Merrill Edge Inside the Checking AccountNarrow moat

Bank of America (BAC) — moat facet

Bank of America's 38.7 million checking accounts are a pipeline into Merrill that a standalone broker cannot build.

Bank of America's wealth business is connected to its deposit franchise in a way a standalone broker cannot copy. Consumer Banking offers investment accounts and products alongside checking and savings1, largely through Merrill Edge. Consumer investment assets were $599.1 billion at the end of 2025 and $639.5 billion in June 20262.

Up about 7% in six months.

That is a pipeline. A customer who opens a checking account, sees investment options in the same app and builds savings over years can move up to Merrill's advisory business once they pass $250,0003. The bank reported 50 million active digital banking users in the second quarter of 20264, each one a potential investor.

The consumer bank is also where the bank's digital assistant lives: Erica had 24.6 million active users, up 23%5.

The numbers are consistent with the pipeline working: consumer investment assets rose about 6.7% in six months6.

The digital franchise feeds it. Seventy percent of the bank's total sales were digitally enabled in the second quarter of 20267, and an investment account opened in the same app as a checking account costs the bank little to win.

Consumer investment assets are reported each quarter. Growth faster than the market's would confirm the pipeline is working; growth slower than markets would say the customers were investing somewhere else.

⚠ Threats to the moat
⚠ THREAT 01
The Price Paid on Uninvested Cash
Part of Merrill's income is the spread on clients' idle cash, and regulators have already made Bank of America settle over it.
