makes the case that it could be different this time around with the Fed's legal authority to pay interest on reserves.
I must admit, however, that I’m perplexed that so many pundits put so much emphasis on the importance of the Fed soaking up excess reserves, as if it is a necessary condition for hiking the Fed funds rate. It is not. To be sure, it used to be, before the Fed had the legal authority to pay interest on reserves, which Congress granted last fall. Before then, the only way the Fed could achieve a meaningfully positive Fed funds rate target was to constrain the supply of reserves relative to the banking system’s demand for reserves, essentially required reserves.
If there were excessive excess reserves, then the Fed funds rate would fall below the Fed’s target, as banks with excess would be willing to lend them out in the Fed funds market below the Fed funds target, given that if they simply left them at the Fed, they would earn nothing. But now, the Fed pays interest on banks’ excess reserves (presently at an interest rate of 0.25%, the top of the Fed’s 0% – 0.25% target band for the Fed funds rate). Thus, logic says that banks with excess reserves will not lend them in the Fed funds market at a rate appreciably lower than the Fed pays, but simply leave them on deposit at the Fed. Accordingly, the rate that the Fed pays on excess reserves should now act as a proximate floor for the Fed funds rate, even if there are huge excess reserves in the system. Thus, by hiking the rate it pays on excess reserves, the Fed now has the ability to enforce a rising Fed funds rate target – even before it “unwinds” its bloated balance sheet.
Sure they have the authority, but do they have the political will?
