Oil prices experienced an increase on Monday, influenced by heightened geopolitical tensions surrounding the Strait of Hormuz. The trading environment was quiet in U.S. markets as investors observed the Labor Day holiday.

Futures contracts for U.S. crude oil saw a rise, reflecting concerns over potential supply disruptions in the vital waterway, a key transit route for a significant portion of global oil supply. This geopolitical development overshadowed the subdued trading activity typical of U.S. financial markets on a federal holiday.

Treasury markets also remained closed for the holiday, contributing to the lack of significant movement in U.S. fixed-income securities. The combination of external geopolitical factors and the domestic holiday closure led to a market characterized by limited trading volume and a focus on energy supply security.
