Three Weeks Down. No Floor in Sight.

Three losing weeks in a row. The S&P 500 set a new 2026 low on Friday, and the Nasdaq slipped below its 200-day moving average — a line that, once broken cleanly, tends to invite more sellers. The Dow dropped about 2% for the week. None of this is catastrophic yet, but the math is adding up in the wrong direction.

What made this week's selloff particularly nasty was the oil-equity feedback loop. Every time Brent crude ticked higher, equities cracked. Every risk-on attempt failed at the open or died by lunch. By Friday, WTI settled at $98.71 and Brent closed above $103 — the first time it has crossed $100 since August 2022. The week ended with crude up 5.5%. That kind of weekly move in energy is not a rounding error. It is a policy problem, a margin problem, and a Fed problem, all at once.

The only sectors that held up were the ones you hold when you are scared: Energy and Utilities were the week's sole winners. Everything else — tech, industrials, consumer discretionary, materials — leaked lower. Home builders dropped more than 5% as mortgage rates followed Treasury yields north. Travel names got hit hard as jet fuel costs started showing up in forward estimates. It was a defensive rotation with nowhere elegant to hide.

The new Supreme Leader of Iran, Mojtaba Khamenei, made the regime's position crystal clear on Thursday: the Strait of Hormuz should stay closed as a "tool to pressure the enemy." That single quote sent oil up another 3% and equities sliding into the weekend. When a geopolitical adversary telegraphs their leverage and means it, the market has no choice but to price accordingly.

Traffic through the strait has essentially stopped for commercial operators. Major carriers — Maersk, CMA CGM, Hapag-Lloyd — suspended transits weeks ago. The IRGC has already attacked more than 16 vessels. War-risk insurance premiums have exploded in some cases by 1,000%. Without insurance, commercial ships simply cannot sail. This is not a temporary blip. This is structured disruption.

Semiconductors were the outlier. The PHLX Semiconductor Index actually gained 1.8% for the week — an anomaly worth noting when everything else was bleeding. Nvidia held, Micron held, AMD held. The AI buildout trade has a certain structural stickiness: enterprises don't cancel multi-year infrastructure contracts because oil spikes for a few weeks. That resilience matters.

Software stocks told the opposite story — down more than 4% for the week. When energy prices threaten margins and the Fed can't cut, software multiples compress. Add in reports that Meta's next major AI model may face delays, and the communication services sector had a rough go of it. Goldman Sachs broke down from its up-trending channel and showed an RSI reading under 29 by Thursday. That is oversold, but oversold can stay oversold for longer than most people expect when macro headwinds are this heavy.

Retail investors were not passive observers. Vanda Research flagged record retail buying of oil ETFs on Thursday — $211 million flowing into pure-play energy products in a single session, beating records set in May 2020. The United States Oil Fund saw its third-biggest day of retail inflows ever. Individual investors are not hedging here. They are speculating on a continued oil run. Whether that is genius or hubris depends entirely on how the next few weeks play out at the strait.

The University of Michigan consumer sentiment survey came in at 55.5, down 1.9% from February. The more revealing detail: interviews completed before the Iran military action showed improvement from the prior month. The nine days of post-war data wiped out those gains completely. Americans felt better, then the bombs dropped, and they stopped feeling better. The survey director noted that the expectations index fell 4.4%, while one-year inflation expectations held at 3.4%.

That matters for the Fed. February CPI — collected before the oil shock hit — printed at 2.4% year-over-year. Clean. But that is ancient history. Economists are already modeling headline CPI reaching 2.6% to 2.9% in March, and potentially 3.5% by year-end if the strait stays closed. The market has already repriced Fed easing: expectations have gone from three cuts at the start of 2026 to fewer than one now. Jerome Powell walks into his March 17–18 meeting with his term expiring in May, oil above $100, a labor market that shed 92,000 jobs in February, and no clean policy answer. The Fed is boxed.

The rate decision is almost certainly a hold — CME FedWatch has it above 92%. But the dot plot and Powell's language on the oil shock will generate more market movement than the decision itself. If the dot plot shifts to signal two cuts in 2026 rather than one, you could see a sharp relief rally. If the language is hawkish and the dots remain tight, the pressure on equities continues.

The market is not trading on earnings or fundamentals right now. It is trading on a 21-mile-wide channel of water and what the Iranian regime decides to do with it. That is an uncomfortable place to be heading into a weekend — and into a week that will test every thesis you've built for 2026.
