Oil Prices Respond to U.S.–Iran Talks and China’s Market Influence

Global oil benchmarks slipped after the first round of U.S.–Iran negotiations in Switzerland. Brent crude fell to about $79 per barrel and West Texas Intermediate to $75 per barrel, reversing earlier gains that had pushed Brent above $82. The price movement coincided with reports that the Strait of Hormuz—through which roughly one-fifth of world oil flows—could reopen under a memorandum of understanding that extends a cease-fire for 60 days.

The conflict that began on 28 February 2026 halted oil shipments through the Strait, cutting off more than 11 million barrels per day (about 14 % of global supply). Analysts note that total estimated supply losses have exceeded 1 billion barrels, yet price spikes have been muted. The reopening of the waterway is central to market expectations of a supply rebound.

U.S. officials described the talks as providing “a good foundation for a successful final deal.” Iranian representatives emphasized the need to address proxy activity in Lebanon before broader agreements. Qatar and Pakistan, acting as mediators, issued a joint statement noting “encouraging progress.” The International Energy Agency highlighted the risk of a supply glut once the Strait fully reopens, while Chinese authorities pointed to reserve releases and export limits on refined products as market-stabilizing measures.

Analysts warn that China’s stockpiles are finite and that a rapid reopening could inject 100 million barrels of stranded oil, stressing the market. Trump’s threat to levy U.S. tolls on Hormuz traffic and to resume military action has been cited as a destabilizing factor. Some observers question the durability of the cease-fire, noting divergent claims about whether the Strait remains closed.

U.S. Central Command reported continued vessel traffic, whereas Iranian officials announced a closure of the Strait on the same day. Supply-loss estimates range from “more than 1 billion barrels” to “100 million barrels of stranded oil,” reflecting uncertainty about the timing and magnitude of any rebound.

The IEA expects a potential oversupply of 4.7 million bpd in 2027, contingent on the speed of Hormuz reopening and China’s willingness to absorb excess crude. Continued negotiations will determine the final terms for vessel traffic, sanctions relief, and Iranian oil exports. Simultaneously, China’s expanding EV sector and renewable-technology exports may further reduce global oil demand, shaping the longer-term trajectory of crude markets.
