What makes money… money? And who should we trust to issue it?

In this episode of Econ To Go, Neale Mahoney sits down with Stanford finance professor Amit Seru to explore the tug-of-war over the future of money. Stablecoins promise fast, low-cost digital payments, but Seru explains why they function much like narrow banks — vulnerable to runs if confidence erodes. The conversation examines the GENIUS Act’s attempt to add guardrails for this unique type of crypto, the risks of delegating core financial functions to private issuers, and why trust remains the foundation of any stable currency. We cover several key themes, including:

• (01:10) What’s at stake: Stablecoins and the future of money
• (05:35) The GENIUS Act: What it does, what it doesn’t
• (09:44) Run risk, backstops and regulatory gaps
• (14:34) Private innovation and public power
• (20:40) American trust in digital money
• (26:50) To buy or not to buy
