Regional banks are financial institutions with total consolidated assets between $10 billion and $100 billion that concentrate their branches and lending across a specific multi-state area rather than operating nationwide.1Federal Reserve Board. Community and Regional Financial Institutions They sit between small community banks and the largest global institutions, with enough scale to handle complex commercial loans that smaller lenders cannot support, and enough local presence to know the industries in their footprint.
How Regional Banks Fit in the Size Ladder
The Federal Reserve draws the line between community banks and regional banks at $10 billion in total consolidated assets. Community banks fall below that threshold; regional banks hold between $10 billion and $100 billion.2Federal Reserve Bank of Cleveland. Resources for Community and Regional Banks Above $100 billion, an institution enters the category of large banking organizations and picks up a separate tier of federal oversight. At the top of the scale, money center banks hold trillions in assets and operate across every major domestic and international market.
Geography is the other defining feature. A regional bank typically concentrates its branches across a handful of neighboring states, such as the Southeast, the Midwest, or the Pacific Northwest, rather than maintaining a presence in every major city. That concentrated footprint lets lending teams build relationships with local businesses and track industry conditions a distant headquarters might overlook.
What Regional Banks Actually Do
Much of a regional bank’s business is built around middle-market companies, meaning firms that generate roughly $10 million to $1 billion in annual revenue. These businesses often need financing that exceeds what a community bank can offer, including syndicated loans, revolving credit facilities, and large equipment financing. Regional banks fill that gap by pairing significant lending capacity with knowledge of local industry conditions in sectors like manufacturing, healthcare, and logistics.
On the retail side, a regional bank collects deposits from local households and uses those funds to support lending. A typical product lineup includes:
- Mortgage originations for home purchases and refinancing
- Home equity lines of credit for borrowing against property value
- Small business loans, including SBA-backed financing
- Commercial real estate financing for office, retail, industrial, and multifamily projects
Many regional banks partner with financial technology companies to offer mobile check deposits, peer-to-peer payments, digital wallets, and online lending platforms, which helps them compete with larger institutions for tech-oriented customers.3Federal Register.

Because regional banks are major commercial real estate lenders, regulators watch their concentration levels. Interagency guidance flags a bank for additional supervisory scrutiny when construction and land development loans reach 100 percent or more of total capital, or when total commercial real estate loans reach 300 percent or more of total capital and the portfolio has grown by 50 percent or more over the prior three years.4Federal Register. Concentrations in Commercial Real Estate Lending, Sound Risk Management Practices Crossing those thresholds does not automatically trigger penalties, but it does invite closer review.
Who Regulates Regional Banks
Three federal agencies share supervisory responsibility. Which one serves as the primary regulator depends on how the bank is chartered.
The Federal Reserve
The Federal Reserve Board supervises bank holding companies, the parent corporations that own regional banking subsidiaries. This authority comes from the Bank Holding Company Act, which lets the Fed issue regulations, set capital requirements, and prevent evasions of the law.5Office of the Law Revision Counsel. 12 USC 1844 – Administration The Fed also examines state-chartered banks that belong to the Federal Reserve System. Under Regulation Y, every bank holding company must serve as a source of financial and managerial strength to its subsidiary banks, so the parent cannot drain resources from its banking units or operate them unsafely.6eCFR. 12 CFR Part 225 – Bank Holding Companies and Change in Bank Control (Regulation Y)
The Office of the Comptroller of the Currency
The OCC charters, regulates, and supervises all national banks and federal savings associations.7OCC. About Us If a regional bank holds a national charter, identifiable by “National” or “N.A.” in its name, the OCC is its primary federal regulator, examining it for safety and soundness and monitoring compliance with federal banking laws.
The Federal Deposit Insurance Corporation
For state-chartered regional banks that are not members of the Federal Reserve System, the FDIC serves as the primary federal regulator. The agency also touches every regional bank because it manages the federal deposit insurance fund, insuring deposits at more than 4,000 financial institutions and directly examining over 2,700 banks and savings associations.8Federal Deposit Insurance Corporation.

Rules That Apply to Regional Banks
Every regional bank must maintain a Common Equity Tier 1 capital ratio of at least 4.5 percent of risk-weighted assets, plus a capital conservation buffer of at least 2.5 percent.9Federal Reserve Board. Annual Large Bank Capital Requirements That brings the effective floor to 7 percent before regulators begin restricting dividend payments and share buybacks. Every bank, regardless of size, also files quarterly Call Reports with its primary federal regulator detailing financial condition, income, and risk exposures.
Not every regional bank faces the same additional requirements. A 2018 law, the Economic Growth, Regulatory Relief, and Consumer Protection Act, raised the asset threshold for mandatory enhanced prudential standards from $50 billion to $250 billion.10Federal Register. Prudential Standards for Large Bank Holding Companies and Savings and Loan Holding Companies The Fed retained discretion to apply enhanced standards to firms with $100 billion or more in assets and used that authority to build a tiered “tailoring” framework:
- Category III covers firms with $250 billion or more in total assets, or $75 billion or more in short-term wholesale funding, nonbank assets, or off-balance-sheet exposure. These banks face full daily liquidity coverage requirements and annual supervisory stress tests.
- Category IV covers firms with $100 billion to $250 billion in total assets that do not meet Category I–III criteria. Liquidity requirements run at roughly 85 percent of the full standard, and supervisory stress tests happen every other year.11Federal Reserve Board. Dodd-Frank Act Stress Test Background
Most regional banks, meaning those in the $10 billion to $100 billion range, fall below these category thresholds entirely. They still meet standard capital requirements and undergo regular examinations, but they are not required to run supervisory stress tests or submit the detailed capital plans that apply to the largest firms.12Federal Reserve Board. Tailoring Rule Visual Firms that do reach Category III or IV also participate in the Federal Reserve’s Comprehensive Capital Analysis and Review process, which tests whether they hold enough capital to keep lending through a severe downturn.13Federal Reserve Board.

What Deposit Insurance Covers at a Regional Bank
The FDIC insures deposits at regional banks up to $250,000 per depositor, per bank, for each ownership category.14FDIC. Understanding Deposit Insurance Ownership categories are counted separately, so a single person could hold a $250,000 individual account and a $250,000 joint account at the same bank with both fully insured. Retirement accounts such as IRAs receive separate coverage.
If a regional bank fails, the FDIC steps in as receiver and works to restore access to insured funds as quickly as possible, often by the next business day.15FDIC. Insured Depository Institution Resolutions Handbook The most common resolution is a purchase-and-assumption transaction, in which a healthy bank acquires the failed bank’s deposit accounts and some of its assets. Depositors in that scenario may barely notice the transition, since accounts simply transfer to the acquiring bank with continuous access to funds. When no acquirer steps forward, the FDIC pays insured depositors directly or transfers insured deposits to a temporary institution, and it may establish a bridge bank that operates for up to two years while a permanent resolution is arranged. Depositors do not need to file a claim for insured funds; the FDIC identifies them from the bank’s records.
Amounts above the $250,000 limit are not guaranteed. Uninsured depositors receive a share of whatever the FDIC recovers by liquidating the failed bank’s remaining assets, a process that can take months or years and rarely returns the full amount.
