A new bill that aims to give the marijuana industry access to banking services moved forward in the Senate on Wednesday.

The Secure and Fair Enforcement Regulation Banking Act was introduced by a bipartisan group of senators last week. The bill would provide legal protection to banks or other financial institutions that offer services to state-legal marijuana businesses.

The Senate Banking Committee voted 14-9 to advance the measure to the full chamber’s floor.

Sen. Jeff Merkley, an Oregon Democrat and lead sponsor of the bill, called its passage a “historic moment” and an “example of significant bipartisan cooperation.”

“Forcing legal businesses to operate in all-cash is dangerous for our communities; it’s an open invitation to robberies, muggings, money laundering, and organized crime—and the only people benefiting from the current system are criminals,” said Merkley in statement.

“I am committed to building bipartisan momentum to finally get a bill signed into law that ends the cannabis cash economy and improves public safety across the nation,” he added.

The bill is also being led by Steve Daines, R-Mont.; Kyrsten Sinema, I-Ariz.; and Cynthia Lummis, R-Wyo., as well as Majority Leader Chuck Schumer, D-N.Y.

“This legislation will help make our communities and small businesses safer by giving legal cannabis businesses access to traditional financial institutions, including bank accounts and small business loans,” the senators said in a joint statement last week.

“It also prevents federal bank regulators from ordering a bank or credit union to close an account based on reputational risk,” they added.

Even as 39 states have legalized marijuana for recreational or medical use, the sector has struggled to scale. Marijuana’s classification as a Schedule I substance, or one with no currently accepted medical use and a high potential for abuse, along with federal prohibition, pose a risk to banking institutions. This, in turn, has limited access to financing and a broader market.

Moreover, without access to financial services, state-legal cannabis businesses are forced to operate their businesses solely using cash, which can result in robbery, money laundering and organized crime.

Due to the opening of new adult-use markets in individual states, combined U.S. medical and recreational cannabis sales are expected to reach $33.6 billion by the end of 2023, according to analysis from the MJBiz Factbook from industry news outlet MJBizDaily.

The landmark vote Wednesday marked the first time the Senate has considered the legislation. An earlier version of the bill, the SAFE Banking Act, passed in the House seven times previously but has never advanced through the Senate under both Democratic and Republican control. Late last year, lawmakers excluded it from a $1.7 trillion government funding bill.

The bill may face a tougher path to passage if it ends up before the GOP-controlled House.

“I think it probably passes the banking committee, but I think it doesn’t go anywhere in the House,” said Ian Katz, an analyst with Capital Alpha Partners who covers banking and financials.

“Republicans seem to be souring on it,” he added.

The new bill includes stricter requirements for federal regulators, such as prohibiting them from terminating any marijuana-related accounts without “valid reason,” or from denying banking services based on “personal beliefs or political motivations.”
