(NEW YORK) — Stocks closed mixed in volatile trading on Thursday after President Donald Trump delivered a televised address vowing to hit Iran “extremely hard” over the coming weeks.
The Dow Jones Industrial Average closed down 60 points, or 0.1%, after opening down by 600 points, while the S&P 500 ticked up 0.1. The tech-heavy Nasdaq increased 0.1%.
Each of the major indexes tumbled more than 1% in early trading, but they quickly recovered most or all of those losses.
The rollercoaster trading followed losses across Asian and European markets. Tokyo’s Nikkei 225 index slipped 2.3% and the pan-European STOXX 600 fell 0.6%.
Oil prices, meanwhile, surged as traders feared a persistent supply shortage amid the ongoing U.S.-Israeli war with Iran. U.S. oil prices climbed more than 10% on Thursday, registering about $111 a barrel.
Gasoline prices in the U.S. ticked up to $4.08 on average per gallon, marking a leap of $1.09 over the past month, AAA data showed.
Speaking at the White House on Wednesday, Trump voiced mixed messages about his plans for the Middle East conflict. He said Iran is no longer a threat to the U.S. and the war in Iran is “nearing completion.” However, he added, the U.S. plans to continue striking Iran over the next two or three weeks.
“We’re going to bring them back to the stone ages where they belong,” Trump said.
The trading volatility on Thursday interrupted an upswing for markets earlier in the week. On Tuesday, the Dow Jones Industrial Average soared more than 1,100 points, adding another 220 points on Wednesday as traders anticipated Trump may signal an off-ramp from the war in his evening remarks.
Since the war with Iran began on Feb. 28, Trump has issued conflicting signals about the expected duration of the war. On several occasions, stocks have climbed or fallen as markets weighed the implications of Trump’s comments.
The war prompted Iran’s effective closure of the Strait of Hormuz, a maritime trading route that facilitates the transport of about one-fifth of the global oil supply.
The vast majority of fuel delivered through the strait is bound for Asia, placing the heaviest pressure on energy supply in that continent. Since oil and gas are sold on a global market, however, the shortage has sent prices rising for just about everyone.
On Wednesday night, Trump urged other countries to take responsibility for reopening the strait.
“The countries of the world that do receive oil through the Hormuz Straight must take care of that passage,” Trump said. “We will be helpful, but they should take the lead in protecting the oil that they so desperately depend on.”
A potential U.S. exit from the war without ensuring that the strait is open could cast uncertainty over the path to a resumption of normal tanker traffic and a remedy for the current global oil shortage.

(WASHINGTON) — President Donald Trump on Thursday slapped 100% tariffs on some pharmaceutical products, ramping up his effort to boost U.S. drug manufacturing.
The move, in the form of an executive order, targets patented drugs that lack a “most favored nations” pricing agreement with the U.S. Under such agreements, companies ensure the U.S. will pay the same amount that other wealthy countries pay for similar medications.
Companies face a reduced levy if they agree to bring production to the U.S. or enter into pricing deals with the administration, the executive order says.
If companies commit to bring their manufacturing to America, then the tariff on their products will drop to 20%, the order notes.
In the event such companies also enter into a most-favored-nation agreement with the Department of Health and Human Services, then they can avert tariffs entirely while in the process of building a U.S.-based plant, according to the executive order.
Large companies, the executive order says, will receive a 120-day phase-in period before the tariffs take effect.
The fresh round of tariffs will exclude drugs made in some countries that previously entered into trade agreements with the U.S., including Switzerland, Japan, South Korea and the 27-member European Union, according to the order.
Pharmaceutical products from those countries will face a 15% tariff based on the terms of trade agreements reached with the U.S, the order notes.

