Exchange & Depository Moats in India: All 8 Scored
This sector contains the highest raw score on the entire site — and it still is not a wide moat. The National Stock Exchange scores 7.69 on MoatSCORE 6.0, ahead of every other company we have scored, and the framework still classifies it NARROW. The reason is the single most important thing to understand about exchange moats in India: the liquidity is real, and the licence to operate it is not owned.
Where the moat actually sits
Averaged across all 8 exchanges companies, the strongest dimension is Efficient Scale (6.21) and the weakest is Switching Costs (4.85). Network effects dominating this sector is exactly what theory predicts — liquidity attracts liquidity, and an order book is the textbook case. The gap between that strength and the final scores is regulatory, not competitive.
| Dimension | Sector average | Coverage |
|---|---|---|
| D6 Efficient Scale | 6.21 | 8/8 |
| D1 Network Effects | 6.00 | 8/8 |
| D3 Cost Advantage | 5.88 | 8/8 |
| D5 Intangible Assets | 5.52 | 8/8 |
| D4 Price Discretion | 5.11 | 8/8 |
| D2 Switching Costs | 4.85 | 8/8 |
Coverage shows how many companies had enough evidence to score that dimension. A dimension scored for only a handful of companies is a thin signal, not a sector verdict.

Why the top score is still capped
An exchange's liquidity pool is a genuine network effect and nobody disputes it exists. The gate that caps it asks a different question: who owns the walls? Transaction fees are regulator-capped. Licences are granted and can be re-granted. And in the case of power trading, the regulator has been asked to examine market coupling — a mechanism that would pool every exchange's order book into one government-run engine, converting the moat into a public utility. A moat held on licence from an entity with both the intent and the machinery to fill it in is, by construction, narrow.

Method and limits
Scores come from MoatSCORE 6.0, applied to filings, annual reports and earnings-call transcripts. Two independent runs on the same evidence must land within half a point. Where we find no evidence for a claimed moat, we record that as a finding rather than a gap. The full cross-sector table is on the Moat Screener.
