Since the two-week MNB bill comprises the bulk (nearly 40 per cent) of the securities pledged by banks as collateral, the central bank decision will definitely require some adjustment on the part of credit institutions if they wish to maintain the level of liquidity previously available for them in the payment systems. In our paper, we examine the possible adjustments of banking sector participants in response to the conversion of the MNB bill into deposits in terms of liquidity and, based on historical data, we attempt to analyse the impact on credit institutions resulting from the removal of the MNB bill from the pool of eligible collateral.
