Definition
An Economic Moat is a distinct advantage that a business has over its competitors, allowing it to protect its long-term profits and market share. The term was popularized by Warren Buffett as a metaphor for a medieval castle’s moat.
Why It Matters
Without an economic moat, any profitable business will eventually be competed down to zero margins. Moats are the only thing that protects long-term value creation. Companies that fail to identify and widen their moats are inevitably disrupted by more efficient or innovative newcomers.
Core Concepts
- Network Effects: The value of the service increases as more people use it (e.g., Metcalfe’s Law).
- Switching Costs: The expense or effort required for a customer to move to a competitor (e.g., proprietary software ecosystems).
- Intangible Assets: Brand recognition, patents, or regulatory licenses.
- Cost Advantage: The ability to produce goods at a lower cost than competitors (e.g., economies of scale).
- Efficient Scale: A market that is only large enough to support one or two players, discouraging new entrants.
