The Tollbooth
Iran just used Bitcoin to collect tolls at the most important chokepoint on earth. What does it mean for the future of money?
$1 per barrel.
That’s the fee Iran is charging for every barrel of crude oil that passes through the Strait of Hormuz, the 21 mile wide gap between Iran and Oman through which roughly 20 million barrels per day of crude oil and petroleum products flowed in 2025: one fifth of global consumption. And they want it in Bitcoin.
On March 30, 2026, Iran’s parliament approved the “Strait of Hormuz Management Plan,” a law codifying a toll system the Islamic Revolutionary Guard Corps had reportedly been operating on the ground since mid March. A fully laden VLCC supertanker carrying roughly two million barrels of crude pays approximately $2 million. The IRGC has reportedly charged ships up to $2 million per vessel since mid March, accepting payment in Chinese yuan, Bitcoin, and potentially the stablecoin USDT. At current traffic levels, public estimates suggest the toll system could generate up to $20 million per day from oil tankers alone, with $600 to $800 million per month possible if liquefied natural gas vessels are included.
Let that sink in for a moment. A sovereign nation has written cryptocurrency payment rails into law for the most critical shipping lane on the planet.
To understand the magnitude of what Iran has done, you need to understand the Strait of Hormuz itself. The numbers are almost absurd in their concentration of risk.
The strait is 21 nautical miles wide at its narrowest point. Two shipping lanes, each about two miles across, separated by a two mile buffer zone. On any normal day prior to February 28, 2026, approximately 138 commercial vessels passed through those lanes. Saudi Arabia, the UAE, Kuwait, Qatar, Iraq, Bahrain, and Iran all funnel their energy exports through this single passage. In 2024, 84% of crude oil and condensate shipments through the strait were destined for Asian markets, with China receiving a third of its oil via Hormuz.

Now let’s get back to it!
Then the war started. On February 28, 2026, following coordinated U.S. and Israeli strikes on Iran, Iran’s Revolutionary Guard Corps declared the Strait of Hormuz closed to Western allied shipping. Tanker traffic collapsed almost immediately. On March 7, a single commercial vessel transited the strait. One. The historical daily average is 138 ships. Brent crude oil jumped from $71 per barrel on February 27 to $94 per barrel by March 9, and kept climbing from there, reaching approximately $128 per barrel on April 2 before pulling back to around $95 as ceasefire talks have progressed.
The EIA’s April Short Term Energy Outlook expects disrupted crude oil production to peak at 9.1 million barrels per day in April before gradually falling over the coming months. Persian Gulf oil producers have been forced to cut production by roughly 6% because local storage facilities are reaching capacity. The IEA has warned that the ongoing conflict could wipe out global oil demand growth this year, resulting in the first annual decline since the pandemic. Goldman Sachs is projecting a Q2 2026 Brent average of $110, with an extreme upside scenario of $135 if flows remain disrupted for six months or more.
Only Saudi Arabia and the UAE have any pipeline infrastructure capable of bypassing the strait. The Saudi East West Petroline has a design capacity of 5 million barrels per day, and the UAE’s Abu Dhabi Crude Oil Pipeline adds another 1.5 to 1.8 million. Combined available bypass capacity tops out at roughly 3.5 to 5.5 million barrels per day, barely a quarter of what normally transits Hormuz. Five major producing countries: Iraq, Kuwait, Qatar, Bahrain, and Iran itself, have zero pipeline bypass infrastructure. Roughly 14 million barrels per day are structurally locked to this single maritime passage.
The world just learned, in real time, what happens when someone puts a tollbooth on the jugular vein of global energy.
Why Bitcoin?
Now here’s where it gets interesting. Iran didn’t just set up a toll system. They specified the payment method: digital currencies, with Bitcoin explicitly named.
Hamid Hosseini, a spokesperson for Iran’s Oil, Gas and Petrochemical Products Exporters’ Union, told the Financial Times that tankers would need to email Iranian authorities about their cargo, after which Iran would inform them of the toll to be paid in digital currencies. His exact words: “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.”
