About this series
The Federal Funds Effective Rate — the volume-weighted average rate at which US banks lend reserves to each other overnight. Published daily by the New York Fed.
Why it matters: DFF is how the Fed's policy decisions actually transmit to the real economy. When the FOMC raises or lowers its target range, this is the rate they're targeting. It sets the floor for all other short-term borrowing costs — money market funds, bank deposits, credit card APRs, and the short end of the yield curve all move with it.
How to read it: Look at both the level and the direction. The level tells you whether monetary policy is tight (above ~3%) or loose (below ~2%). The direction tells you the Fed's stance. Pay attention to the spread between DFF and 10Y Treasury yield (DGS10) — when DFF exceeds DGS10, you have an inverted curve, historically a recession signal.
Caveats: This is the *effective* rate, not the target. The target comes as a range (e.g., 4.25-4.50%) which we don't currently store.
