TL;DR

Iran rejected key parts of the US peace proposal as "excessive and unrealistic" on Thursday, reversing Wednesday's euphoric rally. The S&P 500 pulled back 0.38%, the Dow shed 313 points, and oil stabilized near $95 (WTI) and $100 (Brent) after briefly trading much lower on deal optimism.

What Happened: Iran Pushes Back on Hormuz Deal Terms

The US-Iran war (officially begun February 28, 2026, under the designation Operation Epic Fury) has effectively shut the Strait of Hormuz, the narrow waterway through which roughly 20 percent of the world's daily oil and gas trade normally flows. Oil prices peaked at $126 per barrel last week, their highest since 2022, as the prolonged closure strained global energy supply.

On Wednesday, May 6, Axios reported that the US believed it was nearing a 14-point memorandum of understanding with Iran, covering both a ceasefire framework and a pathway to nuclear talks. Oil plunged more than 9 percent and stock indices surged to all-time highs.

Thursday brought a sharp reality check:

  • Iran's Foreign Ministry spokesman Esmaeil Baqaei confirmed Iran was still reviewing US messages delivered via Pakistani mediators but had not sent any formal reply.
  • Senior Iranian official Mohsen Rezaee (Expediency Council) said Tehran "will not allow the US to reopen the Strait of Hormuz with an unrealistic plan" and insisted the US must pay reparations for war damage before any deal.
  • Iran's semi-official ISNA agency reported that part of the US proposal "contains excessive and unrealistic proposals which have been strongly rejected by our country's authorities."
  • Trump said the Iranians "want to make a deal very much" and at a Wednesday evening event predicted the war "will be over quickly."
  • The White House launched its Project Freedom initiative (a plan to guide commercial vessels out of the Persian Gulf through the Strait), then paused it within 24 hours, citing progress in negotiations, leaving the situation unresolved.

Why Markets Moved on Iran Deal Uncertainty

Wednesday's market surge was driven by a single catalyst: the prospect of Hormuz reopening and global energy costs returning toward pre-war levels. When Iran signaled Thursday that the US proposal fell short of its demands, that optimism unwound quickly.

Oil recovered from its intraday session lows. WTI crude settled at $94.81 per barrel, down just 0.28% on the day. Brent, the global benchmark, closed at $100.06, falling 1.19%. Both had briefly traded meaningfully lower before Iranian officials spoke.

Equities followed oil's direction. The S&P 500 fell 0.38% to close at 7,337.11, after touching a new all-time intraday high earlier in the session. The Nasdaq Composite slipped 0.13% to 25,806.20. The Dow Jones Industrial Average fell 313 points (0.63%), settling at 49,596.97. Amazon, Broadcom, and Micron were among the larger drags on the day.

Not all stocks sold off. Fortinet surged 20% after raising its full-year billings guidance. After the close, Airbnb reported Q1 2026 revenue of $2.7 billion (up 18% year-over-year) and raised its full-year outlook to "low to mid-teens" growth, pointing to resilient travel demand despite macro headwinds.

Implications for Traders Watching Oil, Stocks, and Futures

Stock traders: The market is navigating two opposing forces. A strong earnings season and relentless AI demand have pushed indices to record highs, while sustained oil prices above $90 add inflation risk that can compress profit margins and consumer spending. Sector rotation matters: energy stocks benefit when deal optimism fades; technology and consumer discretionary face the most headwind from elevated energy costs.

Futures traders: Oil futures remain the most sensitive instrument to every Iran headline. The implied range between a deal scenario and a collapse scenario in crude is unusually wide, perhaps $30 to $40 per barrel, making positioning around news events high-risk. Position sizing and stop discipline are critical when a single statement from Tehran can move WTI by 5 to 10 percent in a session.

Energy and commodity traders: Natural gas prices have also soared since Hormuz was effectively closed. Strait reopening would normalize LNG shipping flows over several weeks, not overnight, meaning even a successful deal would be a gradual process rather than an immediate price reset. Traders pricing in a "deal done" scenario should factor in that reopening timeline.

