Oil prices have surged past $90 per barrel, a level not seen in the last 10 months, due to an improving global demand outlook and tightening supplies. This has resulted in a 30% increase in the U.S. oil benchmark over the past three months. Factors contributing to the surge include stronger-than-expected U.S. economic data, China's stimulus measures, and the prospect of central banks ending their tightening campaigns. On the supply side, oil producers are extending production cuts and oil inventories are at historically low levels. Several U.S. oil-related stocks show varying degrees of sensitivity to these oil price fluctuations.
