Iran Oil Tanker Fees Still Dominated by USDt, No Signs of BTC Yet: BPI

BPI says Iran oil tanker fees USDt flows still dominate settlement around Strait of Hormuz toll collections, while public blockchain evidence still does not show Bitcoin moving at tanker-payment scale.

What BPI says the data supports

The Bitcoin Policy Institute wrote that the settlement layer is almost entirely USDT on Tron and said public onchain data has not shown bitcoin moving at the size needed for tanker-fee payments. It also said Iran's parliament approved the Strait of Hormuz Management Plan on March 30, 2026, formalizing a toll framework around the chokepoint.

That claim is narrower than a statement about all Iranian trade. BPI is describing tanker-fee settlement around the strait, and its BTC caution is framed as a judgment about current public evidence rather than a permanent conclusion about Bitcoin.

Why the settlement rail matters more than the narrative

TRM Labs said public estimates put potential oil-tanker toll revenue at up to USD 20 million per day, which is why analysts are looking for visible settlement rails rather than symbolic crypto messaging.

TRM also said Iranian state media and some officials pointed to bitcoin, but Western reporting indicates USDT is what the IRGC collects in practice, and the full bill text has not been published. No public wallet addresses or transaction set have been identified that prove a live bitcoin tanker-toll payment.

TRM said the toll for a fully loaded very large crude carrier can reach about USD 2 million. BPI's finding that public bitcoin flows have not appeared at that size supports the idea that counterparties still prefer a dollar-pegged unit for operational invoices.

That makes this a different question from the market reaction covered in Bitcoin Tops $76K as Iran Declares Strait of Hormuz Open. The story here is about settlement plumbing, not fresh proof that Bitcoin is already clearing tanker tolls.

Stablecoin evidence extends beyond one shipping corridor

BPI estimated Iran's broader IRGC-linked crypto activity at roughly USD 3 billion since 2023, and it described the current settlement layer as overwhelmingly stablecoin-based. That turns the tanker-fee story into part of a larger sanctions-evasion payments pattern rather than a one-off anecdote.

Elliptic said the Central Bank of Iran acquired at least USD 507 million in USDT, with flows shifting to a cross-chain bridge after June 2025. That data strengthens the case that state-linked actors have built more visible capacity around stablecoin rails than around public Bitcoin settlement for recurring bills.

Against Elliptic's USD 507 million USDT figure, the gap between reserve-asset narratives and payment usage looks closer to the treasury behavior discussed in Bitcoin Mining Companies Sold More BTC in Q1 2026 Than 2025. Bitcoin can matter as a balance-sheet asset even while USDt dominates invoices.

Why Bitcoin's strategic case is still part of the debate

The lack of confirmed tanker-scale BTC transfers does not erase Bitcoin's strategic appeal for some policy advocates. Sam Lyman argued in comments cited by Cointelegraph that the Hormuz episode still shows why Bitcoin matters strategically, even if the observable settlement evidence currently points elsewhere.

"This is one of the most significant situations where Bitcoin is very clearly a strategic asset."

In a January 30, 2026 action that Treasury said was OFAC's first designation of an IRGC-linked digital asset exchange, the agency named Zedcex and Zedxion and said Zedcex had processed more than USD 94 billion in transactions. That enforcement backdrop matters because the stablecoin-heavy corridors described by BPI, TRM and Elliptic are also the ones US authorities are now targeting more directly.

BPI's USDT-on-Tron finding, together with Elliptic's USD 507 million USDT figure, helps explain why this payment-rail story may matter more operationally than governance headlines such as Josh Stark Announces Departure From the Ethereum Foundation. One story is about settlement capacity, the other about leadership, but the stablecoin data is what directly informs the tanker-fee claim.

The practical takeaway is two-sided. BPI and TRM point to USDt as the current tool for tanker-fee settlement, while the strategic case for Bitcoin remains alive precisely because the public evidence set is still incomplete and the full statute text has not been independently checked in the available materials.
