State Street Corporation traces its origins to 1792, when it was founded in Boston as Union Bank, one of the first banks chartered in the United States. Over the 19th and early 20th centuries, it evolved alongside the growth of American commerce, eventually adopting the State Street name in 1966 to reflect its longstanding presence on Boston’s financial thoroughfare. The firm transformed itself in the late 20th century from a traditional commercial bank into a global leader in custody banking, asset servicing, and institutional investment management, serving many of the world’s largest asset managers, pension funds, and sovereign wealth funds. A defining milestone came in 1993 with the launch of the SPDR S&P 500 ETF, the first exchange-traded fund in the United States, which helped reshape modern investing. Today, State Street is one of the largest custodians globally, overseeing tens of trillions of dollars in assets under custody and administration while maintaining a central role in the infrastructure of global financial markets.
