Three failures, one confidence shock
The U.S. banking upheaval of 2023 was neither one identical failure repeated three times nor simply a replay of 2008. Silicon Valley Bank, Signature Bank and First Republic Bank served different customers and held different assets. What connected them was the interaction of concentrated funding, interest-rate exposure, confidence and the speed at which deposits could leave. Their failures also exposed shortcomings in management and supervision that had developed before the decisive withdrawals. [1][4][6]
California closed Silicon Valley Bank on March 10; New York closed Signature on March 12; California closed First Republic on May 1. The FDIC became receiver in each case. But the government’s protection of depositors, the arrangements for selling assets and the consequences for investors were not interchangeable. Understanding the episode means separating the operating bank from its shareholders and separating emergency from the economic value of the business. [8][9][10]
Why an uninsured deposit can behave differently
A bank deposit is both a customer’s money and a bank’s funding liability. Many business and affluent-client balances exceed ordinary deposit-insurance coverage. When confidence weakens, those customers have a reason to move first rather than wait to discover the size or timing of a receivership recovery. A large balance can leave in a single electronic instruction; counting accounts therefore says little about the dollars at risk.
Concentration makes that problem more acute. Customers linked by the same industry, investors or advisers can need cash at the same time and respond to the same news. GAO’s preliminary review identified risky business strategies and inadequate risk management at SVB and Signature. The relevant distinction is not that uninsured money always runs. It is that past stability can be a poor guide when many customers simultaneously reassess the same institution. [5]
SVB: the technology boom filled the balance sheet
SVB’s funding grew alongside venture-backed technology and life-sciences businesses. Fundraising and other events put cash into client accounts; the bank invested substantial balances in longer-dated securities. When venture activity slowed and customers spent their cash, the earlier deposit inflow reversed. Rising rates simultaneously reduced the market value of fixed-rate assets. The Federal Reserve’s review described this connection between the customers’ financing cycle and the bank’s balance sheet. [2]
The securities’ low credit risk did not make them low-risk funding assets. Agency mortgage-backed securities can repay over long periods, while depositors can ask for cash now. As rates rise and refinancing slows, mortgage cash flows can also remain outstanding longer. SVB thus faced pressure on both sides: deposits became less dependable just when selling older, low-yield securities became more expensive. This was a maturity and interest-rate problem, rather than a story requiring widespread defaults by the underlying borrowers. [2][3]
The sale, the capital plan and the run
On March 8, SVB announced a balance-sheet restructuring involving securities sales and a proposed capital raise. The Federal Reserve’s review records more than $40 billion of deposit outflows on March 9 and management’s expectation of another $100 billion the following day. Those are different quantities: the second was an expected outflow, not a completed withdrawal before closure. California closed the bank on March 10. [1]
The Fed found that management had failed internal tests, lacked workable contingency funding preparations and altered assumptions rather than resolving underlying weaknesses. It also found that interest-rate management emphasized near-term earnings and protection against falling rates, including removal of hedges. The review criticized both board oversight and the supervisors’ failure to secure timely correction. These findings explain why “rates rose” is incomplete: the rate shock met a particular set of asset choices, funding assumptions and operational limitations. [1][3]
Accounting did not create cash
Available-for-sale, or AFS, securities generally reflect fair-value changes through accumulated other comprehensive income, or AOCI, within accounting equity. Held-to-maturity, or HTM, securities generally remain at amortized cost when the required intent and ability to hold are present. The economic value of an HTM security still changes with rates even when that change does not pass through its balance-sheet carrying amount. Regulatory capital treatment is a separate layer: SVB could exclude AOCI from regulatory capital under the applicable framework. [2][7]
An unrealized loss is therefore not automatically an immediate cash loss, a regulatory-capital breach or proof of legal insolvency. Conversely, a satisfactory reported capital ratio does not ensure enough cash to meet a run. Selling an asset can crystallize a loss; borrowing against it can avoid that sale but creates an obligation, requires eligible collateral and may carry a higher funding cost. The issue is whether a bank can finance its assets long enough for their cash flows to arrive, at a cost its earnings can support.
