HSBC Global Research has issued a report predicting that earnings in the oil sector will nosedive in 2Q25, given that oil prices have already fallen by about 20% QTD. The broker estimated Brent crude prices to range US$65-67 per barrel from 2Q to 4Q in 2025, but the accelerated unwinding of production cuts by OPEC+ and other macro risks (such as global trade tensions) could pose further downside risks.In HSBC Global Research's opinion, for every US$10/ barrel decline in Brent crude prices this year, CNOOC (00883.HK) +0.260 (+1.503%) Short selling $32.85M; Ratio 5.594% will see its earnings wane by 16%/ 25% in 2025/ 2026 as it is the most sensitive to upstream exploration and production. Nevertheless, the broker kept a Buy rating on it in light of its low unit production costs and balance sheet at net-cash, which allows it to generate positive cash flow even in a low oil price environment. The target price for CNOOC's H-shares was lowered from $21 to $19.4.Related NewsBOCI Lists Top 10 HK Stocks by Southbound Trading Net Inflows from 1 Apr to 9 May (Table)Among the three Chinese oil giants, HSBC Global Research continued to favor PETROCHINA (00857.HK) +0.050 (+0.804%) Short selling $16.51M; Ratio 8.308% because of structural improvements in its natural gas business and operational efficiency, which have enhanced the quality of its free cash flow, with a dividend yield expected to reach 7.5%.
