CNOOC's stock price plummeted 5.26% in early trading on Wednesday, mirroring a broad decline across the energy sector.
The sharp drop follows news of a significant de-escalation in Middle East tensions. A former US President announced acceptance of a two-week ceasefire proposal mediated by Pakistan, a move also accepted by Israel and Iran. Iranian officials confirmed that Iran-US negotiations are scheduled to begin this Friday in Islamabad.
In response to the geopolitical developments, international oil prices continued their steep decline, with WTI crude oil futures briefly crashing over 19%. The ceasefire agreement, which took effect in the early hours of Wednesday, has alleviated supply disruption concerns, directly pressuring the shares of major oil producers like CNOOC.
