Your gas bill is about to feel this one. President Donald Trump announced Monday that the United States will reinstate its naval blockade of Iranian ports and charge a 20% fee on all cargo shipped through the Strait of Hormuz — and oil markets erupted within hours.
What Trump Announced on the Strait of Hormuz
In a Truth Social post, Trump declared the U.S. would from now on be known as the “Guardian of the Hormuz Strait,” saying the country will be reimbursed at a rate of 20% on all cargo shipped through the waterway to cover the cost of providing security in the region. He doubled down in a Fox News phone interview Monday morning, saying the U.S. guarded the strait “for nothing” for years and now intends to get paid for it.
The Strait of Hormuz is the single most important oil chokepoint on the planet — roughly a fifth of the world’s oil supply typically moves through it. With the U.S.-Iran conflict grinding on, commercial traffic has already collapsed: ship-tracking data showed only six vessels transited the strait on Sunday, compared to a normal daily count of well over one hundred.
Oil Prices Surge: The Numbers
Markets moved fast. U.S. crude closed up 9.4% at $78.14 per barrel Monday, while international benchmark Brent crude jumped 9.6% to $83.30 — Brent’s largest single-day jump since May 2020. Bloomberg calculated that a 20% fee at current prices works out to roughly $30 million per full supertanker.
$4 Gas Prices: When It Hits Your Pump
Here’s the part that matters for Kentucky drivers. GasBuddy analyst Patrick De Haan says he expects the national average gas price to hit $4 per gallon within 7-10 days — possibly sooner — with retailers starting to pass along increases within 24-48 hours. If you’ve got a road trip planned or you run vehicles for your business, this week is the time to plan around it.
The Pushback Is Already Here
Receipts over rhetoric: the plan is not a done deal. The International Maritime Organization rejected the toll idea within hours of Trump’s announcement. Energy and shipping companies loudly rejected a nearly identical toll scheme when Iran proposed it — and the U.S. Treasury Department itself previously branded paying for passage through the strait “maritime extortion.” How a 20% cargo fee would actually be collected, and by whom, remains completely unclear.
What is clear: five months of conflict have drawn down global oil inventories, Chinese refineries are ramping up crude imports, and every escalation in the Gulf now lands directly on American wallets.
