Bank of New York Mellon (BNY) has reportedly approached Northern Trust about a potential merger, aiming to combine two major asset-servicing businesses.
The deal, if successful, would create an investment-management giant overseeing more than $3 trillion.
CEOs of both institutions have had discussions, but no specific offer has been made yet.
BNY is considering its next steps, which may include presenting a formal offer to Northern Trust.
However, it is uncertain if the talks will result in a merger.
The Trump administration has shown willingness to approve major bank mergers, which have been uncommon in recent years.
The Federal Deposit Insurance Corp. (FDIC) has proposed rolling back oversight policies for large bank mergers, signaling a potential shift in regulations.
Under the previous rule, mergers involving institutions with assets of $100 billion or more would undergo increased financial stability analysis.
Bankers have been advocating for a relaxation of regulations for merging or establishing new banks.
Recent research indicates that banks offering real-time payments to businesses highlight enhanced payment tracking as a significant benefit.
