Certificates of deposit (CDs) are short-term deposit instruments issued by banks and financial institutions to raise large amounts of money. CDs can be issued with maturities ranging from 7 days to 12 months by banks and 1 to 3 years by financial institutions. They must be purchased in amounts of at least Rs. 1 lakh. Banks and corporations use CDs to mobilize funds when needed, such as providing loans. CDs provide liquidity to banks while offering depositors higher returns than regular fixed deposits. However, the CD market in India has yet to be fully developed due to the lack of a secondary market and low usage despite being available for some time.
