Investors are concerned about the bearish sentiment on the supply side as crude oil prices continue to fall in the past few days. The concerns are mainly due to two factors: first, market expectations of an increase in crude oil production in the usa after the elections, and second, the gradual shift from the Saudi-led production cut action to an increase starting next year, leading to worries that the two will compete for market share. Under such concerns about increased production, crude oil prices continue to decline. Zhuochuang News forecasts that the bearish sentiment on the supply side is dominant, with the demand side in a seasonal off-peak period, strong expectations of oil inventory accumulation, a strengthening US dollar, and multiple bearish factors. As a result, US crude oil broke below the key level of $70, lacking short-term bullish drivers, maintaining a weak market sentiment.
