TL;DR

American and Iranian negotiators say they have a draft agreement to extend the ceasefire and gradually reopen the Strait of Hormuz. But neither President Trump nor Iran's Supreme Leader Khamenei has approved it. CENTCOM simultaneously called an overnight Iranian strike an "egregious ceasefire violation." Stocks are at session highs on deal optimism. Brent crude is pulling back toward $93. Bitcoin is holding near a five-week low around $73,000 to $75,000. The gap between market positioning and an unsigned deal creates real afternoon risk.

What Happened

As of 2:13 p.m. ET on May 28, negotiators on both sides believe they have a draft deal that would formally extend the ceasefire for 60 days and create a timeline for gradually reopening the Strait of Hormuz to commercial shipping. ABC News, citing two U.S. officials and a source involved in the mediation, reported the agreement has not been signed. Neither Trump nor Supreme Leader Mojtaba Khamenei has given final approval.

ABC News noted that both sides have rejected agreements at late stages in prior rounds. Trump told mediators he wants a few more days to make the final call, according to Axios.

Adding tension to the picture, U.S. Central Command issued a statement describing an overnight Iranian strike on a U.S. military facility as an "egregious ceasefire violation." A separate U.S. source confirmed to ABC News that the ceasefire remains technically in force. Trump has previously described similar exchanges as a "love tap." He also said, when asked about the ceasefire's future, that "the world will know when the ceasefire is over" when it sees "one big glow coming out of Iran."

This follows a three-month conflict that began February 28 with joint U.S.-Israeli strikes on Iranian military, government, and infrastructure sites. A two-week ceasefire was announced in April. Initial talks in Pakistan failed. The ceasefire was later extended open-endedly, with U.S. blockade measures continuing through the Strait of Hormuz.

Iran Deal Hopes Drive Markets: Why Stocks and Oil Moved

Equities reversed earlier session losses after the Axios ceasefire extension report circulated in late morning. The Nasdaq gained approximately 0.64% and the S&P 500 climbed roughly 0.49% into the afternoon session, per TheStreet. Both indices are trading near session highs.

Brent crude gave up earlier gains and fell to about $93.56 per barrel as of 12:43 p.m. ET, down 0.8% on the day, according to Reuters. West Texas Intermediate held near $88.66. Oil had traded above $100 earlier this week when strikes resumed, meaning the pullback from those highs has been sharp.

Bitcoin held near a five-week low in the $73,000 to $75,000 range, according to Bloomberg and Coinbase data. Spot Bitcoin ETFs logged $733 million in daily outflows on Thursday, bringing the monthly total to over $2 billion. ETH spot ETFs have posted 11 consecutive days of outflows.

Dell Technologies rose about 6.7% intraday, extending a 139% year-to-date gain, ahead of its fiscal Q1 2027 earnings report expected after today's close. Analysts and markets are watching for AI server demand guidance, which has been a primary driver of the stock's run.

Implications for Traders

Equities and Index Futures

The afternoon session is positioned for a deal that has not yet been formally signed. Any Trump statement signaling he wants more concessions or that the current terms are unacceptable could trigger a quick reversal in index futures. Traders should be cautious about adding to long positions near session highs ahead of a binary geopolitical event.

Oil and Energy Futures

Brent crude is now more than $6 below its intraday peak from earlier this week. The current level prices in meaningful progress toward a deal. If talks collapse, Brent would likely retest the $97 to $100 range. A confirmed sign-off, especially with a visible Hormuz reopening timeline, could push Brent toward $85 or below. Oil remains the most sensitive single asset to any headline shift in this conflict.

Crypto

Bitcoin's correlation with risk assets has been elevated throughout the Iran conflict. The current divergence, where stocks are rising but BTC remains near multi-week lows, reflects institutional ETF selling pressure that is partly separate from the geopolitical headline. A deal collapse that hits equities would likely push Bitcoin back toward $70,000 support. A confirmed deal could help BTC recover toward the $78,000 area as risk appetite improves and ETF outflows slow.

Potential Positives vs Negatives

Positives:

  • A signed deal would reopen the Strait of Hormuz, easing energy inflation pressure that has been flowing into core PCE and frustrating the Fed's path to rate cuts.
  • Oil falling into the $80s would provide relief for consumers, reduce input costs for companies, and remove a key inflation risk premium from bond markets.
  • Risk assets, including equities and crypto, could reprice higher as the geopolitical discount narrows.

Negatives:

  • Trump has walked away from late-stage deals before, and his "maximum pressure" framing suggests he may demand stronger terms.
  • CENTCOM's "egregious violation" language could be used as justification to pause or cancel negotiations.
  • Iran's Supreme Leader also faces domestic political constraints that make a final sign-off uncertain. A breakdown would spike oil, hit equities, and likely push BTC back below $72,000 support.

What Could Happen From Here

Base case (roughly 50%): Trump takes several days to review the draft. Markets stay in a volatile holding pattern, with oil trading between $90 and $96. Stocks hold current gains but do not break materially higher or lower. No resolution today before the close. Confirmation: no White House announcement before 4 p.m. ET. Invalidation: any Trump statement signaling an imminent decision.

Upside case (roughly 25%): Trump signals he will sign or formally approves the deal by end of week. Oil drops to the low $80s. S&P 500 pushes to fresh record closes. Bitcoin recovers above $78,000 as institutional ETF flows turn positive. Confirmation: formal Axios, AP, or Reuters report that both leaders have approved. Invalidation: Trump posts publicly that the deal is insufficient.

Downside case (roughly 25%): Trump rejects the draft, citing the CENTCOM violation or demanding stricter nuclear terms. Iran responds with a symbolic strike. Brent spikes back above $100. S&P futures drop 1% to 2% in after-hours trading. Bitcoin retests $70,000. Confirmation: White House statement calling the deal unacceptable or new strike orders issued. Invalidation: both sides return to the table with revised terms within 24 hours.

FAQ

Why are stocks rallying if the Iran deal isn't confirmed?
Markets frequently price in the probability of an event before it is finalized. The Axios report created enough confidence for traders to reduce their war-risk hedges, particularly in oil. The risk is that this optimism is priced in ahead of a final decision that could go either way.

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 through which roughly 20% of the world's traded oil passes. When traffic through it is disrupted or blocked, global energy prices rise sharply. The current U.S. blockade has contributed to oil staying elevated above $90 per barrel since the conflict began.
