Net Interest Income

Table 3: Summarized Average Balances and Net Interest Income (a)

(a)Interest income calculated as taxable-equivalent interest income. To provide more meaningful comparisons of interest income and yields for all interest-earning assets, as well as net interest margins, we use interest income on a taxable-equivalent basis in calculating average yields and net interest margins by increasing the interest income earned on tax-exempt assets to make it fully equivalent to interest income earned on taxable investments. This adjustment is not permitted under GAAP on the Consolidated Income Statement. For more information, see Reconciliation of Taxable-Equivalent Net Interest Income (non-GAAP) in the Statistical Information (Unaudited) section in Item 1 of this Report.

Changes in net interest income and margin result from the interaction of the volume and composition of interest-earning assets and related yields, interest-bearing liabilities and related rates paid, and noninterest-bearing sources of funding. See the Statistical

Information (Unaudited) – Average Consolidated Balance Sheet And Net Interest Analysis section of this Report for additional information.

Net interest income increased $108 million, or 3%, and net interest margin increased 4 basis points compared to the second quarter of 2024 driven by higher yields on interest-earning assets. In the year-to-date comparison, net interest income decreased $537 million, or 5%, and net interest margin decreased 18 basis points, as the benefit of higher interest-earning asset yields was more than offset by increased funding costs.

Average investment securities increased $1.0 billion, or 1%, compared to the second quarter of 2024 primarily driven by net purchase activity of U.S. Treasury securities. Average investment securities decreased $1.7 billion, or 1%, in the year-to-date comparison as net purchase activity was more than offset by portfolio paydowns and maturities. Average investment securities represented 28% of average interest-earning assets for the third and second quarters of 2024, and 27% for the first nine months of 2024 compared to 28% for the first nine months of 2023.

Average loans were stable for the third quarter of 2024 compared to the second quarter of 2024. Compared to the first nine months of 2023, average loans decreased $3.1 billion, primarily due to lower average utilization of commercial loan commitments. Average loans represented 62% of average interest-earning assets for the third quarter of 2024 compared to 63% for the second quarter of 2024, and 62% for the first nine months of 2024 compared to 64% for the first nine months of 2023.

Average interest-earning deposits with banks for the third quarter of 2024 increased $4.2 billion, or 10%, compared to the second quarter of 2024, primarily reflecting deposit growth. In the year-to-date comparison, average interest-earning deposits with banks increased $10.3 billion, or 30%, due to higher borrowed funds and lower loan and securities balances, partially offset by lower deposits.

Average interest-bearing deposits for the third quarter of 2024 increased $5.4 billion, or 2%, compared to the second quarter of 2024 and $8.8 billion, or 3%, in the year-to-date comparison. The increase in both comparisons reflected growth in commercial deposits, partially offset by a decline in consumer balances. In total, average interest-bearing deposits represented 81% of average interest-bearing liabilities for both the third and second quarters of 2024, and 81% for the first nine months of 2024 compared to 83%, for the first nine months of 2023.

Average borrowed funds decreased $1.4 billion, or 2%, compared to the second quarter of 2024, reflecting lower FHLB borrowings, partially offset by parent company senior debt issuances. Compared to the first nine months of 2023, average borrowed funds increased $11.0 billion, or 17%, primarily due to parent company senior debt issuances.
