Soybean oil prices soared to a three-week high on Wednesday after the US launched new airstrikes against Iran and reimposed sanctions on Iranian oil sales. This escalation reignited concerns about disruptions to global supply chains for various commodities, including corn, soybean meal, fertilizer, and sugar.

The renewed US actions came in retaliation for a series of Iranian attacks on commercial vessels near the Strait of Hormuz, a critical choke point for global oil shipments. The US Treasury Department revoked a temporary sanctions relief agreement that had been in place, giving buyers of Iranian oil until July 17 to wind down existing transactions. This move follows a fragile ceasefire that had allowed Iran to freely sell tens of millions of barrels of oil from floating storage.

Simultaneously, crude oil prices also saw a significant rally. Brent crude climbed nearly 3% to reach $76 a barrel, while US West Texas Intermediate (WTI) crude surged almost 6%, pushing its price back above $70 for the first time since June 30. The US Navy-led Joint Maritime Information Center (JMIC) raised the transit threat level for the Strait of Hormuz to "severe" from "substantial," indicating that deliberate hostile action was now likely and advising extreme vigilance for mariners.
