NextFin News - Global oil markets experienced heightened volatility on Tuesday as investors grappled with the prospect of Iran imposing transit fees on vessels crossing the Strait of Hormuz as part of a potential ceasefire deal with the United States. Brent crude rose 2.5% to $98.47 a barrel, while West Texas Intermediate fell, reflecting a highly fragmented market. This divergence unfolded as U.S. Central Command conducted defensive strikes in Iran, contrasting with U.S. President Trump's weekend hints that a peace agreement to end the three-month conflict might be near.
Dave Ernsberger, president of S&P Global Energy, said on CNBC's 'Squawk Box Europe' on Tuesday that investors are afraid to take a position due to the highly contradictory messaging surrounding the negotiations. Ernsberger, a veteran energy market observer known for his pragmatic, data-driven analysis of global supply chains, has historically maintained a cautious stance on geopolitical risk premiums, often arguing that physical flows eventually override short-term political posturing. He warned that the proposed transit fee—rumored to be around $1 per barrel—represents a fundamental challenge to the principle of freedom of navigation.
This warning of investor paralysis is widely shared among physical traders, but some financial analysts argue that a $1-per-barrel toll is a manageable friction that the market would quickly absorb once supply certainty is restored. This perspective is not yet a consensus on Wall Street, where opinions remain divided between those who see the toll as a dangerous precedent and those who view it as a pragmatic cost of peace. The proposed fee, framed by Tehran as an environmental fee or transit toll to be jointly regulated with Oman, would target the narrow waterway through which one-fifth of the world's seaborne oil passes.
Iranian foreign ministry spokesman Esmail Baghaei sought to downplay the term toll in a press briefing, stating that while there is no toll, the navigation and the preservation of the ecosystem of the Strait, the Persian Gulf, and the Sea of Oman will have costs. The ambiguity has left shipping companies and commodity traders in limbo, unsure of how to price the risk of transit through the chokepoint.
Significant uncertainties remain regarding the economic and legal feasibility of such a charge. An analysis by the Bruegel think tank suggests that a Hormuz toll would act as a partial supply tax, with Gulf exporters bearing a significant portion of the cost because they cannot easily pass it on to global buyers who have access to non-Gulf crude. Furthermore, any such toll would face severe legal challenges under international maritime law, specifically the 1982 UN Convention on the Law of the Sea, which guarantees the right of transit passage through international straits.
If U.S. President Trump rejects the toll as a tax on trade, negotiations could collapse, potentially reigniting the military conflict and pushing Brent crude back toward its recent high of $126 a barrel. For now, the shipping industry is left waiting to see if the price of peace in the Middle East will indeed be paid at the toll booth of the world's most critical energy chokepoint.
