US Stocks Retreat from Record Highs as Middle East Tensions Send Oil and Treasury Yields Soaring

US financial markets experienced volatility driven by growing bond market concerns, which pushed Treasury yields to their highest levels in over 20 years, alongside fluctuating oil prices, despite recent record peaks for the Nasdaq and S&P 500.

Wall Street closed lower on Wednesday as oil prices experienced a roller coaster of rising and falling values amid renewed fears of supply disruptions in the Middle East. The downturn followed record-high closes on Tuesday, with US government bond yields climbing to 24-year highs as investors grew anxious over how high oil prices might impact inflation and interest rates.

Oil prices initially advanced on Wednesday following warnings that Iran appeared to be increasing attacks on tankers in the Strait of Hormuz. However, prices ultimately closed lower after International Energy Agency (IEA) member states announced their readiness to release additional strategic reserves.

The head of the IEA stated on Wednesday that member countries stand prepared to release more oil if necessary, prioritizing diesel due to tight fuel supplies. G7 nations, working in coordination with the IEA, agreed last Friday to immediately release 100 million barrels of diesel and crude oil to alleviate global energy supply anxieties stemming from the fallout of the United States-Iran war.

The latest IEA announcement successfully calmed oil markets following upward pressure earlier in the day, which had been triggered by a report from UK Maritime Trade Operations. The maritime agency reported on Tuesday that nine attacks on tankers had occurred in the Strait of Hormuz this month, accounting for half of September's total incidents in the waterway and the Gulf combined.

Meanwhile, US Secretary of State Marco Rubio reiterated Washington's position that it maintained control over the strait and that oil flows remained close to normal levels.

According to maritime experts and trackers, oil exports from the Gulf have rebounded significantly in recent days despite the surge in attacks on vessels near the Strait of Hormuz. Maritime intelligence firm Kpler reported that Gulf oil flows, excluding Iran, recovered to over 81 percent of pre-war levels in September, while wider Middle East crude exports exceeded pre-war levels on 14 days during the month.

Nevertheless, this recovery coincides with escalating attacks on tankers and soaring freight, insurance, and security expenses for shipping companies. Highlighting these ongoing risks, India’s Ministry of External Affairs reported that 12 crew members on a Panama-flagged tanker were injured on Tuesday during an attack by an unknown projectile while navigating the Strait of Hormuz.
