To determine the rate, the BTFP uses the fixed OIS rate based on the effective federal funds rate for a one-year maturity. Effective January 24, 2024, the FRB announced that future advances under the BTFP through its expiration on March 11, 2024, would be no lower than the interest rate on reserve balances in effect on the date the advance is made.

The Company had $19.5 million and $19.2 million in other borrowings at March 31, 2024 and December 31, 2023, respectively. These borrowings consist of short-term repurchase agreements with certain commercial demand deposit customers for sweep accounts. The repurchase agreements typically mature within one to three days and the interest rate paid on these borrowings floats monthly with money market type rates. The interest rate paid on the repurchase agreements was 1.49% at March 31, 2024 and December 31, 2023.
