Why gas prices, airline tickets are rising
With the Iran war in its fifth week, consumers are getting hit hard by surging energy costs. Now, some lawmakers are warning of the potential for price gouging, even as experts point to extreme supply shocks.
Traffic through the Strait of Hormuz, a critical maritime shipping route for global oil supplies, remains effectively at a standstill, causing the biggest oil supply disruption in history.
Oil prices have soared more than 40% since the start of the U.S.-Iran war on Feb. 28, triggering price spikes for gas and jet fuel.
Brent crude, the global benchmark for oil, topped $112 a barrel on Friday before retreating. As of Tuesday morning, it was trading at about $103. Gasoline, which is refined from crude oil, reached a nationwide average of $3.98 a gallon as of Tuesday, up about 35% from a month ago, according to AAA.
Jet fuel prices are up about 106% versus a month ago, according to the International Air Transport Association, which measured data for the week ended March 20. Already, some airlines said they will increase fares or tack on fuel surcharges to tickets.
Elizabeth Warren targets price gouging
Sen. Elizabeth Warren, D-Mass., is now urging the Federal Trade Commission to watch for businesses trying to take advantage of consumers by raising prices more than necessary amid the conflict.
“We write regarding our concerns that big corporations may seek to profit off President Trump’s war against Iran by unfairly raising prices for American consumers,” Warren and several other lawmakers wrote in a letter sent Tuesday to Andrew Ferguson, chair of the FTC, and shared exclusively with CNBC.
In the letter, also signed by Sen. Richard Blumenthal, D-Conn., Sen. Ed Markey, D-Mass., Rep. Jan Schakowsky, D-Ill., and Rep. Chris Deluzio, D-Pa., the lawmakers said, “corporations may capitalize on this uncertainty to hike prices more than is warranted by actual input cost increases, price gouging everyday Americans.”
Price gouging occurs when sellers expand their profit margins by raising prices more than necessary to cover higher input costs, they said.

In 2025, Warren introduced the Price Gouging Prevention Act to give the FTC additional authority to litigate alleged abuses. The legislation has been with the Senate Committee on Commerce, Science and Transportation since mid-July. A similar bill co-sponsored by Warren in 2024 failed to pass.
Amid the Iran war, price-gouging concerns are particularly acute for oil, gasoline and fertilizer, the lawmakers wrote; however, “rising input costs could also lead to downstream price increases in other industries, including the food and airline industries,” the letter said.

It takes about five to six weeks for crude oil to be processed and turned into gasoline for delivery, according to Amy Myers Jaffe, director of the Energy, Climate Justice and Sustainability Lab at New York University. “That means that gasoline moving out of refineries based on higher-priced crude oil they received after the war started is only now starting to be shipped to gasoline stations.”
However, some wholesale dealers might be buying gas on the spot market and, in that case, the price spike “would be instantaneous,” Jaffe said.
Because of these market conditions, “there is no price gouging that I can see,” according to Ken Medlock, senior director at the Center for Energy Studies at Rice University’s Baker Institute.
“In fact, the changes in prices at the pump are consistent with historical norms, given the rapid change in crude oil price,” he said.
“The issue is that this is the largest nominal price increase we have ever seen in such a short period of time,” Medlock added.
Jet fuel prices drive airfares up

It’s unclear to what extent price gouging could be a factor in airfares, experts said.
Jet fuel prices are a major input cost for airlines, accounting for about 25% of airlines’ total operating costs, excluding labor, according to an analysis of federal data by Jason Miller, a professor of supply chain management at Michigan State University.
“The reality is, jet fuel prices have more than doubled in the last three weeks,” United Airlines CEO Scott Kirby wrote in a March 20 note. “If prices stayed at this level, it would mean an extra $11 [billion] in annual expense just for jet fuel.”
Higher operational costs will ultimately feed through to higher airfares, Helen McDermott, director of global forecasting at Tourism Economics, wrote in a March 19 research note.
However, price impacts will vary by airline, she wrote. Low-cost carriers tend to see more impact, as jet fuel costs are a higher share of total costs, she wrote.
David Goodger, a managing director and head of tourism forecasting at Tourism Economics, told CNBC he expects airfares to rise “more than would otherwise be the case” due to the war in Iran.
“While the outlook remains uncertain, we expect air fares will be 5-10% higher than we previously expected over 2026 and 2027,” Goodger wrote in an e-mail.
Airlines may impose additional fuel surcharge fees amid prolonged spikes in fuel costs, Goodger said.
“Airlines love to say fuel is expensive so you have to pay more. What they’re doing is they’re setting the expectation,” Courtney Miller, founder of Visual Approach Analytics, an airline industry advisory firm, previously told CNBC. “They price to prevent empty seats.”

