Total deposits increased $49 million from December 31, 2023 to $5.1 billion as of September 30, 2024. Total Core Bank deposits increased by $257 million, or 6%, from December 31, 2023. Within the Core Bank’s deposits, interest-bearing deposits increased $338 million and noninterest-bearing deposits decreased $81 million.
The increase in Core Bank interest-bearing deposits was driven by $225 million of growth in money market deposits and, a $76 million increase in reciprocal money market deposits, and a $16 million increase in time deposits. The growth in money market and reciprocal money market deposits was primarily in exception-priced accounts as well as those products marketed with standard higher offering rates. The growth in savings deposit balances was driven primarily by funds received from a third-party listing service.
During the first nine months of 2024, noninterest-bearing deposit balances continued their downward trend, while interest-bearing categories generally increased. This trend was generally the result of the attractive yields available on interest-bearing deposit accounts as compared to noninterest-bearing alternatives, which provide no yield to the depositor.
RPG Deposits
As previously noted in the Company’s 2023 Report on Form 10-K filed on March 14, 2024, RPS began sharing a significant portion of the interest revenue it earns on its prepaid card balances with its prepaid card marketer-servicers during the first quarter of 2024. This revenue share is being reported as interest expense on deposits. As a result, all prepaid card deposit balances subject to a revenue share arrangement will be reported as interest-bearing deposits on an on-going basis, as long as they remain subject to a revenue share arrangement. Conversely, for any periods reported prior to 2024, these deposits will remain noninterest-bearing as they were not subject to a revenue share arrangement during those periods.
As a result of all the factors noted above, Management believes the Company is more likely to experience slower overall growth and possibly, a continuing decline in its noninterest-bearing deposits over the foreseeable future.
Federal Home Loan Bank Advances
The Bank’s total FHLB advances were $370 million as of September 30, 2024 compared to $380 million as of December 31, 2023. There were no overnight borrowings as of September 30, 2024 compared to $110 million as of December 31, 2023. The Company has utilized FHLB advances over the past year to partially fund its noninterest-bearing deposit outflow and overall loan growth.
During the second quarter of 2024, the Bank elected to extend $100 million of FHLB borrowings during May and June through a third-party, fixed rate swap to take advantage of the inverted yield curve and lower its overall borrowing costs. As a result of this swap, the Bank was able to lock in an annualized cost of 4.42% for this $100 million over a five-year term.
As of September 30, 2024, the Company’s $370 million of FHLB advances had a weighted-average maturity of 2.53 years and a weighted-average cost of 4.52%, both including the impact of the related swaps. Overall use of FHLB advances during a given year is dependent upon many factors including asset growth, deposit growth, current earnings, and expectations of future interest rates, among others.
Interest Rate Swaps
The Bank enters into interest rate swaps to facilitate client transactions and meet their financing needs. Upon entering into these instruments, the Bank enters into offsetting positions in order to minimize the Bank’s interest rate risk. These swaps are derivatives, but are not designated as hedging instruments, and therefore changes in fair value are reported in current year earnings.
In addition, as noted in the section above, the Company entered into $100 million of notional amount balance sheet related interest rate swaps during the second quarter of 2024 in order to take advantage of the more attractive long-term pricing resulting from the inverted yield.
See Footnote 12 “Interest Rate Swaps” of Part I Item 1 “Financial Statements” for additional discussion regarding the Bank’s interest rate swaps.
Liquidity
The Bank maintains sufficient liquidity to fund routine loan demand and routine deposit withdrawal activity. Liquidity is managed by maintaining sufficient liquid assets, primarily in the form of cash, cash equivalents, and unencumbered investment securities. Funding
