Causa, Edition 002. Friday 23 October 2026. Intraday, 15:30 New York. Talk of new strikes on Iran pushed Brent to a six-month high and pulled the Dow lower. Gold fell below $4,000, which puts Thursday's gold explanation on the edge of failing its own test. ## Update, Saturday 24 October 2026, after Friday's close At the close, spot gold was at $3,994.90 and the 10-year yield at 4.988%, both under the lines set on Thursday, so F-004 was marked triggered on the Scorecard. Gold futures closed just above $4,000, at $4,007.90. We rule on the spot price the call was written against, and the original file stays online unchanged.

The Dow closed down 1.2% at 52,215.16, a little deeper than the 1.1% fall we reported at 15:30. The S&P 500 fell 0.5% to 7,623.68 and the Nasdaq 0.2% to 25,955.34.

We used a market quote of 4.988% for the 10-year yield. Our method rules on the US Treasury’s daily yield, which was 5.00% on 23 October, and 5.00% is not below the line. F-004 is open again until 6 November, and the change is logged on our corrections page.

Airlines fell more than 4%, and the Dow was down about 1.1% by mid-afternoon.

The Nasdaq closed down 2.6%, its worst day since June, and the 10-year Treasury yield fell to 4.955%, below 5% for the first time in a month. The larger fall in yields supports our Thursday reading of haven demand for Treasuries.

On Thursday we wrote that our gold explanation fails if gold closes below $4,000 on a day the 10-year closes below 5%. Both conditions held this afternoon. If they hold at the close, the Scorecard marks the call triggered, and the original file stays online unchanged.

Evidence grade A. Brent rose for a third straight week on reports that the US and Israel are weighing new strikes on Iran after the US midterms. No supply has been lost; the move is a premium for the risk of a wider war. Wrong if: Our read is that oil now prices a wider war, not a passing scare. If Brent closes below $108, where it traded before Wednesday's Shaybah strike, on any session by 6 November, the market has judged the escalation risk overdone and this file overstated it. (F-006, deadline 6 November 2026) ### [Gold breaks $4,000, and our explanation is failing its test](https://causamarkets.com/cause/gold-breaks-4000/) Gold −0.7% to $3,996. Evidence grade C. Gold fell below $4,000 on a day Treasury yields stayed below 5%, the condition we set for Thursday’s rate explanation to fail. Our best explanation now is forced selling by investors covering losses elsewhere. The grade stays C. Wrong if: If forced selling is the cause, gold should stop falling once stocks calm down. If gold closes below $3,900 on a day the Nasdaq closes above 26,000, by 13 November, the selling is not coming from the stock rout and this file is wrong. (F-007, deadline 13 November 2026) ### [Oil pulls the Dow down while chips steady](https://causamarkets.com/cause/oil-pulls-the-dow-down/) US stocks Dow −1.1% to 52,269. Evidence grade B. Selling rotated from chips to the broader market. Airlines fell on fuel costs, American Express on job cuts and a revenue miss, and Verizon on reports about SpaceX. Chips stabilised after Thursday’s worst Nasdaq session since June. Wrong if: Our read is that rising oil is now the main weight on stocks, alongside AI doubts. If the S&P 500 closes above 7,757.17, its level before Meta reported, on any session by 6 November while Brent is still above $112, oil is not holding stocks back and this file is wrong. (F-008, deadline 6 November 2026) ## What we are watching - 27 and 28 October, Federal Reserve meeting: Bets on a hike next week have faded to about 5%, with December still the live meeting. Oil at $116 is the reason that could change. - 28 and 29 October, Microsoft, Alphabet and Amazon report, plus GDP and PCE inflation: The AI spending question comes back in full, on the same days as the inflation figure the Fed watches most closely. - 3 November onward, US midterms and the reported strike plans: Oil is pricing strikes reported for after the vote. Either the plans move ahead or the premium starts to leak out.
