The Board of Governors of the Federal Reserve System is requesting comment on the proposal to lower the interest rate on excess balances of eligible institutions that hold a very large proportion of their assets in the form of reserves—i.e., on balances of ‘The Narrow Bank.’
The document states that
[t]he Board is concerned that [Pass-Through Investment Entities] PTIEs, by maintaining all or substantially all of their assets in the form of balances at Reserve Banks and having the ability to attract very large quantities of deposits at a near-IOER rate, have the potential to complicate the implementation of monetary policy.
