NEW YORK–New data reveal just how much larger banks in the U.S. are than credit unions, with the largest U.S. bank’s assets exceeding the assets of all credit unions combined.
The 15 largest consumer banks held a combined total of around $12 trillion in domestic assets as of September 2025, Bankrate reported.
As of Sept. 30, 2025, NCUA data show total credit unions assets in the U.S. were approximately $2.4 trillion.
“That means that a lot of people and businesses are keeping their money with a big bank,” BankRate said. “Most of the biggest banks have been around for a century-plus and many offer wide product variety and in-person banking services at a large branch network.”
The largest credit union in the U.S. and the world, Navy Federal in Vienna, Va., had $197-billion in total assets as of year-end 2025.
Bankrate said the rankings in the chart below are based on the banks’ domestic assets, according to the latest numbers from the Federal Reserve, and do not include investment- or business-only banks on this list.
