Energy Secretary Chris Wright said oil and gas prices will begin to fall when the U.S. begins to knock out Iran’s ability to hinder tanker traffic through the Strait of Hormuz, as Americans weather spiking gas prices due to the war in Iran.

“The plan is to get oil and natural gas and fertilizer and all the products from the Gulf flowing through the straits before too long,” Wright said on Fox News Sunday. “We’re massively attriting their ability to strike with missiles and drones, and that rate of attrition will increase in the coming days. So we’ll be cautious, we’ll be careful, but energy will flow soon.”

President Donald Trump was elected to a second term in the White House in part by promising to lower gas prices and defeat high inflation. He has frequently touted lower gas prices ahead of the November midterm elections, which will determine control of Congress for the remainder of his term.

But gas prices and oil have spiked since the war began in Iran, with vessel bottlenecks in the Strait of Hormuz causing the surge. About 20% of global energy supply moves through the strait.

Gas has jumped to over $3.46 per gallon on average in the U.S., according to GasBuddy. U.S. crude oil has soared to more than $91 per barrel, and the global benchmark Brent crude has spiked to over $92 per barrel.

Wright said that “one large tanker has already gone through the straits with no issues at all.” Typically, roughly 100 tankers and cargo ships move through the strait every day.

Wright said the disruption would last for “weeks, certainly not months.”

“We believe this is a small price to pay to get to a world where energy prices will return back to where they were,” Wright said. “Iran will finally be defanged, and now you can see more investment, more free flow of trade, less ability to threaten energy supplies.”

When asked about potentially tapping the U.S. Strategic Petroleum Reserve to reduce pain at the pump, Wright suggested such a move is not necessary yet. In the past, the SPR has been tapped to mitigate disruptions in oil flows.

“We’re more than happy to use [the SPR] if needed,” Wright said on CBS’s “Face the Nation.” “But … it’s a logistics issue, where do they need oil? They need oil at refineries in Europe and in Asia.”

Trump has also downplayed the option of tapping the SPR.

“We’ve got a lot of oil. Our country has a tremendous amount,” Trump told reporters aboard Air Force One on Saturday. “There’s a lot of oil out there. That’ll get healed very quickly.”

November’s midterm was always supposed to be about affordability. Then, the bombs began falling in Iran.

The expanding U.S. war in the Middle East threatens to scramble the cost-of-living narrative that has so far defined the contest for control of Congress. The election, now less than eight months away, will determine whether President Donald Trump retains his iron grip on Washington or spends his last two years in office fending off Democratic congressional majorities.

Both parties have sought to capitalize on kitchen-table issues, as Americans struggle to keep up with the rising costs of ordinary goods and services. The war in Iran now threatens to exacerbate those concerns — and Democrats are seizing on the opportunity to pillory Trump and Republicans for beginning a conflict that could make life even more expensive for ordinary Americans.

“Because there was no plan going in, I think there will be lots of things that are unforeseen consequences of this,” Sen. Martin Heinrich, D-N.M, the top Democrat on the Senate Energy and Natural Resources Committee, said in an interview with CNBC. “I mean you saw how much gas has gone up in a day, oil futures have gone up, there are going to be a lot of knock-on effects.”

Some of those knock-on effects have already been evident. U.S. crude oil has jumped past $90 per barrel, up from $67 the day before the war broke out. The global market index Brent has skyrocketed to more than $90 per barrel. That’s caused gas prices to spike to about $3.38 per gallon, according to a national average from Gasbuddy, up more than 35 cents from the week before the war.

Rep. Jared Huffman, D-Calif., the ranking member of the House Natural Resources Committee, was quick to point out in an interview that liquefied natural gas prices have also spiked. Though U.S. increases have been modest so far, global LNG supply has been squeezed by a shutdown in Qatar — one of the world’s top LNG-producing countries. Natural gas is the largest electricity generator in the U.S., which is critical as the booming data center industry stresses the electric grid and increases utility costs.

