Wall Street between the AI rally and rising bond yields
Wall Street closed the week higher, driven by artificial intelligence. But Treasury yields topped 5% and oil climbed again. What weighs more now: the excitement or the rates?
Wall Street ended the week with gains across its major indexes after several days of volatility driven by enthusiasm around artificial intelligence, rising Treasury yields, and geopolitical uncertainty.
Although technology stocks helped recover some of their losses, interest rates and oil prices continued to influence investor sentiment.
The Nasdaq Composite gained approximately 1.3% for the week, while the S&P 500 rose around 0.5% and the Dow Jones gained about 0.1%. The positive results came after all three indexes faced pressure from higher financing costs and concerns about inflation.
Artificial Intelligence gives the Nasdaq another boost
Technology stocks were among the market’s main drivers. On Monday, the Nasdaq rose 2.3% and reached a record closing high, supported by semiconductor companies and growth expectations surrounding artificial intelligence.
Advanced Micro Devices (AMD) stood out as its shares rose approximately 10%, pushing its market capitalization above US$1 trillion for the first time. Intel and Arm Holdings also posted significant gains, reinforcing investor interest in the semiconductor sector.
However, the momentum weakened in the middle of the week. Concerns about interest rates and technology stock valuations triggered further declines, showing that enthusiasm for AI continues to coexist with greater caution over financing costs.
Bond yields put pressure on the market again
One of the main sources of pressure was the rise in U.S. Treasury yields. The 10-year Treasury yield moved above 5% and approached 5.2%, reaching levels not seen since 2007.
The move reflected expectations that interest rates could remain elevated for longer, as well as economic indicators pointing to continued resilience in the U.S. economy.
When bond yields rise, fixed-income investments can become more attractive compared with stocks. Higher rates also make borrowing more expensive for businesses and consumers, potentially affecting investment decisions and economic growth.
Technology companies tend to be particularly sensitive to these movements because a significant portion of their valuations depend on profits they expect to generate in the future.
Oil prices and Middle East tensions remain in focus
Oil prices once again moved above US$100 per barrel during the week as tensions between the United States and Iran heightened concerns about energy supplies.
However, Brent crude had fallen below US$100 on Monday amid expectations of diplomatic progress. On Friday, reports of a possible reopening of the Strait of Hormuz helped moderate prices and provided some relief to markets.
Oil prices matter because they directly affect transportation and production costs and can eventually influence consumer prices. If oil remains expensive, inflation could take longer to cool, complicating the Federal Reserve’s policy decisions.
The United States and China remain on investors’ radar
Trade relations between Washington and Beijing also remained relevant to the market. Talks between Donald Trump and Xi Jinping kept tariffs, technology, and trade conditions between the world’s two largest economies in focus.
For technology companies and semiconductor manufacturers, any changes to trade restrictions can affect sales, costs, and supply chains.
Investors will continue watching for signs of cooperation or renewed tensions, particularly as companies seek greater clarity to plan their investments.
Inflation will be the market’s next test
This week, attention will turn to new U.S. economic indicators, particularly the Personal Consumption Expenditures (PCE) price index, scheduled for release on September 30. This is one of the Federal Reserve’s main inflation gauges.
The data will help investors assess whether price pressures remain persistent and how much room the central bank may have to adjust interest rates in the coming months.
Persistent inflation could keep bond yields under pressure, while signs of easing price pressures could help improve investor sentiment.
A week of recovery, but risks remain
The market ended the week in positive territory, supported mainly by technology stocks and expectations surrounding artificial intelligence. However, rising bond yields, geopolitical tensions, and uncertainty about inflation remain important factors.
The key question is whether the AI-driven momentum can sustain Wall Street as investors assess the impact of elevated interest rates on the economy and corporate valuations.
