In this article, we are going to discuss the energy stocks that are losing this week.
The global oil and gas sector has experienced a volatile few weeks following concerns regarding global oversupply and US demand, as well as the recent drone attack by Kyiv that suspended loadings from the largest port in western Russia. Overall, the WTI (West Texas Intermediate) crude oil price gained by around 1.3% between September 5 and September 12, 2025.
However, the American oil industry continues to face a bleak outlook, as the recent Texas labor market statistics revealed that the country’s oil and gas production jobs fell by 4,700 in the first six months of this year. Notably, ConocoPhillips, America’s third-largest oil producer, announced recently that it would cut up to 25% of its staff. This comes after a similar announcement by Chevron earlier this year, when the oil behemoth revealed that it would slash a fifth of its workforce.
