Understanding the national debt and the risks of a fiscal crisis

For the first time since the end of World War II, the national debt held by the public — $31.5 trillion — is roughly the same size as the entire U.S. economy. And in just over two decades the debt could be 50% larger than gross domestic product, according to Congressional Budget Office projections. What are the sources of this unprecedented rise in federal debt? Watch this recording of a webinar held on July 14, 2026, co-hosted with EconoFact, a non-partisan website from Tufts University, to find out. Panelists cover: What's behind the rise in federal debt? How was high debt brought down after World War II and are there lessons for today from that experience?

How does high debt tie the government’s hands and limit its ability to address challenges? Does high debt lead to inflation? How and when does a fiscal problem become a fiscal crisis, and what happens then?
