On July 21, PetroChina fell 3.2% in regular trading, trading at HK$9.68 with turnover of HK$394 million. The three major Chinese oil majors declined collectively, with CNOOC dropping nearly 3% and Sinopec falling about 1%.

On the news front, US-Iran tensions showed signs of easing after a senior Iranian official disclosed that a mediator had proposed a 10-day ceasefire aimed at de-escalating the current situation and restoring the memorandum of understanding reached between the two sides last month. In response, Brent crude fell nearly $0.5 during the Asian morning session, dropping below $87 per barrel with a daily decline of approximately 0.58%.

The oil price retreat marks a reversal from recent strength driven by escalating US-Iran conflict, which had previously pushed Brent above $84 per barrel with New York crude surging as much as 9.4% in a single session. The ceasefire proposal has cooled market expectations of supply disruption, pressuring oil prices and triggering a broad pullback in petroleum equities.
