Sellers of Iranian crude to China have substantially decreased prices after the Islamic Republic increased its oil shipments following an interim peace deal with the US. Traders and middlemen are offering spot cargoes of Iranian Light crude for July delivery at a discount of $2.50 to $5 a barrel compared to Brent benchmark prices. This is a considerable increase from the approximately $1 discount offered before the deal.

Iran has significantly boosted the amount of oil it is openly sending through the Strait of Hormuz, reaching the highest levels since the war began. This surge in shipping activity coincides with ongoing efforts by Tehran and Washington to secure a lasting peace deal. Tracking data indicates that about 6 million barrels are currently on three US-sanctioned supertankers—Elva, Virgo, and Vigor—that entered the strait recently. These vessels are reportedly headed for waters off Singapore, a common transfer point for Iranian crude destined for China.

The United States temporarily suspended sanctions on Iranian oil after Vice President JD Vance announced that Iran would allow UN nuclear inspectors back into the country, following discussions in Switzerland. The US Treasury confirmed the temporary lifting of sanctions to permit Iran to produce, sell, and deliver crude oil and related products through August 21. Treasury Secretary Scott Bessent cited Tehran's commitment to "free and open transit" in the Strait of Hormuz and permission for International Atomic Energy Agency (IAEA) inspectors as key reasons for this pause in sanctions.

Mediators Pakistan and Qatar have revealed that negotiators reached an agreement on a "roadmap towards reaching a final deal within 60 days," with technical talks continuing for the rest of the week in Switzerland. Iran's Foreign Minister Abbas Araghchi stated that "Oil and petrochem exports are waived, blockade lifted, some frozen assets released, and major reconstruction & development plan launched for Iran." The broader provisions of the US-Iran understanding are set to take effect only once a final settlement to end the war in Lebanon is reached.

This development provides a brief window for Iranian oil imports, driven by the interim peace agreement and the temporary suspension of US sanctions. The increased supply and attractive discounts are likely to influence global oil markets, particularly impacting China, which is a major recipient of Iranian crude after transfers in places like Singapore.
