To identify the correct statement regarding monetary policy instruments, an examination of each option's definition and economic policy function is required:
- Cash Reserve Ratio (CRR): This ratio mandates that a bank hold a specific percentage of its total deposits in reserve, either as physical cash or with the central bank. Although it impacts bank lending capacity and, consequently, the money supply, it does not directly influence the inflation rate.
- Discount Rates: These are the interest rates set by the central bank for loans extended to commercial banks. While they shape the money supply by altering borrowing expenses, they are not the primary mechanism for direct money supply control.
- Both (1) and (2) are correct: Considering the preceding analyses, neither option (1) nor option (2) accurately describes a direct impact on inflation or a direct control over the money supply.
- Open Market Operations (OMOs): OMOs encompass the central bank's transactions in buying and selling government securities on the open market. These operations serve as a principal method for managing the money supply, controlling interest rates, and influencing banking system liquidity.
Based on these descriptions, the accurate statement is that Open Market Operations consist of the buying and selling of government securities.
