Effective Federal Funds Rate

## What this measures

The effective federal funds rate is the volume-weighted median rate at which depository institutions lend reserves to one another overnight on an unsecured basis. It reflects the actual clearing price in the federal funds market each day.

## Why it matters

This rate anchors the short end of the yield curve and influences the cost of credit throughout the economy. When the realized rate drifts outside the Federal Reserve's target range, it signals supply or demand imbalances in bank reserves that can affect funding conditions and the transmission of monetary policy. Organizations that borrow, invest or manage cash positions use it to gauge the immediate cost of liquidity.

## How to read it

A rising rate indicates tightening in overnight funding markets; a falling rate suggests easier conditions. Compare the effective rate to the Federal Reserve's target range to see whether the market is clearing within, above or below the intended band. Persistent deviations signal operational or structural pressure in the interbank lending market.

## What it does not say

The rate does not reveal the Federal Reserve's target or future policy intentions. It reflects only where transactions occurred, not the credit quality of borrowers or the availability of reserves to all institutions.
