Oil prices gained on Tuesday as renewed fighting between the U.S. and Iran raised fears of supply disruptions from the Middle East, a key crude-producing region.5

Brent crude rose 2.7% and WTI increased 2.8%, reaching their highest levels since late August.

U.S. President Donald Trump threatened further strikes against Iran following recent attacks, heightening tensions in a conflict that had shifted to an economic standoff.

Tim Waterer, chief market analyst at KCM, noted, “These bring the potential for Iranian retaliation back into the equation,” which could damage energy infrastructure and disrupt shipping through the Strait of Hormuz.

The number of visible commodity vessels transiting the Strait dropped to five per day, according to shipping data from Kpler.2

Efforts by mediators, including Qatar and Oman, to reopen the Strait, which carried about a fifth of global oil supplies before the conflict, have stalled.

Highlighting ongoing risks, the UKMTO reported a tanker was struck by three projectiles while leaving the Strait, although no casualties or environmental impact were reported.6

Meanwhile, U.S. stocks fell on Monday, with the Dow Jones down 0.7%, the S&P 500 down 0.3%, and the Nasdaq down 0.1%, despite solid gains for the month, as rising oil prices stoked inflation concerns ahead of the Federal Reserve's September meeting.
