You've probably noticed: gas prices aren't going down. And if you've been waiting for the relief President Donald Trump promised on the campaign trail, Nobel Prize-winning economist Paul Krugman has some bad news — it's going to get worse before it gets better.

In a recent appearance on MSNBC's Ari Melber show, Krugman didn't mince words about the economic consequences of escalating tensions with Iran. "It's going to be bad," he said, pointing to a ripple effect that extends far beyond what you pay at the pump.

The warning comes as the Trump administration's aggressive posture toward Iran threatens to disrupt oil markets and global supply chains. While Trump has repeatedly touted his ability to bring down energy costs, the current trajectory suggests the opposite outcome — and according to reporting from Alternet, even some of his own economic advisers are expressing doubts about the feasibility of his pricing promises.

The Broader Economic Picture

Krugman's concern isn't just about gasoline. When oil prices spike due to geopolitical instability, the effects cascade through the economy. Transportation costs rise, affecting everything from groceries to electronics. Manufacturing becomes more expensive. Plastics, which derive from petroleum, cost more to produce. The inflation that Americans have only recently seen moderate could roar back to life.

This isn't theoretical hand-wringing. History provides a clear playbook: the 1979 Iran hostage crisis sent oil prices soaring and contributed to stagflation that plagued the U.S. economy for years. The 1990 Gulf War caused similar disruptions. Even temporary conflicts in the Middle East have proven capable of sending shockwaves through global markets.

The timing couldn't be worse for an administration that built much of its economic messaging around the promise of lower prices. Trump frequently criticized his predecessor over inflation and energy costs, pledging to reverse both trends quickly. Instead, his own foreign policy choices may be undermining those goals.

When Campaign Promises Meet Geopolitical Reality

Here's the problem with promising cheap gas while simultaneously ratcheting up military tensions in the world's most critical oil-producing region: the two goals are fundamentally incompatible. Iran sits along the Strait of Hormuz, through which roughly one-fifth of the world's oil supply passes. Any serious conflict there doesn't just affect Iranian oil exports — it threatens the entire regional supply chain.

According to Alternet's reporting, this contradiction hasn't gone unnoticed within the administration itself. When your own economic team starts poking holes in your public claims, that's usually a sign the gap between rhetoric and reality has grown too wide to ignore.

The question isn't whether increased tensions with Iran will affect oil prices — it's how much, and for how long. Energy markets hate uncertainty, and few things create more uncertainty than the prospect of military conflict in the Persian Gulf.

Who Pays the Price?

If Krugman and other economists are right, American consumers will bear the brunt of this policy collision. Middle-class families already stretched by years of elevated inflation would face another round of price increases, this time driven not by pandemic supply chain issues or stimulus spending, but by deliberate foreign policy choices.

The political calculus here is tricky. Trump won support partly by promising economic relief, particularly on everyday costs like gas and groceries. If those prices instead climb due to his Iran policy, the administration will need to explain why the tradeoff was worth it — and whether alternative approaches might have achieved security goals without the economic pain.

This isn't about whether confronting Iran is justified on security grounds. Reasonable people can disagree about the appropriate level of pressure on Tehran. But the economic consequences of that pressure are predictable and significant, and voters deserve an honest accounting of what they're being asked to accept.

The Credibility Gap

What makes this situation particularly awkward for the White House is the source of the skepticism. When outside critics question your economic claims, you can dismiss them as partisan. When your own advisers express doubts — as Alternet reports they have — that's a different problem entirely.

It suggests either a lack of coordination between foreign policy and economic policy teams, or a deliberate decision to prioritize other goals over the cost-of-living promises that helped win the election. Neither explanation will comfort Americans watching prices climb.

Krugman's warning also highlights a broader challenge for any administration: you can't simply will economic outcomes into existence through messaging and promises. Markets respond to fundamentals — supply, demand, risk, and uncertainty. No amount of confident rhetoric changes the fact that conflict in the Middle East disrupts oil supplies and raises prices.

The coming months will test whether the administration can thread this needle — pursuing its Iran policy while somehow insulating Americans from the economic consequences. Based on historical precedent and current expert analysis, that looks like an increasingly difficult proposition.

For now, economists like Krugman are sounding the alarm. Whether policymakers listen, or whether American consumers will simply have to learn this lesson the expensive way, remains to be seen.
