Coverage: October 10–16, 2026
The AI trade discovered a rather inconvenient feature of capitalism this week: borrowed money charges interest. Wednesday's inflation surprise sent the Nasdaq down 1.88%, while Oracle plunged 8.8% and CoreWeave shed 15%. The Philadelphia Semiconductor Index extended its losing streak to seven sessions by Thursday as investors reconsidered the financing behind Silicon Valley's increasingly expensive ambitions.
Thursday brought a partial recovery. The S&P 500 gained 0.33% to 7,744.06, the Dow rose 1.08% to 52,177.69, and the Nasdaq managed a 0.08% gain. Healthcare led the rebound, with Eli Lilly climbing more than 3% and UnitedHealth adding 2.8%. Investors were rotating toward defensive businesses while technology companies worked through their borrowing-cost headaches.
There was one rather awkward contradiction: Taiwan Semiconductor reported a 68.7% increase in quarterly profit. AI demand remains substantial. Investors are simply becoming more particular about who pays for it.
September's Consumer Price Index climbed 0.6%, lifting annual inflation to 3.7% from August's 3.4%. Gasoline prices jumped 9.1% during the month, accounting for more than half the increase. Core inflation rose a comparatively modest 0.3%, although its annual rate also accelerated to 2.6%.
Wholesale prices delivered an encore Thursday. The Producer Price Index surged 1.3%, its largest monthly increase since March 2022, pushing annual producer inflation to 6.3%. Energy contributed heavily, but prices excluding food, energy, and trade services also advanced 0.5%.
The distinction matters. Energy shocks can fade as supply conditions improve. Broader price increases create a more complicated assignment for the Federal Reserve, particularly when consumer spending continues to hold up.
American shoppers seem determined to keep the cash registers ringing. September retail sales increased 0.8% to $745 billion, exceeding economists' expectations. August's growth was revised higher to 1.3%.
There is a catch: retail sales measure dollars spent rather than inflation-adjusted purchasing power. Expensive gasoline can make spending figures look stronger even when households purchase roughly the same amount of stuff.
The banking sector offered another sign of economic resilience. JPMorgan, Citigroup, and Wells Fargo reported higher net interest income, supported by continued lending. Citigroup's average loans increased 12% from a year earlier, while Wells Fargo's rose 11%.
Deposit competition is becoming more expensive, however, and Citi and Wells Fargo increased their provisions for potential credit losses. The borrowers are still borrowing. The lenders are keeping a closer eye on the bill.
Federal Reserve Chair Kevin Warsh spent the week defending his vision of a quieter central bank, a difficult ambition when nearly everyone else on the committee appears to enjoy having a microphone.
The September inflation report briefly drove October rate-hike expectations sharply higher. By Friday morning, markets were again favoring December for the next increase. Speaking at the IMF meetings in Bangkok, Warsh praised the economy's resilience while declining to preview the October 27–28 policy decision.
Meanwhile, the 10-year Treasury yield retreated roughly 10 basis points Thursday to 5.086%, offering equities some relief after weeks of rising borrowing costs. Warsh may prefer fewer hints about monetary policy, but investors will continue dissecting every syllable.
The Middle East supplied another expensive reminder that geopolitical risk eventually finds its way into everyday prices.
Brent crude crossed $106 per barrel Wednesday amid escalating attacks on Saudi infrastructure and shipping near the Strait of Hormuz. Energy traders also had to weigh renewed uncertainty surrounding Russian supplies and the fragile arrangements involving Ukraine.
On Thursday, the International Energy Agency agreed to accelerate the release of more than 20 million barrels of diesel, alongside remaining supplies from its previously announced emergency reserves program.
The release offers an additional source of near-term supply, although accelerating previously committed barrels is different from expanding the overall reserve program. For markets, the immediate issue remains the same: sustained energy disruptions complicate inflation, monetary policy, and corporate profit margins.
The Los Angeles Dodgers assembled another star-studded roster with their sights set on a third consecutive World Series title. Milwaukee apparently missed the casting announcement.
The Brewers completed a four-game NLCS sweep Thursday, overcoming an early 4–0 deficit to win Game 4 by a 6–4 score. Garrett Mitchell delivered the go-ahead home run, Jake Bauers earned series MVP honors, and Milwaukee secured its first World Series appearance since 1982.
The Brewers now await either Cleveland or Tampa Bay, with the Guardians holding a 2–1 ALCS lead entering Friday.
