In banking, excess reserves are
bank reserves in excess of the reserve
requirement set by a central bank. They are
reserves of cash more than the required amounts.
Holding excess reserves has an opportunity cost
if higher risk-adjusted interest can be earned by
putting the funds elsewhere; the advantage of
holding some funds in excess reserves is that
doing so may provide enhanced liquidity and
therefore more smooth operation of payment
system.
