Rubio warns Iran against Hormuz tolls as oil prices stay muted despite supply risk

US Secretary of State Marco Rubio said the US opposes any move by Iran to impose tolls near the Strait of Hormuz, arguing that the chokepoint does not belong to any nation state. The strait channels about 20% of global energy supply, and Rubio framed tolling proposals as a potential precedent while stressing that Washington is engaged in an agreement process with Iran but would not pursue a deal at any price. He added that outcomes should not run counter to the interests of US allies and partners.

Oil markets showed little immediate response. WTI traded lower near $69.50, around levels seen before the Middle East war, even as attention remained on shipping risks and policy signals. WTI, or West Texas Intermediate, is a US-sourced light, sweet crude benchmark distributed via the Cushing hub; its price is driven by supply and demand, the US Dollar and decisions by OPEC. Inventory data from the API and the EIA can also move prices; their readings are usually close, falling within 1% of each other 75% of the time. OPEC comprises 12 nations, while OPEC+ includes ten additional non-OPEC members.

Geopolitical Tensions Versus Market Response

We are observing a significant disconnect between geopolitical rhetoric and current market pricing. While US officials are taking a firm stance against potential Iranian actions in the Strait of Hormuz, the WTI price near $69.50 reflects market complacency. We see this as an opportunity, as the risk of a supply shock is being heavily underestimated.

The Strait of Hormuz is the world’s most critical oil chokepoint, with recent EIA data from early 2026 confirming that nearly 21 million barrels pass through it daily. This represents about 20% of the entire global oil supply. Any disruption, from implementing a toll to military escalation, would create an immediate and severe supply deficit.

Market Volatility And Strategic Positioning

Current market volatility is unusually low, with the CBOE Crude Oil Volatility Index (OVX) hovering near 32, a sign of calm that we view as unsustainable. This environment makes buying long-dated call options on WTI or Brent futures an attractive strategy. It offers a low-cost way to position for the significant upside potential if these tensions escalate in the coming weeks.

We only need to look back to the September 2019 attacks on Saudi oil facilities for a historical parallel. That event, which removed far less oil from the market than a Hormuz closure would, caused prices to surge over 14% in a single trading session. The current situation with Iran carries the potential for an even more dramatic price reaction.

Adding to our conviction is the current stance of OPEC+, which confirmed in its last meeting that it would maintain production quotas through the third quarter of 2026. This limits the spare capacity available to counteract a sudden supply loss from the strait. Therefore, any disruption would be felt more acutely and for a longer duration.
