The Los Angeles City Council is preparing to ask voters if they want to create a publicly owned bank, something no city or state in the United States has done in nearly a century. Council members voted Tuesday to start the process of putting a measure on the Nov. 6 ballot that would allow for the creation of such a bank by amending the city charter. The move is an early step in council President Herb Wessons plan to create a public bank, which he said could offer accounts to scores of city cannabis businesses that are shunned by commercial banks because of federal drug laws. It also could help finance affordable housing, he said. David Jette, legislative director of advocacy group Public Bank L.A., said putting the issue to a citywide vote could be a make-or-break moment for public banking, an idea that has gained steam since the financial crisis and lately seen an influx of support from the cannabis industry. Los Angeles, Oakland, San Francisco and the state of California are all in the process of studying whether they can or should start public banks, in part to serve cannabis businesses. For now, though, the U.S. has just one public bank: the Bank of North Dakota, established in 1919. Were cautiously ecstatic, Jette said after Tuesdays vote. This will be a referendum on the idea of public banking. I think this is an existential vote for our entire national movement.
