Other borrowings may include federal funds purchased, repurchase agreements and borrowings from the Federal Reserve through the FRDW and BTFP. Southside Bank has three unsecured lines of credit for the purchase of overnight federal funds at prevailing rates with Frost Bank, Amegy Bank, TIB – The Independent Bankers Bank for $40.0 million, $25.0 million and $15.0 million, respectively. There were no federal funds purchased at December 31, 2024 or 2023. To provide more liquidity in response to economic conditions in recent years, the Federal Reserve has encouraged broader use of the discount window. At December 31, 2024, the amount of additional funding the Bank could obtain from the FRDW, collateralized by securities, was approximately $431.7 million. There were no borrowings from the FRDW at December 31, 2024, and $300.0 million at December 31, 2023. To provide more stability and to assure banks have the ability to meet the needs of all of their depositors, the Federal Reserve created the BTFP in the first quarter of 2023. On March 11, 2024, the Federal Reserve stopped extending new BTFP advances. There were no remaining borrowings from the BTFP at December 31, 2024, compared to $117.7 million at December 31, 2023. Southside Bank has a $5.0 million line of credit with Frost Bank to be used to issue letters of credit, and at December 31, 2024, the line had one outstanding letter of credit for $155,000. Southside Bank currently has one outstanding letter of credit from FHLB held as collateral for a loan for $6.1 million.
Southside Bank enters into sales of securities under repurchase agreements. These repurchase agreements totaled $76.4 million at December 31, 2024, and $92.1 million at December 31, 2023, and had maturities of less than one year. Repurchase agreements are secured by investment and MBS securities and are stated at the amount of cash received in connection with the transaction.
FHLB borrowings represent borrowings with fixed interest rates ranging from 0.27% to 4.80% and with remaining maturities of 2 days to 3.8 years at December 31, 2024.  FHLB borrowings may be collateralized by FHLB stock, nonspecified loans and/or securities.