“I think what American families have been feeling most acutely for the past year-plus is their energy bills, their utility bills rising,” Huffman said. “A big part of the utility bill increase is that natural gas is getting more and more expensive … a lot of our effort has been pushed into LNG exports instead of strategies that would lower bills for American consumers. That problem is only more amplified by this conflict.”

But a quick operation in Iran is far from certain, and any extended conflict could create an election-year quagmire for Republicans, said Brittany Martinez, executive director at Principles First and a former aide to then-House Speaker Kevin McCarthy, R-Calif.

“If energy prices rise or markets stay volatile, affordability becomes a harder message for Republicans to carry cleanly,” Martinez said. “Republicans will argue that projecting strength abroad prevents greater instability, while Democrats will try to link any sustained price increases to foreign policy decisions. The real question is whether this turns into a prolonged conflict that voters feel in their household budgets.”

Many believe the military intervention in Iran has the potential to drag on, including Sen. Andy Kim, D-N.J., a national security advisor in the Obama White House.

“This administration doesn’t seem to think about this at all,” Kim said when asked about a potential power vacuum keeping the U.S. in the region longer. “The intelligence community has done a whole range of assessments that very much keep me up at night, and the fact that this White House, I assume, read the same things I read and still went through with this, I just find that to be absolutely reckless.”

Complicating matters more for the GOP is that the war in Iran is unpopular. A CNN poll released March 2 found that nearly 60% of those surveyed disapproved of the U.S. taking military action in Iran. That comes as Trump’s economic approval remains underwater: A Fox News poll released March 4 found that 61% of voters disapproved of Trump’s job on the economy.

“We don’t see it as an opportunity, but I do think it’s our responsibility to tell the American people exactly the decision that Donald Trump is making,” said House Democratic Caucus Chair Pete Aguilar, D-Calif. “He’s sending billions of our tax dollars to the Middle East for another war while he’s kicking people off of healthcare and … eliminating nutrition programs.”

Rep. Zach Nunn, an Iowa Republican seeking reelection in a district Cook Political Report with Amy Walter has labeled a “toss up,” said he is not concerned the war could drown out the GOP’s affordability message. He pointed to the sprawling tax and spending bill that was signed into law last year, increased domestic energy production, and housing legislation that advanced out of the House last month as examples of things the party will use to show action on rising costs.

War in the Middle East does not necessarily preclude Republicans from continuing to try to bring prices down, he argued.

“A more fulsome conversation would be, how do we make sure that we still deliver on affordability?” Nunn said in an interview. “I think this is the absolute right spot for us to be in.”

But Trump, the “America First” president who campaigned on ending the U.S.’s foreign entanglements, risks alienating his base with his Iran offensive. Democrats see the war as evidence of what they have been telling voters about Trump all along: he does not care affordability.

“We have a president who has campaigned on ending forever wars, and he has jumped into war without justification or explanation to the American people,” said Rep. Suzan DelBene, D-Wash., chair of the Democratic Congressional Campaign Committee. “So this has been broken promise after broken promise. This has been at the expense of the needs of everyday Americans. And I do think voters will hold them accountable in November.”

President Donald Trump said in a social media post on Friday that there would be no deal to end the U.S. war against Iran without an “UNCONDITIONAL SURRENDER” by Iran.

The Dow Jones Industrial Average dropped more than 900 points, or nearly 2%, after Trump’s demand, which he wrote on Truth Social. The S&P 500 and Nasdaq Composite fell 1.6% each, and oil futures prices rose.

Trump said that after a surrender and “the selection of a GREAT & ACCEPTABLE Leader(s), we, and many of our wonderful and very brave allies and partners, will work tirelessly to bring Iran back from the brink of destruction, making it economically bigger, better, and stronger than ever before.”

“IRAN WILL HAVE A GREAT FUTURE. “MAKE IRAN GREAT AGAIN (MIGA!)” Trump wrote.

Trump’s demand came as Iran has yet to pick a leader to replace Supreme Leader Ayatollah Ali Khamenei, who was killed last weekend in an airstrike at the beginning of the war by the U.S. and Israel.

