US equities dip as oil swings amid fresh Iran conflict concerns

Wall Street closed lower after oil prices rose then fell on renewed worries about Iranian attacks in the Strait of Hormuz, while Treasury yields hit 24-year highs.

U.S. markets ended the session lower after oil prices fluctuated on renewed fears of Iranian disruptions to Middle-East shipping lanes. Initial price gains were sparked by a warning that Iran was stepping up attacks on tankers in the Strait of Hormuz, but the International Energy Agency announced that member countries could tap additional strategic reserves, prompting a price retreat. Treasury yields climbed to their highest point in 24 years, reflecting investor anxiety over the inflationary impact of higher oil costs.

The G7, in coordination with the IEA, had previously committed to release 100 million barrels of diesel and crude to mitigate supply concerns. Data from maritime tracker Kpler showed Gulf oil exports, excluding Iran, recovered to more than 81 percent of pre-war levels in September, though shipping firms face rising freight, insurance and security expenses. An incident earlier in the week left 12 crew members on a Panama-flagged tanker injured by an unknown projectile in the strait.

Why it matters

Oil price swings and rising Treasury yields affect global markets, borrowing costs and consumer prices.
