### Key findings and observations
- Most central banks oblige depository institutions to hold minimum reserves against their liabilities, predominantly in the form of balances at the central bank.
- The role of reserve requirements has evolved significantly over time.
- The overlay of changing purposes and practices has resulted in situations where it is not always fully clear what the current purpose of reserve requirements is.
- Unclear purpose complicates the design and structure of a reserve regime.
- The paper identifies three main purposes for reserve requirements:
  - Prudential
  - Monetary control
  - Liquidity management
- The paper illustrates current practices using a 2010 IMF survey of 121 central banks.

### Analysis and implications
- Evolving and overlapping purposes (prudential, monetary control, liquidity management) create trade-offs and implementation challenges for central banks when structuring reserve regimes.
- Ambiguity about the primary objective of reserve requirements affects decisions on levels, composition (e.g., balances at the central bank vs. vault cash), and supporting operational frameworks.
- Understanding contemporary practices (as reported in the 2010 IMF survey of 121 central banks) is important for benchmarking and designing best-practice reserve frameworks.

### Suggested best practices (as discussed in the paper)
- Structure reserve regimes with clarity on primary objectives (prudential, monetary control, or liquidity management).
- Align reserve instrument composition and operational details with the identified primary objective(s).
- Use international practices (e.g., findings from the 2010 IMF survey of 121 central banks) to inform reforms and operational implementation.
