SPY’s 1.08% decline reflected hotter U.S. inflation and a global retreat from high-growth technology shares, while investors sought shelter in Treasuries and gold.
SPY fell 1.08% on the session, matching the S&P 500’s reported decline, as hotter U.S. inflation and a retreat from high-growth technology shares weighed on stocks. The cross-asset picture was defensive: equities slid, Treasury yields declined, gold rose and Brent crude eased. The available reports did not establish a verified move in major currency pairs, leaving the dollar’s direction unclear.
The S&P 500 lost 1.08% to 7,721.49 in the reported U.S. close. The Nasdaq Composite fell 1.85% to 26,701.48, while the Dow Jones Industrial Average slipped 0.09% to 51,624.87. The larger Nasdaq decline reflects pressure on growth-oriented technology shares, which also weigh on SPY.
The selloff reached markets overseas. Bloomberg reported the MSCI Asia Pacific Index fell 2.9% and emerging-market shares dropped 3.1% on October 15. South Korea’s Kospi tumbled 7.6%; Samsung Electronics and SK Hynix each lost more than 9%. Earlier that day, Reuters reported S&P 500 E-minis down 0.27%, Nasdaq 100 E-minis down 1.1% and Dow E-minis up 0.32% at 5:50 a.m. ET. The Nasdaq had fallen more than 3% from its record high the previous week.
Inflation drove renewed concern about Federal Reserve policy. September’s consumer price index rose 0.6% from August and 3.7% year over year, above economists’ 3.6% estimate. Core inflation, excluding food and energy, rose 2.6% year over year, also ahead of forecasts. Persistent price increases can keep borrowing costs high and reduce the present value investors assign to future earnings, putting particular pressure on technology companies valued for growth.
Rate expectations shifted, though estimates varied across reports and through the session. Reuters cited CME FedWatch data showing a 27% chance of a rate hike later in October, up from 20% a week earlier, and a 67% chance of a quarter-point hike in December. Another report described a stronger immediate repricing after the CPI release. These are market-implied probabilities, not a Federal Reserve decision. Fed Vice Chair for Supervision Michelle Bowman said she saw no urgency for further action and that policymakers needed time to assess developments.
Treasuries moved higher in price as investors sought safety: the 10-year yield fell 11 basis points to 5.08%, its lowest in three weeks. BlackRock’s Vasiliki Pachatouridi said yields were “the highest we have seen in multiple decades,” offering income and an alternative to equities. The decline in yields suggests defensive repositioning even as inflation raised the possibility of tighter policy.
Gold rose 1.2% to $4,154.30 an ounce, while Brent crude fell 1.9% to $104.03 a barrel, Bloomberg reported. Oil remained expensive despite the pullback. For households, energy costs can feed into transportation and other prices; higher interest rates can also raise costs for mortgages, credit cards and business financing. The market moves do not determine what consumers will pay next, but they underscore why inflation remains central to rate expectations.
Investors also questioned whether the AI boom can generate returns commensurate with its large computing costs. Anthropic’s third-quarter revenue reportedly reached $16.8 billion, up 45% from $11.5 billion in the second quarter. It was also reported to be cash-flow positive, with an 11% adjusted operating margin. The figures show substantial revenue, but markets are scrutinizing growth and the cost of producing it. Investors were awaiting U.S. producer prices, retail sales, jobless claims and business surveys for more clues on inflation, economic momentum and the Fed’s next move.