White House Press Secretary Karoline Leavitt, when asked by reporters later about potential future leaders of Iran, said, “I know there are a number of people that our intelligence agencies, that the United States government are looking at, but I won’t get any further.”

Trump in June made an identical demand of “UNCONDITIONAL SURRENDER” by Iran in another social media post as he considered launching a military strike against that nation.

The futures price of the global benchmark Brent crude oil rose, breaking $90 per barrel, after Trump posted his latest demand for Iran to surrender without conditions.

Qatar’s energy minister, Saad al-Kaabi, warned Friday that rising oil prices due to the war against Iran “could bring down the economies of the world.”

Al-Kaabi told The Financial Times that crude oil prices could hit as high as $150 per barrel within weeks if tankers cannot pass through the Strait of Hormuz. The last time oil topped $100 a barrel was when Russia invaded Ukraine in 2022.

Oil prices rose on Friday morning as investors continued to assess the impact of the U.S.-Iran war on global energy markets.

By 6:58 a.m. ET, global benchmark Brent crude futures added 4.5% to trade at $89.23 a barrel, notching a fresh 52-week high and levels not seen in nearly two years. U.S. West Texas Intermediate crude futures were last seen 6.3% higher at $86.06, hitting their highest level since April 2024.

Prices dipped overnight as investors continued to assess the impact of the U.S.-Iran war on global energy supply.

Crude prices are on track for their biggest weekly gain since Russia’s full-scale invasion of Ukraine in early 2022.

The spike comes as the U.S.-Iran conflict spreads across the Middle East, disrupting energy production and bringing traffic in the Strait of Hormuz, a critical shipping route, to a near standstill.

On Friday morning, the Financial Times reported that Qatar’s energy minister said the war in the Middle East could see Gulf energy exporters stop shipments within days. Saad al-Kaabi told the FT that crude prices could reach $150 a barrel in the coming weeks if oil tankers were unable to pass through the Strait of Hormuz.

Prices briefly dipped overnight after the U.S. issued a 30-day waiver to India — the world’s third-largest oil importer — to resume purchases of Russian oil. Washington had earlier imposed 25% “penalty” tariffs on India for buying Russian crude, which were revoked last month. The retreat in prices also came after news agency Reuters, citing an unnamed White House official, reported that the U.S. Treasury is planning to announce measures to curb energy price spikes, including potential interventions in the oil futures market.

The average price for a gallon of regular gasoline jumped nearly 27 cents since in the week to Thursday to $3.25, according to data from U.S. travel organization AAA.

The conflict between Iran and the U.S. enters its seventh day on Friday. In a press conference on Thursday, U.S. Defense Secretary Pete Hegseth said the U.S. had “only just begun to fight.”

“Iran is hoping that we cannot sustain this, which is a really bad miscalculation,” he told reporters.

“There’s no shortage of American will here … If you think you’ve seen something, just wait. The amount of combat power that’s still flowing, that’s still coming, that we’ll be able to project over Iran is at multiples of what it currently is right now when you add up our capabilities and those of the Israeli Defense Forces.”

“Contrary to what consensus thinks, I think higher energy prices could actually be deflationary for the U.S.,” Atakan Bakiskan, chief U.S. economist at Berenberg, told CNBC’s “Squawk Box Europe” on Friday.

“Cuba’s next,” said Sen. Lindsey Graham, a Republican and ally of U.S. President Donald Trump, after the U.S. and Israel began strikes on Iran.

The U.S. has imposed an oil blockade on the communist-run island nation since January, shortly after its ally and a key provider of oil, Venezuelan President Nicolás Maduro, was seized in an extraordinary U.S military operation. It has caused a worsening economic crisis and left Cuba facing its biggest test since the collapse of the Soviet Union.

Now Iran, with which Cuba has a strategic partnership, is under sustained attack. “This communist dictatorship in Cuba, their days are numbered,” Graham told Fox News’s “Sunday Night in America.”

