The U.S. Senate Committee on Banking, Housing and Urban Affairs’ ranking member, Senator Elizabeth Warren, sent a letter to Bank of New York Mellon (BNY Mellon) CEO Robin Vince warning that reported discussions about acquiring Northern Trust could be “presumptively illegal” under federal antitrust law and could increase financial stability risks. The letter highlights both firms’ role as major providers of asset custody and administration services and states that a combined entity’s estimated custodial services market share would exceed 30 percent, with market concentration (as measured by the Herfindahl-Hirschman Index) rising by roughly 400 points. It also argues the deal would heighten systemic risk by combining one “Too-Big-To-Fail” bank with a “borderline” Too-Big-To-Fail bank, and references prior enforcement actions against BNY, including a USD 5 million Commodity Futures Trading Commission fine in August 2024 for inaccurate reporting of at least 5 million swap transactions from 2018 to 2023 and Securities and Exchange Commission charges the same month related to off-channel communications. Warren requested that BNY Mellon brief the committee on the potential merger.
