On July 3, CNOOC rose 3.24% in regular trading, trading at HK$21.1/share, with turnover of HK$348 million.

On the news front, senior Iranian sources revealed that Iran is determined to seek international recognition of its control over the Strait of Hormuz and the right to levy fees on vessels transiting the Gulf, even if force is required. The hardline statement reversed market optimism regarding supply recovery, reigniting geopolitical risk premiums across the oil sector.

The development marks a sharp pivot from late June when Hormuz Strait traffic had rebounded significantly and oil prices had retraced gains accumulated during earlier Middle East tensions. Iran's latest posture effectively unwound those easing expectations, driving a broad rebound in petroleum stocks. Within the Oil and Gas Exploration and Production sector, United Energy Group rose 2.99%, CHK Oil gained 3.75%, and China Energy added 1.61%.