(NEW YORK) — Mortgage rates have climbed to their highest level since September as fallout from the Iran war ripples through financial markets, Freddie Mac data on Thursday showed.
The average interest rate for a 30-year fixed-rate mortgage jumped to 6.46%, continuing a weeks-long surge since the war began on Feb. 28, during which time mortgage rates have increased nearly half a percentage point.
Mortgage rates remain slightly lower than this time a year ago, when the average rate for a 30-year fixed mortgage stood at 6.64%.
The recent spike in borrowing costs risks further strain on U.S. households as they weather elevated gasoline prices.
The rise in mortgage rates owes to a jump in U.S. Treasury yields as investors fear a bout of inflation in response to the Middle East conflict.
High bond yields make borrowing more expensive for average Americans, since 10-year Treasury rates influence the rates offered for a variety of loans, including mortgages and credit cards.
Since bonds pay a given investor a fixed amount each year, the specter of inflation risks higher consumer prices that would eat away at those annual payouts. In turn, bonds often become less attractive in response to economic turmoil. When demand falls, bond yields rise.
The yield on a 10-year Treasury bond, meaning the amount paid to a bondholder annually, stands at about 4.31%, about 0.35 percentage points higher than pre-war levels.
“Mortgage rates have risen as bond market yields have sought to price in the risk of higher inflation in the future,” Mark Hamrick, senior economic analyst at Bankrate, previously told ABC News.
Last week, bond yields soared close to levels reached in the aftermath of President Donald Trump’s “Liberation Day” tariffs in April 2025, when the 10-year Treasury yield peaked at around 4.5%.
Bond yields eased in recent days as Trump signaled a possible off-ramp from the war with Iran.

(NEW YORK) — Stocks tumbled worldwide on Thursday after President Donald Trump delivered a televised address vowing to hit Iran “extremely hard” over the coming weeks.

(NEW YORK) — The Dow Jones Industrial Average soared more than 950 points on Tuesday after President Donald Trump appeared to suggest the U.S. may end the Iran war without reopening the Strait of Hormuz.
In a post on social media, Trump indicated that the task of reopening the strait may fall to other countries, urging them to “go to the Strait, and just TAKE IT.”
The Dow jumped 970 points, or 2.1%, by early afternoon, while the S&P 500 climbed 2.4%. The tech-heavy Nasdaq increased 3.4%.
Since the U.S.-Israeli war with Iran began on Feb. 28, Trump has voiced mixed messages about the expected duration of the war. On several occasions, markets have climbed after traders interpreted comments from Trump as a potential off-ramp from the Middle East conflict.

A potential U.S. exit from the war without ensuring that the strait is open could leave uncertain the path to a resumption of normal tanker traffic and a resulting remedy for the current global oil shortage.
Global oil prices surged more than 5% on Tuesday, exceeding $118 a barrel, just shy of its highest price since 2022.
Gas prices in the United States topped $4 per gallon on average Tuesday, underscoring the link between rising oil prices and strained consumers.

(NEW YORK) — Gas prices in the United States topped $4 per gallon on average Tuesday, crossing the milestone for the first time in nearly four years, just weeks after the U.S.-Israeli war on Iran set off a global oil shock and spiked fuel costs.
Prices at the pump have soared more than 30% since the war began on Feb. 28., AAA data showed. Fuel costs last exceeded $4 a gallon in August 2022 following the Russian invasion of Ukraine.
The Middle East conflict prompted Iranian closure of the Strait of Hormuz, a maritime trading route that facilitates the transport of about one-fifth of global oil supply. The risk of a prolonged oil shortage triggered a surge in crude prices.
The U.S. is a net exporter of petroleum, meaning the country produces more oil than it consumes. But since oil prices are set on a global market, U.S. prices move in response to swings in worldwide supply and demand.
Global oil prices hovered around $104 a barrel on Tuesday, which amounted to a nearly 50% price leap from pre-war levels.
Crude oil is the main ingredient in auto fuel, accounting for more than half of the price paid at the pump, according to the federal U.S. Energy Information Administration.
Fatih Birol, the executive director of the International Energy Agency (IEA), earlier this week said the current oil crisis had surpassed the combined effect of worldwide energy shocks in the 1970s.
The global economy faces a “major, major threat,” Birol said at an event in Canberra, Australia, noting that no country would be “immune to the effects of this crisis if it continues to go in this direction.”
Member nations of the IEA announced two weeks ago that they plan to release 400 million barrels of oil from its strategic reserve, marking the largest oil release in the 32-nation group’s history.
The Trump administration is set to carry out the second-largest-ever delivery from the nation’s emergency reserve, which will make up nearly half of the IEA’s planned release. Trump also eased sanctions on Russian oil and suspended a key regulation of domestic oil transport. The president has also sought to restore tanker traffic in the Strait of Hormuz.

