The Bitcoin Toll Booth at the Strait of Hormuz

Byline: Xiaobing, Deep Tide TechFlow

On April 8, the Financial Times published a report: Iran demanded that oil tankers transiting the Strait of Hormuz pay tolls in Bitcoin.

The source was Hamid Hosseini, a spokesperson for the Iranian Oil, Gas and Petrochemical Products Exporters Union. He told the FT that tankers must first email cargo information. After Iran evaluates it, it will provide a quote—$1 per barrel of crude oil. One fully loaded VLCC (very large crude carrier) carries 2 million barrels, so the transit toll is $2 million.

Payment method: Bitcoin. Hosseini said that, “payment is completed within seconds, ensuring it cannot be traced or confiscated due to sanctions.”

The consequences of not paying are also clear. As reported by the FT, a VHF radio broadcast in the strait warned: “Any vessel attempting to pass without authorization will be destroyed.”

A comprehensively sanctioned country has set up a Bitcoin toll checkpoint on the world’s most important oil shipping lane.

How the checkpoint was built

By the end of February 2026, the U.S. and the E.U.S. jointly targeted Iran, and Iran shut down the Strait of Hormuz in response. Data from S&P Global shows that tanker transit volumes through the strait plunged by 97%.

To understand the strait’s significance: before the war, 100 to 120 merchant ships passed through every day, and about one-fifth of the world’s crude oil goes through here. Once it was closed, oil prices skyrocketed and the global economy shook with it.

But after closing it for a while, Iran discovered that “closing” was not as good as “collecting.”

Starting in mid-March, the Islamic Revolutionary Guard Corps (IRGC) had already put into practice an unofficial, de facto transit-toll system. Ship owners were required to submit detailed information to an intermediary associated with the IRGC: vessel ownership records, flag registration, cargo lists, destination ports, crew rosters, and even AIS tracking data. After review and approval, the IRGC would issue one-time password permission codes and routing instructions, guiding ships to pass along the north side of Iran’s coastline, escorted by patrol boats.

On March 30 to 31, Iran’s parliament formally passed the Strait of Hormuz Management Plan, incorporating this system into law. Fees are denominated in rials, but authorization includes accepting payments in “digital currency.”

When the two-week ceasefire agreement between the U.S. and Iran was reached on April 7, this system had already been operating for at least three weeks.

A few hours after the ceasefire was announced, Hosseini publicly revealed the latest details in an FT interview: the toll must be paid in Bitcoin. His reason was to “ensure it cannot be traced or confiscated due to sanctions.”

Bitcoin or USDT: a test of sovereignty

Hosseini’s statements have two technical issues. Bitcoin transaction confirmations take minutes, not “seconds.” Every transaction on the Bitcoin blockchain is publicly verifiable, and firms like Chainalysis and TRM Labs are in the business of tracking funds on the Iran-linked chain. As early as 2018, OFAC sanctioned Iranian Bitcoin wallets.

But he was right about one thing: Bitcoin settlement does not go through the U.S. correspondent banking system, so OFAC cannot freeze it at the moment the transaction occurs. Post-event tracking is one thing; real-time interception is another. For a $2 million transit toll, “after the fact” is already too late.

TRM Labs’ report provides broader context. In recent years, what the IRGC has used more day-to-day is actually stablecoins such as USDT. Just two exchanges—Zedcex and Zedxion—were sanctioned by OFAC in January 2026, and they processed roughly $1 billion in IRGC-linked funds. Chainalysis’ 2026 Crypto Crime Report shows that in Q4 2025, addresses linked to the IRGC accounted for more than half of all crypto inflows to Iran, exceeding $3 billion.

The problem is that stablecoins have back doors.

Tether and Circle can freeze addresses. In mid-2025, Tether carried out what was reportedly the largest-ever freeze of Iran-linked funds.

That’s the logic behind the Strait checkpoint choosing Bitcoin. Daily trade settlements can use USDT without issue—the amounts are small, the transaction frequency is high, and it’s fast. But collecting a $2 million toll per shipment using a tool that a single issuer can freeze with a keypress at any time—that Iran is not willing to do.

Bitcoin has no administrator and no freeze button. Crypto enthusiasts have been shouting the slogan for 15 years; in the Strait of Hormuz, it has become a real-world need for a nation.

A Bloomberg report earlier also mentioned a third payment option: the Chinese yuan, routed through the Kunlun Bank via the CIPS system to bypass SWIFT. In effect, Iran offered ship owners a menu: those with good ties to China use yuan, while everyone can use Bitcoin.

Iran also devised a five-tier country classification system—“friendly” countries face lower rates, while vessels linked to the U.S. or Israel are outright denied passage. Some operators have already re-registered their ships under the Pakistani flag to obtain transit authorization.

