What is the Cash Management Meaning in Banking?
In the context of the Indian economy, cash management refers to the strategic process of monitoring and balancing the government’s short-term cash inflows (taxes, revenues) and outflows (expenditures).
When a temporary mismatch occurs, where spending exceeds available cash, the government reaches for Cash Management Bills (CMB). Introduced in 2010, these are non-standard, short-term money market instruments that act as a "bridge" to ensure fiscal operations run smoothly without the need for long-term borrowing.
Features and Benefits of Cash Management Bills India