Ultimately, there are “too many unknowns” surrounding the Iran war and impact on energy markets, for example, to predict airfare impacts with much certainty, according to Katy Nastro, a spokesperson at Going, a flight deal provider.
There may also be an element of panic-buying among consumers, further exacerbating price increases, said Nastro.
Average airfare for travel between April 20 and May 17 — the period after spring break but before summer — has increased about 10% to 15% at the median, relative to prices just before the war started, Nastro said.
Fares for summer travel are up even more — about 18% — versus a year ago, she said.
“We’re taking the temperature check, and it’s not looking good” for airline prices, Nastro said. “The temperature is rising.”
The affordability issue
The Federal Reserve held interest rates steady at the conclusion of its policy meeting on Wednesday.
In what could be Jerome Powell’s last as chair before President Donald Trump’s yet-to-be-confirmed nominee Kevin Warsh takes the helm, central bankers maintained the federal funds rate in a target range of 3.5% to 3.75%.
Inflation has surged since the war with Iran began, leaving policymakers with limited room to act, according to Sean Snaith, the director of the University of Central Florida’s Institute for Economic Forecasting. “We’re in a kind of suspended animation — between Iran and the Fed transition,” Snaith said.
Before the oil shock, inflation was holding above the Fed’s 2% target but not worsening. Now the jump in energy costs could have longer-term inflationary effects, economists say.
For Americans struggling in the face of higher gas prices and overall affordability challenges, the central bank’s decision to keep interest rates unchanged does little to ease budgetary pressures. “The cavalry isn’t coming anytime soon,” Snaith said.
How the Fed decision impacts you
The Fed’s benchmark sets what banks charge each other for overnight lending, but also has a trickle-down effect on many consumer borrowing and savings rates.
Short-term rates are more closely pegged to the prime rate, which is typically 3 percentage points above the federal funds rate. Longer-term rates, such as home loans, are more influenced by inflation and other economic factors.
Credit cards
Most credit cards have a short-term rate, so they track the Fed’s benchmark.
After the Fed cut rates three times in the second half of 2025, the average annual percentage rate has stayed just under 20%, according to Bankrate.
“Without Fed rate cuts, there’s not much reason to expect meaningful declines anytime soon, so carrying a balance will remain very expensive,” said Matt Schulz, chief credit analyst at LendingTree.
Mortgage rates
Fixed mortgage rates, on the other hand, don’t directly track the Fed but typically follow the lead of long-term Treasury rates.
Concerns about how the Iran war will impact the U.S. economy have already pushed the average rate for a 30-year, fixed-rate mortgage up to 6.38% as of Tuesday, from 5.99% at the end of February, according to Mortgage News Daily.
That leaves homeowners with existing low mortgage rates “feeling stuck,” said Michele Raneri, vice president and head of U.S. research and consulting at TransUnion. “Mortgages, more than any other credit type, work on a churn,” she said, referring to how a dip in rates can boost borrowing activity.
Student loans
Federal student loan rates are also fixed and based in part on the 10-year Treasury note, so most borrowers are somewhat shielded from Fed moves and recent economic uncertainty.
Current interest rates on undergraduate federal student loans made through June 30 are 6.39%, according to the U.S. Department of Education. Interest rates for the upcoming school year will be based in part on the May auction of the 10-year note.
Car loans
Auto loan rates are tied to several factors, including the Fed’s benchmark. Because financing costs remain elevated, new car buyers are taking on longer loans to keep their monthly payments manageable, according to the latest data from Edmunds.
Even so, with the rate on a five-year new car loan near 7%, the average monthly payment on a new car rose to $773 in the first quarter of 2026, an all-time high.
“Car buyers are in a tough spot right now because they’re getting squeezed from both ends: high sticker prices and high interest rates, with neither showing any signs of letting up,” said Joseph Yoon, consumer insights analyst at Edmunds.
“Until the rate picture shifts, buyers will keep stretching loan terms to make payments work, which only adds to the total cost of ownership down the road,” Yoon said.
Savings rates
While the Fed has no direct influence on deposit rates, the yields tend to be correlated with changes in the target federal funds rate. So, although rates on certificates of deposit and high-yield savings accounts have fallen from recent highs, they are holding above the annual rate of inflation.
For now, top-yielding online savings accounts and one-year CD rates pay around 4%, according to Bankrate.
“Yields on high-yield savings accounts and certificates of deposit are down from their peaks of a few years ago, but they’re still strong compared to what we’ve seen for most of the past decade,” Schulz said.

