- Why high profits are self-destructing unless something protects them
- The seven kinds of moat, with Indian examples of each
- How to see a moat widening or narrowing in the numbers, before the narrative changes
Your friend's tea stall does brilliantly — ₹5 lakh profit on ₹10 lakh invested. A 50% return.
Now watch what happens next. His neighbour notices. Within a year there are three tea stalls on that street. To keep customers, everyone drops the price. Within two years all three are earning a modest, ordinary living.
This is not bad luck. It is the default outcome of capitalism: high returns attract capital until the returns are no longer high. The interesting question is not "why do most businesses earn ordinary returns?" It's "how does any business keep earning extraordinary ones for twenty years?"
The answer is always the same: something stops the neighbour from opening the second stall. That something is the moat.
A moat is not a good product or a nice brand. A moat is a structural reason a competitor cannot take your customer, even by offering a lower price.
The seven kinds of moat
- Brand / pricing powerHow it works: Customers pay more for the same functional thing, out of trust or identityWhere you see it: Paints, biscuits, jewellery, premium two-wheelers
- Switching costHow it works: Changing supplier is painful, risky or expensive — even when a rival is cheaperWhere you see it: Enterprise software, IT services, banking relationships
- Network effectHow it works: Each extra user makes the product more valuable to every other userWhere you see it: Exchanges, marketplaces, payment networks, job portals
- Cost advantageHow it works: Structurally cheaper production — location, scale, captive raw materialWhere you see it: Cement near limestone, integrated steel, large-scale mining
- Regulatory / licenceHow it works: The law limits who may compete at allWhere you see it: Banking licences, depositories, exchanges, defence, tobacco
- Efficient scaleHow it works: The market is only big enough to support one or two players profitablyWhere you see it: Utilities, gas distribution in a city, regional airports
- Distribution reachHow it works: Getting to millions of small outlets takes decades to replicateWhere you see it: FMCG rural networks, large paint and cement dealerships
How a moat shows up in the numbers
This is the part most people miss. A moat is a qualitative idea, but it leaves quantitative fingerprints — and the fingerprints are more reliable than the story, because the story is written by the company.
- ROCE above 20% for ten yearsWhy it's evidence: Competitors have had a decade to compete the returns away and failed
- Gross margin stable through an input-cost spikeWhy it's evidence: The company passed the cost to customers — that is pricing power, demonstrated
- Market share stable or rising for yearsWhy it's evidence: Not buying share with discounts, not losing it either
- Low capital intensity with high growthWhy it's evidence: Growth doesn't require constant reinvestment — an intangible advantage is doing the work
- Pricing above peers, sustainedWhy it's evidence: Customers are choosing to pay more with alternatives freely available
Raw material prices jumped 30% across the industry in one year. Watch what each company's gross margin did.
- Company A — gross margin before
- 48%
- Company A — gross margin after
- 46%
- Company B — gross margin before
- 34%
- Company B — gross margin after
- 19%
Moats erode — and the numbers say so first
No moat is permanent. Technology dissolves switching costs, regulation opens up protected industries, distribution advantages evaporate when everything ships from a warehouse. What matters for you is that erosion is visible in the financials well before it's visible in the narrative.
- ✓Gross margin trending up over five years
- ✓ROCE stable or rising as the business grows
- ✓Market share gains without price cuts
- ✓Growing revenue per employee (services businesses)
- ✓Customers renewing at higher prices
- ✕Gross margin sliding a point or two every year
- ✕Advertising spend rising just to hold share
- ✕Discounting appearing in management commentary
- ✕New entrants funded aggressively and undercutting on price
- ✕ROCE drifting down toward the sector average
A great product. Products get copied. The moat is whatever stops the copy from winning.
Being the biggest. Size only helps if it produces lower unit costs or a network effect. Large and undifferentiated is just a bigger target.
A famous name. Brand awareness is not pricing power. The test is whether customers pay more — many famous Indian brands compete entirely on price.
Being first. First movers are frequently overtaken by whoever executes better with a lower cost base.
Government protection you can't rely on. A tariff or licence granted this year can be withdrawn next year. Treat policy-based moats as rented.
Look at any industry where a protected incumbent lost. The financial sequence is almost always the same, and it runs for years before the headlines catch up.
First gross margin slips a point a year — dismissed as "competitive intensity". Then advertising or discounting rises to defend volumes. Then market share starts falling despite the extra spend. Only then does profit fall, and only then does the narrative change to "disruption".
Anyone tracking the gross margin line had a three-to-five year head start on anyone reading the news.
- 1Why does the customer buy from this company rather than the cheapest option? If you can't answer in one sentence, there may be no moat.
- 2What would it take for a well-funded competitor to take 20% of this business? If the answer is "money and eighteen months", the moat is thin.
- 3Has ROCE stayed above 20% for a decade? Ten years of high returns is competition's failed attempt, recorded.
- 4Did gross margin survive the last input-cost spike? The free stress test.
- 5Is the advantage widening or narrowing? Read the last five years of margin and share, not the last quarter.

- 1High returns attract competition; a moat is whatever stops competition from taking them.
- 2Seven types: brand, switching cost, network effect, cost advantage, regulation, efficient scale, distribution.
- 3Moats leave fingerprints — a decade of high ROCE, margins that survive cost spikes, share held without discounting.
- 4Erosion is visible in gross margin and market share years before it reaches profit.
