Open Market Operations (OMO) are transaction in the money market and/or foreign exchange market conducted by Bank Indonesia with Banks and/or other parties for monetary operation in a conventional manner and based on sharia principles. OMO in domestic currency is divided into two, namely OMO absorption and OMO injection, considering liquidity conditions in the banking system both conventional and sharia. OMO absorption is performed to absorb excess liquidity while OMO injection is undertaken to increase liquidity in order to maintain a balance of liquidity conditions to support the achievement of monetary operations target. OMO can be carried out regularly and non-regularly. Regular OMO is  conducted on a scheduled basis through an auction. Meanwhile, non-regular OMO can be conducted at any time (fine-tune operation) to strengthen the achievement of monetary operations target through the implementation of regular OMO. BI announces plans and results of regular and non-regular OMO auctions through the website of BI and/or other designated means.
