Oil prices reverse gains in Strait of Hormuz standoff as Wall Street inches up ahead of inflation numbers

Wall Street experienced modest declines in premarket trading, with oil prices fluctuating amid uncertainty over the Strait of Hormuz's reopening. While S&P 500 futures rose 0.1%, Dow Jones futures dropped 0.1%, and Nasdaq futures increased by 0.3%. Oil prices, once up about 2.5%, reversed course and fell slightly, reaching $87.61 a barrel for Brent crude and $82.19 for U.S. benchmark crude.

Major U.S. oil companies saw shares near unchanged levels, having surged 4.5% the previous day. Oil prices swung between $72 and $102 last month, with hopes for a U.S.-Iran agreement fluctuating. Gas prices, averaging above $4 a gallon in the U.S., were expected to rise further. The following Wednesday's update on U.S. inflation in July would be the main focus of Wall Street as economists predicted a slowdown to 3.4% from June's 3.5%.

Higher interest rates could help curb inflation but might slow the economy, impacting stocks and investments. Global markets saw mixed performance, with European indices slightly lower, and Asian markets fluctuating after a slight decline on Wall Street.
