Episode notes
America's Large On- and Off-Balance Debt
- The federal debt held by the public is about $30 trillion, roughly 100% of GDP, creating large interest expenses near $1 trillion per year.
- Off-balance-sheet obligations for Social Security and Medicare add roughly $100 trillion in present-value liabilities, effectively doubling fiscal exposure.
Markets Signal Calm Despite Big Debt
- Current market rates imply a low real government borrowing cost (real rates near zero), signalling that markets are calm about U.S. finances.
- A flat term structure and subdued real yields suggest market confidence even amid high debt levels.
Political Economy Trumps R vs G
- The fiscal outcome depends less on R versus G arithmetic and more on political economy: willingness to tax or cut spending.
- Historical U.S. episodes (WWII, COVID) show rapid policy shifts, which markets price as capacity to adjust when needed.
