As petrol prices rise, new survey suggests economic confidence in the US is at -45, the worst since 2022.

Only 16 percent of Americans view the economy in the United States as “good” or “excellent”, a new Gallup poll suggests, as inflation continues to rise amid the war on Iran.

The survey, released on Friday, deepens US President Donald Trump’s political woes ahead of the midterm elections in November, which will determine whether his Republican Party can retain control of Congress.

The survey, dubbed Gallup’s Economic Confidence Index, showed confidence in the economy has dropped to -45.

Forty-nine percent of respondents said economic conditions are poor and 34 percent rated them as fair. At the same time, 76 percent said they think the economy getting worse, while 20 percent said it is getting better.

The index averages the results on economic conditions, currently at -33 and economic outlook, currently at -56.

It was the worst set of findings on the economy that the index recorded since 2022 when the cost of living rose after the COVID-19 pandemic and Russia’s invasion of Ukraine.

Petrol costs in the US have skyrocketed since the start of the conflict with Iran late in February. The average price of one gallon (3.8 litres) of gasoline has risen to $4.55 from less than $3 before the US and Israel launched the war.

According to official government reports, consumer prices overall rose in March and April due to the energy crisis.

Iran has responded to the US and Israeli strikes – which killed several top officials, including Supreme Leader Ali Khamenei, as well as hundreds of civilians – by closing the strategic Strait of Hormuz, sending oil and gas prices soaring.

The US has also imposed a naval siege on Iranian ports, deepening the strain on energy supplies across the world.

Despite the ceasefire that began in April, the blockades have persisted in the absence of a permanent end to the war, and Iran is now claiming sovereignty over Hormuz, which operated as a free international passageway before the war.

Parts of the strait run through Iranian and Omani territorial waters.

Although the US is one of the world’s largest oil producers, energy prices are set globally, so the disruption has spiked costs for American consumers.

As a candidate, Trump promised to be a president of “peace”, saying he would pursue “America first” policies that would prioritise domestic issues over foreign interventions.

But the US president joined Israel in attacking Iran without direct provocation. His administration argues that the military campaign is necessary to prevent Tehran from obtaining a nuclear weapon.

Iran denies seeking nuclear weapons. And Trump’s own intelligence chief Tulsi Gabbard has said that Tehran is not building a nuclear bomb.

Trump has repeatedly argued that the cost of the war is worth it, stressing that petrol prices will drop rapidly once the conflict is over.

Last month, the US State Department released a legal justification of the war, saying that Washington joined the conflict “at the request of and in the collective self-defence of its Israeli ally, as well as in the exercise of the United States’ own inherent right of self-defence”.

The Gallup survey on Friday is the latest in a series of negative polls for the Trump administration.

A New York Times/Sienna poll released earlier this week suggested that only 31 percent of voters approve of Trump’s handling of the war with Iran.

Earlier this month, the US president suggested the economic fallout from the war and its effect on people in the US do not play a role in his approach to Iran.

“I don’t think about Americans’ financial situation. I don’t think about anybody,” he said. “I think about one thing: We cannot let Iran have a nuclear weapon. That’s all. That’s the only thing that motivates me.”
