The U.S. Top Banks by Uninsured Deposits
Today, there is at least $7 trillion in uninsured bank deposits in America.
This dollar value is roughly three times that of Apple’s market capitalization, or about equal to 30% of U.S. GDP. Uninsured deposits are ones that exceed the $250,000 limit insured by the Federal Deposit Insurance Corporation (FDIC), which was actually increased from $100,000 after the Global Financial Crisis. They account for roughly 40% of all bank deposits.
In the wake of the Silicon Valley Bank (SVB) fallout, we look at the 30 U.S. banks with the highest percentage of uninsured deposits, using data from S&P Global.
Which Banks Have the Most Uninsured Deposits?
Over the last month, SVB and Signature Bank went under at lightning speed.
Below, we show how their level of uninsured deposits compare to other banks. The dataset includes U.S. banks with at least $50 billion in assets at the end of 2022.

Bank of New York (BNY) Mellon and State Street Bank are the active banks with the highest levels of uninsured deposits. They are the two largest custodian banks in the U.S., followed by JP Morgan. Custodian banks provide critical infrastructure in the financial system, holding assets for safe-keeping for investment managers and transferring assets, among other duties.
Both BNY Mellon and State Street are considered “systemically important” banks.
Where these banks differ from SVB is that their loans and held-to-maturity securities as a percentage of total deposits are much lower. While these loans made up over 94% of SVB’s deposits, they made up 31% of BNY Mellon’s and 40% of State Street Bank’s deposits, respectively.
Held-to-maturity securities pose a greater risk to banks. Many of these holdings have lost value since interest rates have risen at a sharp clip. This presents interest-rate risks to banks. Consider how the value of long-term U.S. Treasurys declined about 30% in 2022. In this way, if a bank sells these assets before they mature, they take on a steep loss.
Overall, 11 banks on this list have loans and held-to-maturity assets that are over 90% of their total value of deposits.
To prevent wider ramifications, regulators implemented emergency actions. This was done by protecting all deposits of SVB and Signature Bank days after they announced failure.
The Fed also set up an emergency lending facility for banks. This Bank Term Funding Program (BTFP) was created to provide additional funding for banks if depositors pulled their money. It was also set up to prevent banks from interest-rate risk.
So far, more than $50 billion in loans have been withdrawn from the BTFP, up from $11.9 billion in its first week. (The Federal Reserve updates these numbers on a weekly basis.) This has led the Fed’s balance sheet to once again tick higher after slowly declining with the introduction of quantitative tightening in 2022.
Between a Rock and a Hard Place
What does this mean for the U.S. banking system, and what are the implications for depositors and the broader financial system?
On the one hand, the Fed may have had no other option than to save the banks.
“The way the world is, the government had no alternative but to back all deposits. Or we would have had the biggest goddamn bunch of bank runs you ever saw.”
The bigger problem is that it introduces new risk into the system. If market participants expect the Fed to always come to the rescue, they will likely make less prudent decisions. Beyond this, the ultra-low interest rate environment not only made banks more sensitive to interest-rate risk as rates went up, but it also lowered the cost of risk-taking.
Now, the Fed has said that they could take necessary actions to protect uninsured deposits. How quickly BTFP loans increase in the next few months will be anyone’s guess as clients from smaller banks withdraw funds and send to larger ones or invest in money market funds.
Editor’s note: Not all types of uninsured deposits are created equal. For custodian banks, retail deposits can make up a smaller portion of total deposits while operational deposits comprise a larger share. These types of deposits hold large amounts of funds for other banks for the purposes of custody or clearing and cash management, among other functions. For this reason, they are often considered more stable forms of deposits.
