US stock markets closed sharply lower on Wednesday after new inflation figures were released. Technology companies investing heavily in artificial intelligence were hit particularly hard, as higher interest rates make their financing more expensive.
The S&P 500 lost 1.1 per cent, closing at 7,718.94 points. The Nasdaq, which includes many technology companies, fell 1.9 per cent to 26,692.87 points. The Dow Jones was virtually unchanged, down 0.1 per cent. According to Associated Press, Wall Street therefore experienced its worst trading day since July.
The immediate trigger was the US inflation report for September. Consumer prices were 3.7 per cent higher than a year earlier, compared with 3.4 per cent in August. Prices rose by 0.6 per cent month on month. Core inflation, which excludes food and energy prices, also increased to 2.6 per cent year on year.
The figures strengthened expectations that the Federal Reserve will keep interest rates high for longer or raise them again. The central bank raised its policy rate in September for the first time in three years, according to AP. The next policy meeting is scheduled for 27 and 28 October. The final decision depends on new economic data and had not yet been taken on Wednesday.
The reaction was strongest among companies dependent on large amounts of borrowed money for data centres, chips and computing power. Oracle lost 8.8 per cent, while cloud provider CoreWeave fell 15.5 per cent. Nvidia lost 3.2 per cent, Broadcom 3.1 per cent and Advanced Micro Devices 5.7 per cent, AP reported. Reuters described the same movement as a response to higher financing costs for the AI sector.
The falls in share prices do not mean that demand for AI services has suddenly disappeared. They mainly show that investors are giving greater weight to higher interest rates when valuing companies that still have to invest heavily before their profits can catch up with expectations. When bond yields rise, future profits generally become less attractive and newly borrowed capital becomes more expensive.
Banks were also under pressure. Bank of America lost 4.8 per cent, according to AP, after reporting weaker quarterly results. It had also been announced on Tuesday that the US government had imposed a $1.2 billion fine for breaches of money-laundering and sanctions rules. For Dutch investors, the broader interest-rate trend is particularly relevant: through exchange rates, bond markets and technology shares, it may also affect European markets, although the sources do not yet identify any specific consequences for the Netherlands.
One story, several perspectives
What is established
- US inflation rose to 3.7 per cent year on year in September.
- US stock markets closed lower on Wednesday.
- AI-related shares were among the biggest fallers.
- The Federal Reserve has not yet decided on a further interest-rate rise.
Left
Arguments The emphasis is generally on the risk that high interest rates will slow investment, employment and technological development. Central banks must safeguard price stability without unnecessarily choking the economy; targeted support can protect vulnerable households.
Values Purchasing power, employment and long-term public investment.
Consequences A more cautious interest-rate path could support growth and investment, but increases the risk that inflation remains above target for longer.
Centre
Arguments The institutional approach is to make interest-rate decisions based on data. The Federal Reserve must anchor inflation expectations while also taking account of the effects on growth, lending and financial stability.
Values Monetary credibility, proportionality and economic stability.
Consequences A gradual course can give markets predictability, but requires patience when price rises prove persistent.
Right
Arguments The emphasis is generally on bringing inflation down quickly and avoiding cheap money that keeps inefficient companies or excessive debt afloat. Companies should be able to fund their AI investments themselves.
Values Price stability, financial discipline and market risks among private-sector parties.
Consequences Higher interest rates can reduce overvaluation and debt, but may also slow healthy investment and productivity growth.
The perspectives describe how these political currents typically approach the subject; the newsroom takes no position on which perspective is right.