Can’t be traced or confiscated due to sanctions.
That’s the sentence that matters.
To understand why Iran chose Bitcoin specifically (as opposed to other crypto assets), you have to understand what happened with their stablecoin experiment. Iran has been building a parallel financial system using cryptocurrency for years. Chainalysis reported that Iran’s crypto ecosystem reached $7.78 billion in 2025, growing faster than the year before. The Islamic Revolutionary Guard Corps, Iran’s primary military branch, accounted for more than 50% of total Iranian crypto inflows in Q4 2025, with over $3 billion in value received last year alone.
But here’s the critical detail: most of Iran’s crypto activity ran through USDT (Tether) on the Tron blockchain. The IRGC, the Central Bank of Iran, their proxy networks: they all leaned heavily on stablecoins for settlement. Elliptic reported that the Central Bank of Iran accumulated at least $507 million in USDT, using it both for domestic foreign exchange intervention (trying to prop up the collapsing rial) and for what Elliptic described as “digital off book eurodollar accounts”: a shadow financial layer for settling cross border trade outside the reach of U.S. authorities.
And then Tether shut it down. On June 15, 2025, Tether blacklisted several wallets linked to the Central Bank of Iran, freezing approximately $37 million in USDT. Tether froze 42 additional Iran linked addresses in July. In September, Treasury sanctioned a $600 million Iranian shadow banking network that had been moving value in stablecoins.
Most recently, in March 2026, both Tether and Circle blacklisted wallet addresses linked to the Iranian crypto exchange Wallex, cutting off USDT and USDC access. Tether alone has blacklisted over $3.3 billion in USDT across more than 7,000 wallets since 2023.
And this is the key insight: stablecoins aren’t censorship resistant. They are programmable dollar instruments with a kill switch. Tether can freeze any wallet, at any time, on any chain. Circle can do the same with USDC. Both issuers have built in blacklist functions at the smart contract level. When an address gets flagged, the transfer function simply reverts. Your money is gone. You can see it in your wallet, but you can’t move it, trade it, or redeem it.
For ordinary commerce, this is a feature. It lets law enforcement recover stolen funds and comply with sanctions. But for a sovereign state trying to collect transit fees at a maritime chokepoint while under comprehensive U.S. sanctions, it’s a dealbreaker. Iran learned this the hard way after watching hundreds of millions in USDT get frozen by a company incorporated in the British Virgin Islands.
Bitcoin doesn’t have a kill switch. There is no company to call, no compliance department to freeze your wallet, no blacklist function embedded in the protocol. Once a Bitcoin transaction is confirmed on chain, it’s done. Final settlement. No chargebacks, no reversals, no third party with the power to reach into the protocol and undo the transfer. This is what the cypherpunks meant when they designed Bitcoin as “peer to peer electronic cash.” It’s bearer digital money: like physical cash, but transmissible across borders at the speed of the internet.
For years, the Bitcoin debate has been framed around price. Will it go to $100K? $500K? $1M? And the critics have had their own set of talking points: it’s too volatile, it uses too much energy, it’s only for criminals. The Hormuz toll system demolishes this framing entirely, because it forces a much more fundamental question: what happens when the properties of money matter more than its price?
Iran didn’t choose Bitcoin because it’s a good investment. They chose it because it’s the only form of money available to them that no third party can confiscate, freeze, or censor. They chose it because the payment rails themselves are permissionless, meaning no government, corporation, or international body can prevent the transaction from settling.
This is where the theoretical becomes practical in the most visceral way imaginable. We can have academic debates about whether Bitcoin is “money” until the end of time. But when a sovereign nation is collecting tolls on 20% of global oil supply and specifying Bitcoin as the payment method because it’s the only instrument that can’t be interdicted by U.S. sanctions enforcement, the theoretical debate is over. The properties of Bitcoin as money are being tested in the most extreme geopolitical conditions on the planet, and they’re performing exactly as designed.
