Wall Street Gains as Oil Prices Cool and Stocks Respond
On Monday, September 14, 2026, stocks on Wall Street experienced positive momentum due to a decrease in oil prices. This relief allowed U.S. stocks to achieve their first winning week in the last three weeks. The S&P 500 broke a three-day losing streak by gaining 0.5%, despite fluctuations caused by rising bond market yields. The index approached within 0.7% of its all-time high recorded the previous month.
The Dow Jones Industrial Average rose by 478 points, or 0.9%, and the Nasdaq composite increased by 0.5%. A major factor in this upward trend was the decline in Brent crude oil prices, which fell by 2.8%, settling at $97.44 per barrel. These fluctuations in oil prices are influenced by uncertainty regarding the ongoing war with Iran and its impact on Middle Eastern oil flow. Prices drop when optimism grows for a possible agreement to reopen the Strait of Hormuz to oil tankers, yet surge when doubt arises.
Friday’s stock trading was unpredictable due to a report on U.S. consumer sentiment that temporarily pushed Treasury yields up in the morning. The University of Michigan’s report suggested U.S. consumers are anticipating a 4.6% inflation rate for the coming year, a rise from the previous forecast of 4%. Although consumer sentiment was less dire than economists predicted, it marked a four-month low. Higher inflation expectations can drive economic behaviors that potentially lead to further increases in living costs.
Some consumers revealed in the survey their belief that purchasing certain items now might help them avoid higher prices later. Such actions, if widespread, could prompt sellers to further increase prices.
After the sentiment report, the yield on the 10-year Treasury briefly climbed to 5.22%, up from 5.18% on Thursday, nearing its highest mark since 2007. Increased yields can slow the economy by making borrowing costs higher and destabilizing stock and investment prices. Yields have been rising since the onset of the Iran war when they were at 3.97%. Various worries, including inflation, expensive oil, and large government debts, contribute to this global yield escalation.
Latter trading hours saw yields ease, coinciding with the decrease in oil prices, aiding Wall Street’s stock recovery. Akamai Technologies played a significant role in boosting the market, with its shares rising 3.2% following the announcement of an $11.6 billion deal with Anthropic, the company behind the Claude AI chatbot. Costco Wholesale also surged by 2.9%, surpassing analysts’ profit expectations for its latest quarter. Such robust profit reports from U.S. companies bolster the stock market amid inflation and oil price concerns.
The S&P 500 closed up 39.28 points at 7,743.41. The Dow Jones Industrial Average leaped 478.64 points to 51,828.62, while the Nasdaq composite grew by 129.34 points, reaching 27,068.72. Global stock markets showed mixed results, with Europe’s indexes fluctuating following larger moves in Asia. Japan’s Nikkei 225 increased by 1.3%, contrasting with a 1% drop in Hong Kong’s Hang Seng.
