Silicon Valley Bank failed on March 10, 2023, after depositors withdrew $42 billion in a single day

Silicon Valley Bank (SVB) was a mid-sized bank based in Santa Clara, California, that primarily served technology companies, venture capital firms, and their employees. On March 10, 2023, the bank announced it could not cover customer withdrawals and was shut down by federal regulators. The Federal Deposit Insurance Corporation (FDIC) took control of the bank's assets and began the process of returning deposits to customers.

This was the second-largest bank failure in U.S. history, after Washington Mutual in 2008. The speed of the collapse—from announcement to closure in hours—shocked the financial industry because SVB had appeared stable until the day it failed.

Key Takeaways

  • SVB failed because it held too many long-term bonds that lost value when interest rates rose, and it could not sell them fast enough when customers demanded their money back.
  • The bank's customer base was concentrated in tech and venture capital, so when that sector faced funding pressure, many depositors withdrew money at once.
  • Deposits above $250,000 per account were not protected by FDIC insurance, leaving some customers with significant losses until the government stepped in.
  • The FDIC and Federal Reserve created a special program to cover all SVB deposits, regardless of amount, to prevent the failure from spreading to other banks.
  • If you had money in SVB, the FDIC worked to return insured deposits within days, and uninsured deposits were covered under the emergency program.

Why SVB's bond portfolio became a problem

SVB invested heavily in U.S. Treasury bonds and mortgage-backed securities when interest rates were near zero. These bonds paid low rates but were considered safe. When the Federal Reserve began raising interest rates in 2022, the value of those bonds fell sharply—because new bonds now paid higher rates, making the old ones worth less on the open market.

As long as SVB held the bonds until maturity, the losses were only on paper. But in early March 2023, the bank needed cash. It announced it would sell $21 billion of these bonds at a loss to raise money. That announcement triggered panic: if SVB was selling bonds at a loss, customers reasoned, the bank must be in trouble. Depositors rushed to withdraw their money before the bank ran out of cash.

On March 9, 2023, customers withdrew $9.6 billion. On March 10, the bank announced it could not process more withdrawals and regulators shut it down. The bank had roughly $209 billion in deposits but only about $141 billion in assets it could quickly convert to cash.

The concentration of tech industry deposits

SVB was not a typical bank. It did not have millions of small depositors spread across the country. Instead, it served venture capital firms, technology startups, and wealthy individuals in the tech sector. This meant the bank's deposit base was concentrated: a relatively small number of large accounts held a large share of the money.

When the tech industry faced funding pressure in early 2023—venture capital firms were raising less money, and startups were burning through cash—many of SVB's customers needed to withdraw deposits to pay operating costs or return money to investors. Because these customers were all in the same industry and faced similar pressures at the same time, the withdrawals happened together, overwhelming the bank's ability to pay.

A more geographically and industry-diverse bank would have had customers in different situations, so withdrawals would have been spread out over time. SVB's structure made it vulnerable to a sudden shock in a single sector.

FDIC insurance limits and what they covered

The FDIC insures deposits up to $250,000 per depositor, per bank, per account ownership category. This means if you had $250,000 or less in your SVB account, your money was fully protected. If you had more, the amount above $250,000 was at risk.

Many SVB customers—particularly venture capital firms and startup founders—had deposits well above $250,000. Some had tens of millions of dollars in the bank. When SVB failed, these customers faced the prospect of losing everything above the $250,000 threshold.

On March 12, 2023, two days after SVB's closure, the Federal Reserve and FDIC announced an emergency program: they would cover all SVB deposits in full, regardless of amount. This was an extraordinary step, taken to prevent the failure from spreading to other banks. The government reasoned that if uninsured depositors at SVB lost money, they would when ready withdraw funds from other banks perceived as risky, potentially triggering more failures.

How the government responded and what it meant

The Federal Reserve created a new lending program called the Bank Term Funding Program (BTFP). Under this program, banks could borrow money using their bond holdings as collateral, at face value rather than the current market price. This meant a bank holding bonds worth less on the open market could still borrow against their full stated value.

The FDIC, as the receiver of SVB's assets, worked to return deposits to customers. Insured deposits (up to $250,000) were returned within days. Uninsured deposits were covered under the emergency program announced by the Federal Reserve and Treasury Department, so those customers eventually received their full balances as well, though the process took longer.

The government's intervention was designed to stabilize the banking system. Officials believed that if large depositors at SVB lost money, they would lose confidence in other banks and pull their deposits, potentially causing more failures. By guaranteeing all SVB deposits, the government aimed to prevent a broader crisis.

What happened to SVB's assets and remaining operations

The FDIC took control of SVB's assets—the loans, bonds, and other investments the bank held. In March 2023, the FDIC sold most of SVB's assets to First Citizens BancShares, a large regional bank. First Citizens paid $16.5 billion for the assets, which was less than their stated value but more than the FDIC expected to recover.

This sale meant that SVB's customer relationships, branches, and loan portfolio moved to First Citizens. Customers with loans at SVB found themselves banking with First Citizens instead. Depositors' money was returned through the FDIC's process, not transferred to First Citizens as part of a normal acquisition.

The FDIC covered the difference between what it paid out to depositors and what it recovered from the asset sale using its insurance fund, which is financed by fees paid by all banks. This meant the cost of SVB's failure was ultimately spread across the banking system rather than borne by taxpayers directly.

Why this matters for bank account holders

SVB's failure demonstrated that even banks perceived as stable can collapse quickly if they hold the wrong assets and face a sudden withdrawal surge. It also showed that the $250,000 FDIC insurance limit can leave large depositors exposed—though in SVB's case, the government stepped in with an emergency program.

For most account holders with balances under $250,000, SVB's failure had limited direct impact because FDIC insurance protected them. For those with larger balances, the emergency government response meant they ultimately recovered their full deposits, but the process took weeks and created significant uncertainty in the meantime.

The failure also prompted regulators to examine how other banks were managing interest rate risk and deposit concentration. Some banks made changes to their bond portfolios and diversified their customer bases in response.

Frequently Asked Questions

Did I lose money if I had a deposit at SVB?

If your deposit was $250,000 or less, the FDIC insurance protected you and you received your full balance. If you had more than $250,000, you initially faced a loss on the amount above the limit, but the government's emergency program ultimately covered all SVB deposits in full. The process took several weeks.

Why didn't regulators see this coming?

SVB's bond losses were known to regulators, but the bank was not required to sell the bonds when ready. The speed of the deposit withdrawal—$42 billion in two days—was the critical factor. Regulators did not anticipate that the entire tech sector would need cash at the same time, or that news of the bond sale would trigger such a rapid panic.

Could this happen to other banks?

Any bank holding significant amounts of long-term bonds faces similar risks if interest rates rise and deposits leave quickly. After SVB's failure, regulators examined other banks' bond portfolios and deposit bases. Some banks made changes, but the underlying risk—that rising rates reduce bond values—remains a structural feature of banking.

What is the FDIC doing differently now?

The FDIC has increased monitoring of banks' interest rate risk and deposit concentration. Some regulators have proposed raising the insurance limit above $250,000 for certain account types, though this remains debated. The Federal Reserve's Bank Term Funding Program, created in response to SVB, remains available to help banks manage bond portfolio losses.

If I move my money to a different bank, is it safer?

The safety of your deposit depends on the bank's asset quality, deposit mix, and interest rate exposure—not on the bank's size or reputation. Deposits up to $250,000 are protected by FDIC insurance at any bank. If you have more than $250,000, you can spread it across multiple banks or use account ownership categories (like joint accounts or retirement accounts) that each receive separate $250,000 coverage.
