit facility rate. The rate increased from 2.25 percent to 2.50 percent on Thursday. The bank warned that price growth could remain above target for an extended period. This stance prompted investors to bet on further tightening.

The German 10-year Bund yield stood at approximately 3.50 percent on Friday morning. French 10-year yields were near 4.44 percent, 94 basis points higher than Germany. Italian 10-year paper yielded about 4.37 percent. Spanish equivalents traded near 3.96 percent. These figures show a widening spread among southern European debt issuers.

UK and US Markets See Multi-Year Peaks

British 10-year government bond yields drifted toward 5.35 percent on Friday. The yield had touched 5.378 percent on Thursday, its highest point since 2007. Long-dated UK gilts also reached new peaks, with 20-year yields at 5.895 percent and 30-year yields at 5.948 percent. These levels have not been seen since 1998.

US wholesale inflation data showed rising prices, strengthening the case for Federal Reserve action. Markets now expect the central bank to lift rates in the coming week. The combination of high oil prices and sticky inflation is compressing the valuation of long-duration fixed-income assets. According to GN auto markets/bonds: bond yields, this trend signals a structural shift in global debt pricing.
