CENTCOM says its forces have redirected 20 commercial vessels, disabled two and boarded two others while enforcing the U.S. blockade against Iran. Prediction markets have lifted the odds of a Bab el-Mandeb Strait closure by September 30 to 20.5%, and Glencore expects roughly $3 billion from a Marketing segment trading the same disruption.
CENTCOM has redirected 20 commercial vessels, disabled two, and boarded two others in continued enforcement of the U.S. blockade against Iran. The blockade was reimposed after being lifted on June 18 and has escalated to include physical interventions in shipping lanes.
Enforcement widens in the Strait of Hormuz
Those interventions belong to the 2026 U.S.–Iran maritime confrontation in the Strait of Hormuz and Gulf of Oman. CENTCOM's actions appear to escalate that confrontation, and the enforcement measures are consistent with heightened geopolitical tensions that could reach broader shipping operations in the region.
Meanwhile, traders have started pricing a second chokepoint. Market pricing suggests a potential increase in the likelihood of a Bab el-Mandeb Strait closure by September 30, with odds rising to 20.5% from 16% in the past 24 hours.
Glencore expects $3 billion from its Marketing segment
Glencore expects roughly $3 billion in profit from its Marketing segment for the first half of 2026, driven by extreme market volatility tied to a military conflict near the world's most important oil chokepoint. The Swiss commodities group disclosed the figure in its half-year production report on Wednesday, reporting adjusted EBITDA of $18.9 billion, a 119% increase on the same stretch last year.
But Glencore is not the only desk earning from the volatility. Wall Street banks are on track for as much as $40 billion in trading revenue tied to the same Iran-related volatility. ExxonMobil raised its Q2 upstream income guidance by $3.5 billion to $3.9 billion, citing Hormuz-related supply shocks.
A fifth of daily oil demand runs through the corridor
The Strait of Hormuz handles roughly a fifth of the world's daily oil consumption, and a credible military threat near that corridor moves prices and creates the bid-ask spreads and regional price dislocations sophisticated trading desks are built for. For now the windfall appears to be staying with commodity traders and energy majors rather than rotating elsewhere.
