Net Interest Income and Net Interest Margin

2024 Net Interest Income

Net interest income is the interest earned on debt securities, loans, and other interest-earning assets less interest paid for interest-bearing deposits and other borrowings. The net interest margin is calculated by dividing tax-equivalent net interest income by average interest-earning assets. Net interest spread is the difference between the average rate earned on interest-earning assets and the average rate paid on interest-bearing liabilities. Net interest margin is typically greater than net interest spread due to interest income earned on assets funded by non-interest bearing liabilities such as demand deposits and equity.

Tax-equivalent net interest income totaled $1.2 billion for 2024, a decrease of $61.1 million compared to the prior year. Net interest income was reduced $58.0 million due to changes in interest rates. Net interest income decreased $3.1 million from growth in average assets and interest-bearing deposit balances, partially offset by lower wholesale borrowings. Table 3 shows the effects on net interest income due to changes in average balances and interest rates for the various types of earning assets and interest-bearing liabilities. In addition, see the Annual Financial Summary of consolidated daily average balances, yields and rates as shown in Table 2.

Net interest margin was 2.65% for 2024 and 2.93% for 2023. Our core net interest margin excluding trading activities1, a non-GAAP measure, was 3.01% compared to 3.31% in the prior year. In response to rising inflation, the Federal Reserve increased the federal funds rate 525 basis points during 2022 and 2023. The resulting impact on market interest rates increased net interest margin at first as our earning assets, led by our significant percentage of variable-rate commercial loans, repriced at a higher rate and faster pace than our interest-bearing liabilities. Throughout 2023 and 2024, we have experienced margin compression reflecting deposit repricing activity and demand deposit migration into interest-bearing accounts. This compression began to slow in September 2024, following a series of rate cuts totaling 100 basis points through the end of the year. The tax-equivalent yield on earning assets was
