Sanctions do not create one universal way for an oil-exporting country to get paid. A sale may be permitted while restrictions still block or limit the banks, currencies, services, transfers, or uses involved. So a country can receive oil proceeds without being able to freely convert, move, repatriate, or spend them.

The key is to separate three things: the oil sale itself, the transfer and custody of its payment, and what the exporter is legally allowed to do with the proceeds.

What does it mean for a country to be “paid”?

A payment can be credited to an account without being freely available to its owner. The account may be in another country, held in a particular currency, or subject to restrictions that limit transfers or the purchases it can fund. Whether a payment is lawful depends on the transaction and the laws that apply—not just on whether money arrived.

  1. The oil sale: Is the buyer allowed to purchase the oil, and are the seller, goods, and other parties permitted under applicable sanctions?
  2. The payment route and custody: Which banks process the transfer, in what currency, and where are the funds held? A bank’s involvement can create a separate sanctions issue.
  3. Use of the proceeds: Can the exporter convert, transfer, or repatriate the balance, or can it be used only for specified purchases?

These are separate legal questions. A change in invoice currency does not itself make a prohibited transaction lawful, and a payment routed through an intermediary does not automatically remove restrictions.

What arrangements can be used when banking access is limited?

Settlement in a different currency

A buyer and seller may settle in a currency other than dollars or euros. The U.S. Treasury’s Iran-related sanctions release says Iran primarily settles oil sales in Chinese yuan and describes exchange houses and foreign commercial accounts involved in conversion and transfers. That describes a currency and financial network; it does not establish that every payment is permitted or that proceeds are freely accessible.

Intermediary-bank processing

Some transactions may involve a bank that is not itself sanctioned. But the identities of all parties, the reason for the transfer, and the authorization for the underlying transaction still matter. In a Russia-related FAQ, the U.S. Treasury’s Office of Foreign Assets Control (OFAC) says certain authorized transfers to a beneficiary account at a sanctioned institution must be processed indirectly through a non-sanctioned, non-U.S. financial institution. This applies to the particular transfers covered by that guidance; it is not a general route around sanctions.

Restricted or ring-fenced accounts

Under defined conditions, funds can be kept in a foreign account and limited to specified bilateral purchases or humanitarian trade. OFAC’s Iran FAQs describe a bilateral-trade exception and special-purpose accounts for particular statutory arrangements. The permitted account location, eligible purchases, and applicable exception matter; this should not be read as a description of every Iranian oil payment today.

Domestic-currency settlement frameworks

India’s Reserve Bank of India (RBI) rules describe arrangements for rupee payments, including certain transactions through Special Non-Resident Rupee (SNRR) accounts subject to foreign-exchange requirements. Those rules do not, by themselves, prove that a particular oil sale took place through the framework or create an exemption from another country’s sanctions.

How the Iran example shows the difference between receipt and access

Iran illustrates why the currency of a payment and the ability to use it are different questions. Treasury says Iran primarily settles oil sales in yuan, while also describing exchange houses and foreign commercial accounts that facilitate conversion and transfers. The proceeds may therefore be denominated or held in a way that differs from a conventional dollar payment, but that alone does not establish unrestricted access.

For certain statutory exceptions, OFAC guidance describes proceeds held in the jurisdiction of a foreign financial institution and limited to bilateral purchases or humanitarian trade. The details depend on the specific exception and transaction. Separately, Treasury testimony in 2013 described Iranian oil proceeds that generally remained restricted, with limited staged access under the then-current Joint Plan of Action. That testimony is historical and should not be treated as a statement of current rules.

Why Russia’s payment rules and oil price cap are different issues

Russia-related rules illustrate two distinct kinds of restriction. First, OFAC’s FAQ addresses certain transfers involving a beneficiary account at a sanctioned institution: where the specific U.S. authorization applies, the transfer must be processed indirectly through a non-sanctioned, non-U.S. financial institution. The transfer itself must qualify under an applicable authorization; the intermediary does not make an otherwise prohibited transaction permissible.

Second, the Russian oil price-cap framework described in a U.S. Treasury fact sheet dated December 2, 2022, concerned access to specified coalition maritime services, including insurance and trade finance. The fact sheet stated that coalition-country providers could provide those critical services for Russian oil only if it was purchased at or below the cap. It gave $60 per barrel as the then-applicable level for seaborne Russian crude. That is a dated figure, not confirmation of the cap in force in 2026, and the services restriction is not a general account of how all Russian oil payments work.

The December 2022 fact sheet estimated that G7-based firms controlled around 90 percent of relevant maritime insurance and reinsurance at that time. That market-share estimate describes the importance of those service providers to the price-cap design; it is not a measure of banking transfers or blocked payments. A Price Cap Coalition statement in 2024 said Russian tax revenue from oil and petroleum-product exports was 32% lower in January–November 2023 than in January–November 2022. Treasury’s FY 2025 account of Russia energy-sector actions covered more than 180 vessels, oil traders, oilfield service providers, and maritime insurers; that is an enforcement-coverage count, not a count of shipments or blocked payments.

Why the same payment method does not apply everywhere

Sanctions may target different parts of a transaction, under different legal systems. UK guidance, for example, describes prohibitions on processing payments to, from, or via designated persons and on correspondent relationships with designated persons. Separate UK Iran guidance describes account and correspondent restrictions for Iran-connected institutions. These are not the same rules as U.S. authorizations or India’s foreign-exchange arrangements, and none should be treated as a universal sanctions system.

To compare two cases, check which jurisdiction’s rules apply; whether the restriction concerns the exporter, buyer, bank, oil, or service provider; which currency and intermediaries are involved; where funds are held; whether the funds can be transferred or are limited to particular uses; and whether a license, exception, or other authorization covers the transaction. The answer can change with the parties, transaction details, and date.

What the available figures do—and do not—show

The official figures cited here measure different things: insurance-market share, a year-over-year revenue comparison for a defined period, and the entities or vessels covered by enforcement actions. They cannot be combined into a global total for sanctioned oil proceeds received, frozen, held in restricted accounts, or repatriated. No comparable global figure for those balances is established by these sources.
