On the same day that Canada became the first G-20 country to legalize the sale of marijuana for recreational use, Comptroller Otting indicated that a legislative remedy would ultimately help US banks interested in serving the growing legal cannabis market to navigate through the current haze of conflicting state and federal laws. At an October 17 speaking event in Washington, DC, as reported by Politico, Otting said he was "hopeful there's enough momentum in that direction," though he did not share any specific recommendations. Otting told reporters that it's "so complex for banks right now to be able to bank marijuana," given the federal prohibition that requires banks to file suspicious activity reports on their customers, adding that forcing businesses in the emerging sector to deal strictly in cash is "generally not healthy." Meanwhile, the ABA earlier this month launched a survey of its members seeking input on difficulties arising from the contradictions between marijuana's legalization in a growing number of states and its continuing federally prohibited status. The organization and its affiliated state bankers associations will use the responses "to help illustrate to regulators and legislators the need for greater clarity."
