Iran Imposes Crypto Transit Tolls on Hormuz Shipping
Iran has moved to charge oil tankers cryptocurrency-denominated transit fees for passage through the Strait of Hormuz, exploiting the two-week ceasefire with the United States to assert financial control over one of the world's most critical shipping lanes.
According to the Financial Times, tankers carrying full cargo loads must email their cargo details to Iranian authorities before transit. Officials calculate a toll of approximately $1 per barrel and then instruct crews on how to settle the fee in digital assets, with Bitcoin cited as the preferred payment method. Empty tankers are exempt. Per-ship fees could reach as much as $2 million, according to The Block.
Hamid Hosseini, spokesperson for Iran's Oil, Gas and Petrochemical Products Exporters' Union, told the FT that crypto payments are being used specifically because they cannot be traced or confiscated under existing sanctions regimes. "Once the email arrives and Iran completes its assessment, vessels are given a few seconds to pay in Bitcoin, ensuring they can't be traced or confiscated due to sanctions," Hosseini said.
Tehran framed the monitoring requirement as a security measure, with Hosseini stating Iran seeks to ensure the ceasefire period is not used for weapons transfers through the strait.
The proposed framework carries a secondary operational risk for Western and Gulf-linked shipping firms. Iranian authorities indicated they may route compliant traffic along the northern passage of the strait, closer to Iran's coastline, waters that present heightened navigational and security risks for vessels not accustomed to operating there.
The episode represents a concrete, high-value application of cryptocurrency as a sanctions-circumvention tool. Iran joins Russia in deploying digital assets to access payments outside dollar-based financial channels. For shipping firms, the immediate question is whether compliance with Iran's crypto payment system creates its own legal exposure under US and EU sanctions frameworks, separate from the physical risk of transiting the strait itself.
Traffic through Hormuz remained low following the ceasefire announcement, with confusion over the new toll requirements contributing to hesitation among vessel operators.
