Economic Moats
An economic moat is a durable competitive advantage that helps protect a company’s profits from competition. Its value depends on how long the advantage lasts; investment returns also depend on the price paid.
THE IDEA
In business, I look for economic castles protected by unbreachable ‘moats.’
—Warren Buffett
The economic moat is the competitive advantage that allows a company to protect its value and achieve higher long-term returns.
Buffett compares durable business advantages with the defensive moats around castles. The question is what protects a company’s profits and how competitors might overcome that protection.
Remember that a competitive advantage is essentially any factor that allows a company to provide a good or service that is similar to those offered by its competitors and, at the same time, outperform those competitors in profits. A good example of a competitive advantage would be a low-cost advantage, such as cheap access to raw materials.
Very successful investors such as Buffett have been adept at finding companies with solid economic moats but relatively low share prices.

FROM THEORY TO EVERYDAY LIFE
In practice
Low-Cost Advantage
A mining company gains a cost advantage by owning high-grade ore deposits close to the surface, giving it lower extraction costs than rivals.
Switching Costs
A SaaS company with deeply integrated accounting software creates high switching costs; clients face significant data migration and retraining expenses if they move to a competitor.
Network Effects
A social media platform becomes more valuable as more users join, making it hard for competitors to attract users away from the established network.
A MOMENT TO REFLECT
Put it to work.
Think of a company you admire. What is its economic moat, and how durable is it?
How could a competitor erode a company's moat over time?
In your own career or projects, what moats can you build to protect your value proposition?
