Dow jumps 1%, oil sinks 5% on Iran-talk hopes; AI earnings lift futures
Wednesday, October 21, 2026 · as of Oct 21, 6:26 AM ET · covers the prior trading session
Small caps and the Dow led Tuesday as WTI fell 5% on reports of US–Iran diplomacy, while a weak housing-starts print and a 3bp drop in the 10-year yield followed. Overnight, strong Super Micro and SpaceX results lifted Asian tech and Nasdaq futures, though oil is climbing back toward $100.

Market snapshot
Why it mattered
Reported: Oil gave back ground on diplomacy headlines but has gained more than 10% this month on Middle East and Ukraine-related supply risk, per Trading Economics. Gold has fallen four straight sessions as oil-driven inflation worries raise rate-hike odds; markets expect the Fed to hold next week, with a December hike seen as possible. UK September CPI printed 3.5% vs 3.4% expected this morning. KOSPI rebounded 3.3% on chip strength and record early-October exports.
Our read (commentary, not investment advice): Tuesday looked like relief rotation — cheaper oil and lower long yields helped cyclicals and small caps more than megacap tech. The weak housing data and soft 10-year support that, but oil climbing back toward $100 can undo it quickly. Tonight's Meta, Tesla, IBM and Lam results are the next test for the AI trade that lifted futures.

Business lens
- Dairy (USDA weekly, week ending Oct 10, published Oct 15): 40-lb block cheddar $1.5793/lb (+12.1¢ w/w); butter $1.4907/lb (+12.1¢); nonfat dry milk $1.7534/lb (-18.4¢); dry whey $0.6621/lb (-1.9¢); barrel cheese unavailable. FMMO September all-market average: Class III $16.04/cwt, Class IV $18.94/cwt. Class III futures benchmark ~$15.37/cwt on Oct 20 (+0.2%), cheese benchmark ~$1.69/lb Oct 21 (-0.8%), per Trading Economics CFD quotes. CME spot butter/NDM/whey: unavailable. Week direction: cheese and butter both higher in the latest USDA week.
- Feed: corn ~$4.60/bu (sixth straight loss), soybeans below $12.50 (eight-week low), wheat ~$6.40 (fifth straight loss), per Trading Economics; soymeal unavailable.
- Fuel: U.S. on-highway diesel $6.276/gal, week of Oct 19, up 9.7¢ w/w (EIA).
- Freight: unavailable.
- Rates: SOFR 3.87% (Oct 19); hike risk keeps floating-rate borrowing costs elevated.
Our read (commentary): Butter's bounce helps, but at ~$1.49 it is still very low and NDM just dropped 18¢, so Class IV pressure persists. Class III futures near $15.37 sit below September's $16.04, so milk checks are not improving yet. Cheaper corn and soybeans ease the feed side of the margin, but $6.28 diesel offsets part of that on hauling and field costs.
