Oil prices surged and U.S. stock futures declined as global markets reacted to American airstrikes on Iranian nuclear facilities, according to the Associated Press.
Brent crude oil, the international standard, rose 2.6 percent to $79 per barrel, while U.S. crude climbed 2.6 percent to $75.76 per barrel.
Why It Matters
The U.S.'s strikes on Saturday marked its entry into the Iran-Israel conflict and were the biggest escalation in the war since Israel first ignited it by striking at Iran on June 13.
Iranian lawmakers voted to support closing the Strait of Hormuz in response to the strikes, which hit three Iranian nuclear and military sites. A final decision on the matter rests with Iranian Supreme Leader Ayatollah Ali Khamenei.
Nearly 20 percent of global oil trade passes through the Strait or Hormuz, a narrow but highly strategic waterway connecting the Persian Gulf to the Gulf of Oman and the Arabian Sea.
At its narrowest point, the strait is about 21 miles wide, with two shipping lanes that are 2 miles wide in each direction. Any closure of the channel is likely to result in a global spike in oil prices.
What To Know
There was some market uncertainty on Sunday evening, with futures for the S&P 500 and Dow Jones Industrial Average slipping 0.3 percent, while Nasdaq futures fell 0.5 percent.
Treasury yields remained little changed. The modest moves suggest markets are taking the latest developments in stride, though analysts expect continued volatility as the situation develops.
Iran's strategic position controlling the Strait of Hormuz gives the country significant leverage over global energy markets. However, any Iranian retaliation that includes closing the waterway would likely be difficult to execute.
Traders remain concerned that Iran could severely disrupt transit through the strait, potentially sending insurance rates spiking and making shippers nervous to move cargo without U.S. Navy escorts.
Complicating Iran's decision is the country's own dependence on the waterway.
Iran uses the strait to transport its own crude oil, mostly to China, and oil represents a major revenue source for the regime, creating economic incentives against closure.
What People Are Saying
President Donald Trump wrote on Truth Social on Saturday evening: "ANY RETALIATION BY IRAN AGAINST THE UNITED STATES OF AMERICA WILL BE MET WITH FORCE FAR GREATER THAN WHAT WAS WITNESSED TONIGHT. THANK YOU! DONALD J. TRUMP, PRESIDENT OF THE UNITED STATES."
Greg Kennedy, director of the Economic Conflict and Competition Research Group at King's College London, told Newsweek: "This is not an act that just stays in the Gulf region, it has wider global strategic ripples."
Jorge León, head of geopolitical analysis at energy consultancy Rystad, told the Financial Times on Sunday: "In an extreme scenario where Iran responds with direct strikes or targets regional oil infrastructure, oil prices will surge sharply. Even in the absence of immediate retaliation, markets are likely to price in a higher geopolitical risk premium."
Spencer Hakimian, founder of Tolou Capital Management, wrote on X, formerly Twitter, on Saturday: "There are close to 50 large oil tankers scrambling to leave the Strait of Hormuz right now. Looks like the oil industry is expecting the Strait to be blockaded in the coming days."
The New York Stock Exchange (NYSE) stands in lower Manhattan on June 18, 2025 in New York City. Traders are looking ahead to the Federal Reserve's monetary policy decision later today.

Markets will closely monitor Iran's response as trading opens Monday, with analysts remaining divided on the likelihood of strait closure.
The final decision about Iran's response will be made by Khamenei; the parliament's vote to close the strait merely advises him of the option to pursue.

