Stock markets struggling to keep up with rising oil prices and bond yields

Rising oil prices are causing U.S. stock markets to struggle to maintain their record highs, while adding pressure to the U.S. bond market. The S&P 500 experienced a decline of 0.8%, and both the Dow Jones Industrial Average and the Nasdaq composite were down 0.7% and 1%, respectively, as of 11:45 a.m. Eastern time. The steep increase in oil prices, reaching $100.19 per barrel, was driven by uncertainty surrounding the ongoing war with Iran and its potential impact on the Strait of Hormuz.

This surge in oil costs, which began at $72 a barrel before the recent conflict, has contributed to inflation and led to higher yields on U.S. Treasury bonds, making borrowing more expensive for both the economy and investors. Companies with significant fuel expenses, such as airlines, suffered losses, including American Airlines and United Airlines, which fell by 3.8% and 3.6%, respectively.

Meanwhile, gold miners faced declines due to the weakening gold price and the higher yields on bonds, as gold typically acts as a hedge against inflation but struggles when interest rates rise. Notable losses were seen in MongoDB, which dropped 18.5%, following the CEO's sudden resignation. Despite these setbacks, Nvidia's stock rebounded after announcing a $150 billion stock buyback plan, bringing its total remaining size to $235 billion.
