Stocks Fell After Hitting Records. High Borrowing Costs and $100 Oil Are Why

Stocks fell on Oct. 7, just a day after closing at record highs. Asian shares fell 1.2% as well. Bloomberg The rate on the 10-year U.S. government IOU, which helps set mortgage and loan rates, was 5.31% on Oct. 8, up 0.02 percentage point from the day before.

Bonds had swung the week before. The bond market turned around on Thursday, Oct. 1, according to live coverage of that day. The Wall Street Journal That morning the 10-year rate hit near 5.34%, a 24-year high, before turning lower. Two sessions earlier, on Sept. 29, the headline was '10-Year Treasury Yield Pushes Higher Despite Oil-Price Decline.' The Wall Street Journal In that session the 30-year rate hit its highest since 2002.

Oil stayed above $100. Brent oil, the world benchmark, was $103.86 a barrel by 9:20 a.m. Eastern Time on Oct. 1. Fortune The U.S. Energy Information Administration forecast Brent will average $105 a barrel in the fourth quarter of 2026, $14 a barrel higher than in last month's forecast. U.S. Energy Information Administration In another session Brent settled at $104.61 a barrel, down $3.02, or 2.81%. Reuters In earlier sessions New York oil fell 2.4% to $100.05.

In a separate session the 30-year rate fell 0.050 percentage point to 5.296% while the S&P 500 and Nasdaq rose and oil steadied. The Wall Street Journal Further back, in an August session, Brent rose 2.4% to $93.78 while stocks fell as bond rates and oil rose together. The Wall Street Journal Before the Oct. 7 drop, the S&P 500 rose 0.66% to 7,773.95 points and the Nasdaq rose 1.05% to 27,477.31 points. Reuters

The broader context here is pressure from two sides at once. Rates above 5.3% make borrowing dearer for families and firms and make future company profits worth less today. Oil over $100 adds costs and pushes up headline inflation, the general rise in prices.

In my view, the order of events mattered. Stocks bounced when oil fell in mid-September. Stocks lost that help when rates hit multi-decade highs in late September and early October. The Oct. 1 peak near 5.34% and quick turn, then records, then another fall, points to thin trading in long-term bonds. Stocks and bonds are not balancing each other well when supply and energy shocks rule.