The average tax refund is 11.2% higher this season, compared with about the same period in 2025, according to the latest IRS filing data.
As of April 10, the average refund amount for individual filers was $3,397, up from $3,055 about one year ago, the IRS reported on Friday.
The IRS data reflects about 114 million individual returns received, out of about 164 million expected through Tax Day. Next week’s filing update is expected to include data through the April 15 deadline.
President Donald Trump‘s 2025 legislation, rebranded to the “working families tax cuts,” was a key talking point for Republicans on Tax Day.
With the November midterm elections approaching and Republicans defending slim majorities in Congress, many GOP lawmakers have highlighted Trump’s tax breaks and higher average refunds.
Meanwhile, affordability has been top of mind for many Americans amid rising costs of gas, electricity, food and other living expenses.
For filers who expected a refund this season, nearly one-quarter, or 23%, planned to use the funds to pay down credit card debt, and the same share said they would save the payment, according to the CNBC and SurveyMonkey Quarterly Money Survey, released in April. It polled 3,494 U.S. adults at the end of March.
Who benefited from Trump’s ‘big beautiful bill’
“It’s been a great tax season for the American people,” many of whom have benefited from Trump’s tax breaks, Treasury Secretary Scott Bessent said during a White House press briefing on Wednesday.
More than 53 million filers claimed at least one of Trump’s “signature new tax cuts” — the deductions for tip income, overtime earnings, seniors and auto loan interest — the Department of the Treasury also announced on Wednesday.
Those filers, who claimed the deductions on Schedule 1-A, have seen an average tax cut of over $800, according to the Treasury. Tax cuts can trigger a higher refund or reduce taxes owed, depending on the filer’s situation.
Some filers who itemize tax breaks have also seen benefits from the bigger federal deduction limit for state and local taxes, known as SALT. Trump’s legislation raised that cap to $40,000, up from $10,000, for 2025.
The latest SALT deduction limit change is expected to primarily benefit higher earners, according to a May 2025 analysis of various proposals from the Tax Foundation.
The Treasury has not released data on how many filers have claimed the SALT deduction during the 2026 filing season.

U.S. stocks climbed to record highs on Thursday against a backdrop of war, an oil supply shock and economic forecasts warning of stunted growth amid a protracted conflict.
Many investors may be thinking: Why?
Largely, it’s because the stock market is a barometer of what investors think will happen in the future, rather than an assessment of the present day, according to economists and market analysts.
Investors are essentially shrugging off the Middle East conflict as a blip that will be resolved relatively quickly, they said.
“The stock market isn’t trying to price what’s happening today,” said Joe Seydl, a senior markets economist at J.P. Morgan Private Bank. “The stock market is always trying to price what the world is going to look like six to 12 months from now.”
Why stocks have been ‘resilient’
The S&P 500, a U.S. stock index, fell about 8% in the initial weeks of the Iran war, from the start of the conflict on Feb. 28 to a recent low on March 30.
But stocks have rebounded since then, erasing all losses since the beginning of the war. The S&P 500 closed at an all-time high on Thursday — about 11% higher than its nadir at the end of March. That followed a record close on Wednesday.
“The market has remained very resilient in the face of the war and has rallied strongly on the prospect that it will be resolved,” said Mark Zandi, chief economist at Moody’s.

