The U.S. decision to replace the Iran General License X with X1 on July 7 has effectively halted new purchases and loadings of Iranian crude, allowing only wind-down trades until July 17. This abrupt policy shift has left approximately 63 million barrels of Iranian oil floating on tankers, with no clear buyers, as China's refiners pause their imports.
Impact on Chinese Refiners
China Petroleum & Chemical Corp (Sinopec) and PetroChina Co Ltd have been evaluating shipping, insurance, and payment options to resume Iranian crude imports once a waiver is in place. However, with the waiver now terminated, these plans are on hold. Independent teapot refineries, the primary buyers of Iranian oil, face uncertainty as new purchases are banned. Iranian crude loadings had surged to about 1.6 million barrels per day between June 19 and June 24, up from 340,000 barrels per day earlier in June, but that flow is now threatened.
Market Reaction and Supply Risks
Brent crude rose 5.14% to trade at $77.97 a barrel by 1339 GMT, with the three-month Brent spread moving to $2.36 in backwardation, signaling tighter short-term supply. The floating Iranian barrels—worth roughly $4.9 billion at current prices—represent about 40 days of China-bound Iranian crude and condensate flows, based on 2025 EIA data showing Iran shipped 1.576 million barrels per day, nearly all to China.
Shipping and Geopolitical Tensions
Beyond Iranian barrels, shipping data indicate heightened risk premiums. At least four oil and gas tankers avoided Hormuz transits after recent vessel attacks. The Indian-flagged VLCC Lila Vadinar, carrying 2 million barrels of Kuwaiti crude, turned back off Oman. Mangalore Refinery and Petrochemicals Ltd dropped its Iraqi crude charter. These disruptions add to supply concerns.
Strategic Reserves and Market Outlook
With global inventories drawn down—around 1 billion barrels released from reserves during the supply shock, including 400 million from the IEA—the floating Iranian barrels are more critical than headline numbers suggest. Bob McNally of Rapidan Energy Group noted that the latest developments indicate the ceasefire is less solid than assumed, adding that the oil market has risk pricing to do. John Baffes of the World Bank described the disruption as serious but manageable, while Ilia Bouchouev of the Oxford Institute for Energy Studies warned that thinner buffers could lead to sharper price spikes.
Broader Implications
China's refiners are also cutting refined fuel exports for July, with Zhejiang Petrochemical Co resuming exports after a three-month hiatus. The broader market context suggests that each $5 move in oil adds about $190 billion annually to global costs. As traders assess the impact, the floating Iranian barrels remain a key variable in the near-term supply outlook.
