The Massachusetts Senate on Thursday approved three House-passed bills that would tweak state banking and credit union laws, according to State House News Service.

Former Rep. Michael Costello, who co-chaired the Financial Services Committee before his recent resignation to join a law firm, sponsored all three bills.

One bill would modernize the state’s banking laws, in part by eliminating conflicts between state and federal banking laws and providing a certification process for foreign banks seeking to conduct banking business in Massachusetts.

Another bill would provide protections to Federal Home Loan Banks and their insurance company members concerning how their collateral is treated in receivership, and the third bill would authorize branching in the county where a main credit union office is located or at a site within 100 miles of the main office.

Although formal sessions ended on July 31, bills can still move through the House and Senate as long as the few members who attend informal sessions agree.
