S&P 500 Hits New Record as Oil Drops After Iran Says Hormuz Is Open
The S&P 500 hit a new record after Iran said the Strait of Hormuz was open, and oil prices plunged.
On April 17 U.S. indexes jumped in early trading, with the S&P up about 0.8%, the Dow rising 678 points (1.4%) and the Nasdaq up roughly 1%. Oil plunged after Iran said the strait was fully open, with U.S. crude sliding about 10.8% to $81.28 a barrel and Brent falling about 10.3% to $89.13 intraday. That drop followed earlier easing: Brent had settled at $94.93 on April 15 after markets reacted to signs of a possible ceasefire and an "in principle" U.S.-Iran pause.
Early coverage framed the rally mainly as investor relief over a potential end to the Iran war and returning Gulf oil flows, a view reflected in PBS and CBS reporting earlier in the week. More recent accounts from Axios and PBS recast the story, saying the market jump was driven specifically by the Hormuz "open" announcements that sharply eased energy risk and knocked oil prices down. That shift underscores how sensitive markets remain to official statements about Strait of Hormuz traffic even before shipping fully normalizes.
The rally capped a rebound from a nearly 10% late-March correction; the S&P has climbed more than 10% in roughly two weeks. Investor optimism was reinforced by bank results such as Bank of America's $8.6 billion Q1 profit and Morgan Stanley's stock jumping 4.5% on stronger earnings. Lower oil also eased inflation fears, sending the 10-year Treasury yield down from 4.32% to about 4.24% and lifting European markets. Market strategists on social media noted the resilience, with @philrosenn calling the record unsurprising after recent V-shaped recoveries. @minddriftdaily warned a failed deal could spark a historic crash, while @Forcenito_ estimated about a 55% chance of a bull case versus 45% for a bear scenario.
📌 Key Facts
- Between April 15–17, the S&P 500 rose about 0.8%, set fresh all‑time highs and extended a multi‑week winning streak after tumbling nearly 10% in late March and rebounding more than 10% in the following weeks.
- Markets rallied on investor optimism that the war with Iran could be winding down — regional officials reported an ‘in principle’ agreement to extend a ceasefire to allow diplomacy, and political comments (including President Trump saying the war “should be ending pretty soon”) reinforced that sentiment.
- The latest drop in oil was triggered by April 17 announcements that the Strait of Hormuz is ‘fully open’: U.S. crude plunged about 10.8 to roughly $81.28 and Brent fell about 10.3% to roughly $89.13 intraday.
- Earlier oil moves show partial easing of panic: Brent had settled at $94.93 on April 15 (well above pre‑war levels near $70) after peaking near $119 earlier in the conflict, illustrating volatility as shipping/flow prospects shift.
- Equity optimism and the S&P’s record were tied to the perceived easing of energy risk — Axios and other outlets noted markets are highly sensitive to official statements about the Strait of Hormuz and that such statements directly moved oil and stock markets.
- Fixed‑income and inflation expectations shifted: the 10‑year Treasury yield fell from about 4.32% to 4.24% as lower oil prices eased near‑term inflation concerns.
- Corporate earnings and stock movers supported the rally in places: Bank of America reported $8.6 billion in Q1 profit and cited a ‘resilient American economy,’ Morgan Stanley jumped about 4.5% on strong results, State Street and Fifth Third rose on beats — while Netflix fell roughly 11.5% despite strong profit because of weak guidance and board changes.
- Global market reaction was mixed by region: European indices leapt (CAC 40 about +2%, DAX about +2.2%) on the Hormuz announcement, whereas Asian markets, which had already closed, were down earlier.
- Some earlier AI‑related fears that hurt specific companies and private‑credit firms have eased, and certain AI‑exposed stocks have recovered portions of their 2026 losses as broader risk sentiment improved.
