open market operations or open market-type operations

[Анна Ф]

The level of development, structure, and depth of the markets will affect which money market instruments are likely to perform better (open market operations or open market-type operations) and which auction technique can be used to structure these operations (Box 4.3).

• Open market-type operations, which are market-based monetary operations based on auction techniques regulated by the central bank. OMO-type operations involve: (1) lending/borrowing against underlying assets as collateral; (2) primary market issuance of central bank securities or government securities for monetary policy purposes; and (3) acceptance of fixed term-deposits.
• Open market operations (OMOs), which are market-based monetary operations conducted by the central bank as a participant in the money market. These involve: (1) buying/selling assets outright on the secondary market; and (2) buying/selling assets in the repo market or through foreign exchange swaps.
