Money is often misunderstood as a commodity that “has” intrinsic value. In reality, modern currency functions as a record of debt—an IOU—whose worth depends on the creditworthiness of the issuer and the flow of goods, services, and debt denominated in that currency. Understanding this framework explains why some currencies remain relatively stable while others, such as many cryptocurrencies, experience wild swings.
Money is an IOU, Not a Commodity
- IOU concept: When one party promises to deliver value in the future, the promise itself (the IOU) becomes the medium of exchange. The physical paper or digital entry has no inherent value; the value lies in the expectation that the issuer will honor the promise.
- Creditworthiness matters: The worth of an IOU is tied to the issuer’s ability and willingness to fulfill it. If the issuer is reliable, the IOU retains value; if not, its value collapses.
- Collateral effect: When an IOU is backed by assets that lose value, the IOU’s purchasing power declines accordingly.
Why Commodity‑Based Money Is Inefficient
- Resource waste: Extracting and processing precious metals (e.g., gold) consumes energy and labor that could be used for productive purposes.
- Price distortion: Tying money to scarce resources creates artificial demand for those resources, driving up the cost of real goods and services that rely on them.
Price Stability Comes From Real‑World Pricing
- Goods and services anchor currency: When a broad range of products is priced in a particular currency, demand for that currency stabilizes. If nothing is priced in the currency, its value can fluctuate wildly.
- International trade balance: Cross‑border purchases create natural demand for the currency of the exporting country. For example:
- If the Canadian dollar weakens, U.S. buyers purchase Canadian goods at lower prices, increasing demand for CAD and helping to stabilize its value.
- Conversely, if Canadian goods become more expensive, Canadians may seek U.S. dollars to buy cheaper foreign products, again providing a balancing effect.
Debt as the Primary Driver of Currency Demand
- Debt denominated in a currency creates demand: Global debt obligations (e.g., mortgages, corporate bonds) that must be repaid in a specific currency generate continuous demand for that currency, regardless of other factors.
- Illustrative case: During the March 2020 market crash, the U.S. dollar surged because worldwide dollar‑denominated debt required repayment, pulling capital into the dollar.
Implications for Cryptocurrencies
- Lack of backing: Most cryptocurrencies are not tied to real‑world assets or debt, so they lack the stabilizing demand that traditional currencies enjoy.
- Pricing mismatch: If a house is priced in Bitcoin, the transaction directly supports Bitcoin’s value. However, when Bitcoin is merely exchanged for fiat to purchase the house, the price stability still depends on the fiat currency, not on Bitcoin itself.
- Resulting volatility: Without widespread pricing of goods, services, or debt in a cryptocurrency, its value remains highly volatile.
Practical Takeaways
- Assess currency stability by looking at the volume of real‑world transactions and debt denominated in that currency.
- Be cautious of commodity‑based money proposals that ignore the resource costs and price distortions they introduce.
- For investors in cryptocurrencies, recognize that price stability will likely improve only if the token becomes a standard unit of account for a significant share of global trade or debt. Until then, expect higher volatility compared to fiat currencies backed by extensive real‑economy usage.
