What is Business Cycle Theory?
The Austrian Business Cycle Theory (ABCT), developed by Mises and Hayek, explains that the cause of boom-bust cycles lies in artificial credit expansion by central banks.

Mechanism
Step 1: Artificial Interest Rate Reduction
Central banks lower interest rates below the market equilibrium level. This sends a false signal to the market that "savings have increased."
Step 2: Malinvestment
Deceived by low interest rates, businesses invest in long-term projects - real estate development, factory construction, startups, and more. In reality, there are insufficient real resources (savings) to complete these projects.
Step 3: False Boom
As credit expands, the economy appears to be thriving. Asset prices rise, unemployment falls, and everything looks good.
Step 4: Return to Reality (Bust)
The projects initiated by false signals prove impossible to complete. Businesses fail, asset prices crash, and recession arrives.
Step 5: Necessary Adjustment
The recession is not an illness but a healing process. Misallocated resources are redirected to their proper uses. Interference with this adjustment (additional credit expansion, bailouts) makes the problem worse.
Historical Examples
- 2008 Financial Crisis - Federal Reserve's low interest rate policy → housing bubble → collapse
- Dot-com Bubble (2000) - Federal Reserve's credit expansion → tech stock bubble → collapse
- Great Depression (1929) - 1920s credit expansion → stock market bubble → collapse
In all cases, the pattern is identical: artificial credit expansion → false boom → inevitable collapse.
Bitcoin and Business Cycles
The ABCT cycle is unlikely to occur in a Bitcoin economy:
- Fixed Supply - Central banks cannot expand credit
- No Artificial Interest Rate Manipulation - Interest rates reflect market time preference
- No Bailouts Possible - The costs of misguided investments cannot be transferred to others
