On June 18, Sinopec Corp (00386.HK) fell 3.06% in regular trading, trading at HKD 4.12/share, with turnover of HKD 371 million. PetroChina declined 3.31% simultaneously, reflecting broad sector pressure.

On the news front, the US and Iran reached a preliminary peace agreement, with both sides announcing an immediate permanent cessation of military operations across all fronts. The formal signing ceremony is scheduled for June 19 in Switzerland. Market expectations for the reopening of the Strait of Hormuz have surged, accelerating the unwinding of geopolitical risk premiums embedded in crude oil prices. Brent crude futures fell below USD 83 per barrel, having dropped approximately 4.65% since the agreement was confirmed on June 15.

Analysts estimate that the prior geopolitical premium of roughly USD 20 per barrel will be progressively unwound, with oil prices potentially finding support near USD 78-80 per barrel. For Sinopec, while lower oil prices are structurally favorable to its refining-dominated business model over the medium term, the near-term rapid decline in crude benchmarks has weighed on sector valuations and triggered broad selling across integrated oil and gas names.
