The episode examines how global financial markets are digesting the escalating U.S.-Iran war. Ed Elson hosts a panel with Katie Martin, markets columnist at The Financial Times, and Justin Wolfers, professor of economics and public policy at the University of Michigan. Brent crude spiked to $119 on Monday before falling to $85 by Tuesday, while the Strait of Hormuz remains effectively closed and at least 20 countries are militarily involved.
Katie Martin explains the counterintuitive market reaction: oil rose as expected, but gold, the Swiss franc, the yen, and government bonds all moved opposite to what a classic geopolitical shock would produce. She argues investors were taking profits rather than fleeing to safety, and that the most durable signal is in bond markets, sensitive to the inflationary impact of higher oil prices. Justin Wolfers frames markets as a "sophisticated machine for aggregating news" when traditional sources are broken, and introduces the "competence shock" — the U.S. appears to be run without planning, undermining confidence in America as a safe haven. He cites his Iraq war research: a 10% probability increase in war moved U.S. stocks by 1.5 points, implying the full conflict would wipe 10–15% off the market.
The two guests disagree on whether markets are resilient enough to absorb this shock. Katie argues central banks have proven effective at containing crises and that the "avoid America" trade is diversification, not panic selling. Justin counters that the deeper question is whether Trump's "autocrat project" will destroy the institutional foundations that make economies resilient, comparing the U.S. to Turkey, Hungary, and Argentina.
Counterintuitive Market Reaction to Iran Warinsight
Katie Martin explains that while oil rose as expected, gold, the Swiss franc, the yen, and bonds all moved opposite to what a geopolitical shock would produce. She interprets this as investors taking profits rather than fleeing to safety.
The Competence Shock Frameworkinsight
Justin Wolfers argues the market is reacting not just to an oil shock but to a "competence shock" — the U.S. appears to have no plan, no allies announced, and no exit strategy, making every new statement a major signal.
Avoid America Versus Sell Americainsight
Katie Martin clarifies that the "sell America" narrative is wrong. Investors aren't selling existing U.S. holdings; they're directing new capital toward Europe, Asia, and emerging markets instead of mechanically allocating 60-70% to the U.S.
Gasoline Prices as Political Constraintdata
Katie Martin notes U.S. gasoline prices rose 16% in a week to an average of $3.48 per gallon. She argues this political liability is what caused the administration to soften its language on Iran.
Iraq War Market Impact Datadata
Justin Wolfers cites his own research from the Iraq war buildup: a 10% increase in the probability of war moved U.S. stocks by 1.5 percentage points, implying the full conflict would wipe 10 to 15% off the market.
War Duration Forecasts Off by 365xdata
Justin Wolfers references Rumsfeld's "six days, six weeks, six months" prediction for Iraq, which took over six years. He argues early forecasts can be wrong by a factor of more than 365, and investors should multiply their best guesses accordingly.
Iran Can Keep Hormuz Closed Indefinitelyinsight
Katie Martin argues that regardless of what Trump wants, Iran has the drones to keep the Strait of Hormuz under pressure indefinitely. An Iranian minister confirmed the strait is closed and they will keep it closed.
Autocrat Project Undoes Economic Resiliencedebate
Justin Wolfers pushes back on Katie's market resilience argument, arguing the deeper question is how far Trump will go as an autocrat. He compares the U.S. to Turkey, Hungary, and Argentina, where autocratic rule destroyed institutions and economic potential for a century.
Ed Elson is joined by Katie Martin and Justin Wolfers to break down how the war with Iran is moving markets, what signals the bond market is sending, and where the economy could go from here. Katie Martin is a markets columnist and editorial board member at the Financial Times. Justin Wolfers is a Professor of Economics and Public Policy at the University of Michigan.
