The Bitcoin Standard — Lecture 3 (Monetary Metals) • Study Notes
By Saifedean Ammous
Big Picture
- For ~2,000 years, the world’s dominant monies were metals.
- Gold and silver emerged as the leading monetary metals, with gold ultimately winning because of its hardness and durability.
- The introduction of coinage standardized weight and purity, improving salability and enabling global trade.
- The competition between gold and silver ended with the demonetization of silver in the 19th century.
- Gold’s high stock-to-flow ratio made it the hardest money prior to Bitcoin.
Core Claims
- Why Metals Became Money
- Metals are durable, divisible, portable, and widely recognizable.
- Coinage increased trust and standardization, making trade more efficient.
- Gold: most saleable across time and space.
- Silver: most saleable across scales (smaller transactions).
- Gold vs. Silver
- Gold: indestructible, high stock-to-flow (~60), best long-term store of value.
- Silver: useful for small denominations, but lower stock-to-flow (now ~3).
- Industrial use and susceptibility to rust/decay weakened silver’s role.
- The Fall of Silver
- Rise of banking, telegraph, and railroads enabled paper claims to replace physical coins.
- Once paper substitutes existed, gold-backed paper outcompeted silver-backed paper.
- Franco-Prussian War (1870s) was the tipping point: reparations demanded in gold → silver collapsed as money.
- Long-term result: demonetization of silver, destruction of Indian rupee relative to British gold-backed pound.
- The Hunt Brothers’ Silver Pump (1980)
- Attempted to corner silver market by buying up supply.
- Price rose to $50/oz → triggered massive new production and recycling (silverware melted).
- Supply expansion crushed price → silver exposed as “easy money” with no difficulty adjustment.
- Gold’s Unique Properties
- Annual new supply ~1.5–2%, stable for centuries.
- Accumulated stock never decays.
- High stockpile size vs. flow prevents inflationary collapse.
- Still held by central banks today (~10x more than during gold standard).
- Historical Lessons
- Rome: prosperity rose with coinage, collapsed with debasement and inflation.
- Byzantium: the solidus/bezant coin held weight/purity for ~1,000 years, creating stability.
- Medieval Renaissance: Florence’s florin & Venice’s ducat fueled trade and capital accumulation.
- 19th–early 20th century: global gold standard created predictable, fixed exchange rates across nations.
Key Concepts & Mental Models
- Saleability → across time (gold), scales (silver), space (portable coins).
- Stock-to-flow ratio → ultimate measure of hardness.
- Demonetization → gradual collapse of silver as money.
- Difficulty adjustment → Bitcoin’s key innovation preventing supply inflation.
- Extent of the market (Adam Smith) → grows with sound, uniform money.
Examples & Applications
- Gold Coin ≈ Cow: storing value over decades.
- Silver as “working man’s money” vs. gold as “king’s money.”
- Byzantine Solidus: 4.5g of gold, stable for centuries, still recognized today.
- Indian Rupee vs. British Pound: silver vs. gold → long-term wealth divergence.
- Modern Central Banks: still hoard gold while issuing fiat.
Quotable Ideas
- “Silver is the original shitcoin.” — Ammous
- “Gold’s hardness is its difficulty adjustment: stockpiles never decay.” — Ammous
- “Civilizations rise on sound money and collapse when it is debased.” — Mises (paraphrased)
- “The bezant was the only altcoin worth respecting.” — Ammous
Study Prompts
- Why did coinage transform the role of metals as money?
- Compare gold’s saleability across time vs. silver’s saleability across scales.
- Explain how the telegraph and railroads undermined silver’s role.
- What killed silver as money after the Franco-Prussian War?
- Why did the Hunt brothers’ attempt to corner silver fail?
- How did the Byzantine solidus maintain stability for 1,000 years?
- Why is the 19th-century gold standard seen as a high point in monetary history?
TL;DR
Metals became money because they were durable, divisible, and portable. Gold emerged as the hardest money due to its indestructibility and high stock-to-flow ratio, while silver fell behind once banking allowed paper substitutes to replace small-denomination coins. The Franco-Prussian War sealed silver’s demonetization, leaving gold as the global standard. History shows civilizations flourish with hard money and collapse with debasement. Gold was the best monetary technology before Bitcoin — which improves on it with built-in difficulty adjustment and incorruptibility.
