OPEC+ countries have announced voluntary production cuts of 219.3 million barrels per day in the first quarter of next year. However, doubts remain over the commitment of oil-producing countries to the cuts, leaving the market disappointed and prices continue to fall. Adding to this, global economic data is not looking promising. It is suggested that short positions on crude oil should continue to be held cautiously. With the inclusion of US oil in the Brent crude pricing system, the global pricing power is gradually shifting towards light oil. Despite the additional cuts by OPEC+, the fundamental structure of light oil accumulation in the first quarter of next year is unlikely to change, and the downward trend in oil prices may become a reality. （责任编辑:董萍萍）
