About RSI Bank


RSI Bank has been a constant in the community since 1851.

RSI Bank is known as a safe, trusted and highly reputable institution – a brand that signifies “community” and “caring” at its core. As New Jersey’s oldest mutual savings bank, RSI Bank has endured and even thrived during some of our country’s most challenging periods – from the Civil War through the current COVID-19 pandemic. 

RSI Bank was incorporated by an act of New Jersey State Legislature on February 19, 1851 (then known as Rahway Savings Institution), and opened its doors to the public on March 12, 1851. Today, RSI Bank has 4 offices in Union County and Middlesex County: one office in downtown Rahway, one on Saint Georges Avenue on the border of Rahway and Linden, one office in Colonia, and one in Woodbridge, NJ.

Thanks to its capital strength, and a foundation based on integrity and honesty, RSI Bank remains a fiscally solid provider of banking products and financing solutions. What’s more, the bank continues to stand out for its commitment to personalized attention and exceptional service, as well as the range of quality products and expertise extended to the community.

RSI Bank celebrates 170 years as a community bank and as a generous supporter of education, the arts, public safety and wellness initiatives that improve the lives of local residents. 

Treating people fairly, with consideration and respect, is a long held, fundamental credo of RSI Bank that guides our company’s mission as a community bank. RSI Bank unequivocally prioritizes fairness and justice and is anti-racism. This shared belief drives our leadership, core business model, community partnerships and charitable donations, as well as our normal course of doing business.