$800 million per month—on par with the Suez Canal

TRM Labs estimates: if transit volumes return to normal, tankers alone could generate $20 million in revenue per day, bringing $600 million to $800 million per month. Add LNG and other cargo vessels, and it exceeds $800 million.

For comparison: in peak years, the Suez Canal’s monthly revenue is about at the same level.

Iranian officials themselves have also invoked the Suez Canal. In 1956, when Nasser nationalized the Suez Canal, Egypt collected payments from the same waterway for 70 years. In the best year, annual revenue reached $9.4 billion. When Iran’s parliament defended the Strait of Hormuz Management Plan, it explicitly cited the Suez precedent and even brought up Denmark’s historical tolls on the Sund Strait.

The core logic is the same: a country positioned at a key chokepoint monetizes geography.

But the differences are huge. Egypt has an international-law basis for sovereignty over the Suez Canal; the canal is man-made and belongs to Egypt’s territory. Hormuz is a natural strait. Under international law, it falls under a “strait used for international navigation.” Per UNCLOS, coastal states may not charge transit vessels for passage.

Iran’s response: we didn’t sign UNCLOS.

A Foreign Policy analysis article on April 7 put it plainly: if Iran can turn wartime temporary tolls into a permanent system for peacetime, this would be the largest economic and geopolitical event in the Middle East since Nasser nationalized the Suez Canal.

What is the market pricing in?

After the ceasefire news broke, Bitcoin jumped from around $68,000 to above $72,000. Once FT’s report on Bitcoin toll checkpoints came out, it surged again to around $73,000.

The market is pricing two things.

One old story: Bitcoin as a safe-haven asset. Since fighting between the U.S. and Iran began, Bitcoin has outperformed physical gold. The “digital gold” narrative fell quiet for a while, then returned to the spotlight.

One new story: Bitcoin as an international settlement tool. A sovereign nation collecting money in Bitcoin on the world’s largest energy chokepoint. This is not the scenario written in white papers. A country cornered by circumstances finds that outside the dollar system, Bitcoin is one of the few channels that can still receive payments.

The crypto community has debated for 15 years what Bitcoin is really for. Hormuz delivered an answer no one expected: when two countries go to war, the sanctions regime is fully activated, SWIFT is cut off, and stablecoins are frozen—Bitcoin is the last payment channel still operating.

This use case is real, but it’s also not exactly flattering.

In an ABC interview on April 8, Trump referred to the U.S.-Iran joint toll station as a “beautiful thing” and said he wants to set up “a joint venture.” A White House spokesperson promptly clarified that the premise of the ceasefire is that the strait must be “opened immediately, completely, and safely, without tolls.” The two sides’ statements clash.

Even more subtle is Trump’s own position. His family project, World Liberty Financial, launched a dollar stablecoin, USD1, and is partnering with Aster DEX to list oil futures settled in USD1. Bloomberg previously reported that payment methods Iran was accepting included dollar stablecoins—USDT and USDC among them. Trump’s family’s stablecoin business and Iran’s sanctions-evasion needs intersect in a subtle way around the word “stablecoin.”

After the checkpoint

FXStreet’s analysis pointed to a follow-up risk: if the military coercion + crypto payment model works through Hormuz, other chokepoints like the Strait of Malacca and the Bosporus could see imitators. The freedom-of-navigation rules maintained by the U.S. Navy for 80 years are not something that automatically gets enforced just because it is written on paper. And crypto happens to provide the technical possibility for “tolls” to bypass financial sanctions.

During the 1956 Suez Crisis, Nasser didn’t win because Egypt’s army could outfight the British and French coalition, but because the U.S. refused to support the invasion. That fait accompli then held. Seventy years later in Hormuz, it’s also a question of political will: how much cost is the U.S. willing to pay to reopen the strait?

For now, the outlook isn’t optimistic. The ceasefire hasn’t even held for 24 hours—Israel struck Lebanon with airstrikes, and Iran immediately halted passage through the strait again. Maersk said it was still in “emergency confirmation terms,” not daring to send ships. A shipping executive told CNBC very bluntly: “We have not received any information about how to pass safely.”

The ceasefire may not last beyond two weeks. But Iran has already proved something: a country kicked out of SWIFT, frozen out of dollar assets, and cut off from all traditional financial channels has built a toll system on the world’s most important maritime chokepoint using Bitcoin and stablecoins, with potential monthly revenue of $800 million—and someone has already paid.

The crypto industry spent 15 years proving the value of “decentralized payments.” In the end, the strongest proof wasn’t the startups in Silicon Valley or the institutions on Wall Street, but the IRGC on the Persian Gulf.

This probably wasn’t the scenario Satoshi Nakamoto envisioned in the white paper, but that’s the reality of 2026: technology doesn’t pick and choose users.