Before the Iran strikes, Trump said he wanted a “friendly takeover” of the island, without giving details. The comments, alongside the U.S. attacks on Iran and Venezuela, have done little to allay growing fears in Havana, experts told CNBC.

A “friendly takeover” could resemble Venezuela in the aftermath of Maduro’s removal, “where you still have an authoritarian regime in power but moving in the direction and at the speed that the US determines,” said Carlos Solar, senior research fellow, Latin American Security at RUSI, a London-based defense think tank.

Solar told CNBC by email that Cuba had lost support from Venezuela and Iran “at a moment of maximum pressure” from the Trump administration.

But he added: “What is unclear is how the US will make the Cuban regime break, forcing Havana to capitulate.”

“We are not seeing the kind of military buildup prelude to operation Absolute Resolve that eventually led to Maduro being captured in January. It could well be that the US approaches Cuba in a totally different way,” Solar said.

A spokesperson for the White House and Cuba’s embassy in London did not respond to a CNBC request for comment.

Cuba’s Foreign Affairs Ministry has called for an end to the Middle East conflict and said it “condemns in the strongest terms” the joint U.S. and Israel attack on Iran on Feb. 28.

Russia recently warned that the situation in Cuba appeared to be escalating after Cuban forces killed four people who were off its coast in a U.S.-registered speedboat.

Trump has also said Cuba’s government poses “an unusual and extraordinary threat” and pledged to impose tariffs on any country that supplies it with oil. The U.S. Treasury said late last month, however, that it would allow the resale of Venezuelan oil to Cuba’s private sector.

The move appeared to reflect a small step to alleviate the island’s acute fuel shortage, which has forced a wave of airlines cut flights to the country. Tourism has long been a significant source of revenue for Cuba’s cash-strapped government.

Par Kumaraswami, professor of Latin American Studies at the U.K.’s University of Nottingham, told CNBC the Trump administration’s strikes against Iran and recent comments about Cuba’s regime had increased the mood of uncertainty and anxiety in Havana.

“Cubans are increasingly concerned about how they will survive in the midst of such global chaos, and the recent violence against Iran will have done nothing to allay their fears,” Kumaraswami said by email.

“At the same time, there are indications that the US administration is negotiating with the Cuban government regarding changes to Cuba’s economy, and this is indeed mirrored by Cuban President Miguel Díaz-Canel’s current focus on economic improvement as the priority,” she added.

Kumaraswami said the “message from Cuba” had been “constant” since the communists came to power in 1959: “Survival will only be achieved through adaptation to the changing geopolitical context.”

Cuba has adopted measures to protect essential services and ration fuel supplies for key sectors. The United Nations has previously warned of a possible humanitarian “collapse” as the country’s oil supplies dwindle.

“Cuba just bought itself a window — but it’s a narrow one,” Robert Munks, head of Americas research at risk intelligence company Verisk Maplecroft, told CNBC by email.

“The operation against Iran removes Cuba – temporarily – from Washington’s sights, as the US administration will be preoccupied with the Gulf campaign in the coming weeks.”

But Munks said he expected Cuba to return to the headlines, adding that the Cuban diaspora in South Florida would apply pressure and Washington has shown it is prioritizing the Western Hemisphere in its remodeled national security strategy.

Oil prices have soared after U.S. and Israeli strikes on Iran continued on Sunday night.

Brent crude prices hit a new 52-week high on Monday, surging 9.3% to reach $79.40, while U.S. West Texas Intermediate prices also rose more than 9% to $73.10.

U.S. President Donald Trump said the “overwhelming military offensive” — which he has dubbed Operation Epic Fury — would continue until the U.S.’s objectives are achieved. Israel launched fresh strikes against both Iran and against Hezbollah targets in Lebanon late on Sunday, which came after Iran attacked military and infrastructure targets across several countries in the region.

As the U.S. continues to target Iranian air defense systems and naval capabilities, global oil supplies have come into sharp focus.

Amrita Sen, founder and director of research at Energy Aspects, told CNBC on Monday that she expects oil prices to likely hold at around $80 level for some time.

