Bhaskar Joshi presented on depository services in India. A depository allows investors to hold financial assets like stocks, bonds, and mutual funds in dematerialized electronic form. There are two main depositories in India - NSDL and CDSL. Depositories work through depository participants like banks and brokers. Benefits of the depository system include eliminating paperwork, providing faster transfers, and reducing risks of lost certificates. However, the system also introduces risks like potential for uncontrolled trading if not properly regulated. NSDL and CDSL maintain electronic records of share and debt holdings and facilitate transactions.
