PFS Bancorp is the holding company for Peru Federal Savings Bank, a small community savings bank headquartered in Peru, Illinois. Peru Federal operates out of two offices in Peru, Illinois, serving a rural market across LaSalle County and parts of adjacent Bureau and Putnam counties. The bank's core business is traditional: it takes deposits from local residents and businesses and lends that money out, primarily as residential mortgage loans. One-to-four-family residential mortgages make up roughly 60% of the loan portfolio, offered as fixed- or adjustable-rate products for terms up to 30 years, and held mostly on the bank's own balance sheet rather than sold into the secondary market. Peru Federal has been deliberately expanding into commercial real estate loans (roughly 24% of the portfolio) and commercial business loans (roughly 5%), aiming to improve portfolio yield over time. The bank earns revenue almost entirely from interest income; noninterest income is not meaningful. Net interest margin is the key profit driver, and deposit costs are central to managing that margin — time deposits (CDs) make up roughly 45% of total deposits and carry higher rates than other deposit types. Peru Federal funds itself entirely through deposits, with no reliance on wholesale borrowings. The bank converted from mutual to stock form in October 2023, raising capital in the process. At year-end 2025, Peru Federal had total assets of $207M, loans of $109M, and deposits of $166.5M.
