In its annual report filed with the SEC on February 24, 2023, SVB Financial Group reported a common equity tier 1 capital ratio of 12.05% at December 31, 2022. Its total capital ratio was 16.18%. The filing also classified Silicon Valley Bank, its banking subsidiary, as well capitalized under regulatory guidelines.
The same filing disclosed approximately $15.2 billion of unrealized losses on held-to-maturity securities. Those losses did not reduce the reported regulatory capital ratios. Both disclosures could be correct because the capital calculation did not require those bonds to be marked to market.
What did the bonds actually show?
The 2022 Form 10-K’s investment-securities note reported held-to-maturity securities with an amortized cost of $91.321 billion at December 31, 2022. Their disclosed fair value was $76.169 billion.
The subtraction is $15.152 billion. That was the net gap between the portfolio’s accounting value and its disclosed fair value, not an estimate constructed after the bank failed.
For scale, the consolidated balance sheet reported approximately $16.3 billion of total equity at the same date. The bond valuation gap approached that entire amount.
That comparison establishes size, not a replacement capital ratio. The fair-value gap was pretax, while consolidated equity included capital interests that are not interchangeable with common equity tier 1 capital. An adjusted regulatory ratio would also require the applicable tax treatment, deductions and denominator. Simply subtracting $15.152 billion from total equity would not produce it.
The central fact needs no such reconstruction. SVB’s own securities note disclosed an economically substantial loss of market value beside a balance sheet that retained those securities at amortized cost.
Why did accounting leave the loss out?
SVB’s accounting policy distinguished available-for-sale securities from held-to-maturity securities. Available-for-sale securities were recorded at fair value. Their unrealized valuation changes generally passed through accumulated other comprehensive income, a component of equity, rather than current earnings.
Held-to-maturity securities received different treatment. SVB carried them at amortized cost because it classified them as securities it intended and was able to hold until maturity.
The FDIC’s examination manual describes that same distinction. Held-to-maturity classification depends on positive intent and ability to hold the securities, not on their market prices remaining close to purchase prices.
Consequently, a decline in fair value did not automatically become an expense or a reduction in recorded equity. Credit-loss accounting remained relevant, but a market-price decline caused by interest rates was not itself the same thing as an expected failure to collect contractual payments.
The classification therefore mattered twice. It determined the number on the balance sheet and prevented the disclosed market-value shortfall from flowing automatically into the equity that underpinned regulatory capital.
What did the capital ratios measure?
The regulatory-capital disclosure reported SVB Financial Group’s December 31, 2022 common equity tier 1 ratio at 12.05%, tier 1 ratio at 13.65%, and total capital ratio at 16.18%.
These are the holding company’s ratios. The filing separately presented Silicon Valley Bank’s capital position. Keeping the entities separate matters because consolidated parent-company capital and bank-subsidiary capital are not identical pools.
Federal Reserve Regulation Q, section 217.20, specifies the components of regulatory capital. Common equity tier 1 starts with qualifying common equity elements, including retained earnings, subject to regulatory adjustments. It does not start with the proceeds from selling every asset at its disclosed fair value.
Section 217.10 establishes the minimum capital ratios. The risk-based ratios divide the relevant regulatory capital measure by risk-weighted assets. They are prescribed calculations, not comprehensive appraisals of a bank’s liquidation value.
The bank’s well-capitalized classification answered another defined regulatory test. Section 208.43 establishes capital categories for state member banks using specified ratios and supervisory conditions. Meeting that category did not certify that every bond could be sold without a material loss.
SVB’s filing established compliance with those measurements. It did not establish that its capital could absorb the disclosed bond valuation gap without consequence.
Did the AOCI election explain everything?
No. It explains a related exclusion, not the original treatment of held-to-maturity bonds.
SVB disclosed that it elected to exclude most accumulated other comprehensive income, or AOCI, from regulatory capital. Regulation Q, section 217.22, permits eligible banking organizations to make that election and prescribes the resulting adjustments.
For available-for-sale debt securities, this distinction matters. An unrealized loss can reduce accounting equity through AOCI without producing the same reduction in regulatory capital under the election.
The held-to-maturity losses took a different route. Their fair-value decline generally never entered AOCI or earnings in the first place. There was therefore no corresponding market-value charge for the AOCI election to remove from capital.
Attributing the entire omission to the election would confuse two mechanisms. Amortized-cost accounting kept the held-to-maturity valuation gap outside recorded equity. The AOCI election separately insulated regulatory capital from specified changes already recorded in accounting equity.
Did risk weighting capture the difference?
Not as a substitute for marking the portfolio to market.
Regulation Q, section 217.32, assigns standardized risk weights according to the exposure and its obligor or guarantor. That framework addresses credit characteristics. It does not simply insert a bond’s current market-price loss into the capital numerator.
A security can have strong protection against default and still lose market value when interest rates rise. Credit protection does not guarantee a sale price equal to amortized cost.
This was not a distinction invented after SVB’s closure. The Federal Reserve’s November 2022 Financial Stability Report documented declines in the fair value of banks’ fixed-rate securities as interest rates rose. It distinguished those valuation losses from the treatment of held-to-maturity securities in reported capital.
SVB’s securities disclosure made the distinction concrete. The portfolio’s $91.321 billion amortized cost remained far above its $76.169 billion fair value at year-end. A capital ratio calculated under credit-risk rules did not erase that price difference.
When did holding become the problem?
The accounting treatment depended on holding the securities, while depositors’ withdrawal rights did not depend on the securities reaching maturity.
The Federal Reserve’s April 28, 2023 review of SVB’s supervision identified failures in managing interest-rate and liquidity risks. It described a bank exposed to rising rates and dependent on a concentrated depositor base with substantial uninsured deposits.
That combination explains why the valuation gap mattered beyond an accounting note. A bank able to fund a bond through maturity faces a different problem from a bank needing cash before maturity. Selling a depreciated security turns the price difference into a realized result.
On March 10, 2023, the California Department of Financial Protection and Innovation closed Silicon Valley Bank and appointed the FDIC receiver. That event does not retroactively make the December regulatory calculations fraudulent or mathematically wrong. It shows that satisfying capital classifications did not prevent a liquidity failure.
What is the verdict?
No. Silicon Valley Bank’s reported 2022 capital position did not incorporate the disclosed fair-value losses on its held-to-maturity bonds as a deduction from capital. The annual report contained both the regulatory ratios and the $15.152 billion valuation gap, but they measured different things. The ratios supported a regulatory classification. They did not establish that the bank could turn those bonds into cash at their carrying value.
