Iran has reached a new agreement to reopen the Strait of Hormuz, the narrow waterway through which roughly a fifth of the world’s oil supply passes daily. While early discussions pointed to a fee-free reopening, Iranian officials have since clarified that navigation through the strait will not be free of charge. The Iranian Foreign Minister stated explicitly that the final deal includes financial obligations, a significant pivot from the original no-toll premise that shaped early coverage of the agreement.

A new authority, a new toll booth

In May 2026, Iran established the Persian Gulf Strait Authority, or PGSA, a newly created body tasked with managing shipping approvals and collecting transit fees.

Reports from April 2026 indicated that intermediaries linked to the Islamic Revolutionary Guard Corps had begun accepting toll payments in crypto assets. The reported rates started at approximately $1 per barrel of oil transported, or roughly $2 million per vessel. Payment methods reportedly include stablecoins and yuan-denominated instruments, creating a dual-track system that sidesteps the US dollar-dominated financial infrastructure that underpins most international sanctions enforcement.

The sanctions evasion angle

Some vessels transiting the strait have reportedly opted to pay fees in crypto, while others are avoiding the route entirely due to concerns about sanctions exposure. The arrangement was reportedly established in coordination with Oman, which shares control of the strait’s shipping lanes.

What this means for crypto markets and investors

If IRGC-linked intermediaries are genuinely processing $2 million vessel payments in stablecoins, that represents real volume moving through crypto rails for geopolitical reasons. Increased use of crypto for sanctions evasion will almost certainly intensify regulatory pressure on stablecoin issuers and exchanges in Western jurisdictions, and evidence that digital dollars are being used to circumvent sanctions on Iranian oil transit would accelerate those efforts considerably.

Transit fees, whether paid in crypto or otherwise, represent additional costs that will eventually flow through to energy prices. Even at $1 per barrel, the aggregate impact across millions of barrels daily is meaningful.

If the US Treasury designates the PGSA or its payment intermediaries, that could trigger a cascade of compliance actions across crypto exchanges globally, freezing wallets, delisting tokens, and creating significant market disruption.
