The Toll Booth at the Throat of World Trade

In late February 2026, Iran closed the Strait of Hormuz to foreign shipping. What began as a chaotic wartime closure has, in the past few days, hardened into something more consequential: an official sovereign toll regime, codified in Iranian law, and priced in cryptocurrency.
On May 18, Iran operationally launched the Persian Gulf Strait Authority, a formal state bureaucracy with its own internet domain (pgsa.ir), account on X, and contact email. Since then, Tehran has delineated a “management supervision area” across the strait and announced a transit-permit scheme that converts Hormuz from an international waterway into a vetted toll plaza.
Under the plan, which formalizes procedures that had developed over the previous several weeks, operators must apply to the Persian Gulf Strait Authority via email and submit a “Vessel Information Declaration” covering ownership, insurance, crew, cargo, and routing. They then will receive a transit permit after paying a fee of up to $2 million per voyage, though it appears some fee-less safe-passages can be negotiated bilaterally.
More recently, Tehran has layered on a bitcoin-priced maritime insurance program called “Hormuz Safe” that, according to the nation’s semi-official Fars news agency, could generate $10 billion annually.
The U.S. government has responded swiftly, sanctioning the Persian Gulf Strait Authority on May 27 and reiterating warnings against providing any toll payments to the Iranian regime.
It’s important to focus on the payment instruments that Iran accepts for passage, as well as on the associated infrastructure, because they matter just as much as the establishment of the tolls themselves — and will determine the ultimate effectiveness of any response.
The tolls are crypto-denominated, to be paid either in bitcoin transferred to wallets linked to the regime’s Islamic Revolutionary Guard Corps or, according to reports, in dollar-pegged stablecoins. Payments have also been made through traditional bank wires, though even here there is a twist: The fees were settled in Chinese yuan routed through Kunlun Bank via the Cross-border Interbank Payment System, China’s Society for Worldwide Interbank Financial Telecommunications alternative. And while bitcoin and stablecoins are both cryptocurrencies — that is, digital currencies not issued by a central bank — they do have differing features, and those distinctions are doing real work in Iran’s broader strategy.
Indeed, while most readers are likely familiar with bitcoin, the Hormuz story should also draw attention to stablecoins, the less glamorous and more rapidly-growing part of the digital assets ecosystem — and the one with the deeper long-term geopolitical stakes.
Blockchain-based digital dollars have become load-bearing infrastructure in the contest over global economic power, quietly redrawing the architecture of international payments, empowering sanctioned regimes, and threatening authoritarian capital controls from within. The irony is that stablecoins were designed to be boring: Their very name denotes stable, reliable convertibility. And yet this modest-sounding instrument has, in a remarkably short time, become one of the most consequential financial technologies on the planet.
As a former federal prosecutor and senior U.S. Department of Justice official, I have worked at the nexus of emerging tech, illicit finance, and national security for over a decade. Today, I serve as an executive at a blockchain intelligence firm that has a commercial interest in this topic and supports both public and private sector entities in confronting financial crime. When I call for increased resources for blockchain analytics, I am not advocating for any specific platform or vendor, but rather for broader support of a rapidly developing field of intelligence that already has deep geopolitical impact.
Why Stablecoins Spread
Stablecoins solve a problem bitcoin cannot: they are stable enough to use as money. With a current total capitalization of roughly $260 billion, Tether and Circle dominate the market. And while a small cohort of non-dollar stablecoins pegged to the euro, the offshore Chinese yuan, the Russian ruble, and even gold have also emerged —with Hong Kong dollar-pegged instruments on the way — U.S. dollar-denominated coins still represented roughly 97 percent of the entire market as of 2025.
