Stocks Plummet as Oil Prices Climb Amid Ongoing Global Tensions

The stock market experienced a downturn on Tuesday, September 1, as oil prices continued to rise. The S&P 500 index fell by 0.7%, while the Dow Jones Industrial Average dropped by 456 points or 0.9%. The Nasdaq composite also fell by 1%.

The weak start to September follows a shaky but mostly positive month for Wall Street in August, where every major index notched monthly gains. However, ongoing worries about rising prices, government debt, and the impact of global conflicts on the U.S. and the global economy continue to weigh heavily on investors' minds.

The technology sector took a hit, with Microsoft falling by 1.3% and Advanced Micro Devices dropping by 3%. The big market values of these companies tend to give them more influence over the broader market's direction, and their growth has been heavily reliant on borrowing, which becomes more expensive as interest rates rise.

The yield on the 10-year Treasury rose to 4.79% from 4.75% late Monday, while the yield on the 2-year Treasury rose to 4.38% from 4.34% late Monday. Rising yields signal that investors are demanding a higher return from Treasurys because they are becoming riskier, and growing government debt is highlighting this risk.

The U.S. debt surpassed $40 trillion two weeks ago, making up an enormous share of federal spending in the form of defense costs and interest on the burgeoning deficit. Higher yields on bonds signal higher borrowing costs on mortgages and a wide range of other loans, which can weigh down investments and make it more difficult for businesses to expand.

Oil prices have been behind much of the pressure on inflation, bond yields, and the broader stock market. The price of Brent crude rose by 3.9% to $94, and energy costs remain high and volatile amid the ongoing U.S. war with Iran, which has essentially shut down the Strait of Hormuz.
