Public Banks Keep Local Tax Dollars in Communities

What if your city stopped paying Wall Street to borrow its own money?

TED Fellow Trinity Tran is leading a movement to create public banks, financial institutions owned by local governments instead of private shareholders. Her vision could transform how cities fund schools, roads, and housing while keeping taxpayer dollars working for communities.

Right now, most cities deposit tax revenue into private banks, then borrow money back from those same institutions at interest rates that benefit shareholders. It's like storing your paycheck at a neighbor's house and paying them fees every time you need to access it.

Public banks flip this model. Cities own the bank, earn the interest, and reinvest profits back into local projects. North Dakota has operated the nation's only state-owned bank since 1919, and it's weathered financial crises better than most states.

Tran presented her ideas at TED Fellows Films 2026 in April, explaining how public banks could fund affordable housing, small business loans, and green infrastructure without enriching distant investors. The model has gained momentum as cities search for alternatives to traditional municipal financing.

Several cities are exploring public banking, including Los Angeles, San Francisco, and Philadelphia. These institutions could offer lower interest rates on student loans, support community development, and provide banking services to underserved neighborhoods that private banks often ignore.

The Ripple Effect

When cities control their own financial institutions, the benefits multiply throughout communities. Public banks can prioritize projects that private lenders might reject as unprofitable, like affordable housing in struggling neighborhoods or loans to worker-owned cooperatives.

Local businesses could access capital more easily, knowing their city's bank understands regional economic needs better than national chains. Infrastructure improvements happen faster when cities aren't paying premium interest rates to Wall Street.

North Dakota's century-old experiment proves the concept works long-term. The state's public bank has supported farmers, students, and local governments through recessions and boom times while maintaining financial stability.

Critics worry about government inefficiency, but Tran and other advocates point to existing successful models and strong oversight possibilities. They argue that keeping financial power local strengthens democracy and economic resilience.

Communities are discovering they don't need to choose between fiscal responsibility and local investment when they control their own capital.