And while investors cheered the possibility of a diplomatic off-ramp to the conflict, the temporary ceasefire has appeared tenuous, with the U.S. and Iran each accusing the other of breaking the agreement.
Nations haven’t been able to reach a peace deal ahead of the ceasefire’s end. Vice President JD Vance said U.S. officials left peace talks in Pakistan over the weekend after the Iranian delegation refused to agree to American demands not to develop a nuclear weapon.
The markets ‘have memory’
Ultimately, the stock market is signaling a collective belief that tensions will ratchet down, the war will end in the near term and oil flows through the Strait of Hormuz will normalize, economists said.
That’s largely because investors have been conditioned to believe that President Donald Trump will back off if the economic pain becomes too intense, economists said — the so-called “TACO” trade, shorthand for “Trump always chickens out.”
“Investors strongly believe — and have been conditioned to believe — he’s going to stand down, find a way to pivot, declare victory and move on,” Zandi said.
Trump has pushed back on the notion of backing down, framing his brinkmanship as a savvy negotiating tactic.
Economists pointed to a recent example of this dynamic: in April 2025 during so-called liberation day, when the Trump administration levied a host of tariffs on U.S. trading partners.
Within days — after the stock market had cratered more than 12% — Trump announced a 90-day pause on those tariffs. Stocks then saw one of their biggest daily rallies in history following Trump’s reversal.
Investors remember that Trump often de-escalates geopolitical shocks — which is why they’ve seized on positive headlines that hint at progress in peace talks, for example, Seydl said.
“The markets have memory,” Seydl said.
AI stocks and the ‘tech boom’

There are other factors underpinning market resilience during wartime, economists said.
One is the investors’ enthusiasm for artificial intelligence and technology stocks, which account for almost half of the S&P 500’s market capitalization, Zandi said.
“Those stocks run on their own dynamic independent of anything, including the war in Iran,” Zandi said. “I think we would have been down a lot more and it would have been harder for us to recover had it not been for the very, very optimistic perspectives on AI.”
We’re in the middle of a “tech boom” — and investors are likely to remain optimistic until they think the tech cycle has run its course, Seydl said.
More broadly, stock investors are essentially making a bet on the future earnings growth of a company — and the earnings backdrop has been “pretty solid,” Seydl said.
Consumer spending appears to be stable, for example, economists said. And companies are getting a boost to their after-tax earnings from the GOP’s so-called “big beautiful bill,” which, among other things, made it easier to write off investments upfront and therefore reduce their tax liability, Zandi said.
Going forward
Experts said there will be an economic hit from the Iran war, though.
“Despite the recent news of a temporary ceasefire, some damage is already done, and the downside risks remain elevated,” Pierre-Olivier Gourinchas, director of research at the International Monetary Fund, wrote Tuesday.
A protracted conflict risks deep and global economic pain, he wrote.
Even if the conflict is short-lived — as the broad market expects — stocks are unlikely to march much higher until it’s clear the U.S. is on the other side of the war and its economic fallout, Zandi said.
If investors are incorrect, and President Trump doesn’t back down or quickly extricate the U.S. from the war, the stock market may see a “full-blown correction” or worse, Zandi said. A stock market correction is a decline of at least 10% from recent highs.
“Everyone thinks they know what the script is,” Zandi said. “Now they just need to follow the script. If they don’t, the market will have some real problems.”
The uncertainty provides yet another example of why the average investor with a long time horizon should stick to their investment plan and ignore the noise, experts said.
“Trying to time the market is very difficult if not impossible for the average investor,” Seydl said. “It’s better to take a long-term perspective and ride out bouts of volatility.”
