S&P 500 & Nasdaq 100 Hit All-Time Highs
as Iran Peace Hopes and Strong Earnings Fuel Rally
By Felixsr Β· April 15, 2026 Β· 6 min read Β· Economics
US stocks closed at all-time highs on Wednesday, April 15, as two powerful forces converged: growing optimism that the US-Iran ceasefire will be extended and a broader peace deal reached, and a strong start to the Q1 earnings season headlined by major bank beats. The S&P 500 surpassed its previous all-time high of 7,002.28 set on January 28 β confirming that the war-driven selloff has been fully reversed.
The rally was broad but tech-led. The Nasdaq 100 climbed 1.4% to a new record, software stocks surged roughly 4%, Tesla jumped over 7% on an AI chip update, and quantum computing stocks spiked on an Nvidia technology announcement. Meanwhile, oil dropped 7% to $91/barrel β a meaningful tailwind for inflation expectations and Federal Reserve rate-cut hopes.

Two Things Drove Today’s Rally
1. Iran Ceasefire Extension Hopes β Oil Tumbles 7%
Early in the session, AP reported that the US and Iran are close to agreeing on extending their two-week ceasefire and resuming talks toward a longer-term peace deal. President Trump added fuel by telling Fox Business that the Iran war is “very close to over” and that Tehran is “very desperately” seeking a deal.
Oil markets responded sharply. WTI crude fell 7% to around $91/barrel, while Brent dropped 4% to ~$95. Lower oil prices ease inflation fears, reduce pressure on the Federal Reserve to hike rates, and improve consumer spending power β a triple tailwind for equities.
The White House spokesperson pushed back on reports that the US proactively requested a ceasefire extension, calling them inaccurate. No formal deal has been announced. The 2-week ceasefire expires on April 21 β that remains the next key date.
2. Earnings Season Is Off to a Strong Start
Bank of America and Morgan Stanley both reported Q1 results today, with equity trading revenue coming in well above expectations. JPMorgan had already delivered a 13% profit increase the prior day. ASML, which makes photolithography machines critical for AI chip production, also reported strong quarterly numbers driven by AI-related demand.

What Wall Street Is Saying
“The stock market is currently reflecting the view that the Iran war is essentially over.”
“Markets don’t wait for perfect information. While uncertainty around energy supply disruptions remains, the overall risk is diminishing.”
“Signs of easing tensions in the Middle East lifted risk appetite, and the drop in oil prices helped alleviate inflation concerns.”
“Examples from history are not favorable for the view of a quick resolution coming from the peace talks. Given the wide gap between the fundamental demands of the US and those of Iran, it’s hard to see a resolution opening the Strait of Hormuz within the two-week time frame.”
What to Watch Next
Markets are already pricing in a significant amount of Iran war resolution. That means the next moves are asymmetric:
- April 21 β 2-week ceasefire expires. Extension or deal = further rally. Breakdown = short-term pullback
- Weekend talks β Second round of US-Iran negotiations expected in Pakistan
- Oil price trajectory β WTI at $91 is already close to pre-war levels. If Hormuz fully reopens, oil could test $80
- Earnings flow β Big tech reports coming: watch for AI spending guidance
Today’s rally represents the market’s collective bet that the Iran war is winding down and AI-driven corporate earnings growth is intact. Both may be right β but with the ceasefire expiring on April 21, the next week will confirm or challenge that thesis. Stay watchful.
