The latest escalation between the United States and Iran has transformed an oil-supply shock into a broader repricing of global sovereign debt, with higher energy costs feeding inflation expectations and pushing central banks toward a more hawkish stance.
Brent crude climbed to $95.68 a barrel on 2 September after touching $97.04 earlier in the session, while West Texas Intermediate reached $90.73. The advance marked a third consecutive daily gain following fresh U.S. airstrikes on Iranian Revolutionary Guard targets near Bandar Abbas and Chabahar, and retaliatory Iranian missile and drone attacks on U.S. bases in Jordan and Bahrain. Two supertankers carrying Saudi crude were struck by unidentified projectiles near the Strait of Hormuz on Monday, adding to fears that the waterway — historically handling around a fifth of global oil trade — could face further disruption.
The bond-market reaction has become the more important story. The U.S. 10-year Treasury yield reached 4.8122%, Japan's 10-year yield traded above 3% for the first time in 30 years, and Britain's 10-year gilt hit 5.2501%, its highest since June 2008. The 30-year gilt reached 5.8909%, the highest since March 1998. Reuters linked the selloff directly to energy prices and inflation risk, while government deficits, sovereign issuance and technology-company borrowing added pressure. Disruption extended beyond crude: Qatari and Emirati LNG cargoes were transferred between ships outside Hormuz, with Asian spot LNG trading at more than twice pre-conflict levels.
Iranian crude exports have collapsed from roughly 2 million barrels per day in March to between 220,000 and 255,000 barrels per day in August, according to Kpler and Vortexa. However, broader regional flows have not stopped completely: U.S. Energy Secretary Chris Wright said 17 million barrels moved through Hormuz on Monday, although preliminary tracking showed only four commodity vessels transiting Tuesday versus a 10-day average near 13. U.S. crude inventories fell by 2.6 million barrels for the week ending 28 August, according to the American Petroleum Institute.
The monetary-policy calendar is repricing quickly. Eurostat reported euro-area inflation at 3.3% in August, with energy inflation at 14.3%. Markets now expect the European Central Bank to raise rates on 10 September, while CME pricing put the probability of a Federal Reserve quarter-point hike on 15-16 September at about 68.2%. The Bank of Japan meets on 17-18 September amid yen weakness and higher import costs.
Treasury Secretary Scott Bessent argued the Strait of Hormuz could become "worthless" within two years as Gulf nations build pipeline alternatives. Yet prediction traders remain skeptical of a quick normalization: Polymarket showed only a 2.8% probability of normal Hormuz traffic by 30 September. If shipping normalizes, oil may surrender part of its risk premium, but the bond-market shift may prove stickier because fiscal deficits and debt supply remain. That is why Brent above $95 is now a bond story: the barrel is the trigger, but markets are repricing the cost of money.
