The Brief

The S&P 500 fell 0.61 percent on Friday to close at 6,632 — its lowest finish of 2026 and roughly 5.3 percent below its late-January record — capping the index’s first three-week losing streak in approximately a year. The decline extends a sell-off driven by the Strait of Hormuz closure, oil prices up 65 percent year-to-date, and a Q4 GDP revision to 0.7 percent that has put the word stagflation back into daily use.

The Report

The S&P 500 closed at 6,632.19 on Friday, shedding another 0.61 percent after Thursday’s sharper 1.5 percent drop to mark the worst finish for the index since it hit a record high of 7,002 on January 27. The Dow Jones Industrial Average fell 0.26 percent to 46,558 and the Nasdaq Composite lost 0.93 percent to 22,105. Six of the S&P 500’s eleven sectors ended the session in the red, led by technology at minus 1.29 percent, while utilities and consumer staples posted modest gains.

The three-week decline — the index’s first sustained losing streak since early 2025 — sits at the intersection of a geopolitical energy shock and an increasingly uncomfortable domestic economic picture. Iran’s IRGC declared the Strait of Hormuz closed on March 4, choking roughly one-fifth of the world’s daily oil supply. Brent crude has surged past $100 a barrel, with West Texas Intermediate settling at $98.71 on Friday. Oil is up 65 percent since January, including a 35 percent spike in the first twelve days of March alone. U.S. fuel prices have risen nearly 35 percent from their January lows.

The macro data has compounded the pressure. Fourth-quarter 2025 GDP was revised down to 0.7 percent annualised growth — half the advance estimate of 1.4 percent — with a 43-day federal government shutdown in late 2025 cited as the primary drag. February’s payroll report showed a loss of 92,000 jobs, the first contraction since 2020, and the unemployment rate ticked up to 4.4 percent. Core PCE inflation held at 2.8 percent, still well above the Federal Reserve’s 2 percent target. Consumer sentiment fell to 55.5 in March, its lowest reading of the year, with interviews conducted after the Iran escalation dragging down results that had initially shown improvement.

The Federal Reserve, which meets March 17–18, is widely expected to hold rates at 3.50–3.75 percent. Markets that began the year pricing four rate cuts now expect one or two at most. Former White House energy adviser Bob McNally described the Hormuz situation as one the market had considered “absurd” even as a possibility, adding that the world cannot grow without 20 percent of its energy in the short term. The International Energy Agency has coordinated the release of 400 million barrels from strategic reserves across 32 economies — the largest emergency deployment in history — though analysts have described the measure as insufficient to offset the scale of the disruption.

Defence contractors Lockheed Martin, RTX, and Northrop Grumman reached new 52-week highs during the week. ExxonMobil is up 25 percent year-to-date. On the other side, Microsoft has fallen nearly 20 percent from its highs, Apple lost more than $250 billion in market capitalisation in the week, and airlines declined more than 8 percent. The VIX closed Thursday at 27.29 — its highest reading since 2022 — before easing slightly on Friday. The S&P 500’s next major technical support sits at 6,500, its 200-day moving average. Not one of the 21 Wall Street strategists surveyed by Bloomberg at the start of the year predicted a decline, with year-end targets ranging from 7,100 to 8,100.

The Angle

The soft landing was always a narrative about what wouldn’t happen — inflation wouldn’t stay sticky, oil wouldn’t spike, jobs wouldn’t contract, all at the same time. The market is now adjusting to the discovery that these things were not excluded by policy. They were excluded by the absence of a sufficient shock. The shock arrived on March 4, and what it revealed was not a new vulnerability but an old one: the entire architecture of post-industrial economic stability rests on energy geography that no central bank controls and no diversification strategy has yet replaced.

The Fed’s paralysis is worth examining precisely because it is not incompetence. It is the correct output of an institution designed to choose between inflation and unemployment being handed a situation in which both are deteriorating simultaneously, driven by a variable — Middle Eastern oil transit — that monetary policy cannot reach. The tool was not built for this. The debate about whether rates should be higher or lower is the wrong debate. The right debate is about a global economy that still routes a fifth of its energy through a single maritime corridor and has no short-term alternative when that corridor closes.

Twenty-one strategists, zero predictions of decline, and an index now trading 7 to 18 percent below every one of their year-end targets. The gap between forecast and outcome is not a failure of analysis. It is a measure of how much of the current economic model depends on conditions it does not control and cannot reproduce once they are interrupted.
