Those increases reflect the deployment of liquidity into primarily fixed rate mortgage-backed investment securities classified in the Company's available-for-sale investment securities portfolio. As a result of the purchases of higher-yielding securities and the maturities of lower-yielding securities, the weighted-average current yield for total investment securities available for sale increased to 4.65% at September 30, 2025 and 4.50% at June 30, 2025 as compared with 4.08% at September 30, 2024. The weighted-average duration of the available-for-sale investment securities portfolio was 2.5 years at September 30, 2025 as compared with 2.6 years and 2.3 years at June 30, 2025 and September 30, 2024, respectively. The Company routinely adjusts its holdings of capital stock of the FHLB of New York and the FRB of New York based on amounts of outstanding borrowings and available lines of credit with those entities.

The Company regularly reviews its debt investment securities for declines in value below amortized cost that might be indicative of credit-related losses. There were no credit-related losses on debt investment securities recognized in each of the nine months ended September 30, 2025 and 2024. A further discussion of fair values of investment securities is included herein under the heading "Capital." Additional information about the investment securities portfolio is included in notes 3 and 13 of Notes to Financial Statements.

Other earning assets include interest-bearing deposits at banks and trading account assets. Those other earning assets in the aggregate averaged $17.8 billion and $19.8 billion for the three-month periods ended September 30, 2025 and June 30, 2025, respectively, and $19.1 billion and $28.6 billion for the nine months ended September 30, 2025 and 2024, respectively. The amounts of other earning assets at those respective dates were primarily comprised of deposits held at the FRB of New York. In general, the levels of those deposits often fluctuate due to changes in deposits of retail and commercial customers, trust-related deposits, brokered deposits and additions to or maturities of investment securities or borrowings.
