Markets Reverse; S&P 500 -0.41%, Nasdaq -0.72% as Brent Oil Surges Back to ~$107 on Iran Deal Uncertainty; FOMC Hawkish Minutes Weigh
US equity markets reversed Wednesday's gains on Thursday May 21, 2026, as Brent crude oil surged back above $100/bbl — erasing the prior session's ceasefire-driven relief rally — while investors digested the hawkish signals from the April 28–29 FOMC minutes released the previous day. **Market Performance (May 21 Close):** - **S&P 500**: approximately **−0.41%** to ~7,402 — now approximately −1.3% from the May 14 all-time high of 7,501.24 - **Nasdaq 100**: **−0.72%** — technology and growth stocks more vulnerable to the rate-hike risk from FOMC minutes - **Dow Jones**: approximately flat to slightly negative - **DXY Dollar Index**: ~99.1–99.3 — supported by the hawkish Fed signals ruling out near-term cuts **Oil Surge — Iran Deal Uncertainty Reversal:** The Iran ceasefire reports that briefly pushed Brent below $100/bbl on May 20 proved premature. No official ceasefire announcement materialized, and traders quickly reassessed: - **Brent crude**: surged back to approximately **$107/bbl** — near the post-Trump-Xi summit range - **WTI crude**: back above **$100/bbl** - The IEA had previously warned (May 15) that even if the Iran-Israel conflict ended immediately, the global oil market would remain 'severely undersupplied until at least October 2026' — capping any durable ceasefire-driven oil price decline **FOMC Minutes Compound the Pressure:** The previous session's release of FOMC April minutes (showing officials discussed rate hikes) continued to weigh on sentiment. The combination of: 1. **Rate hike risk** — explicit in April FOMC minutes 2. **30Y Treasury at 5.189%** — 18-year high, Citi targeting 5.5% 3. **Oil back at $107** — Iran war energy shock continuing 4. **Housing data** — single-family starts -9% shows rate transmission ...represents the classic stagflation trap playing out in real time: energy-driven inflation prevents the Fed from cutting (or forces hikes), while rising long-end yields tighten financial conditions independently of the policy rate. **Calendar Ahead:** - **May 22**: May flash PMIs (S&P Global) — first PMI read post-Trump-Xi summit; key signal for whether business conditions are improving or deteriorating - **June 16–17**: FOMC meeting — Warsh's first SEP + press conference; rate hold expected (~97%) but balance sheet trajectory is the critical variable - **July 23**: Section 122 tariff cliff — Congressional action required to extend tariff authority **Recession Probability Context:** Goldman Sachs 30%, JPMorgan 35%, Moody's Analytics 49% recession probability estimates were compiled before the FOMC minutes rate hike discussion became public. Updated forecasts are expected ahead of or following the June 16–17 FOMC.
