S&P 500 Hits New Record as Oil Drops After Iran Says Hormuz Is Open
The S&P 500 hit a fresh record as oil prices plunged after Iran said the Strait of Hormuz was open.
Mid-April markets rallied on that news, with the S&P up about 0.8% and the Dow rising roughly 678 points, or 1.4%. U.S. crude slid about 10.8% to $81.28 a barrel intraday and Brent fell about 10.3% to $89.13 after Iran's announcement. The move capped a two-week rebound that followed a nearly 10% correction in late March, as investors priced in a lower risk to Gulf oil flows.
Regional officials told the Associated Press the U.S. and Iran reached an "in principle agreement" to extend a ceasefire and allow further diplomacy. Earnings helped the rally, with Bank of America reporting $8.6 billion in first-quarter profit and Morgan Stanley jumping about 4.5% on better results. The 10-year Treasury yield eased from about 4.32% to 4.24% as lower oil stoked hopes for cooler inflation. Social posts reflected mixed takes: market strategists called the record unsurprising, while others warned a failed truce could trigger a historic crash, and one analyst estimated roughly a 55% chance the ceasefire holds versus 45% risk of a renewed flare-up.
Coverage shifted from upbeat market relief to caution about long-term inflation as new reporting stressed that lower oil may not erase price increases already baked into the economy. MS NOW highlighted economists such as Mark Zandi who say many prices are "sticky" and that cheaper gas will not quickly reverse higher fares, delivery costs, or construction expenses. That framing complicates the earlier narrative that the Strait reopening alone would deliver a clean disinflation and a sustained market rally.
📌 Key Facts
- The S&P 500 hit a fresh all‑time high, rising about 0.8% and extending a multi‑week rally that followed a nearly 10% correction in late March and a rebound of more than 10% over roughly two weeks.
- The rally is largely driven by investor optimism that the Iran war may de‑escalate — reports of an “in principle” agreement to extend a ceasefire and public comments (including from President Trump) suggesting the war could end soon helped reduce worst‑case growth and energy‑risk fears.
- Oil plunged after Iran and regional officials said the Strait of Hormuz was “fully/completely open” during a 10‑day ceasefire: U.S. crude fell about 10.8% to $81.28 and Brent dropped about 10.3% to $89.13 intraday; earlier Brent had settled near $94.93 (down from a roughly $119 peak but above pre‑war levels).
- Markets proved highly sensitive to official statements about Hormuz — the reopening announcement triggered the latest leg down in oil and lifted equities, with European markets jumping (CAC +2%, DAX +2.2%) while some Asian markets that had closed earlier were weaker.
- U.S. indexes logged broad gains (S&P +~0.8%, Dow +~1.4%/about 678 points, Nasdaq +~1%), extending a three‑week winning streak, while the 10‑year Treasury yield fell (from ~4.32% to ~4.24%) as lower oil eased near‑term inflation concerns.
- Corporate earnings and sector news supported the rally: Bank of America reported $8.6 billion in Q1 profit, Morgan Stanley jumped ~4.5% on results, and other financials rose (e.g., State Street, Fifth Third), while stocks like Netflix plunged (~11.5%) despite profits because of weak guidance and board changes.
- Economists caution that many price increases are 'sticky' — Mark Zandi and others say a drop in oil may not reverse higher costs already passed through to consumers, including higher airfares, ride‑hail and delivery fees, construction materials and potential food inflation (food‑bank demand and fertilizer‑shipment risks were cited).
- Taken together, markets are pricing in eased energy risk from the Hormuz announcement, but analysts warn full normalization of shipping and persistent, economy‑wide inflationary effects remain uncertain.