Signature: concentrated funding and weak preparedness
Signature was not simply another SVB securities portfolio. Its commercial-bank franchise included real-estate and business lending as well as a digital-asset-related deposit business. The FDIC’s account reported that about 90% of its year-end 2022 deposits were uninsured. Digital-asset customers were one concentration within that funding structure; reducing the entire bank to a cryptocurrency label obscures the broader commercial deposit base. [4][8]
The FDIC’s internal review attributed the failure to management’s rapid growth without adequate governance, controls and -risk management. It also criticized the agency’s delayed escalation, untimely examination work and staffing constraints. As confidence deteriorated after SVB, Signature could not meet the withdrawal stress. Those findings do not establish that a single asset class, social-media message or political motive caused the closure. They describe a vulnerable bank that could not execute an adequate liquidity response when confidence failed. [4][23]
The subsequent sale also had boundaries. Flagstar acquired substantially all deposits and certain loan portfolios of Signature’s bridge bank, but deposits associated with the digital-asset banking business were excluded from that transfer. Their treatment was part of the FDIC’s resolution, not evidence that every Signature customer became a Flagstar customer. [8]
First Republic: strong relationships did not fix repricing
First Republic’s franchise relied on wealthy households, personalized service and competitively priced lending, including long-dated residential mortgages. Its problem was not primarily a sudden wave of borrower defaults. The FDIC review describes low-yielding, longer-term assets funded by deposits that could leave or demand higher rates. It also found that confidence in customer loyalty and historical deposit stability underestimated the risk of a run. [6]
At year-end 2022 the bank reported $176.4 billion in deposits, including $119.5 billion uninsured, approximately 68%. By March 31, deposits were $104.5 billion, including $30 billion placed by eleven large banks on March 16. Subtracting that support leaves $74.5 billion; compared with year-end, that is a $101.9 billion reduction. This arithmetic describes changes in reported balances, not a claim that every dollar moved on one day. The FDIC’s review called the earlier strong rating too generous. [6]
First Republic initially met withdrawals with replacement funding, but the repricing changed the economics. A mortgage originated at a low fixed rate does not suddenly earn more because the bank’s borrowing cost rises. Selling discounted assets can impair capital; retaining them with expensive funding can impair future earnings. The FDIC’s May testimony identified this mismatch as a constraint on restructuring, asset sales and raising capital. The extra weeks of survival did not demonstrate that the underlying business model had recovered. [11]
A liquidity line is not the same as usable cash
The Federal Home Loan Banks were important lenders during the stress. GAO reports that SVB’s outstanding advances rose from $20 billion on March 1 to $30 billion at failure; Signature’s rose from $8.2 billion to $11.2 billion. First Republic’s increased from $19.4 billion on March 1 to $28.1 billion by its May 1 failure. These were secured borrowings, not new equity. [12]
The operational distinction matters. A theoretical borrowing capacity must become eligible, documented and transferable collateral before it becomes spendable . Existing liens can complicate movement between lenders. GAO found that the FHLBanks used coordination arrangements to help Signature and First Republic access funding, while SVB failed before the San Francisco FHLBank could complete comparable coordination. Borrowing can bridge a timing problem. It cannot by itself replace lost franchise value or make an uneconomic funding structure profitable. [12]
What the emergency response protected
On March 12, Treasury, the Fed and the FDIC announced systemic-risk exceptions for the resolutions of SVB and Signature. These protected all depositors at those institutions, including uninsured balances. The announcement expressly excluded shareholders and certain unsecured creditors from protection and provided for recovering deposit-insurance losses attributable to uninsured-depositor protection through a special assessment on banks. It was not a permanent blanket guarantee of every deposit at every U.S. bank. [9]
The Fed separately created the Bank Term Funding Program, offering eligible institutions loans of up to one year against qualifying securities valued at par for this purpose. That collateral convention reduced the need to sell depressed securities immediately; it did not rewrite their market prices or turn the loan into capital. New lending ended on March 11, 2024. First Republic’s May resolution used a different route: JPMorgan assumed all its deposits through an FDIC transaction determined to meet the least-cost requirement, with OCC approval of the acquiring national bank’s application. [10][13][14][15]
Loss estimates have dates and different meanings
The cost of a failed bank is not its total assets, the amount of deposits transferred or the face value of emergency loans. Receivership recoveries, asset-sale proceeds, expenses and legal outcomes affect the Deposit Insurance Fund’s eventual result. The portion attributed to protecting uninsured depositors under the systemic-risk exceptions is also distinct from the overall cost of the failures.
The FDIC’s assessment page, updated April 17, 2026 and checked for this article on October 4, reports approximately $16.7 billion as the estimated amount attributable to the SVB and Signature systemic-risk action. It records March 30, 2026 as the eighth quarterly payment date, with that quarter’s rate reduced to 2.97 . The page provides for possible offsets or a final shortfall assessment as litigation and receiverships are resolved. Accordingly, the end of quarterly collections is not proof of a final realized loss, and $16.7 billion is not the combined final cost of all three banks. [16]
Credit Suisse and Silvergate belong in separate columns
Credit Suisse’s March crisis had an international confidence connection but a different institutional history and legal outcome. FINMA’s review describes cumulative failures of strategy and management, scandals and damaged confidence. Swiss authorities supported the UBS takeover announced on March 19 with substantial central-bank assistance. This was a Swiss emergency acquisition involving a global banking group, not an FDIC receivership or an application of the U.S. systemic-risk exception. [17][18]
Silvergate is another necessary distinction. On March 8, its holding company announced an intention to wind down and voluntarily liquidate Silvergate Bank, with a plan that included full repayment of deposits. That announcement is evidence of the company’s plan at the time, not a contemporaneous certification that every payment had been completed. A voluntary bank liquidation should not be counted as the same legal event as the state closures and FDIC receiverships of SVB, Signature and First Republic. [19]
The durable lesson is the interaction
The Fed’s review linked SVB’s weaknesses to regulatory tailoring, long transition periods and insufficiently forceful supervision, while acknowledging that stronger requirements might not necessarily have prevented failure. GAO subsequently emphasized the need for more timely escalation and the limitations of intervention frameworks tied to capital measures that can lag other signs of trouble. These are institutional findings, not a claim that one rule change alone explains every failure. [7][20]
Later evidence sharpens the chronology. An FDIC staff study published in May 2026 found exceptionally rapid withdrawals across the three banks, including continued outflows at the bridge banks after the original institutions failed. Its measurement windows therefore should not be confused with withdrawals before closure. The broader conclusion remains an interaction: rate exposure weakened economic flexibility, concentrated deposits accelerated funding pressure, execution limits restricted available responses, and delayed correction allowed vulnerabilities to accumulate. Each bank reached that intersection through a different business model. [21][22]
