CDSL

If you opened a demat account through one of India's popular discount brokers, there is a strong chance your shares are held with CDSL. Set up in 1999, it is the second of India's two depositories — and it has become the runaway leader in the one metric that captures the retail investing boom: the number of demat accounts. The question it answers: where are the tens of crores of new Indian investors keeping their shares?

What CDSL does

Like its older sibling NSDL, CDSL is a SEBI-regulated market infrastructure institution that holds securities electronically — shares, bonds, mutual funds and more. You never deal with it directly; you open an account via a Depository Participant (your broker or bank), and CDSL maintains the underlying electronic record. When you buy or sell, the change of ownership is ultimately an entry updating in the depository's books, which is what allows smooth settlement on the NSE and BSE.

The retail giant

CDSL's defining feature is its dominance of retail accounts. It holds the large majority of India's demat accounts — roughly four out of five — and has crossed successive milestones into the multiple-crore range as first-time investors poured in through app-based brokers during the post-2020 retail surge. It captures the bulk of *new* accounts opened each year. In a notable distinction, CDSL was the first depository to list on the stock exchanges, making it directly investable — and a kind of barometer of India's retail equity boom, since its revenues rise with account numbers and market activity.

CDSL versus NSDL

The two depositories are interoperable, so investors rarely notice which one holds their securities. The rough split: CDSL leads on the sheer number of retail accounts, while NSDL leads on the value of assets and institutional custody. Having two independent depositories adds resilience to the system — a failure or outage at one does not freeze the whole market.

The takeaway: CDSL is the quiet infrastructure behind India's democratisation of stock ownership. Its account numbers double as a real-time gauge of how many Indians are entering the markets — which is why both investors and policymakers watch them closely.
