Why markets moved overnight

Sunday, October 18, 2026 · Updated Oct 18, 2026 07:14

With no trading over the weekend, Friday's split close still stands, semiconductors and Broadcom leading lower while Brent held at 109.86 dollars, and Iran's conditional offer to reopen Hormuz is the new fact markets will price on Monday.

Why it matters: The weekend changed the oil story, not the price: a dated Iranian reopening sequence now sits against a crude price built on Hormuz closure, while the AI complex goes into the week 11.8 percent lighter and Treasury yields hold a 12 to 16 basis point weekly rally.

Data as of Market close Friday, October 16, 2026

Broadcom fell 4.52 percent on Friday, the largest move in the tables, and the semiconductor index fell 4.14 percent, taking its weekly loss to 11.8 percent. No company specific announcement in this morning’s reporting explains the sector fall: today’s technology brief recaps the close and points back to Friday’s chip selloff coverage on this site, which read the move as a repricing of the AI complex rather than a demand break.

Meta fell 3.72 percent on Friday and the broader technology sector fell 3.02 percent, down 7.7 percent on the week, with the Nasdaq 100 down 2.5 percent on the day. Today’s technology reporting offers no single driver for Meta: the Meta development in this morning’s edition is the company’s removal of training language from its business terms, a regulatory story that the reporting does not present as the cause of the share move.

Brent crude rose 3.72 percent on Friday to settle at 109.86 dollars a barrel, up 4.91 percent on the week, on the Hormuz supply risk premium that built through the week, as covered in Friday’s Brent story on this site. The price has not traded since. What changed over the weekend is the story around it: see today’s Iran Hormuz reopening offer story, in which Tehran puts a six day reopening sequence on the table if Washington accepts its conditions.

Natural gas fell 3.71 percent on Friday to 3.12 dollars per million Btu. The fall came in Friday trading after the weekly storage report: the build came in below the five year average, but mild weather forecasts outweighed the tighter stock position, as covered in the gas storage story published here yesterday and referenced in this morning’s commodities edition.

Rare earth miners fell 2.71 percent on Friday, the worst weekly performer in the mining tables at down 11.05 percent, with uranium miners down 8.92 percent on the week and the lithium and battery basket down 8.15 percent. This morning’s mining brief references the miner equities slide covered here yesterday: the growth metals complex unwound through the week while gold itself held, closing Friday at 4,181.10 dollars, up 0.26 percent on the day.

The cross market read is a split tape carried into Monday. Energy was bid on physical supply risk and now faces a conditional de-escalation offer. Growth and AI exposed equities were sold for a second week on financing and valuation, not on reported demand. Treasury yields were nearly flat on Friday, the 10 year at 5.10 percent, up 0.9 basis points, after falling 14.6 basis points on the week, and the dollar index eased 0.16 percent to 101.84. Nothing in this morning’s reporting reprices that mix before Monday’s open except Hormuz.
