MUFG Union Bank (stylized as UnionBank) is an American full-service bank with 398 branches in California, Washington and Oregon which is wholly owned by The Bank of Tokyo-Mitsubishi UFJ. The bank, formerly known as Union Bank of California, N.A., has operations in California, Washington and also has commercial branches in Dallas, Houston, New York City and Chicago, as well as two international offices. Headquartered in New York City, MUFG Union Bank, N.A. is a subsidiary of holding company MUFG Americas Holdings Corporation and a member of the Mitsubishi UFJ Financial Group (NYSE: UFG).
As of December 31, 2014, MUFG Americas Holdings Corporation had $113.7 billion (USD) in assets and the Mitsubishi UFJ Financial Group had total assets of approximately $2.3 trillion (USD). Its foundation is built on five lineages; three originate in California and two in Japan.
In May 1996, Mitsubishi Bank and the Bank of Tokyo merged in Japan. In San Francisco, the Bank of California and Union Bank consolidated into UnionBanCal Corporation, a bank holding company, and its primary subsidiary Union Bank of California, N.A. With the merger, Union Bank could now trace its history back to the founding of the Bank of California 132 years before. In 1999, UnionBanCal Corporation became a publicly traded company listed on the New York Stock Exchange (NYSE:UB).
On October 19, 2004, the Federal Reserve Board announced that Union Bank had entered into a written agreement to avoid criminal prosecution for money-laundering. Three years later, Union Bank was again accused of money-laundering and in September, 2007, the Department of Justice and the Treasury Department announced that Union Bank had 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.
In August 2008, Mitsubishi UFJ offered to buy the 35 percent of Union Bank it did not already own, which Union Bank accepted. On November 4, 2008, the Bank of Tokyo-Mitsubishi UFJ (BTMU), a wholly owned subsidiary of Mitsubishi UFJ Financial Group (MUFG), announced that BTMU had successfully acquired all of the outstanding shares of UnionBanCal Corporation.
In 2014, MUFG integrated the U.S. operations of its subsidiary The Bank of Tokyo-Mitsubishi UFJ, Ltd. (BTMU) with those of San Francisco-based Union Bank, N.A.
In 2009, Union Bank opened a branch in Texas, with plans to expand.
On April 30, 2010, Union Bank, N.A., acquired certain assets and assumed certain liabilities of Everett, Washington-based Frontier Bank in a purchase and assumption agreement with the Federal Deposit Insurance Corporation (FDIC). Twelve officers and corporate directors of Frontier Bank are facing a $46 million damage lawsuit filed by the FDIC.
Also in April, Union Bank acquired the assets of Tamalpais Bank in Marin County, including seven branches. Federal regulators sold Tamalpais' assets to Union Bank, which rebranded all the acquired branches.
In 2013, Union Bank completed the acquisition of First Bank Association Bank Services, which provides a full range of banking services to homeowners associations and community management companies. The acquisition brought to Union Bank approximately $550 million in deposits.
PurePoint Financial, the savings only division of MUFG Union Bank, offers high interest rates on savings accounts and certificates of deposit. 
Union Bank's Board of Directors approves the bank's Community Service Action Plan (CSAP), which is used to ensure the bank's compliance with Community Reinvestment Act requirements. The CSAP targets seven key areas for support and services: affordable housing, banking services, community outreach, corporate contributions, low-income consumer loans, small business loans and assistance, and supplier diversity.
