🕰️ Background
Bitcoin (2009) and subsequent cryptocurrencies challenge central bank monetary policy by proposing decentralized alternatives to government-issued currency. Bitcoin’s fixed supply (21M coins) contrasts with fiat currency’s unlimited supply, appealing to those who distrust central bank money printing. Crypto markets reached 1T (2022).
❓ The Central Problem
Does cryptocurrency represent a viable alternative monetary system or a speculative asset? The case examines whether Bitcoin fulfills the three functions of money (medium of exchange, store of value, unit of account) and how central bank digital currencies (CBDCs) might respond.
📊 Analysis
As medium of exchange: crypto is slow, expensive, volatile — poor for daily transactions. As store of value: Bitcoin’s fixed supply resists inflation but price volatility (80% crashes) undermines stability. As unit of account: no economy prices goods in crypto. Central bank response: CBDCs (digital yuan, digital euro) aim to capture crypto’s technology advantages while maintaining monetary policy control. The fundamental tension: Bitcoin’s deflationary design (fixed supply) would create the monetary policy problems of the gold standard — inability to respond to recessions with monetary expansion.
🔑 Key Lessons
- A fixed money supply prevents monetary policy response to recessions — Bitcoin’s design recreates gold standard limitations
- Cryptocurrency currently functions as a speculative asset rather than money — it fails all three money functions at scale
- Central bank digital currencies (CBDCs) represent the institutional response — digital technology without abandoning monetary policy
- Decentralization vs. stability is a fundamental tradeoff — the reasons money is centrally managed are the reasons crypto is volatile
🎓 Discussion Questions
- Can Bitcoin or any cryptocurrency ever become a widely-used medium of exchange? What would need to change?
- Should central banks view crypto as a threat to monetary sovereignty or an irrelevant speculative market?
- Would a Bitcoin standard perform better or worse than the current fiat system during a financial crisis?
