TL;DR

Secretary of State Marco Rubio declared on Tuesday that Operation Epic Fury, the US military campaign against Iran launched in February, is concluded. As of approximately 6:00 p.m. ET on May 5, 2026, the US is now running a new defensive mission called Operation Project Freedom to escort neutral ships through a still-largely-closed Strait of Hormuz. US stocks closed at a record high on Tuesday. Oil pulled back sharply from Monday's four-year peak. Bond traders are ramping up bets that the incoming Warsh-led Federal Reserve could raise interest rates before cutting them.

What Happened: Operation Epic Fury Declared Over

At a White House press briefing on Tuesday, May 5, 2026, Rubio announced that Operation Epic Fury, the coordinated US-Israel campaign that launched in late February and included strikes on Iran's military facilities, nuclear sites, and leadership, has achieved its objectives.

"The operation, Epic Fury, is concluded. We achieved the objectives of that operation," Rubio told reporters. "This is the first step toward reopening the strait. We are doing it not only because we were asked, but because we are the only ones that can."

At a separate Pentagon briefing, Defense Secretary Pete Hegseth confirmed the ceasefire technically remains in effect despite ongoing skirmishes. He described the new Operation Project Freedom as a "temporary and defensive operation" to resume traffic through the international waterway. "We are not looking for a fight, but Iran cannot be allowed to block innocent countries and their goods from an international waterway," Hegseth said.

General Dan Caine, Chairman of the Joint Chiefs of Staff, laid out the scope of the current threat: since the ceasefire took effect roughly one month ago, Iran has fired on commercial vessels nine times, seized two container ships, and attacked US forces more than ten times. Caine described all of these incidents as "below the threshold of restarting major combat operations at this point."

More than 1,550 vessels remain trapped in the Persian Gulf, unable to transit. The situation will be formally reassessed on Friday, May 8.

Why Markets Moved

The Rubio declaration, confirmed in real time by multiple outlets including CNN, Reuters, the Los Angeles Times, Al Jazeera, and the Guardian, hit markets as a partial de-escalation signal. The read: the US is stepping back from active offensive strikes and focusing on securing passage for civilian ships. That is a meaningful shift in posture, even if the core problem, the closed strait, is not yet resolved.

US equities surged to a record closing high. Semiconductor and memory stocks led gains as risk appetite improved broadly. Brent crude, which had closed at $114.44 a barrel on Monday, its highest price in years after Iranian strikes on UAE targets, fell roughly 4% to around $109.87. WTI dropped approximately 3.9% to $102.27. Both benchmarks remain deeply elevated by historical norms.

The bond market told a more complicated story. The 30-year US Treasury yield briefly touched 5%, and traders continued to build wagers that the Federal Reserve, under incoming chair Kevin Warsh (expected to formally take over around May 15), could raise interest rates before eventually cutting them. The war-driven surge in oil prices has scrambled the Fed's rate outlook: where rate cuts were widely expected at the start of 2026, the market now prices in the possibility of a hike first.

Implications for Traders

Oil and Energy Futures Traders

The retreat from $114 Brent gives traders a partial exhale, but the strait remains functionally closed. More than 1,550 ships are still stuck. Saudi Arabia has cut its June official selling prices from a record-high May premium, signaling supply pressure is being felt upstream. Refinery and tanker freight markets remain distorted. The key question is whether Operation Project Freedom actually opens the strait or triggers another round of Iranian countermoves before Friday's review.

Equity and Index Futures Traders

The record close in US stocks reflects relief that the US is not escalating into a second offensive wave. Chipmakers and semiconductor names led because the AI infrastructure build cycle is sensitive to supply chain and energy cost assumptions. However, oil at $100-plus per barrel is still a significant cost and inflation headwind. If the strait remains closed and freight costs stay elevated, margin pressure on industrials and transport will mount into Q2 earnings.

Bond and Rates Traders

The Fed rate hike scenario is no longer a tail risk. Warsh has not yet made explicit policy commitments, but the combination of elevated oil prices, persistent supply-chain disruption from the Hormuz closure, and a structurally tighter global energy market puts upward pressure on inflation expectations. Traders buying the 30-year near 5% are locking in multi-year high yields, but if the inflation picture worsens, those positions could still be early.

