Net interest income is the difference between interest income and fees earned on loans and investments (“interest-earning assets”) and interest expense incurred on deposits and borrowings (“interest-bearing liabilities”). Interest rate levels and volume fluctuations within interest-earning assets and interest-bearing liabilities impact net interest income. Net interest margin is tax-equivalent net interest income as a percent of average interest-earning assets.

Certain assets with tax favorable treatment are evaluated on a tax-equivalent basis, assuming a federal income tax rate of 21.0%. Tax favorable assets generally have lower contractual pre-tax yields than fully taxable assets. A tax-equivalent analysis is performed by adding the tax savings to the earnings on tax favorable assets. After factoring in the tax favorable effects of these assets, the yields may be more appropriately evaluated against alternative earning assets. In addition to yield, various other risks are factored into the evaluation process.

The following table presents, for the major components of interest-earning assets and interest-bearing liabilities, a breakout of changes in interest income and interest expense attributable to (1) changes in average volume and (2) changes in average yield. For purposes of this table, changes attributable to both rate and volume, which cannot be segregated, have been allocated proportionately, based on changes due to rate and changes due to volume(dollars in thousands):

The FOMC raised rates by a total of 100 basis points during 2023, and by a total of 525 basis points since the onset of the current FOMC tightening cycle that began in the first quarter of 2022. Rising rates initially have a positive impact on net interest margin, as assets, in particular commercial loans, reprice more quickly and to a greater extent than liabilities. As deposit and funding costs increase in response to the tightening rate cycle, and we experience deposit migration into higher cost offerings and funding alternatives, some of the net interest margin expansion is reversed.

Net interest spread represents the difference between the average rate earned on earning assets and the average rate paid on interest-bearing liabilities, and is presented in the table below for the periods indicated:
