U.S. Banks Cost of Funding Earning Assets (FDIC)

## What this measures

Total interest expense (on deposits and borrowings) in the quarter, annualized, as a percent of average earning assets, for all FDIC-insured institutions.

## Why it matters

It shows how fast banks pass higher market rates on to depositors and lenders. A rapid rise squeezes the net interest margin and signals competition for deposits, as after 2022.

## How to read it

It follows the federal funds rate with a lag. The gap between yield on earning assets and this cost is the net interest margin (credit.banks.qbp.nim).

## What it does not say

It covers FDIC-insured commercial banks and savings institutions (insured branches of foreign banks are left out), not credit unions or nonbank lenders. It is an industry figure: the largest banks move it most, and it says nothing about any one bank. The FDIC revises recent quarters as banks amend their Call Reports.