Potential Positives vs Negatives

Positives:

  • Trump said Iranians "want to make a deal very much," suggesting Washington still sees a path to resolution.
  • Iran has not formally rejected talks. It is still reviewing the US proposal through Pakistani mediators, meaning the back-channel remains open.
  • A successful deal would send oil sharply lower, relieve inflationary pressure, and likely deliver a significant boost to equity markets globally.
  • The broader bull run, supported by strong earnings and AI sector demand, provides a market floor that is independent of the Iran situation.

Negatives:

  • Iran explicitly called key US terms "unrealistic" and is demanding war reparations, which represent significant sticking points not easily resolved in days.
  • The Strait of Hormuz remains closed. Every additional week of closure adds cumulative damage to global shipping flows, energy supply, and inflation data.
  • Oil at $95 to $100 per barrel is still high enough to weigh on growth, and a breakdown in talks could quickly return prices toward $110 to $120.
  • Trump's Project Freedom reversal, launching and then pausing the Hormuz navigation operation within 24 hours, adds uncertainty around US strategic intent.

What Could Happen From Here: Three Scenarios Over the Next 24-72 Hours

Base case (roughly 50%): Talks continue quietly via Pakistani intermediaries through the weekend. No major breakthrough is announced publicly. Oil stays rangebound between $90 and $103. Stocks drift sideways to modestly lower, with the earnings season providing a cushion. The S&P holds above 7,200.
Confirm: No dramatic Iranian or White House statement; oil fails to break above $103 on a sustained basis.
Invalidate: Iran publicly rejects the entire US framework at the supreme-leader level, or Trump announces military escalation.

Upside case (roughly 25%): Iran sends a formal counter-proposal or a positive signal emerges from the Pakistani back-channel. Trump announces tangible progress. Oil drops toward $85 to $90 and stocks surge back to fresh all-time highs, with the Dow recapturing 50,000.
Confirm: An Iranian foreign ministry statement welcoming further talks, or a credible report of a counter-proposal submitted.
Invalidate: Iranian hardline voices dominate the public messaging cycle with no softening.

Downside case (roughly 25%): Iran formally rejects the US framework. Trump signals escalation or reinstates Project Freedom unilaterally. Oil climbs back above $105 to $110, and US stocks sell off 1 to 2% with bond yields rising on renewed inflation concerns.
Confirm: A statement from Supreme Leader Khamenei rejecting the deal, or credible reports of resumed US military activity near the strait.
Invalidate: Back-channel messaging keeps talks alive despite tough public posturing from both sides.

What Traders Should Watch Next (24 Hours)

  • Any statement from Iran's Foreign Ministry or Supreme Leader Khamenei on the status of US talks.
  • Brent crude overnight: a sustained move above $103 to $105 signals deal optimism is fading further.
  • Trump's Truth Social posts or White House press statements on Iran negotiations.
  • S&P 500 futures pre-market Friday for the directional read into the weekly close.
  • Airbnb (ABNB) after-hours stock reaction, which may provide a lift to Nasdaq futures given the strong Q1 beat.
  • Any update on Project Freedom or Hormuz commercial shipping navigation status.

FAQ

What is the Strait of Hormuz and why does it matter for markets?
The Strait of Hormuz is a narrow waterway between Iran and Oman connecting the Persian Gulf to the Gulf of Oman. Roughly 20 percent of the world's daily oil and liquefied natural gas trade passes through it. Its effective closure since late February 2026 has been the primary driver of elevated global energy prices this spring.

What does Iran mean by demanding "reparations"?
Iranian officials have stated that the US must financially compensate Iran for military and infrastructure damage caused by Operation Epic Fury before a formal peace agreement can be signed. This is a significant condition the US has not publicly agreed to, and it represents one of the main obstacles to a deal.
