Episode notes
Hierarchy of Money Explained
- Money is a superior means of payment used to settle debts, qualitatively different from credit which is a promise to pay money.
- The global monetary system forms a hierarchy with the U.S. dollar at the top, and crypto lies outside and tries to replace this system but is stress-tested now.
Money as Means of Settlement
- Money's defining feature is being a means of settlement, not simply low risk or wide acceptance.
- Both mainstream economics and crypto undervalue money's liquidity and settlement role, leading to flawed theories.
Elasticity to Discipline Shift
- Financial systems' elasticity allows rolling over debts easily in good times, but the pandemic response led to elasticity giving way to stricter discipline.
- Crypto, as a newcomer, fails first in this shift since it lacks central bank backstops and robust settlement mechanisms.
