<\/figure>\n\n\n\nSan Francisco doesn\u2019t require a public bank to subsidize the construction of affordable housing or other worthy objectives.Giselle Garza Lerma\/S.F. Chronicle<\/em><\/a><\/a><\/a><\/a><\/p>\n\n\n\n San Francisco could become one of the first major U.S. cities to create a municipal public bank<\/a> to finance affordable housing, small businesses and green infrastructure.<\/p>\n\n\n\n Last week, the Board of Supervisors voted 9-2 to place a measure on the November ballot that would create a \u201cmunicipal finance corporation\u201d<\/a> as the first step toward launching a public bank.<\/p>\n\n\n\n The logic of the proposal appears compelling: If private banks under provide funds for socially valuable investments, a public entity should step in.<\/p>\n\n\n\n That logic, however, is flawed.<\/p>\n\n\n\n The relevant choice is not between a public bank and the private market, but between creating a bank and using the city\u2019s existing policy tools. When comparing those options, it is clear that San Francisco already has the means to expand investment more transparently and at a lower cost and risk than by establishing a public bank.<\/p>\n\n\n\n Take the case of housing, where supporters argue<\/a> that a public bank could expand affordability by providing developers with cheaper financing. But if the city\u2019s objective is to subsidize housing supply, there is no need to create a public bank to achieve it. <\/p>\n\n\n\n San Francisco already operates a direct and transparent housing subsidy mechanism: the\u00a0Housing Trust Fund<\/a>. The fund was\u00a0established to create, acquire and rehabilitate housing units for low-income and moderate-income families. It\u00a0has procedures<\/a>\u00a0for determining eligibility, evaluating competing proposals, allocating funds and monitoring compliance. The city appropriates\u00a0about $52 million annually<\/a>\u00a0to housing developers, and officials have proposed\u00a0increasing funding to $125 million<\/a>\u00a0\u2014 compelling evidence that San Francisco can expand direct funding for housing without creating a public bank.\u00a0<\/p>\n\n\n\n If the city wishes to make additional investments in affordable housing, why not allocate those funds directly through the Housing Trust Fund? The subsidy would be explicit, appropriated through a normal budget process and delivered through an existing institution.<\/p>\n\n\n\n In contrast, bank subsidies can be opaque, uncertain and volatile. With a bank loan, part of the subsidy is granted upfront through a below-market interest rate. The amount of this subsidy is hard to calculate because it is often unknown what a private lender would charge for a particular project. In addition, given the political nature of housing development, the initial subsidy could expand substantially through loan losses \u2014 making the total subsidy over the lifetime of a project hard to predict, measure and control. As a result, projects that fail to repay can receive large effective subsidies, much larger than intended. <\/p>\n\n\n\n Some city officials no doubt believe that subsidized lending acts as a multiplier that can stretch public dollars further than direct grants. Perhaps so. But even then, San Francisco already possesses a financial tool that is superior to lending through a public bank: housing bonds<\/a>. <\/p>\n\n\n\n Through municipal bonds, affordable housing developers gain access to financing at below-market rates<\/a>. Investors accept lower returns because of tax or other advantages<\/a> associated with the bonds, which translates into lower borrowing costs for developers. Economically, this reduction in borrowing costs represents a subsidy to housing production and serves the same function as a low-interest bank loan. In fact, the city can tailor the bonds to require an identical interest payment as a public bank loan. <\/p>\n\n\n\n San Francisco has\u00a0long relied<\/a>\u00a0on affordable housing bonds to support housing production and preservation. In 2024, voters approved a\u00a0$300 million affordable housing bond<\/a>, and San Francisco has\u00a0issued more than $1.3 billion in bond financing<\/a>\u00a0over the past decade\u00a0\u2014 evidence that the city already has the capacity to expand affordable housing finance at significant scale.\u00a0 <\/p>\n\n\n\n Bond financing offers several advantages. Bond markets rely on private investors to evaluate projects and both price and bear the risk. A public bank, on the other hand, concentrates underwriting decisions in a single institution, and the city or the bank\u2019s depositors will be on the hook if a housing loan goes sour. Studies of public banking indicate that political incentives can weaken underwriting discipline<\/a> and undermine accounting transparency<\/a>. In contrast, bond markets provide repeated price signals based on arm\u2019s-length transactions, so the cost of subsidized finance is easier to observe. The administrative expenses of bond financing are also predictable, whereas public banks may experience higher operating costs<\/a>. <\/p>\n\n\n\n The same logic extends beyond housing. If San Francisco wants to support small businesses or green infrastructure, it already has the tools to provide subsidies and financing without creating a public bank.<\/p>\n\n\n\n About Opinion<\/p>\n\n\n\n Guest opinions in Open Forum and Insight<\/strong> are produced by writers with expertise, personal experience or original insights on a subject of interest to our readers.