What is the Strait of Hormuz and why is it so significant?
While there have been no major disruptions to the global oil supply so far, the attacks on Iran – by Israel and then the US – have rattled investors, sending oil futures soaring by around 10%, among fears Iran could retaliate by disrupting shipping in the Strait of Hormuz. From the perspective of the global economy, there are few places as strategically important. The waterway, located between the Persian Gulf and the Gulf of Oman, is only 21 miles wide at its narrowest point. It's the only way to ship crude from the oil-rich Persian Gulf to the rest of the world. Iran controls its northern side. About 20 million barrels of oil, about one-fifth of daily global production, flow through the strait every day, according to the US Energy Information Administration (EIA), which called the channel a 'critical oil chokepoint.' On Sunday evening, following US airstrikes on three of Iran's nuclear facilities, Brent crude, the global benchmark, briefly surged above $80 per barrel, according to Refinitiv data, the first time that's happened since January. Before the conflict, prices had largely hovered between $60 and $75 a barrel since August 2024. Brent last traded at $78.2 per barrel, while WTI, the US benchmark, was at $75.06. Whether oil prices will climb further now depends on Iran's response. Rob Thummel, senior portfolio manager at energy investment firm Tortoise Capital, told CNN that a potential disruption to the Iran-controlled sea route would cause oil prices to surge toward $100 per barrel. A functioning Strait of Hormuz is 'absolutely essential' to the health of the global economy, he said. A prominent adviser to Iran's supreme leader, Ayatollah Ali Khamenei, has already called for the closure of the Strait. 'Following America's attack on the Fordow nuclear installation, it is now our turn,' warned Hossein Shariatmadari, the editor-in-chief of the hardline Kayhan newspaper, a well-known conservative voice who has previously identified himself as a 'representative' for Khamenei. Geographic leverage over global shipping gives Iran the 'capacity to cause a shock in oil markets, drive up oil prices, drive inflation, collapse Trump's economic agenda,' Mohammad Ali Shabani, an Iran expert and editor of the Amwaj news outlet, told CNN. When it comes to moving oil, the Strait is actually much narrower than its 21-mile official width. The navigable shipping lanes for massive supertankers are only about two miles wide in each direction, requiring vessels to pass through both Iranian and Omani territorial waters. But Vandana Hari, founder and CEO of Vanda Insights, which tracks energy markets, sees Iran's blocking of the Strait as a 'remote tail risk.' The presence of a beefed-up US naval fleet in the region is both a deterrent and a response tool, she said. 'Iran has a lot to lose and very little, if anything, to gain by attempting to close the Strait,' Hari said. 'Iran cannot afford to turn its oil-producing neighbors, who have been neutral or even sympathetic towards the Islamic Republic as it faced Israeli and US attacks, into enemies, any more than trigger the ire of its main crude market, China.' A closure of the Strait would be particularly detrimental to China and other Asian economies which rely on the crude oil and natural gas shipped through the waterway. The EIA estimates that 84% of the crude oil and 83% of the liquefied natural gas that moved through the Strait of Hormuz last year went to Asian markets. China, the largest buyer of Iranian oil, sourced 5.4 million barrels per day through the Strait of Hormuz in the first quarter this year, while India and South Korea imported 2.1 million and 1.7 million barrels per day, respectively, according to the EIA's estimates. In comparison, the US and Europe imported just 400,000 and 500,000 barrels per day, respectively, in the same period, according to the EIA. On Sunday, India's Minister for Petroleum and Natural Gas Hardeep Singh Puri sought to reassure jittery investors on X that the country has 'diversified' its oil supplies in the past few years. On Sunday, India's Minister for Petroleum and Natural Gas Hardeep Singh Puri said on X that the country has 'diversified' its oil supplies in the past few years. 'A large volume of our supplies do not come through the Strait of Hormuz now. Our Oil Marketing Companies have supplies of several weeks and continue to receive energy supplies from several routes,' he said. 'We will take all necessary steps to ensure stability of supplies of fuel to our citizens.' CNN's John Towfighi, Nadeen Ebrahim, and Rhea Mogul contributed reporting.

The Latest: Trump muses about regime change in Iran after U.S. strikes on nuclear facilities
Israel's military said Monday it was striking around Iran's western city of Kermanshah, as fears of a wider regional conflict loomed large after the United States inserted itself into Israel's war by attacking Iranian nuclear sites. The operation raised urgent questions about what remained of Tehran's nuclear program and how its weakened military might respond. The price of oil rose as financial markets reacted. Iran lashed out at the U.S. for crossing 'a very big red line' with its risky gambit to strike the three sites with missiles and 30,000-pound bunker-buster bombs . President Donald Trump, who has warned of additional strikes if Tehran retaliates against U.S. forces, has mused about the possibility of 'regime change ″ in Iran, despite administration officials earlier indicating they wanted to restart talks with Iran. U.S. Secretary of State Marco Rubio, in an interview with CBS, said: 'Let's meet directly.' Ali Akbar Velayati, an adviser to Iran's supreme leader, said any country used by the U.S. to strike Iran 'will be a legitimate target for our armed forces,' the state-run IRNA news agency reported. Tens of thousands of American troops are based in the Middle East. Here is the latest: North Korea condemns U.S. strikes on Iran North Korea says it 'strongly condemns' the U.S. attack on Iranian nuclear facilities, calling it an egregious violation of Iran's territorial integrity and security interests. North Korea's Foreign Ministry said in a statement Monday that the United States and Israel were escalating tensions in the Middle East through the use of military force, and called on the 'just-minded international community' to raise a unified voice against their 'confrontational behavior.' During his first term, U.S. President Donald Trump met North Korean leader Kim Jong Un three times in 2018 and 2019, but their diplomacy collapsed over disagreements in exchanging the release of U.S.-led sanctions against North Korea and the North's steps to wind down its nuclear and missile program. Kim has since accelerated his arms development while ignoring talk offers by Washington and Seoul. He has shifted the priority of his foreign policy to Russia, sending thousands of troops and huge shipments of military equipment to fuel Russian President Vladimir Putin's war on Ukraine. Trump claims 'monumental damage' inflicted on Iranian nuclear sites President Donald Trump asserted on his Truth Social platform that Iran's nuclear sites sustained 'monumental damage' in the American attack, though a U.S. assessment on the strikes is still underway. 'The biggest damage took place far below ground level. Bullseye!!!' he wrote. U.S. defense officials have said they are working to determine about just how much damage the strikes did. Iran as well has not said how much damage was done in the attack, though Tehran has not offered any details so far on the strikes it has faced from Israel in its war with that country. Iran likely filled in tunnels at nuclear sites ahead of U.S. strikes An analysis of satellite photos by a nuclear nonproliferation group based in Washington shows Iran likely filled in tunnels at its nuclear site at Isfahan ahead of U.S. strikes early Sunday. The Washington-based Institute for Science and International Security published satellite images taken by Airbus it assessed showed trucks dumping soil into tunnels at the site on Friday. The U.S. attack likely targeted the tunnel entries, the group said. 'At least three of the four tunnel entrances are collapsed,' it said. 'The status of the fourth one is unclear.' Error!