Sen said that it is unlikely that the Strait of Hormuz — through which 13-15 million barrels, or 20% of global supply, of oil flows — would be closed altogether. She added that the bigger risk stems from one-off attacks on vessels passing through the area.

Sen said that the U.S. and Israel have the superior military power to ultimately neutralize Iran’s ability to completely shut off the Strait, a key shipping channel for oil producers such as Saudi Arabia, the UAE, Iraq, Iran, and Kuwait.

But single attacks on ships are more difficult to prevent. “This is something we’ve warned right throughout to our clients,” she said.

After three tankers were hit over the weekend, shippers are now being extremely cautious about going in, she added.

“That is the biggest issue right now — how do Asian refiners actually get the volumes from the Middle East?” Sen added.

She noted that Oman and certain UAE grids can bypass the Strait, while Saudi Arabia has contingency plans to move its oil through the East-West pipeline via the Red Sea.

“But even if you are able to move 5 million out through other methods, about 10 is still stuck,” she added.

Sen added that, if energy infrastructure is hit, the price of oil could hit $100.

She added that “the stakes are just too high” when it comes to potential attacks on infrastructure.  

The U.S. and Iran are poised to hold further nuclear talks in the Swiss city of Geneva on Thursday, amid persistent fears about the prospect of military action in the oil-rich Middle East.

The upcoming round of negotiations over the future of Tehran’s nuclear program come as the U.S. continues to build up military forces in the region and as President Donald Trump warns of “bad things” if Iran doesn’t agree to a nuclear deal.

The U.S. president on Tuesday spoke briefly about Iran during his nearly two-hour State of the Union address but primarily focused on domestic policy and other political issues.

“We are in negotiations with them. They want to make a deal, but we haven’t heard those secret words: ‘We will never have a nuclear weapon,'” Trump said.

“My preference is to solve this problem through diplomacy. But one thing is certain, I will never allow the world’s number one sponsor of terror, which they are by far, to have a nuclear weapon.”

For some, the comments boosted expectations of an imminent diplomatic breakthrough.

Trump “basically wants the optics of a win, which is why he talks about why he’s ended eight wars. I think it’s pretty clear he hasn’t. He has helped navigate, you know, skirmishes … but he hasn’t ended these conflicts,” said George Pollack, U.S. policy analyst at Signum Global Advisors.

“For him, I think it is more about how he’s exerting U.S. strength, U.S. force and trying to make the world more peaceful but that’s more optics than it is a substantive policy,” Pollack told CNBC’s “Europe Early Edition” on Wednesday.

“And that’s why, for us, we do think this Thursday meeting will likely be a success and bring about some more diplomatic opportunities,” he added.

For others, however, the absence of a deal means the likelihood of military action appears to be both high and growing.

“President Trump’s 10-to-15-day deadline for Iran works out to a date sometime in very early March,” strategists at Dutch bank ING said in a note published Wednesday.

“This uncertainty means the market will continue to price in a large risk premium and remain sensitive to any fresh developments,” they added.

Iranian Foreign Minister Abbas Araghchi said on social media Tuesday that the country would resume talks with the U.S. in Geneva this week “with a determination to achieve a fair and equitable deal — in the shortest possible time.”

Araghchi added: “Our fundamental convictions are crystal clear: Iran will under no circumstances ever develop a nuclear weapon; neither will we Iranians ever forgo our right to harness the dividends of peaceful nuclear technology for our people.”

Oil prices traded near seven-month highs on Wednesday morning as energy market participants continued to closely monitor potential supply disruptions.

International benchmark Brent crude futures with April delivery rose 0.6% to $71.13 a barrel, while U.S. West Texas Intermediate futures with April delivery, traded 0.6% higher at $66.02.

Iran, a member of OPEC, is a major player in the global oil market, producing more than 3 million barrels of crude a day.

The Islamic Republic has recently conducted military drills in the strategically important Strait of Hormuz, as well as joint naval drills with Russia in the Gulf of Oman, also known as the Sea of Oman.
