Preferred Bank (Chinese: 保富銀行) is a California state-chartered bank founded in 1991 to serve the Chinese American community in Southern California.

The bank expanded in 2015 through acquisition after facing inadequate leverage ratios and concerns about management from its regulator in 2010.

In its early years the bank focused its services on the Chinese American community in Southern California.

An inadequate leverage ratio and concerns about management led to a consent decree in March 2010, later lifted and replaced with a memorandum of understanding, in which California banking regulators required the bank to review its management policies and increase its liquidity.

[6] The loan obligations taken on as part of the acquisition increased its percentage of problem assets significantly, and after losing money on the disposal of problem assets, the company returned to a focus on local business rather than acquisitions.
