WASHINGTON, March 18 — Benchmark crude prices surged Monday after authorities announced a 20 percent transit toll on vessels passing through the Strait of Hormuz, a decision that immediately reset cost calculations for the world’s most heavily traveled oil route. Brent crude futures rose 3.2 percent to $87.50 per barrel, while West Texas Intermediate climbed 2.9 percent to $83.80 per barrel, according to data from the Intercontinental Exchange and the New York Mercantile Exchange.
The price moves reflect traders’ rapid assessment of how the new levy will ripple through supply chains that move roughly 17 million barrels of oil per day through the narrow waterway.
Shipping Costs and Revenue Estimates
The International Energy Agency calculates that the 20 percent toll could add $2.50 to the cost of each barrel of crude delivered to Asian markets. That estimate is based on a typical shipping cost of $12.50 per barrel for a Very Large Crude Carrier traveling from the Persian Gulf to Asia. Clarksons Research, a shipping analytics firm, notes that a single VLCC can carry 2 million barrels of oil.
At the announced toll rate, one such vessel would face a charge of approximately $500,000 per transit. Extrapolating from the daily transit volume of 17 million barrels—a figure that underscores the strait’s role as the single most important chokepoint in the global oil trade—daily toll revenue could reach $3.4 million.
The cost increase extends beyond crude. The International Group of Liquefied Natural Gas Importers estimates that the toll could raise the cost of shipping LNG from Qatar by 15 to 20 percent. Qatar is one of the world’s largest LNG exporters, and most of its shipments must pass through the Strait of Hormuz to reach customers in Asia and Europe.
The added expense compounds cost pressures already building in natural gas markets, where traders must now factor in not only the toll but also potential delays and administrative burdens at the chokepoint.
Disproportionate Impact on Asian Importers
The toll is expected to hit Asian refiners especially hard. China imported 1.2 million barrels per day from Saudi Arabia in 2024, making it the largest single-country buyer of Persian Gulf crude.
India imported 800,000 barrels per day from Iraq during the same period. Japan and South Korea are also significant buyers of crude from the region, relying on Persian Gulf supplies to feed their advanced refining industries. For these nations, the $2.50-per-barrel add-on represents a direct increase in delivered costs that refiners must either absorb or pass on to consumers in the form of higher gasoline, diesel, and heating fuel prices.
The modern oil market took shape in the mid-20th century as Middle East producers organized into OPEC in 1960 to coordinate supply and stabilize prices. The 1973 oil embargo demonstrated how a small group of exporters could disrupt global flows, triggering shortages and price spikes that reverberated through economies worldwide.
By the 1980s, new production outside the cartel—from the North Sea, Alaska, and Mexico—shifted some leverage away from OPEC, yet the Strait of Hormuz remained the single most important chokepoint. Any disruption or added cost at that narrow waterway has historically translated into higher delivered prices for refiners in Asia. Because crude is a globally traded commodity, its price reflects the balance between available supply and worldwide demand rather than the output of any single country.
OPEC and its allies periodically adjust production to influence prices, but geopolitical events, shipping routes, and infrastructure constraints can shift costs long before oil reaches refineries. Monday’s market reaction stems from a long-standing reality: any toll or restriction on the Strait of Hormuz immediately tightens the link between Middle East supply and Asian buyers.
The region supplies most of Asia’s imported crude, so even a small increase in shipping expenses ripples through regional supply chains and consumer prices. For consumers, that can mean higher gasoline and heating bills; for governments, it raises inflation risks and complicates energy security planning. The toll announcement therefore matters not as an isolated event, but as another reminder of how a handful of critical shipping lanes can shift the cost of a commodity that underpins modern economies.
