US equity markets closed lower on Thursday, with the S&P 500 and Dow Jones Industrial Average retreating from recent highs as rising oil prices weighed on investor sentiment.
The sell-off marked a sharp reversal from earlier in the week, when optimism surrounding potential diplomatic progress between the United States and Iran had fueled a broad rally and pushed US benchmarks to record levels.
Brent crude prices climbed during the session, erasing the approximately 4% drop from midnight levels that had occurred as traders priced in a possible agreement to reopen the Strait of Hormuz.
