The Fiat Standard — Lecture 15 (Bitcoin Banking) • Study Notes

Overview

  • Banking historically provides two essential services:
  1. Custody (deposit banking): keeping money safe and accessible.
  2. Investment allocation: channeling capital into productive enterprises.
  • Under fiat, both functions have been distorted by inflation, debt, and state monopolies.
  • Question: How would banking work under a Bitcoin standard with fixed supply money?

This lecture explores custody, investment, savings evolution, and why Bitcoin likely leads to equity-based banking instead of debt-based banking.

1. Custody (Deposit Banking)

  • Homes are not designed as vaults; specialized custodians provide security.
  • In a Bitcoin world:
  • Custodians will still exist.
  • Clients trade off some censorship resistance for convenience.
  • Risk of abuse is limited because:
    • Bitcoin is cheap and easy to withdraw on-chain (~500k daily transactions available).
    • Users can take custody at any time.
  • Key point: Even if much Bitcoin is custodied, monetary policy remains secure as long as individuals retain exit options.

2. Investment Allocation

  • Banks act as intermediaries: match savers with businesses needing capital.
  • Requires human judgment (entrepreneurship) — cannot be automated fully.
  • Two models:
  1. Credit-based lending (interest).
  2. Equity-based investment (ownership shares).

In fiat, credit dominates because debt = money creation. In Bitcoin, equity will dominate (explained below).

3. Evolution of Savings

  • Gold standard: saving was simple — hold gold coins.
  • Fiat eras:
  • Bank deposits → inflation eroded value.
  • Bonds → became “savings accounts” but eroded over time.
  • Stocks (index funds) → became surrogate savings vehicles, detached from fundamentals.
  • Real estate, art, gold, etc. → pressed into service as savings due to fiat decay.
  • Result: individuals juggle complex portfolios just to preserve wealth.
  • Bitcoin fixes this:
  • High salability across time and space.
  • No yield = no distortion from monetary demand.
  • Returns simplicity: saving = holding Bitcoin.

4. Bitcoin Demonitizes Assets

  • In fiat, stocks, bonds, and houses are treated as money → inflated valuations.
  • In Bitcoin:
  • Houses = consumer goods (not savings vehicles).
  • Stocks = real investments (valued on dividends, not “store of value”).
  • Bonds = largely unnecessary.
  • Bold prediction: Bitcoin may end the bond market.
  • Bonds exist because fiat credit creation rewards lending.
  • Without inflationary credit, bonds lose purpose.
  • Bitcoin provides better liquidity and homogeneity than bonds (all satoshis are fungible).

5. Fragility of Fiat vs. Robustness of Bitcoin

  • Fiat system: built entirely on debt → fragility.
  • Bank runs, crises, contagion.
  • Needs central banks as “lenders of last resort.”
  • Bitcoin system:
  • Value not dependent on credit repayment.
  • Final settlement always possible on-chain.
  • Removes systemic fragility from interconnected debt webs.

6. Why Equity > Debt in Bitcoin Banking

Three main reasons:

  1. No more money-printing via debt
  • Lending doesn’t “mine” new money.
  • Removes artificial incentive for credit expansion.
  1. No lender of last resort
  • Credit = high risk of total loss.
  • Without bailouts, fixed-interest contracts are unsustainable.
  • Equity absorbs risk honestly (both upside & downside).
  1. Cash abundance & declining interest rates
  • Hard money encourages accumulation of cash balances.
  • More savings → lower interest rates.
  • Austrian view: interest = measure of civilization/time preference.
  • Trend over 5,000 years: falling interest rates → eventually ~0% nominal.
  • At 0% nominal, lending unattractive → equity dominates.

7. The Endgame: Banking on a Bitcoin Standard

  • Banking separates cleanly into two roles:
  1. Deposit banking: full-reserve custody, funded by depositor fees.
  2. Investment banking: equity investment, maturity-matched, sharing upside & downside.
  • Credit shrinks to marginal role (loans among family/friends).
  • Broader system = more robust, less fragile, equity-driven finance.

Key Takeaways

  1. Custody remains but is disciplined by Bitcoin’s withdrawability.
  2. Investment allocation persists but shifts from debt to equity.
  3. Bitcoin restores saving simplicity — just hold Bitcoin.
  4. Bonds lose purpose without fiat’s debt-creation incentive.
  5. Interest rates trend toward 0% nominal as time preference declines.
  6. Equity-based banking becomes dominant: honest risk-sharing replaces fixed-interest illusions.

Conclusion:
Bitcoin banking = full-reserve custody + equity finance. This eliminates fiat’s debt fragility, collapses the bond market, and restores stability to global finance.
