Iran successfully rushed around 70 million barrels of crude oil to Chinese buyers, earning about $6 billion in a very short time. This massive sales push happened during a brief two-week break when the United States temporarily lifted its trade bans, according to a report by The Wall Street Journal.
The sudden burst of shipping followed a short-lived diplomatic agreement signed on 17 June. Under this deal, Washington paused its strict rules on Iranian oil, giving the country a brief window to trade openly. However, after fresh military tensions broke out in the region, the US reinstated the trade bans on 7 July, closing the trade window.
Data from energy tracking groups shows that almost all of this oil was moved in the second half of June. In just 13 days—between 17 June and 30 June—millions of barrels of oil arrived at Chinese ports and regional shipping hubs.
The shipping secret: moving oil at sea
To pull off this massive sale so quickly, Iran used a fleet of about 20 enormous oil tankers. These ships loaded up fast at major Iranian ports and sailed straight toward Southeast Asia.
Instead of sailing directly into mainland China, the Iranian tankers met in an offshore area known as the Eastern Outer Port Limits (EOPL). This is a busy water zone located just outside Malaysia’s borders that is popular for moving fuel between ships. Once there, the Iranian tankers used large, flexible pipes to pump their oil onto other waiting ships. This clever method helps smaller, independent Chinese refineries buy the discounted oil through indirect pathways.
What this means for the market
Even though the US has tried to block Iran from selling oil since 1979, China has consistently been Iran’s most reliable customer, buying nearly 90% of its exported oil. This recent $6 billion payout gives Iran a helpful financial boost just as strict Western trade limits return.
Now that the temporary break has ended and the US restrictions are active again, the pressure on Iran’s shipping system will grow. The new rules target not only the oil tankers themselves, but also the ports and banking networks that handle the money.
For the everyday oil market, this sudden stop-and-start trading creates a lot of uncertainty. With tensions remaining high along major Middle Eastern shipping routes, experts warn that these constant interruptions could cause global oil prices to jump up and down, driving up fuel costs for countries around the world.
