Oil prices firmed up on Monday, with the United States Oil Fund (AMEX:USO) climbing 2.57% to 129.35 dollars, as traders weighed a proposal from President Trump to impose a Hormuz toll on shipping traffic through the strategic waterway. The fund now sits comfortably within its 52 week range of 102.42 to 143.78, with an RSI of 53.55 suggesting the move has room to run before hitting overbought territory.

A Toll That Could Reshape Energy Trade
The proposal at the center of this week's oil market jitters is straightforward in concept but extraordinary in scale: a 20 percent charge on the commercial value of cargo passing through the Strait of Hormuz. Before recent regional disruptions, roughly 21 million barrels of oil and petroleum products moved through the strait daily. At an illustrative price of 70 dollars per barrel, that flow represents about 1.47 billion dollars in cargo value every single day. A fifth of that, applied as a toll, would add close to 294 million dollars per day, or more than 107 billion dollars annually, to oil shipments alone.
The math shifts with price, naturally. At 60 dollars a barrel, the annual toll on oil would still run close to 92 billion dollars. At 80 dollars, it would top 122 billion. None of this accounts for the roughly 10 billion cubic feet of liquefied natural gas that also transits Hormuz each day, mostly originating from Qatar. Valued conservatively at 10 dollars per million British thermal units, the LNG toll alone would add another 7.5 billion dollars a year. Combined, the levy on oil and gas could approach 115 billion dollars annually under fairly moderate price assumptions, before even counting petrochemicals, fertilizers or general cargo.
Why USO Is Reacting Now
USO tracks the price of West Texas Intermediate crude futures, so its 2.57 percent gain reflects traders pricing in the possibility that a chunk of global oil supply becomes structurally more expensive to move. Markets tend to price uncertainty well before any policy is formally enacted, and that appears to be happening here. Shipping companies, insurers and commodity desks are already recalculating risk premiums tied to a waterway that carries a fifth of the world's seaborne oil.
Legal Questions Around the Hormuz Toll Proposal
The legal footing for such a charge looks shaky. International law generally grants ships a right of transit passage through international straits, and coastal states are not supposed to obstruct that passage with tolls or discriminatory fees. The International Maritime Organization has stated plainly that there is no legal basis for a country to impose payments on transit through an international strait. The United States is not even a coastal state bordering Hormuz, which makes its claim to collect a percentage of cargo value more unusual than if Iran or Oman had proposed the same thing.
That distinction matters for how the policy is likely to be received. Washington has spent months and considerable military resources arguing that Iran cannot be allowed to close or extort payment from an international waterway. Swapping an Iranian blockade for an American toll would blur that argument considerably, making the intervention look less like a defense of free navigation and more like a dispute over who gets paid.

Supply Routes, Inventories and the Dollar's Role
Alternatives to Hormuz exist but they are limited. Some oil could be rerouted through pipelines connecting Saudi Arabia and the United Arab Emirates to terminals outside the Gulf, though those systems lack the capacity to absorb the full volume that normally passes through the strait. LNG has even fewer options, since Qatar's exports depend almost entirely on maritime access through Hormuz.
USO's price action also reflects the broader dollar dynamic that shapes crude markets. Oil is priced in dollars globally, so any policy that raises the effective cost of a major supply corridor tends to ripple through inventories, insurance markets and currency flows simultaneously. War risk insurance premiums have already climbed, and financing costs for cargoes moving through contested waters are rising as lenders treat that oil as riskier collateral. Traders are widening the margins they build into contracts, and buyers are exploring supply routes that avoid the charge altogether.
A Feedback Loop Worth Watching
There's a mechanical problem embedded in a percentage based toll: it rises automatically with the price of oil. Disruption pushes prices up, the toll rises with those prices, shipping costs climb further, and uncertainty pushes insurance and financing costs higher still. That loop could eventually dampen demand rather than simply redistributing revenue, since consumers facing higher fuel costs tend to cut back, and governments accelerate efforts to diversify away from imported hydrocarbons.
An Unlikely Boost for Alternative Energy
There's an irony running through this proposal that traders and policymakers alike have noticed. Renewable electricity, nuclear power, domestic hydropower and battery storage would not pay a Hormuz toll of any size. Electric vehicles become relatively more attractive as oil costs climb, and heat pumps offer protection against volatile LNG pricing that gas fired heating cannot match. None of these technologies need to cross a strait that a foreign government might tax or blockade.
Saudi Arabia, Qatar and the United Arab Emirates still hold some of the lowest cost hydrocarbon reserves on the planet, and producers could pass part of any toll on to consumers rather than absorbing it entirely. But long term investment decisions in Gulf energy projects hinge on more than extraction costs. Market access, political stability and confidence in predictable trading rules all factor into whether a project gets built. A recurring 20 percent levy would complicate all three, and that uncertainty tends to show up in inventory and production planning long before it shows up in a headline price.
Where Does Oil Price Uncertainty Go From Here?
USO's move to 129.35 dollars, still well below its 52 week high of 143.78, suggests traders view this as a live risk rather than a settled outcome. Whether the toll gets implemented as announced, watered down through negotiation, or abandoned entirely will determine whether Monday's gain holds or reverses. For now, the RSI reading near 54 shows a market that has room to move in either direction depending on how this policy debate resolves.
