Final answer:
In 2020, during the COVID-19 pandemic, the Federal Reserve likely lowered the Interest on Reserve Balances (IORB) to stimulate the economy, as indicated by the reduction of the federal funds rate from over 2% to 0.05% in March 2020.
Step-by-step explanation:
The Interest on Reserve Balances (IORB) is a monetary policy tool used by the Federal Reserve to influence the economy. In Episode 9, during the Great Recession of 2008, the Federal Reserve aggressively cut interest rates to nearly 0% by 2009 as the economy was deep in recession.
Similarly, in response to the economic shock of the COVID-19 pandemic in 2020, historical patterns suggest that the Federal Reserve would also lower interest rates to stimulate economic activity. Specifically, from the information given, the federal funds rate was over 2% and was reduced to 0.05% in March 2020, which indicates a significant reduction in IORB as well.
