What happened

US stock markets fell on [date], with the Dow Jones Industrial Average, S&P 500, and Nasdaq Composite all posting losses.

Oil price pressure

Rising crude oil prices, driven by supply worries, added to inflation fears and weighed on broader market indices, particularly impacting transportation and consumer stocks.
