March 2023 marked a dramatic moment in global finance with the collapse of Silicon Valley Bank, Signature Bank, and Silvergate Capital, some of the most prominent banks in the United States. While Silicon Valley Bank and Signature Bank dominated headlines, many other major banks have collapsed quietly over the past two decades.
The failure of Silicon Valley Bank alone impacted approximately $175 billion in deposits and $209 billion in assets, making it the second-largest bank failure in US history. These events raised renewed concerns about why banks collapse and how frequently such failures have occurred in modern times.
Financial risk cycles, banking regulation, and systemic exposure — topics often explored in Melbur’s finance content — help explain why these collapses are not isolated incidents. Let’s examine the largest bank failures of this millennium and the conditions that led to them.
A Pattern of Financial Contagion
Historically, major bank collapses tend to occur in clusters. The most notable example before 2023 was the 2007–2008 global financial crisis, when subprime mortgage losses triggered widespread failures. During that period, both traditional banks and so-called “shadow banks” — institutions that perform bank-like functions without the same regulatory oversight — collapsed in large numbers.
These institutions held foreclosed mortgages as collateral, but declining housing prices made asset valuation nearly impossible. The resulting credit freeze led to hundreds of bank shutdowns. According to the Federal Deposit Insurance Corporation (FDIC), more than 550 banks have failed since 2001.
In 2023, Silicon Valley Bank followed a different but equally dangerous path: heavy investment in long-term US Treasuries and mortgage-backed securities. When the Federal Reserve raised interest rates sharply in 2022 to combat inflation, the value of those securities fell. Combined with poor liquidity management, this led to insolvency once depositors began withdrawing funds.
The Biggest Bank Failures Since 2000
1. Washington Mutual Bank
Deposits: ~$188 billion
Assets: ~$307 billion
Date of Failure: September 25, 2008
This remains the largest bank failure in US history. During the 2008 financial crisis, customers withdrew nearly $17 billion in less than 10 days. Washington Mutual received no government bailout and was seized by regulators, then sold to JPMorgan Chase for $1.9 billion, sparing the FDIC from losses.
2. Silicon Valley Bank
Deposits: ~$175.4 billion
Assets: ~$209 billion
Date of Failure: March 10, 2023
SVB collapsed following a rapid bank run triggered by losses on long-term securities and panic among depositors. Given the scale of the failure, President Joe Biden reassured customers that their deposits were safe. The US government guaranteed all deposits, though the bank itself was not bailed out. Deposits were transferred to the National Bank of Santa Clara under FDIC control.
3. Signature Bank
Deposits: ~$88.6 billion
Assets: ~$110.4 billion
Date of Failure: March 12, 2023
Signature Bank collapsed just days after SVB due to contagion fears. It was closed by New York regulators and later sold to New York Community Bancorp, to be absorbed by its Flagstar Bank subsidiary. Depositors were protected, but shareholders and unsecured creditors were not.
4. Colonial Bank
Deposits: ~$20 billion
Assets: ~$25 billion
Date of Failure: August 14, 2009
Colonial Bank expanded rapidly through heavy exposure to Florida’s real estate market. When defaults surged, losses became unmanageable. A $2.9 billion fraud scheme involving senior executives further accelerated the collapse.
5. IndyMac Bank
Deposits: ~$19.1 billion
Assets: ~$32 billion
Date of Failure: July 2008
IndyMac was a major mortgage lender that failed when home prices collapsed and secondary mortgage markets froze. A public warning from Senator Chuck Schumer intensified depositor panic, resulting in massive withdrawals. IndyMac filed for Chapter 7 bankruptcy shortly thereafter.
6. Guaranty Bank
Deposits: ~$12 billion
Assets: ~$13 billion
Date of Failure: August 21, 2009
Operating mainly in Texas and California, Guaranty Bank suffered heavy losses due to falling real estate prices. Foreclosures failed to recover loan balances, leading to insolvency.
7. Downey Savings and Loan
Deposits: ~$9.7 billion
Assets: ~$12.8 billion
Date of Failure: November 2008
Downey Savings collapsed after heavy exposure to risky adjustable-rate mortgages. Regulators seized the bank and sold it to U.S. Bank, marking the largest bank failure in Orange County history.
8. BankUnited FSB
Deposits: ~$8.6 billion
Assets: ~$12.8 billion
Date of Failure: May 21, 2009
BankUnited, a major Florida-based bank, collapsed under the weight of mortgage losses. Its assets were sold to a private investment group at a significant cost to the government.
9. AmTrust Bank
Deposits: ~$8 billion
Assets: ~$12 billion
Date of Failure: December 4, 2009
AmTrust failed due to high exposure to risky mortgage markets. About 75% of its assets were sold to New York Community Bank, with the FDIC absorbing roughly $2 billion in losses.
10. Corus Bank
Deposits: ~$7 billion
Assets: ~$7 billion
Date of Failure: September 11, 2009
Corus Bank collapsed due to bad commercial real estate and condominium loans. Its deposits were transferred to MB Financial, ensuring continuity for customers.
Final Thoughts
Bank failures are rarely random. They usually emerge during periods of economic stress, rising interest rates, or asset bubbles. The collapses of the past two decades reinforce the importance of diversification, prudent risk management, and strong regulation.
For businesses and individuals alike — themes often addressed on Melbur and Melbur UK — understanding these historical failures helps in making better financial decisions and avoiding overexposure to systemic risks.