Let me be very clear: I am not making a moral argument here. Iran is a sanctioned regime for reasons. The IRGC is designated as a foreign terrorist organization. The toll system itself may well constitute a violation of the UN Convention on the Law of the Sea. These are legitimate policy concerns. But the technical reality doesn’t care about the policy concerns. Bitcoin works for Iran precisely because it was designed to work for anyone, regardless of what any government thinks about the transaction.
That’s what “permissionless” means. And the implications extend far beyond Iran.
The Bitcoin Policy Institute published an excellent analysis of the Hormuz situation that I’d encourage everyone to read. One of the most important points they make is that the Hormuz story matters less for what Iran is doing today and more for what it reveals about Bitcoin’s growing prominence as a strategic asset. And they’re right.
Consider what has happened in the last 12 months alone:
The Trump administration signed an executive order on March 6, 2025 establishing a Strategic Bitcoin Reserve, seeded with roughly 200,000 BTC from federal seizures. The order explicitly calls Bitcoin “digital gold” and states that assets in the reserve “shall not be sold and shall be maintained as reserve assets of the United States.” The BITCOIN Act in Congress goes even further, proposing that Treasury directly purchase up to 1 million Bitcoin, approximately 5% of total supply, mirroring the size and scope of U.S. gold reserves.
El Salvador, the first country to adopt Bitcoin as legal tender back in 2021, has grown its strategic reserve to 7,565 BTC as of February 2026, worth roughly $560 million at current prices. They’ve been buying one Bitcoin per day through a disciplined dollar cost averaging strategy, regardless of market conditions. President Bukele’s team has also allocated $50 million to gold purchases, creating a hybrid reserve structure that blends traditional and digital stores of value.
In May 2025, the International Monetary Institute, a CCP backed think tank at Renmin University closely affiliated with the People’s Bank of China, republished a report making the case for Bitcoin as a reserve asset. Their editorial note was explicit: Bitcoin is transitioning from a speculative asset to a strategic reserve asset. In April 2026, the Bitcoin Policy Institute published a paper arguing that Taiwan should hold Bitcoin as financial insurance against a potential Chinese blockade. Taiwan’s Executive Yuan and Central Bank are reportedly evaluating the proposal.
And now Iran is using it to collect tolls at the world’s most important energy chokepoint.
Something has shifted. The conversation is no longer about whether nation states will engage with Bitcoin. The conversation is about what happens when they do.
As I laid out in BRICS: A Ghost Threat?, the fundamental problem with creating a new reserve currency is that any fiat alternative inherits the same structural weaknesses as the dollar system it’s trying to replace. The Triffin dilemma doesn’t disappear just because you change the flag on the currency. Any issuing nation (or bloc of nations) must run constant current account deficits to supply the world with reserve liquidity, must have deep and liquid capital markets where excess reserves can be recycled, and must maintain minimal capital controls.
No BRICS fiat currency can do this. The countries that make up BRICS have fundamentally incompatible economic interests, different monetary policy needs, and active border disputes with each other. A common enemy can create the strangest of bedfellows, but it can’t sustain a monetary union.
But Bitcoin sidesteps the entire dilemma. Nobody issues it. No single nation controls it. There are no capital controls to worry about because there is no capital account: Bitcoin exists on a global, borderless network where a transaction between Tokyo and Tehran settles the same way as one between New York and London. There is no Triffin dilemma because no sovereign must debase their economy to supply the world with Bitcoin liquidity; supply is fixed at 21 million coins by the protocol itself, enforced by mathematics and distributed consensus.
This is what I wrote back in 2023: “Bitcoin essentially is the only real solution here. A decentralized, permissionless, non state issued currency that can cross borders easily and (relatively) quickly.” The caveat I gave then was liquidity: the Bitcoin market was simply too small to handle the volumes and price pressures a global reserve currency faces.
