A public bank is a financial institution owned by a government entity instead of private shareholders, created by legislation to hold public deposits and lend them back into the local economy. It doesn’t serve retail customers the way your neighborhood branch does. It holds the government’s own money, partners with community banks to expand their lending capacity, and returns its profits to the public treasury rather than to investors. The Bank of North Dakota, founded in 1919, is still the only state-owned general-service bank operating in the United States, and it carries roughly $6.2 billion in loans.
How a Public Bank Differs From a Commercial Bank
The ownership structure changes everything downstream. A commercial bank answers to shareholders who expect a return on their investment, so its lending decisions are filtered through profitability. A public bank’s sole owner is a government entity, which means its priorities are set by statute and political accountability rather than quarterly earnings.
That shift in ownership lets a public bank accept lower returns on loans that advance a policy goal, such as affordable housing, small business lending in underserved areas, or agricultural credit during a downturn. Private banks walk away from those deals because the risk-adjusted return doesn’t satisfy shareholders. A public bank has no shareholders to satisfy.
Public banks also generally do not compete with commercial banks for retail customers. They don’t issue consumer checking accounts, credit cards, or ATM networks. They operate as wholesale institutions behind the scenes of the consumer-facing financial system.
How a Public Bank Is Structured
A public bank is created through specific enabling legislation that defines its ownership, mission, and governance. North Dakota’s statute declares that the state “shall engage in the business of banking” and maintain a system “owned, controlled, and operated by it, under the name of the Bank of North Dakota.”1North Dakota Legislative Branch. North Dakota Century Code Title 6 Chapter 09 That kind of explicit legislative mandate is what separates a public bank from a government-backed lending program or development authority.
Governance runs through a politically accountable oversight body rather than a private board. The Bank of North Dakota is overseen by the three-member Industrial Commission, made up of the Governor, the Attorney General, and the Agriculture Commissioner.2Bank of North Dakota. BND Leadership The people running the bank answer to voters, which also means the bank’s strategic direction can shift with elections.
Newer frameworks impose tighter constraints. California’s Assembly Bill 857 requires any local government to complete a viability study before applying for a charter, limits the state banking commissioner to issuing no more than two public bank licenses per calendar year, and caps the total number of authorized public banks at ten.3California Legislative Information. California Assembly Bill 857 The law defines a public bank as a nonprofit corporation wholly owned by a local agency or joint powers authority, a narrower structure than North Dakota’s state-owned model.
What a Public Bank Actually Does
The foundation of a public bank’s operations is its role as the government’s official depository. North Dakota law requires all state funds, including those of state educational and industrial institutions, to be deposited in the Bank of North Dakota.1North Dakota Legislative Branch. North Dakota Century Code Title 6 Chapter 09 That captive deposit base gives the bank a large, stable pool of capital without needing to attract retail customers or pay competitive rates to depositors.
Lending is where the mission becomes concrete. Rather than originating consumer loans, a public bank typically participates in loans originated by local community banks and credit unions. A small-town bank that lacks the capital to fund a large agricultural loan on its own can partner with the public bank, which buys a share of the loan and assumes part of the risk. The community bank keeps the customer relationship. The public bank adds capacity. Lending decisions stay local.
Direct lending happens too, but in narrow lanes tied to specific programs. The Bank of North Dakota originates student loans through its DEAL Student Loan program and runs specialized lending for career training.4Bank of North Dakota. DEAL Student Loan Infrastructure financing is another common application. When a municipality needs to build a water treatment plant or expand a road, a public bank can lend at lower cost than the bond market, reducing the interest burden on taxpayers.
How a Public Bank Is Funded
Primary funding comes from the government deposits the bank holds by law. Because those deposits are mandatory rather than voluntary, the bank doesn’t face the liquidity risks commercial banks manage when depositors chase better rates. That stability lets it make longer-term lending commitments.
Profits flow back to the government owner. The Bank of North Dakota has transferred hundreds of millions of dollars to the state’s general fund over its century of operation, effectively turning government deposits into a revenue-generating asset for taxpayers. The bank retains a portion of earnings to maintain adequate capitalization.
If additional capital is ever needed beyond retained earnings, the government owner can appropriate funds or back the bank with the state’s full faith and credit. The bank’s solvency ultimately rests on the government’s taxing authority rather than on its ability to raise private capital.