Crypto Traders

Bitcoin and broader crypto markets have been tracking risk sentiment closely throughout the Hormuz crisis. The stock-market record close and oil pullback are risk-on signals that typically support crypto. However, rising rate-hike probabilities create a competing headwind: higher real rates generally weigh on speculative assets. Strategy Inc. (formerly MicroStrategy) remains the single largest institutional Bitcoin holder and reported a $12.5 billion Q1 loss, underscoring how sensitive leveraged crypto plays remain to macro repricing.

Potential Positives vs Negatives

Positives: The formal end of offensive operations reduces the near-term probability of a full-scale escalation spiral. US escort operations could begin to free some of the 1,550 trapped vessels, loosening the supply bottleneck over days or weeks. Oil-sensitive sectors, including airlines, shipping, and industrials, could see margin relief if Brent retreats further toward $90-95. Equity sentiment benefits from reduced war-risk premium.

Negatives: The strait is still largely closed. Iran has signaled it views Operation Project Freedom as a ceasefire violation, leaving open the risk of renewed attacks on escort vessels or tankers. Oil remaining above $100 sustains inflation pressure, reinforcing the Warsh Fed rate-hike scenario. Any incident involving US Navy ships before Friday's review could reverse the market rally sharply. Saudi Arabia posted its widest fiscal deficit since 2018, signaling OPEC+ finances are under strain with reduced buffer against disruption.

What Could Happen From Here

Base case (50-55%): Operation Project Freedom successfully escorts a partial convoy through the strait without major Iranian response. Brent stabilizes in the $100-110 range. Stocks hold near records. Warsh signals a hawkish but measured stance that calms rate-hike fears somewhat. Friday's review passes without restart of major combat. Progress toward a more durable diplomatic agreement begins. Confirms this path: Iranian restraint over the next 72 hours, US Navy escorts completing transit without incident, Brent closing below $110 by end of week.

Upside case (20-25%): Iran accepts the defensive framing, the strait reopens more fully under international pressure, and oil pulls back toward $90-95 quickly. This would be a significant macro tailwind: inflation pressure eases, rate-hike bets unwind, equities extend the record-high rally, and crypto stabilizes. Confirms: Iranian statement accepting free commercial passage, sharp drop in Brent below $100, VIX declining into the mid-teens.

Downside case (20-30%): Iran fires on US escort vessels or seizes a tanker during Operation Project Freedom, triggering renewed military exchange. Brent spikes back above $120 or higher. The Friday review is suspended and offensive operations resume. Stocks reverse the record high and test prior support levels. The Fed is forced to weigh a stagflation scenario explicitly. Invalidates base case: Confirmed Iranian attack on US or allied military assets, Brent break above $115 with volume, emergency White House statement before May 8.

What to Watch Next (Next 24-72 Hours)

  • Friday, May 8 review: The US will formally reassess the Hormuz situation. Any statement from the Pentagon or State Department ahead of that deadline will move markets.
  • Iranian response to Operation Project Freedom: Watch for IRGC statements or naval movements in the strait as the first US escort convoys attempt transit.
  • Oil: Brent $110 level: A sustained break below here would signal the market is pricing in a meaningful reopening. A reversal back above $114 would signal renewed concern.
  • 30-year Treasury yield and Fed futures: Kevin Warsh's first public comments as Fed chair will reset rate-hike expectations significantly in either direction.
  • Trapped vessel count: Any confirmed reduction below 1,550 ships is a real signal the strait is opening. No change or an increase signals the diplomatic situation has not improved.

FAQ

What was Operation Epic Fury? Operation Epic Fury was the US-Israel military campaign launched in late February 2026 targeting Iran's military facilities, nuclear program, and senior leadership. The operation resulted in the death of Supreme Leader Ali Khamenei and triggered Iranian retaliatory strikes on Israeli cities and US military bases across the Gulf region.

Why does the Strait of Hormuz matter to markets? The Strait of Hormuz is a narrow waterway between Iran and Oman through which roughly 20% of global oil trade normally flows. Iran's effective closure of the strait since the ceasefire has trapped over 1,550 ships and pushed Brent crude to its highest price in years, adding inflationary pressure globally.