That’s still true today. Bitcoin’s market cap sits around $1.33 trillion. The U.S. Treasury market alone is north of $35 trillion. Global foreign exchange reserves exceed $12 trillion. Bitcoin isn’t ready to be the global reserve asset. Not yet.
But Iran just demonstrated something that cuts through the liquidity argument entirely: for specific, high value transactions where the properties of the money are more important than the depth of the market, Bitcoin already works. A $2 million toll payment on a supertanker doesn’t need the same market depth as settling $500 billion in daily FX turnover. It needs censorship resistance, final settlement, and permissionless access. Bitcoin delivers all three.
The Bitcoin Policy Institute notes that blockchain analytics firms have found little on chain evidence of Bitcoin moving at scale for Hormuz transit payments; the actual settlement may be happening primarily through yuan and stablecoins, with Bitcoin serving more as the stated policy framework than the dominant payment rail. That’s a fair caveat. But the strategic signal matters more than the transactional volume. A sovereign nation has publicly stated, through formal parliamentary legislation, that Bitcoin is an acceptable payment instrument for critical state revenue collection. The precedent is set whether the on chain volume backs it up or not.
The flip side of this story is what’s happening to ordinary Iranians. The rial has lost more than 96% of its value against the dollar. An estimated 22% of Iranians now hold digital assets, driving $4.18 billion in outflows in 2024 as the currency continued its multi year collapse. Chainalysis observed a significant surge in withdrawals from Iranian exchanges to personal Bitcoin wallets during recent mass protests, particularly before the January 2026 internet blackout.
Digital assets in Iran function as both a state evasion tool and a household lifeboat. The IRGC uses crypto to finance proxy networks, procure weapons components, and settle oil sales. Ordinary Iranians use it to preserve purchasing power as their government’s monetary incompetence destroys their savings. Same network, same protocol, radically different purposes. The protocol doesn’t know the difference. That’s the point.
This dual use pattern is something we’ve seen play out in country after country. In Lebanon, where the banking system froze depositors out of their own accounts. In Turkey, where the lira has been in freefall. In Nigeria, where capital controls drove Bitcoin premiums to 60% over international spot prices. In Argentina, where we covered the endgame dynamics in detail. The pattern is always the same: citizens of failing monetary systems reach for whatever store of value they can access that their government can’t debase, freeze, or confiscate.
For gold, this meant physical possession, with all the storage, transport, and divisibility problems that come with it. For dollars, it meant black market exchange rates and the constant risk of seizure. Bitcoin offers something neither of those alternatives do: the ability to store and transmit value across borders, in any amount, without physical custody requirements, without intermediaries, and without anyone’s permission.
As I wrote years ago, in the modern technocratic internet age, money needs to move as fast as information does, and a slow, heavy, physical form of money simply won’t do. Gold would inevitably wind up in banks, exchanged for digital units of account, which puts us right back where we started. Bitcoin is the escape hatch from that loop.
What Iran has done at Hormuz is a proof of concept, not a revolution. The volumes are relatively small. The on chain evidence is thin. The ceasefire may hold and normal traffic may eventually resume.
But the template is set. The next time a sanctioned country controls a chokepoint, the next time trade settlement needs to route around the dollar system, the next time a central bank needs to move value outside the reach of OFAC and Tether’s compliance department: the playbook exists. Parliament passes a law. Payment is denominated in Bitcoin. Settlement is final, permissionless, and outside the reach of any single government or corporation.
Meanwhile, Bitcoin sits at roughly $74,000 as I write this, up about 12% since the war began, with its market cap around $1.33 trillion. Funding rates on Binance’s Bitcoin perpetuals have been negative for 46 consecutive days, even as open interest rises, suggesting persistent bearish positioning and the possibility of a sharp squeeze higher. The $76,000 resistance level, where the mid March rebound rolled over, remains the key level to watch. A decisive break above it, particularly alongside strength in risk assets broadly, would signal the beginning of a more durable move.
