In 1914, Kaspare Cohn founded Kaspare Cohn Commercial & Savings Bank in Los Angeles. It was renamed Union Bank & Trust Company of Los Angeles in 1918. Harry Volk was recruited from Prudential Insurance Company as the bank's new CEO in 1957 and pioneered the use of the one-bank holding company, among other banking innovations.  Volk retired in 1980 after the purchase of the bank by London-based Standard Chartered Bank in 1979.

Three years later, Union Bank was again accused of money-laundering and in September 2007, the bank agreed to pay $31.6 million in penalties and forfeitures to settle government claims that it had been implicated in an elaborate drug money laundering scheme involving Mexican exchange houses known as casas de cambio.
