S&P 500 futures are down 0.8% at 6,587 after Iran formally rejected the U.S. 15-point ceasefire proposal transmitted via Pakistan, reversing all but a fraction of yesterday's relief rally.^[1] Tehran's foreign minister called Washington's approach an "acknowledgment of failure" and countered with a five-point framework demanding Iranian oversight of Strait of Hormuz transits — a non-starter for U.S. negotiators. The Nasdaq 100 is leading the selloff at –0.85%, consistent with its yield sensitivity. WTI crude has bounced more than $4 from yesterday's ceasefire-driven low, back above $91.

What's driving it

Iran's rejection is the overnight story. Foreign Minister Abbas Araghchi issued the formal rejection and framed the U.S. proposal not as a peace overture but as a concession of strategic weakness.^[1] Iran's own five-point counter demands Hormuz influence the U.S. has no room to grant. Overnight, the UAE, Kuwait, and Bahrain all activated air defenses against Iranian drone and missile incursions — military operations are running in parallel with whatever back-channel activity Washington claims is happening. Trump, speaking late Wednesday, said Iran wants a deal "so badly" but is "afraid to say it." That read is not what Iranian state behavior is communicating.

The oil move is the mechanical expression of the rejection. WTI climbed back to $91.64, battling resistance at $92, before a reported U.S. crude inventory build of 13.4 million barrels — the largest weekly draw in since November 2023 — capped the overnight spike.^[2][4] Roughly 20% of global oil and LNG transits the Strait; the market had briefly priced a resolution path after yesterday's proposal confirmation, and that optionality is now off the table.^[3] The 10-year ticked up 2 basis points to 4.35%, gold slipped on the stronger dollar, and the Russell 2000 — which outperformed sharply yesterday on rate-cut re-pricing — is giving back the most on a relative basis.

On the calendar

Initial Jobless Claims for the week ending March 21 hit at 8:30 a.m. ET; consensus is 207K against a prior 205K. A meaningful surprise matters in either direction: the last CPI print came in at 3.5%, and the market has fully priced out 2026 Fed cuts, so any labor softness that re-opens the easing conversation will be amplified. Durable Goods Orders, originally scheduled for today, have been rescheduled to April 7. Fed speakers are heavy: Cook, Jefferson, Logan, and Barr are all on the calendar — any dovish lean from that roster will get exaggerated attention given current pricing.

Movers

Super Micro Computer (SMCI) is up 8.2% pre-market at $24.05, mechanical short covering after its 26% collapse on March 20, when prosecutors charged several employees with smuggling Nvidia chips to China.^[5][6] No new catalyst today; the stock remains more than 60% off its recent highs and the legal overhang is unchanged.

Alphabet is down roughly 1.5% alongside broad tech pressure — yield backup and risk-off tone from the Iran headlines, nothing company-specific.

Earnings on deck

Carnival Corporation (CCL) reports Q1 fiscal 2026 before the bell. Consensus calls for revenue of $6.14B and EPS of $0.18.^[7] The stock is down 16.6% year-to-date. The number that matters is forward guidance: fuel costs swing ~$145M annually per 10% crude move, and management is now pricing itineraries into an environment where WTI just reversed a 9% decline in 24 hours. Booking pace and pricing power commentary will be the read-through for the consumer discretionary sector.

The setup

Yesterday's relief trade is unwound. The session's live variable is how much war premium the market reassembles — oil at $95 or above reconstitutes the stagflation thesis and pressure on the long end; oil holding near $90 signals the market treats Iran's rejection as negotiating posture rather than genuine escalation. Jobless claims at 8:30 and the Carnival print will frame the domestic side, but geopolitical headlines will override. Trump's self-imposed strike deadline was paused Monday for five days. Today is day three.