(NEW YORK) — Stocks closed significantly lower on Friday as the U.S.-Israeli war with Iran showed little sign of an imminent resolution that would end one of the worst global oil shocks in decades.
The Dow Jones Industrial Average plunged 790 points, or 1.7%, while the S&P 500 fell 1.6%. The tech-heavy Nasdaq dropped 2.1%.
The session on Friday marked the end of a woeful week for the major stock indexes. The Dow declined 1% this week, while the S&P 500 fell 2%. The Nasdaq decreased 3%.
Late Thursday, President Donald Trump postponed U.S. attacks on power plants in Iran in an apparent effort to avoid escalation of the Middle East conflict.
In a post on social media on Thursday, Trump said he was “pausing the period of Energy Plant destruction” until April 6.
In the event of such an attack, Iran has said it would carry out strikes against energy infrastructure in neighboring countries, according to Iran’s Fars News Agency state media.
Wall Street appeared to find little solace in the reprieve from large-scale tit-for-tat attacks on infrastructure.
Iran continues to blockade the Strait of Hormuz, a critical waterway for oil delivery. The strait facilitates the transport of about one-fifth of the global supply of crude oil and natural gas.
Global oil prices stood at about $113 a barrel on Friday, marking a staggering 61% rise since war with Iran began a month ago.
Fatih Birol, the executive director of the International Energy Agency (IEA), earlier this week said the current oil crisis had surpassed the combined effect of worldwide energy shocks in the 1970s.
The global economy faces a “major, major threat,” Birol said at an event in Canberra, Australia, noting that no country would be “immune to the effects of this crisis if it continues to go in this direction.”
U.S. Treasury yields climbed on Thursday, suggesting concern about economic instability and inflation stemming from the Iran war.
The yield on a 10-year Treasury bond, or the amount paid to a bondholder annually, stands at about 4.45%, marking a nearly half-percentage point jump from a month earlier.
On Friday, bond yields soared close to levels reached in the aftermath of President Donald Trump’s “Liberation Day” tariffs last April, when the 10-year Treasury yield peaked at around 4.5%.
Since bonds pay a given investor a fixed amount each year, the specter of inflation risks higher prices that would eat away at those annual payouts.

