Types of discount rates
Although we refer to the discount rate as a singular number, the Fed actually has three rates it uses for the discount window, depending on the bank it's lending to:
- The primary credit rate is the rate offered to most financial institutions. It's usually set about 1 percentage point higher than the federal funds rate, which is the rate at which the Fed suggests commercial banks lend to one another. The primary credit rate is what's referred to when discussing the discount rate in general.
- The secondary credit rate is offered to banks that don't qualify for the primary credit rate. It's usually about 0.5 percentage points higher than the primary credit rate.
- The seasonal credit rate is for smaller banks that need funds to meet local borrowing needs. These are typically seasonal needs such as farming operations, vacation resorts, or schools and students. The rate for seasonal credit is an average of selected markets.
How the Fed used the discount rate to manage the pandemic
In February and March of 2020, the COVID-19 pandemic led governments to enact safety protocols, pushing many businesses to close their doors and consumers to stay home. Workers were furloughed, events were canceled, and the government action -- while necessary for public safety -- caused an economic downturn.
The Fed was able to step in with a series of measures to help prop up the economy in the short term. One move was to lower the federal funds rate to a target between 0% and 0.25%. It also lowered the discount rate to 0.25% while extending the discount window lending period to 90 days.
These changes, combined with government lending programs for small businesses and stimulus checks for individuals, helped the economy bounce back quickly. However, those same moves -- combined with global supply chain challenges -- led to inflation. While originally considered "transitory," the Fed changed its tune in late 2021 and began taking action to curb inflation in early 2022.
The Fed raised the discount rate to 0.5% in early 2022, and it will continue to make increases to move the inflation rate closer to its target of around 2%. It must be careful, however, to balance its contractionary policies with the economy.
Limitations of the discount rate
Although the Fed can steer lending and banking activity by adjusting the discount rate, there are still some limitations.
For one, the Fed has said it doesn't want to lower the rate into negative territory. Other central banks have done so in the past to spur economic activity, but the Fed has said it won't go below zero. A negative interest rate implies banks would get paid to use money from the Federal Reserve.
But the Fed can use its open market operations to influence interest rates and lending activity. If it wants banks to hold more cash, it can buy securities from member banks. While it doesn't directly provide cash, it creates a credit on the banks' balance sheets, which is treated like cash. As such, banks can make more loans and at lower interest rates since the money supply is effectively increased.
Using the discount rate in conjunction with open market operations gives the Fed better control over the money supply and the direction of the economy. However, it's still impossible to predict exactly how a Fed policy change will affect the economy. Although changes in the discount rate have a directionally accurate impact on the economy, it's hard to hit the targets right on the head.
