California government, financial and marijuana business leaders met last week in a far-from-resolved debate over whether a state-run bank could be the solution to the cannabis industry’s banking problem. Supporters argued during a Los Angeles gathering of California’s Cannabis Banking Working Group that a public bank would give the state autonomy, serve communities that struggle with bank access and send a message that could shift the nation’s financial paradigm away from Wall Street. Critics insisted a public bank would be too pricey, too risky and do little to overcome banking problems triggered by the conflict between state and federal marijuana laws.
