Stock Daily — March 27, 2026

S&P 500 fell 1.67% to 6368.85, Nasdaq dropped 2.15% to 20948.36, Dow lost 793 points to 45166.64. This is the S&P’s fifth consecutive weekly decline — the last time that happened was May 2022. VIX surged to 31.05, up 13.16% on the day.

Today had one narrative: oil. WTI settled at $99.64/barrel, up 5.46%; Brent briefly topped $110 intraday. Trump had just announced on Truth Social the previous day that the deadline for strikes on Iranian energy facilities was being extended 10 days to April 6, saying “negotiations are going very well.” Then overnight, U.S.-Israeli forces struck Iranian steel plants and nuclear facilities. Reports emerged of 10,000 additional U.S. ground troops being deployed. Iran’s IRGC declared restrictions on the Strait of Hormuz, downed an MQ-9 drone, and activated Tehran’s air defense systems. Polymarket has ceasefire by March 31 priced at 1%, U.S. forces entering Iran by April 30 at 68%.

$100 oil is a psychological barrier and a substantive one. The University of Michigan consumer sentiment final reading came in at 53.3; one-year inflation expectations jumped to 3.8%, up 0.4 percentage points from last month’s 3.4% — the largest single-month increase since April 2025. Most eyes are on oil itself, but the inflation expectations jump is the stronger signal: a prolonged war is reshaping how ordinary people think about prices. That’s more dangerous than any single oil price level.

Fed Vice Chair Jefferson commented that the Iran war will push near-term inflation expectations higher, implying rates need to hold steady. Per Reuters, money markets have flipped from pricing two rate cuts for the year back in late February to now pricing roughly 60% probability of a rate hike within the year. Two months ago the conversation was about soft landings; now stagflation is being invited to the table. The 10-year yield at 4.44%, up about 2bp on the day — the absolute level isn’t extreme, but the direction is heading somewhere ugly. Fed Chair nominee Warsh’s Senate confirmation hearing could come as early as the week of April 13; his stance on wartime monetary policy will become a new pricing anchor.

Sector moves tell the whole story. Energy XLE +1.69%, Consumer Staples XLP +0.79%, Utilities XLU +0.57%. On the other side: Consumer Discretionary XLY led losses at -2.89%, Financials XLF -2.53%, Tech XLK -1.95%. The rotation from growth/cyclicals into defensives has been going on for more than a day or two. S&P hasn’t closed above the 10-day moving average since March 5 — every approach gets swatted down.

Iran’s foreign ministry spokesperson Baghaei was still saying on the 29th that U.S. proposals are “extremely extreme and unreasonable,” while Iran’s military claims U.S. forces have been pushed back from border areas. The diplomatic track and military track are completely disconnected. The Revolutionary Guards control nearly half of Iran’s economy — regime collapse means they get liquidated, so they have no exit. The market’s fear isn’t about war starting — it’s about not knowing how long or how big it gets. Schwab’s strategist put it bluntly: “Carrying any position over the weekend means accepting massive Monday risk.” Friday’s end-of-day sell-off accelerated as big money fled before the weekend — S&P closed at the session low.

Next week brings April 3 nonfarm payrolls, with the market expecting 48-55K new jobs and unemployment at 4.4%-4.5%. If payrolls come in weak while oil stays above $100, the stagflation trade intensifies further. If the Iran situation substantively de-escalates over the weekend — not just Trump’s verbal reassurances — an oversold S&P bounce to the 6500-6570 range wouldn’t be surprising. But as long as shipping risk in the Strait of Hormuz remains unresolved, any bounce is just a bounce.