How Deposits Are Protected
The Bank of North Dakota is not a member of the FDIC. North Dakota Century Code Section 6-09-10 provides that all BND deposits are guaranteed by the full faith and credit of the State of North Dakota.5Bank of North Dakota. BND Operations The state’s general fund and taxing authority stand behind the deposits instead of the federal insurance fund.
That arrangement works because BND’s depositors are government entities, not individual consumers. FDIC coverage insures individual accounts up to $250,000, which matters enormously for personal savings but is a drop in the bucket for government accounts holding tens of millions.6Federal Deposit Insurance Corporation. Deposit Insurance for Accounts Held by Government Depositors A state guarantee backed by taxing authority can provide more comprehensive protection for those large balances.
Newer legislation handles this differently. California’s AB 857 requires public banks to obtain deposit insurance approved by the state banking commissioner, which can be FDIC insurance, private share insurance, or self-insurance where deposits are guaranteed by the bank’s government owners.3California Legislative Information. California Assembly Bill 857 If you are an individual consumer, none of this is relevant to you directly; a public bank is not where you keep a checking account.
Counter-Cyclical Lending
The function that private banks genuinely cannot replicate shows up during a crisis. When private credit markets seize, commercial banks pull back lending precisely when businesses and individuals need credit most. A public bank can move in the opposite direction. During the agricultural credit crisis of the 1980s, the Bank of North Dakota aggressively backstopped local bank loans and extended credit to farmers who couldn’t get it elsewhere. It played a similar stabilizing role during the 2008 financial crisis, maintaining credit availability while private lenders retreated. Private banks have no incentive to lend into a collapsing market. Public banks were arguably built for it.
The Bank of North Dakota and the Movement to Replicate It
BND remains the only operating state-owned general-service bank in the country, which makes it both the proof of concept and the cautionary tale for public banking. More than a century after its founding, it holds over $6.1 billion in loans and continues to generate consistent profits that flow back to state coffers.7Bank of North Dakota. BND Call Report June 2025 Critics point out that North Dakota’s small, relatively homogeneous population, resource-driven economy, and consistent political support since 1919 make the model difficult to replicate.
Legislation has gained traction elsewhere. California’s AB 857 created a legal framework for local public banks in 2019. New York has introduced bills for both municipal and state-level public banks. Massachusetts, New Mexico, Oregon, Washington, New Hampshire, and Arizona have advanced public banking legislation since 2023, with Arizona’s 2024 bill proposing a “Sovereign State Bank of Arizona” modeled directly on BND. None of those efforts has yet produced an operating bank. The path from legislation to lending involves viability studies, chartering, deposit protection arrangements, hiring experienced bankers, and securing access to the Federal Reserve’s payment system, and recent litigation has confirmed that Federal Reserve Banks retain broad discretion over master account applications.
Criticisms and Risks
Political interference tops most lists of concerns. When elected officials or their appointees control a bank, lending decisions can be influenced by political considerations rather than sound underwriting. Research on government-owned banks internationally has found that political turnover in bank leadership correlates with deteriorating financial performance, with the effect more pronounced in developing countries than developed ones.
Taxpayer exposure is another legitimate concern. Because deposits are guaranteed by the government’s full faith and credit rather than a separate insurance fund, a catastrophic failure falls directly on taxpayers. Economists describe this as a “soft budgetary constraint”: the government owner can inject capital to keep the bank afloat in ways that would not happen with a private institution. That’s a feature during a crisis and a moral hazard in normal times.
Competing institutional goals create their own tension. A private bank has one clear objective: profitability. A public bank juggles economic development, affordable lending, counter-cyclical support, and revenue for the state treasury. Those goals pull against each other. Maximizing transfers to the general fund directly competes with offering the lowest possible interest rates to borrowers. Managing that tension requires disciplined governance over decades, and not every political environment delivers it.
There’s also a market distortion argument. A government-backed institution lending at below-market rates could crowd out private lenders or push them toward riskier loans to compete. BND has largely avoided this by operating as a wholesale partner rather than a retail competitor, but that restraint is a choice its leadership has made, not a feature the model enforces on its own.
