The Negotiated Dealing System (NDS) is an electronic trading platform established by the Reserve Bank of India in 2002 to facilitate the issuance and trading of government securities and money market instruments. It replaced the inefficient manual trading methods with a system that improves liquidity, transparency, and cost-effectiveness in both primary and secondary markets. The NDS includes two modules for primary and secondary markets and offers several benefits for both the RBI and investors, including enhanced trading efficiency and easier access to investments.
