Definition and formula
A regional bank is a bank with $10 billion to $100 billion in total assets. No statute defines the term; this list uses the Federal Reserve's band, whose Supervision and Regulation Report (June 2026) groups US banking organizations with total assets between $10 billion and $100 billion as regional banking organizations. The Federal Reserve counts holding companies and this list counts banks, so the two counts differ. Assets are the bank's own, not its holding company's consolidated total.
Total assets are taken from Schedule RC, item 12 of the call report (RCFD2170 or RCON2170), and only banks with $10 billion to $100 billion are ranked
The full list of regional banks covers every bank in the band, with combined assets and deposits; categories of banks by asset size sets the band beside the community and large bank tiers.
Which banks are ranked
This list ranks the 9 banks headquartered in California that meet every rule below, using each bank's latest FFIEC call report (data as of September 30, 2026).
- Banks with $10B to under $100B in total assets.
- Charters the regulator has closed, merged or converted are excluded.
- Each bank charter ranks on its own; holding companies are not combined.
What moves total assets
At $10 billion a bank comes under CFPB consumer compliance supervision and the Durbin amendment's cap on debit card fees. At $100 billion the Federal Reserve's enhanced prudential standards begin, with stress testing and liquidity rules. Banks in this range grow mostly by acquiring other banks, and one large deal can move a bank past either line.
