Iran has reportedly used a barter-like financing system to turn oil sales to China into credits for Chinese goods while reducing exposure to the conventional international banking system. Reuters estimates that $2 billion to $2.5 billion passed through a special-purpose vehicle during the past year, based on accounts from Iranian officials and other people familiar with the arrangement.
The reported mechanism does not involve a simple ship-for-shipment swap. Instead, money connected with Iranian oil is placed into a controlled structure and converted into purchasing credit. Iranian buyers can then use that credit to obtain approved goods from Chinese suppliers without a normal cross-border payment moving directly from an Iranian bank.
China's foreign ministry told Reuters it was not familiar with the arrangement described. Iran's missions to the United Nations did not respond, and several claims—including reported transactions involving military equipment—could not be independently verified by Reuters. Those limitations are essential when assessing the report.
How the reported oil-for-goods arrangement works
The system can be understood in five stages:
- Iranian oil is sold into China through channels able to handle sanctioned trade.
- A China-based entity deposits value connected with those purchases into a special-purpose vehicle.
- Iran receives credits rather than freely transferable dollars.
- Iranian importers select Chinese goods that can be paid for through the structure.
- Suppliers receive local or protected payment without directly handling an obvious Iranian bank transfer.
This design gives each participant a degree of separation. Iran obtains useful imports, China continues buying discounted oil and manufacturers can be paid without necessarily entering a direct financial relationship with Iran.
Reuters reported that the mechanism has been operating since at least 2021. About 70% of the proceeds were directed toward infrastructure projects in Iran, while the remainder supported purchases such as medicines, vehicles and communications equipment.
Why normal banking channels are difficult for Iran
US sanctions can reach beyond American companies because much of global trade uses the dollar or passes through banks that need access to the US financial system. A foreign institution may avoid an Iranian transaction even when its own government does not prohibit the trade, fearing penalties or the loss of dollar clearing.
That creates an incentive to keep payments inside a local network. Credits that cannot easily leave China are less flexible than cash, but they can still be valuable if Iran needs Chinese construction services, industrial equipment and consumer goods.
The arrangement also resembles countertrade systems used by sanctioned countries in earlier periods. The technology and corporate structure may be modern, but the principle is old: exchange an export for restricted purchasing power rather than settle through a universally accepted currency.
What Iran reportedly bought
Sources told Reuters that the system funded medicine, vehicles and communications equipment. They also said it was used at least once during the past year in connection with contracts for air-defence equipment worth millions of dollars.
Reuters could not independently verify those military transactions, and the manufacturers were not described as dealing directly with Iran. There was no indication in the report that Chinese companies supplying ordinary goods had knowingly violated sanctions.
That difference matters legally. A payment mechanism may be designed to reduce scrutiny, but responsibility depends on the product, parties, knowledge and specific sanctions rules involved. Medicine and many humanitarian goods may be exempt or permitted even when banking obstacles make payment difficult.
Why China benefits
China is the world's largest crude importer and can gain access to Iranian oil at discounted prices. A credit-based structure also keeps much of the spending inside China because Iran must use the proceeds on Chinese goods or projects rather than move the money elsewhere.
At the same time, Beijing wants to limit the risk that major banks and exporters become targets of US penalties. Smaller traders, indirect ownership structures, local-currency settlement and special-purpose entities can insulate strategically important institutions, though they cannot remove all risk.
China and Iran both reject unilateral Western sanctions that they consider unsupported by international law. The United States argues that financial pressure is necessary to restrict Iran's nuclear and military capabilities.
What changed after the Strait of Hormuz blockade
The report comes during a more severe conflict environment. Washington has intensified pressure on Iran and sought to reopen the Strait of Hormuz, while a naval blockade has restricted Iranian crude shipments through the waterway.
Reuters said it could not determine how the blockade affected the credit mechanism. If physical oil cargoes cannot reach China, the flow of new credits would eventually become harder to sustain. Previously accumulated balances and trade routed through alternative channels could still support purchases for a period.

What happens next
US authorities could target the special-purpose vehicle, intermediary companies, insurers or shipping networks if they obtain evidence identifying the participants. Enforcement is difficult when ownership changes quickly and transactions remain outside dollar banking.
China must also balance competing interests: securing energy, supporting a strategic partner and protecting major domestic institutions from secondary sanctions. Iran, meanwhile, receives vital imports but sacrifices control because credits tied to China cannot be spent as freely as cash.
The reported system shows why sanctions rarely create a complete economic seal. They raise cost, reduce choice and force trade into less transparent channels. Whether that pressure changes government policy is a separate question—and one that depends on enforcement, diplomacy and the availability of partners willing to keep commerce moving.
