The resolution to this apparent puzzle is that when one bank decides to hold a lower balance in its reserve account, the funds it sheds necessarily end up in the account of another bank, leaving the total unchanged (see FT Alphaville and this New York Fed Current Issues in Economics and Finance article for more detailed discussions of this point). In the aggregate, therefore, these balances do not represent âidleâ funds that the banking system is unwilling to lend. In fact, the total quantity of reserve balances held by banks conveys no information about their lending activities â it simply reflects the Federal Reserveâs decisions on how many assets to acquire.
A cut in the IOR would probably lead to a rush into short-term USTs, the price would get to a point where banks would not buy them any longer. Deposits at the fed would remain unchanged. The excess reserves 'sitting at the fed and not being lent' as same people put it will not change until the fed wants it to change
