Frequently asked

What is the Federal Funds Rate?
The interest rate at which banks lend reserve balances to each other overnight. The FOMC sets a target range and uses the IORB and ON-RRP rates to keep the effective rate inside it.
How often does the Fed change rates?
The FOMC meets eight times per year. It can also act between meetings in emergencies (e.g., March 2020).
What is the difference between the target rate and effective rate?
The target is the FOMC range (e.g., 5.25% to 5.50%). The effective rate (EFFR) is the volume-weighted median actually transacted in the fed funds market each day.
How does the Fed Funds Rate affect markets?
It anchors the entire short end of the yield curve, drives the dollar via rate differentials, and is the single biggest input to risk-asset valuations.
