A Federal Reserve rate hike is very likely to occur before the end of the year or in Q1. But many are still unclear about how the Federal Reserve will raise rates. After all, we’re in a new monetary environment in the post-crisis period thanks to the size of the Fed’s balance sheet. I’ll try to touch briefly on this to clarify some concerns.

In the pre-crisis period the Fed set a target rate for the overnight interest rate and altered the quantity of reserves in the banking system. Banks are required to hold some reserves and this allowed the Fed to act as a sort of monopolist in the overnight market. Increasing or decreasing the quantity of reserves allowed the Fed to set a target price and influence it by altering supply. More reserves would put downward pressure on rates, for instance. This is a rather crude explanation, but it’s close enough.

In the post-crisis period the Fed operates in a whole new paradigm. Because Quantitative Easing has expanded the Fed’s balance sheet there is no scarcity issue in the overnight market for reserves. This has put tremendous pressure on overnight interest rates, but the Fed was given Congressional authority to pay interest on excess reserves which allows the Fed to set a floor on the overnight rate. Banks wouldn’t lend at a rate lower than what they can earn on reserves so this allows the Fed to achieve its target rate without having to change the quantity of reserves.¹

There’s a problem with this framework, however. The Fed market is comprised of some entities that the Fed does not have authority to pay interest to. Because of this the Fed has been forced to expand its list of potential counterparties so it can implement a reverse repo facility that will operate similarly to paying interest on excess reserves to primary dealers. Since the Fed doesn’t have authority to pay interest to some entities in the overnight market it has experienced trouble with its target rate whereby downward pressure on rates is still exacerbated by these other firms. This repo facility will allow the Fed to “clean up” this excess price discrepancy and better target an overnight rate.
