3.88% for 2023, a decrease of 14 basis points. Average interest earning assets increased $8.8 million during 2024, primarily in CRA mortgage-backed securities as part of our CRA strategic plan, partially offset by a reduction in interest-earning deposits with banks and a slight reduction in average loans as we tightened underwriting and focused on quality growth in the powersport business during this macro-economic cycle. The overall yield on earning assets increased 71 basis points to 7.46% in 2024, from 6.75% in 2023, primarily from the higher rate powersport portfolio. Interest-bearing liabilities increased $11.4 million while overall cost of funds increased 98 basis points to 4.34% as a result of the higher rate environment in all funding costs as compared to 2023. The change in the deposit mix reflects a significant increase in online savings deposits as a result of the success of our national digital deposit strategy and a decrease in reliance on fixed rate CD funding and wholesale funding. This strategy is expected to be favorable in a declining interest rate environment.
