In short: Founded in a single room in 1889, Northern Trust has grown into a financial titan overseeing trillions in assets. By prioritizing stability over aggressive expansion, the firm famously navigated the Great Depression and the 2008 financial crisis, maintaining its reputation as one of the oldest banks in continuous operation.

Northern Trust began on August 12, 1889, in Chicago’s Rookery Building, established by Byron Laflin Smith with $137,981.25 in initial deposits. From its inception, the bank focused on trust and banking services for the city's elite, backed by prominent shareholders like Marshall Field and Philip D. Armour. This conservative ethos proved foundational; while many competitors collapsed during the Great Depression, Northern Trust saw its assets grow. By 1941, the bank had expanded its reach significantly, with nearly half of its commercial accounts originating outside the Chicago metropolitan area.

The institution’s resilience was tested again during the early 1980s when exposure to Latin American debt and falling oil prices threatened profitability. Under the leadership of Weston Christopherson, who took the helm in 1984, the bank utilized aggressive loan reserves and write-offs to restore asset quality. By his retirement in 1990, the bank had become the 11th most profitable among the 100 largest U.S. banks. This culture of stability persisted into the 21st century; during the 2008 financial crisis, Northern Trust was one of only two banks in the S&P 500 that did not lower its dividends.

Today, the corporation operates as a global financial services provider with a massive footprint in asset servicing and wealth management. As of late 2025, it ranked 269 on the Fortune 1000, managing $1.8 trillion in assets and holding $14.9 trillion in custody. The firm serves a diverse clientele, ranging from ultra-high-net-worth families—over 20% of the wealthiest in the U.S. are clients—to sovereign wealth funds and foundations. Despite its size, the bank maintains a commitment to philanthropy, historically donating approximately 1.5% of its pre-tax profits to charitable organizations annually.
