National Context
What is the Net Interest Margin?
Net Interest Margin measures net interest income (interest earned minus interest paid) against average earning assets. It is the core spread the bank earns from its primary business — lending deposits at higher rates than they cost.
Most US community banks report NIM between 2.8% and 4.0%. Higher is generally better but reflects either premium lending (higher-yielding loans) or low-cost funding (large core deposit franchise). Falling NIM in a rising-rate environment signals the bank's deposit costs are catching up to its asset yields.
