The AI Selloff Resumed | Banks Built for High Rates | Index Rules Moved Money | Big Bets Against a Hike

Oil jumped and tech fell on Friday, closing a week of hot inflation data.

The S&P 500 fell 1.1% to about 7,661, and the Nasdaq Composite lost 2.1%. The Dow slipped 0.3% after rising as much as 0.8% in the morning. The Russell 2000 fell 1.7%. The S&P 500 lost about 1.9% for the week. The 10-year Treasury yield edged down to 5.09%, gold rose about 0.4% to near $4,190, and bitcoin traded near $81,500.

U.S. crude settled 3.5% higher at $101.41, and Brent rose more than 3% to near $110. On Thursday, physical North Sea cargoes cost about $20 more than Brent futures. On Friday, futures swung about 4% in a few hours with no single trigger. Import prices rose 1.1% in September, and prices outside fuel were up 6.0% from a year earlier.

Oil climbed. Growth stocks did not.

The AI selloff resumed on Friday, and software fell with the borrowers.

CoreWeave fell about 12%, leaving the stock down about a quarter for the week. Insuring its debt against default cost a record this week, S&P Global data showed. The company issued no news on Friday.

Software and cybersecurity shares fell 5% to 10%, and no company in the group issued news to explain it. Palo Alto Networks (PANW) fell about 7.6%, and CrowdStrike (CRWD) lost about 7%. A Palo Alto security flaw cited as a cause was disclosed Wednesday, two days earlier. The VanEck Semiconductor ETF fell for a ninth straight session.

Leverage First, Then Growth

The selling began this week with the most indebted AI builders. On Friday it reached software companies that borrow far less, and no single cause explains the move. Broad junk-bond funds fell less than 0.5%, a sign the debt strain stayed inside AI. If high-yield funds start falling with CoreWeave's bonds, the stress is spreading.

Two regional banks took losses now to earn more later, and two planned for a December rate increase.

Truist Financial (TFC) sold $8.6 billion of mortgage bonds yielding 2.67% and bought $7.2 billion yielding about 5.6%. The pretax loss was about $1.4 billion. On a simple estimate, the higher yields would earn it back in a little more than eight years. Regions Financial (RF) repositioned about $850 million of bonds at a $15 million loss. Management expects to earn that back in about two years.

M&T Bank (MTB) built one Fed increase in December into its fourth-quarter income forecast, as did Regions. Its finance chief called the bank roughly neutral to short-term rates, so the forecast leans on assets repricing higher. M&T shares fell 1.6%.

Built for High Rates

Truist's new bonds mature sooner than the ones it sold. The trade pays off only if rates stay high long enough to earn back the loss. Two banks planned for one more increase in December, while Kalshi traders priced little chance of one in October. If yields fall before the new bonds mature, Truist's payback stretches.

Index rules moved money this week, weeks or months before any forced selling.

MSCI proposed moving Indonesia out of its emerging-markets index. It would skip frontier status for a standalone category. The Jakarta Composite fell 11.57%, its steepest drop since January 1998. The rupiah weakened past 18,000 per dollar. A decision is due by June 30, 2027.

Strategy fell about 9.6% in its first full session since MSCI's new index rules. Bitcoin slipped less than 1%. Reuters reported that Strategy is on MSCI's list of potential deletions, and the final list is due Nov. 11.

Membership Is Money

Index membership decides which passive funds must own a stock. Indonesia's decision is more than eight months away, yet Jakarta had its worst day in nearly three decades. Part of Strategy's drop came in a broad selloff in crypto and AI-linked shares. The index effect cannot be cleanly separated. Investors sold before any change took effect.

Hot reports and big trades barely moved the Fed bet.

Two Kalshi orders bought 50,000 "no" contracts each on an October hike, risking about $88,000 to win about $12,000. Buyers followed both trades, and the contract ended near 13 to 14 cents, about where it stood before the data. Futures put the odds of an October hike at about 15% on Friday, CME FedWatch data showed.

Two more Brazilian polls put the Oct. 25 runoff within one point. PoderData showed a 50-50 race, and CNT/MDA had Flávio Bolsonaro at 50.5%. Polymarket's contract on a Flávio win slipped to about 76 cents late Friday. Its biggest hourly drop came with no new poll.

Prices, Not Polls

The Fed contract shrugged off two hot reports and stayed close to futures. The Brazil contract still prices a clear favorite in a race the polls call a toss-up. Each price reflects what traders will pay under the contract's rules. Neither price is evidence of the outcome.

Courts, not the CFTC, set the pace this week.

Underdog sued Tennessee, its seventh state, over a preemption argument an appeals court rejected in September. That ruling binds the Nashville court, so the suit mainly preserves Underdog's right to appeal. Three petitions on the question sit at the Supreme Court. A federal judge also refused a joint request by the CFTC and Gemini to erase a $5 million settlement.

The Courts Keep the Clock

The CFTC proposed on Oct. 9 to define event contracts as swaps, a step toward federal oversight. Judges are moving on their own schedule. A Nashville court must follow an appeals ruling, and a Manhattan judge would not reopen a settled case. So far, the regulator's new direction has not undone those rulings.

The week ended with the AI trade's financing question still open.

CoreWeave lost about a quarter of its value, and software followed with no company news. Banks planned for high rates while Kalshi priced little chance of an October hike. U.S. crude settled above $100. Index rules moved money in Jakarta and in Strategy's stock.

Capital moves early. Coverage catches up. The gap between the two is worth watching.