(NEW YORK) — A threat of U.S. attacks on power plants in Iran continues to loom over the Middle East conflict, even after Trump pushed back a self-imposed deadline for the second time.
In a post on social media on Thursday, Trump said he was “pausing the period of Energy Plant destruction” until April 6.
In the event of such an attack, Iran has said it would carry out tit-for-tat strikes against energy infrastructure in neighboring countries, according to Iran’s Fars News Agency state media.
The threatened escalation risks a humanitarian crisis for tens of millions of people in the region, potentially restricting their access to basic essentials such as electricity, food, water and health care, some analysts told ABC News.
Distress could spread to countries beyond the Gulf if dire conditions prompt residents to flee across borders and infrastructure damage worsens a global oil shock, analysts said.
“This will be bad for everybody,” Mushfiq Mobarak, a professor of economics at Yale University, told ABC News. “The most damaging effects — the largest welfare costs — will be on Iranian civilians.”
On March 21, Trump vowed to “obliterate” power plants in Iran within 48 hours unless the country eases its blockade of the Strait of Hormuz. Before the deadline arrived on Monday night in Washington, D.C., Trump posted on social media that he was postponing the ultimatum for five days, claiming “productive conversations” had been held between the U.S. and Iran.
On Thursday — one day before the new deadline was set to arrive — Trump said he would postpone the deadline for an additional 10 days.
Negotiations between the U.S. and Iran are “ongoing,” Trump claimed. Iranian officials have denied that the country is in talks with the U.S.
Meanwhile, Iran has pledged to retaliate against civilian infrastructure in nearby countries in response to an attack on its energy sites.
“Immediately after the power plants and infrastructure in our country are targeted, the critical infrastructure, energy infrastructure, and oil facilities throughout the region will be considered legitimate targets,” Iranian parliament speaker Mohammad Bagher Qalibaf said in a post on X on Sunday.
Natural gas supplies roughly 79% of electricity used in Iran, according to the International Energy Administration, a global energy policy group based in Paris, France.
The majority of the nation’s natural gas is supplied by South Pars, the largest natural gas field in the world. An Israeli attack on South Pars last week threatened severe impact in Iran and neighboring Gulf states, analysts previously told ABC News.
Potential U.S. attacks on energy infrastructure could cut off electricity access for many of the 92 million people in Iran, while at the same time discontinuing power for critical institutions like hospitals, Mobarak said.
“If hospitals lose power, that’s very dangerous,” Mobarak said.
The health care impact would come as some hospitals in the region face perilous conditions, according to the World Health Organization (WHO). Health care facilities faced a total of 13 attacks as of March 5, the WHO said, voicing concern about “health systems and lives at risk in the region.”
Attacks on civilian infrastructure in Iran could also worsen food shortages and price increases, Michael Werz, a senior fellow at the Council on Foreign Relations, told ABC News. Annual food inflation in Iran stood at 72% in December, before the war began, The Wall Street Journal reported.
Any further deterioration of food access, Werz said, could have a “massive impact.”
Potential Iranian retaliation against civilian sites threatens desperate conditions for millions of people in nearby countries Oman, Qatar, Kuwait, Saudi Arabia, the United Arab Emirates (UAE), Iraq and Israel, some analysts said.
Those countries depend in large part on water desalination plants for drinking water due to arid conditions in the region, making those facilities a major potential vulnerability, Ginger Matchett, assistant director with the GeoStrategy Initiative at the Atlantic Council’s Scowcroft Center for Strategy and Security, said in a blog post.
Desalinated drinking water accounts for at least 90% of the supply in Kuwait, Bahrain and Qatar, while Israel and Oman each depend on such plants for 80% of their drinking water, Matchett said.
“If Iran successfully destroyed the Gulf’s desalination infrastructure, then the consequences could be devastating,” Matchett added.
In early March, desalination plants in Iran and Bahrain were targeted in the fighting, and missile-related damage has also been reported at sites in Kuwait and the UAE.
Potential retaliatory attacks on oil and gas sites in the region also threaten to deepen and prolong a global oil crisis, driving up fuel costs and raising prices for essential goods worldwide, some analysts said.
Global oil prices skyrocketed in recent weeks after the war prompted closure of the Strait of Hormuz, a critical waterway for global oil and natural gas delivery. Consumers have held out hope for a reopening of the strait and a relatively speedy recovery, but facility repairs could stretch on for months and choke off fuel supply in the meantime.
Qatari authorities said last week that Iranian ballistic missile attacks caused fires and “extensive damage” at the Ras Laffan terminal, which carries about one-fifth of the global supply of liquid natural gas. An Iranian missile attack struck oil refineries last week in Haifa, Israel, where fire brigades extinguished a fire that broke out at the site, Israel Fire and Rescue said.
The Philippines has declared a national energy emergency in response to the U.S.-Israeli war with Iran, while South Korea has called on residents to ride bicycles for short trips and reduce the length of showers. Thailand and Vietnam have also asked citizens to take steps to curtail energy use.
Roughly 80% of the oil that typically passes through the strait is bound for Asian markets, according to the IEA. Still, the oil shock will raise gas prices worldwide, since energy is sold on a global market, Mobarak said.
“This will have effects for gas consumers across the world,” he added.

(NEW YORK) — The Dow Jones Industrial average closed up more than 600 points on Monday after President Donald Trump claimed “productive conversations” had been held between the United States and Iran.
The major stock indexes each soared more than 2% in early trading but gave up some of those gains as a flurry of headlines about the U.S.-Israeli war with Iran elicited price fluctuations.
The peace talks — which Iranian officials denied — sent the price of oil plunging on Monday on hopes that negotiations could reopen the Strait of Hormuz and end a weeks-long global energy shock.
The Dow closed up 631 points or 1.3%, while the S&P 500 jumped 1.1%. The tech-heavy Nasdaq increased 1.3%.
Each of the indexes remained below where it stood before the U.S.-Israeli war with Iran began on Feb. 28.
A selloff cascaded across global markets in recent weeks as stockholders feared economic fallout from a potentially prolonged bout of elevated oil prices.
Global oil prices plunged more than 10% on Monday after Trump made his claim about ongoing negotiations with Iran. Still, the price of oil stood above $100 a barrel, marking a steep rise since the outbreak of war.
Trump, after postponing U.S. strikes on Iran’s energy infrastructure citing new negotiations with Tehran, said on Monday that talks will continue and that there are “major points of agreement.”
According to Iranian state media, Iran’s Parliament Speaker Mohammad Qalibaf said, “no talks with the U.S. have taken place; reports claiming otherwise are fake news aimed at influencing financial and oil markets and distracting from the challenges facing the U.S. and Israel.”
