Mercer Savings Bank is a small community bank headquartered in Celina, Ohio, serving rural communities in western Ohio and eastern Indiana. The bank was originally chartered in 1888 and converted from mutual to stock form in July 2023. Mercer Savings operates six branch offices and had roughly $176M in total assets. The bank's core business is originating loans funded by retail deposits. Its loan portfolio is concentrated in residential mortgage loans (55% of total loans) and agricultural real estate loans (32%), with the remainder in home equity lines, construction, consumer/auto, and modest commercial loans. The agricultural focus reflects the heavily rural local economy, which includes farming of soybeans, corn, and wheat, as well as poultry, egg, and pork production. Like most community banks, Mercer Savings earns net interest income on the spread between deposit costs and loan yields. Core deposits fund roughly 65% of total deposits and are relatively low-cost. A large share of the loan book is long-dated, creating interest rate risk; the bank manages this by selling certain fixed-rate residential mortgages upon origination and growing its shorter-duration indirect auto loan program. Fee income is modest, primarily gains on sale from selling residential mortgages into the secondary market. The bank's primary market covers Mercer and Darke Counties in Ohio and Adams and Jay Counties in Indiana, with a combined population of roughly 151,000. Mercer Savings is gradually expanding its Indiana footprint, opening a new Berne, Indiana branch in 2025.
