Iran Oil Sanctions Put China’s Refiners and Banks Under Pressure
China buys most of the Iranian oil that is shipped to other countries.
The United States plans to announce tougher sanctions against Iran on August 24.
Sanctions are rules meant to make it harder for a country to sell goods or use financial systems.
Iranian oil available to Chinese buyers has already decreased.
Some Chinese refineries now have to pay more or search for oil from Brazil and Iraq.
These smaller refineries are important because they often buy discounted Iranian oil.
The United States could punish companies or banks that help move Iranian oil.
China may oppose the sanctions or respond with its own economic pressure.
The situation could make oil more expensive and increase tensions between China and the United States.
China bought more than 80% of Iran’s shipped oil in 2025, according to Kpler data cited by Reuters.
Chinese imports of Iranian oil fell to 534,000 barrels per day in August so far, below the 2025 average of about 1.4 million barrels per day.
Reduced availability has pushed some Iranian crude from discounts to premiums of about $2 per barrel over ICE Brent.
Chinese independent refineries are considering Brazilian Lapa and Iraqi Basrah crude as alternatives.
The United States is preparing new sanctions that could target companies, traders, financial channels or banks involved in Iran’s oil trade.
- Who
- The United States, China, Iran, Chinese independent refineries and financial institutions involved in the oil trade.
- What
- Washington is preparing another round of sanctions against Iran, while reduced Iranian oil availability is pressuring Chinese buyers to seek alternatives.
- Where
- The effects are centered on the China-Iran oil trade, with about 40 million barrels reportedly held on ships in Malaysian waters east of Singapore.
- When
- Scott Bessent announced the planned sanctions details on August 20, with further details expected on August 24; the cited trade data is from 2025.
- Why
- The United States aims to disrupt Iran’s oil revenue and sanction networks supporting its oil exports, while China seeks to maintain supplies for its refineries.

Potential bank sanctions

Washington may use secondary sanctions to restrict companies and banks that help process Iranian oil transactions or funds.

Sanctioning major Chinese banks could affect transactions beyond the Iran trade and provoke a stronger response from Beijing.

China may need to buy more expensive or less attractive crude from countries such as Brazil and Iraq, while retaining leverage through trade and critical-mineral supply chains.
