U.S. Rep. Michael Capuano recently introduced a bill that would require “too big to fail” financial institutions to beef up their capital to the same level as the government subsidy they receive.

Capuano, a Democrat representing Massachusetts’ 7th District, originally filed the legislation, today titled “The Subsidy Reserve Act of 2015,” in 2013.

In a statement issued last Friday, Capuano’s office pointed out that the Federal Reserve just last year had rebuked the 11 largest banks in the country, finding fault with their so-called “living will” plans. Capuano’s legislation would apply to financial institutions with assets totaling more than $500 billion and would require those “too big to fail” banks to maintain capital equal to the amount of taxpayer subsidy they get.

“The choice would be up to each institution and their shareholders – stay big while protecting taxpayers or shrink your institution and access those funds, you cannot do both,” Capuano said in a statement.

The bill has been referred to the Financial Services Committee.
