US stocks experienced a decline on Monday as rising oil prices and increased Treasury yields fueled worries about inflation and borrowing costs. The S&P 500 dropped by 0.6%, the Dow Jones Industrial Average fell 0.4%, and the Nasdaq Composite also decreased by 0.6%. This downturn occurred as Brent crude oil prices briefly surged above $100 per barrel before settling around $97.61.
The volatility in oil prices is largely attributed to uncertainties surrounding the flow of tankers through the Strait of Hormuz amid ongoing conflicts involving Iran. The spike in energy prices has intensified concerns over inflation, with US gasoline prices having risen significantly over the past year.
In response to these inflation worries, Treasury yields saw an increase. The yield on the 10-year Treasury note rose to 5.24% from 5.17%, while the 30-year Treasury yield climbed to 5.56%. Higher borrowing costs can exert pressure on both businesses and consumers, potentially reducing the attractiveness of stocks and other investments.
Airline stocks were notably affected, as investors evaluated the impact of increased fuel costs on the industry. Both American Airlines and United Airlines reported losses. Additionally, gold-related stocks weakened, reflecting a sharp decline in gold prices during the trading session.
