SUMMARY The money market, a segment within the financial market, facilitates short-term borrowing and lending, typically involving instruments maturing within a year. Vital for managing liquidity and fulfilling short-term financial needs of various entities like governments, financial institutions, and corporations, it includes significant tools such as Treasury Bills (T-Bills), Commercial Bills, Commercial Papers (CPs), and Certificates of Deposits (CDs). T-Bills, for instance, represent secure government debt with maturities ranging from 91 days to 1 year, issued at a discount and redeemed at face value. Commercial Bills, on the other hand, are issued by businesses to cover working capital requirements, traded in secondary markets, and overseen by the RBI. Meanwhile, CPs serve as unsecured, short-term corporate debt, offering a flexible and cost-efficient option compared to conventional loans. CDs, being negotiable bank deposits with fixed maturities, present higher interest rates and are deemed low-risk. Recently, there has been a notable shift towards green investments within the money market, embracing environmentally sustainable assets like green bonds and renewable energy initiatives. These investments strive to marry financial gains with positive environmental outcomes. Despite their potential for diversification and higher returns, challenges such as limited availability, elevated costs, and uncertain financial performance persist. To encourage green investments, recommendations include bolstering transparency, raising awareness, integrating environmental considerations into financial strategies, and fostering collaboration among governmental bodies, regulatory agencies, and stakeholders to nurture the expansion of these sustainable financial avenues.
