When authorities mess-up
In early October, I noted that: Banks are also currently being hit by heavy declines in the value of government bonds, which they use as collateral. These may easily lead to cascading losses on banks, possibly with never-before-seen speed, size, and width.
As we now know, this materialized in the U.S. around six months later, but how did we get into this point?
The global regulatory arm of commercial banks is the Basel Committee on Banking Supervision (BCBS), which operates under the Bank the of International Settlements, or BIS. BIS is often referred as the “central bank of central banks”, as it provides guidance also for central banks.
The deposit ‘binge’
The U.S. deposit base has changed rather drastically during the past three years. This applies especially to easily withdrawable demand deposits, consisting of accounts where money can be withdrawn without advance notice.

What was the reason for this astronomical increase in demand deposits between 2020 and 2022? The combination of Corona lockdowns, stimulus checks and massive monetary stimulus by the Federal Reserve.

Alas, the extremely rapid rise in Treasury yields were catastrophic for banks. For example, the yield of U.S. 2-year Treasure note rose to 20-fold in just two years. This meant that the value of the underlying bond crashed and banks who had acquired Treasuries with near-zero rates (with very high bond prices), suffered heavy losses. These were labelled as “unrealized losses”, because banks obtain Treasuries as held-to-maturity asset. This means that banks hold them to maturity after which the Treasury returns the principal of the bond and pays the interest. Thus, they are not “actual losses” unless the bank is forced the sell Treasuries before they mature, and this is exactly what happened.
The panicky response of authorities
The run of SVB started on Friday 10 March, 2023, and on Sunday the 12th, U.S. authorities concluded that there was a risk of a nationwide bank run. To halt it, they devised an exceptional three-step strategy.
First, there was a joint statement from the Treasury, the Federal Deposit Insurance Corporation (FDIC) and the Fed, announcing that all depositor funds (also uninsured deposits) of the SPV and the Signature Bank were guaranteed. Secondly, the Federal Reserve provided $300 billion worth of liquidity into the system and announced that it will make “additional funds” available to all banks in a Bank Term Funding Program, or BTFP. Thirdly, in a highly exceptional move, President Biden appeared on national television to assure that deposits in the U.S. banks are safe. Such a combination of rapid and exceptional actions basically confirmed that the U.S. was on the verge of a nationwide bank run.
Liquidity and loans
The BTFP became something of ‘deposit guarantee scheme’ with the amount of 1-year loans sought by U.S. banks from the Federal Reserve growing each passing week, with a declining fortunately. The program is scheduled to end by March 11, 2024, but it will almost certainly be extended to unforeseeable future.
There’s a limit concerning the amount loans banks can acquire through the BTFP. Banks need to post a collateral, a liquid asset (Treasury, etc.) in exchange for the loan, which many banks have limited quantity of. Especially smaller banks tend to follow the traditional model of banking, where the inflow of deposits is counterbalanced in their balance sheet by issuing loans.
For example, the First Republic Bank could acquire only $13 billion from the BTFP, because it held mostly loans as assets, while SVB had acquired Treasuries to balance the inflow of deposits. Alas, both strategies led to failures of the banks, which by itself sends a dire warning on the state of the U.S. regional banking system. Essentially, both the traditional model of banking (issuing loans against deposits) and the one pushed by authorities (acquiring Treasuries) have become ‘death traps’ for banks.
Into the collapse?
In May 1984 Continental Illinois National Bank and Trust, a seventh-largest U.S. commercial bank at the time, failed due to bad loans it had acquired from a (failed) Penn Square Bank and a resulting run of 30% of its deposits. Based on the data at the end of Q2, close to 2800 banks (out of the 4642 retail deposit taking banks at the FDIC database), would fail if they would face a similar run on their deposits that toppled Continental Illinois. To note, run on SVB was 87%, Silvergate 52% and Signature Bank 29% of their deposits.
And, the issue is pressing. For example, the loan portfolio of First Republic Bank consisted 80% of real estate loans. It took losses from its loan portfolio, and had a very limited liquidity buffer to counter the deposit outflow, and failed. There are hundreds of U.S. banks with a higher share of real estate loans in their loan portfolio than what First Republic had. Moreover, thousands of U.S. banks could not cope with the deposit run faced by Continental Illinois.
