For banking along Spring Street in La Mesa Village, Union Bank operated under the Mitsubishi UFJ Financial Group umbrella before its December 2022 acquisition by U.S. Bancorp. Originally chartered in 1914 as Kaspare Cohn Commercial & Savings Bank in Los Angeles, the institution maintained consumer and commercial deposit services at this location, with real estate loan closings notarized through providers like Tower Mobile Notary Services. The U.S. Bancorp acquisition closed on December 1, 2022, for approximately $8 billion in combined cash and stock, integrating Union Bank's 398-branch California, Washington, and Oregon network into the U.S. Bank system. Legacy wealth management clients transitioned trust, estate, and fiduciary services during the conversion period, needs also served by independent firms such as Banks & Banks Fiduciary Services. Former account holders were migrated to U.S. Bank routing numbers and digital banking platforms during the first half of 2023, completing the full systems conversion. Highest-value legacy products included MUFG-backed international wire transfer corridors, multi-currency commercial deposit accounts, and Japanese yen-denominated trade finance instruments tied to Pacific Rim import-export transactions.
