European and American crude oil futures rose narrowly on Tuesday. Market expectations of last week's decline in U.S. crude oil inventories helped oil prices reverse their intraday decline in late trading, but trade tensions still threatened the performance of crude oil demand, limiting upward space for oil prices. U.S. oil companies have begun to reduce the construction of new drilling, turning their attention to profit growth rather than production growth. Kuwait said that the current reduction is much higher than the promised scale. Saudi Arabia also said it would continue to restrict crude oil exports, thereby reducing the level of oversupply. Nevertheless, the growing signs of a global economic slowdown and trade tensions have made the outlook for crude oil demand pessimistic.

As of August 20, WTI was up 0.13 to 56.34 and Brent was up 0.29 to 60.03 dollars per barrel. SC main force rose 6.7 to 425.4 yuan per barrel in 1910.
