Episode notes
Fed Rate Hikes Limited By Federal Interest Expense
- The Fed can't materially hike rates without triggering unsustainable federal interest expense pressures.
- John Arnold shows Debt/GDP and non-discretionary spending math that leaves little room for higher blended interest costs without political cuts or fiscal coordination.
Treasury Volatility Risks A Levered Degrossing Cycle
- Rising volatility in Treasury markets increases fragility because levered hedge funds hold large treasury basis positions.
- Arnold cites the MOVE index spike and how degrossing amid volatility can cascade into a vicious cycle on the Treasury bedrock.
Government Coordination Can Break Normal Policy Constraints
- In extreme shocks governments' institutions correlate and coordinate policy tightly, changing normal constraints.
- Arnold uses the 1940s example of Fed-Treasury coordination, price controls, and rationing to show how yields stayed low despite high inflation.
