Episode notes
Fiscal Deficits Have Reshaped Cycles
- Sustained large fiscal deficits have already changed economic cycles and muted traditional indicators like the yield curve.
- Lyn Alden argues deficits have mattered for years and will continue to shape outcomes over the next 5–10 years.
Dollar's Network Effect Buys Time
- The dollar benefits from entrenched, contractual demand such as $18 trillion of offshore dollar debt that slows rapid collapse.
- That network effect gives the U.S. a longer runway even as optional demand can evaporate quickly.
Politics, Not Just Numbers, Can Trigger Collapse
- Political shocks, not macro accounting, are likelier to trigger rapid unwinding of dollar dominance.
- Nonlinear moves include contract changes, defaults, capital controls, or sudden geopolitical realignments.
