Iran War, Tariffs Raise New Risks for a Resilient U.S. Economy
**Slower growth could cast a pall on the November midterm elections as gas prices top $4 a gallon and a new wave of tariffs adds to the cost of everything from wine to washing machines.**

## The Summer That Wasn't
A few short weeks ago, the U.S. economy seemed to be catching a break. The war with Iran appeared to be waning. Energy markets had started to calm. Gas prices had fallen below $4 a gallon, and inflation had begun to cool. It looked like Americans might finally get some relief just in time for the summer driving season and the midterm elections .
Then the reprieve collapsed.
President Trump resumed major U.S. military attacks against Iran after it struck oil tankers in the Persian Gulf, sending gas prices surging above $4 a gallon again and threatening to reignite inflation . At the same time, the White House formalized a slate of new tariffs on dozens of countries, including the European Union, Canada, and Mexico . The duties apply to some of the largest U.S. trade partners, reigniting fears of a broader trade war .
The forces, taken together, have complicated the nation's economic outlook in familiar ways. Once, economists figured that an end to the hostilities in the Middle East would spell a gradual return to normal. Instead, the renewed fighting cast those assumptions into doubt, leaving the nation's long, hard fight against inflation as vexing as ever .
## The Oil Shock: $100 a Barrel and $4 Gas
The most immediate pain for American families is at the pump. The average national price for regular gasoline hit $4.11 on July 25, up from just over $3 a year ago . In some parts of the country, prices are even higher. The surge has been driven by the renewed fighting in the Strait of Hormuz, a critical chokepoint through which roughly one-fifth of the world's oil passes .
**Brent crude oil, the global benchmark, surged above $100 a barrel** — its highest level since June 2026 . The uncertainty has made projections extremely difficult. GasBuddy's head of petroleum analysis said it's "akin to hitting a dartboard through the woods 5,000 miles away" .
The ripple effects are already spreading. Higher energy costs affect everything from shipping to fertilizer to manufacturing. Economists warn that if oil stays at $100 a barrel, the average household with oil heat could see winter heating bills rise to $1,700, compared with roughly $1,100 last winter .
**Some Republicans are getting worried**. "We should all be concerned any time you're seeing basic commodity prices going up," said Senator Mike Rounds, a South Dakota Republican facing reelection this fall .
## The Tariff Wall: A New, More Durable Regime
Just as the war was driving up energy costs, the administration finalized a new set of tariffs that took effect on July 24 . The duties range from 10% to 12.5% on imports from more than 60 trading partners, including Canada, Mexico, the European Union, Japan, South Korea, and Switzerland .
**The tariffs are imposed under Section 301 of the Trade Act of 1974**, which targets unfair trade practices, particularly concerns that countries have not cracked down on "forced labor" . The move is seen as a strategy to build a more durable tariff wall after the Supreme Court struck down Trump's broader emergency tariffs earlier this year .
Trade Representative Jamieson Greer defended the tariffs before the Senate Finance Committee: "The specific authorities this administration is using have changed, but the trade strategy has not" .
**But the economic impact is real**. The Yale Budget Lab estimates the new tariffs could raise the average tariff rate on imports to 12.8% by the end of the year, up from 9.8% if the administration had allowed existing tariffs to expire. Households could face an average of $1,100 in additional annual costs under the full slate of Trump's recent policies, compared with about $550 under current law .
## The Economic Crossroads: Resilient but Vulnerable
Despite the headwinds, the U.S. economy has shown remarkable resilience. Analysts at Oxford Economics estimated the economy could grow 2.3% this year . The labor market remains strong, with jobless claims falling to their lowest level since 1969 .
**But inflation remains a scourge**. Consumer prices were still 3.5% higher in June than a year earlier—well above the Federal Reserve's 2% target . The renewed fighting in the Middle East risks undoing the progress made in recent months. A Dallas Fed analysis found that the inflationary effects of the Strait of Hormuz closure "completely undo the disinflationary effects" of the recent tariff reductions .
For lower-income Americans, who devote a larger share of their monthly income to energy costs, the impact is particularly severe .
## The Midterm Stakes
The economic headwinds loom especially large over Trump, with less than four months until the midterm elections . **Polling shows the economy is front and center for voters**. A Pew Research Center survey found that 29% of registered voters cite economic issues as the most important topic they want candidates to discuss—more than any other issue .
The poll also shows that neither party holds a clear advantage on economic policy: 37% of Americans say they agree with the Democratic Party, while 36% say they agree with the Republican Party . Democrats hold a modest edge on the generic ballot, with 43% saying they would back a Democratic candidate versus 37% for Republicans .
**The war is also taking a toll on Trump's support**. A Politico poll found that only 37% of self-identified MAGA Trump voters say the Iran war is worth the economic cost, down from 50% in early May . Overall, 63% of adults blame the war for the high gas prices .
Some Republicans are already bracing for the political fallout. "Eventually, I think people's pocketbooks are going to impose reality on them," said Representative Thomas Massie, a Kentucky Republican. "We're already seeing that with farmers, and that's why you've got this $12 billion bailout... Here's $12 billion. Please don't punish us in the midterms" .

## A Long, Hard Fight
The resurgence of the Iran war, combined with a new wave of tariffs, has thrown the U.S. economic outlook back into uncertainty. The "summer break" that Americans had hoped for has given way to a familiar pattern of rising prices, geopolitical tension, and political anxiety.
