A U.S. Global Systemically Important Bank must hold total loss-absorbing capacity, or TLAC, equal to at least the greater of 18% of its risk-weighted assets or 7.5% of its total leverage exposure, and it must satisfy a separate floor of eligible long-term debt on top of its regulatory capital. The Federal Reserve sets these TLAC requirements for G-SIBs in Regulation YY at 12 C.F.R. Part 252, implementing the Financial Stability Board’s post-crisis framework so that a failing megabank can be recapitalized by its own shareholders and bondholders instead of by the public.1eCFR. 12 CFR Part 252 – Enhanced Prudential Standards (Regulation YY)2Financial Stability Board. Total Loss-Absorbing Capacity (TLAC) Principles and Term Sheet
Which U.S. Banks the Rules Cover
Eight U.S. banking organizations currently carry the G-SIB designation and therefore fall under the TLAC framework: Bank of America, Bank of New York Mellon, Citigroup, Goldman Sachs, JPMorgan Chase, Morgan Stanley, State Street, and Wells Fargo.3Federal Reserve Board. Global Systemically Important Banks The Financial Stability Board updates the global list every November, scoring each candidate on size, interconnectedness, substitutability, complexity, and cross-jurisdictional activity.4Bank for International Settlements. The G-SIB Assessment Methodology – Score Calculation As of the most recent publication, 29 banks worldwide are designated.5Financial Stability Board. 2024 List of Global Systemically Important Banks (G-SIBs)
Foreign G-SIBs that operate at scale in the United States must house those operations in an intermediate holding company (IHC), and the IHC picks up its own TLAC obligations calibrated to whether it is the group’s designated resolution entity. TLAC does not apply to smaller banks or to regional institutions outside the G-SIB list; those firms are subject to different capital and resolution regimes.
The Two Minimum Ratios
Under 12 C.F.R. § 252.63, every U.S. G-SIB holding company must hold TLAC equal to the greater of two figures at all times: 18% of risk-weighted assets, or 7.5% of total leverage exposure.6eCFR. 12 CFR Part 252 – Enhanced Prudential Standards (Regulation YY) – Section 252.63 The two ratios do different jobs. The risk-weighted ratio scales the requirement to how risky the balance sheet actually is, so a book heavy in speculative lending demands more capacity than one dominated by Treasuries. The leverage ratio ignores risk weights entirely and works as a hard backstop against models that might understate exposure.
The U.S. leverage figure of 7.5% is stricter than the 6.75% floor in the FSB’s international term sheet.7Financial Stability Board. Review of the Technical Implementation of the Total Loss-Absorbing Capacity (TLAC) Standard Both thresholds are fully phased in.
Requirements for Foreign Bank IHCs
An IHC’s numbers depend on its role in the parent group’s resolution plan. A “resolution” IHC, meaning the entity that would actually enter proceedings, must meet the greater of 18% of risk-weighted assets, 6.75% of total leverage exposure, or 9% of average total consolidated assets. A “non-resolution” IHC faces 16%, 6%, and 8% at the three tests.8eCFR. 12 CFR Part 252 – Enhanced Prudential Standards (Regulation YY) – Section 252.165
The Separate Long-Term Debt Floor
Meeting the overall TLAC ratio is not enough. Under 12 C.F.R. § 252.62, a U.S. G-SIB must also hold eligible external long-term debt equal to at least the greater of 6% of risk-weighted assets plus its G-SIB surcharge, or 2.5% of total leverage exposure plus its leverage buffer.9eCFR. 12 CFR 252.62 – External Long-Term Debt Requirement Because the G-SIB surcharge is folded into the formula, a bank in a higher surcharge bucket must issue proportionally more long-term debt. The surcharge itself is calculated under two methods and set at whichever produces the higher number, with most large U.S. banks landing on Method 2 because it accounts for short-term wholesale funding.10eCFR. 12 CFR 217.403 – GSIB Surcharge
Equity and long-term debt do different work in a failure. Equity absorbs the first losses. Long-term debt provides the recapitalization fuel: when the holding company is seized, its long-term bondholders can be left behind in receivership and their claims converted into equity of a successor firm. A dedicated debt floor guarantees that mechanism is always available. Without it, a bank could hit its TLAC total on equity alone and leave regulators with nothing clean to convert.
What Counts Toward TLAC
Only two categories of instruments qualify: regulatory capital and eligible long-term debt.
Regulatory Capital Tiers
Common Equity Tier 1 (CET1) capital, made up of common stock and retained earnings, sits at the top of the loss-absorption hierarchy and takes the first hit. Additional Tier 1 covers instruments like noncumulative perpetual preferred stock that absorb losses while the bank is still a going concern. Tier 2 includes subordinated debt that absorbs losses once the bank has failed.11eCFR. 12 CFR 217.20 – Capital Components and Eligibility Criteria for Regulatory Capital Instruments Each successive tier has looser eligibility criteria but a weaker claim on the loss-absorbing stack.
Eligible Long-Term Debt
To count as eligible long-term debt under 12 C.F.R. § 252.61, an instrument must be unsecured, unguaranteed, governed by U.S. law, and issued with an original maturity of at least one year. It cannot be a structured note, cannot carry an interest rate tied to the bank’s own credit quality, and cannot give the holder any right to accelerate repayment except in a formal insolvency proceeding or after 30 days of missed payments.12eCFR. 12 CFR 252.61 – Definitions Anything that lets a creditor pull out early or complicate the loss allocation is out.p>
Maturity Haircuts
Eligible debt loses credit as it approaches maturity. The full unpaid principal counts if the payment date is two or more years away. Only 50% counts if the maturity falls between one and two years out. Nothing counts inside twelve months.13eCFR. 12 CFR Part 252 Subpart G – Section 252.62 The haircut schedule forces banks to refinance well ahead of maturity. A firm that lets its long-term debt run down will watch its TLAC ratio slide even without absorbing a single loss.
Clean Holding Company Restrictions
TLAC works only if the holding company at the top of the group is structurally simple enough to restructure quickly. To keep it that way, 12 C.F.R. § 252.64 bans a G-SIB parent from taking on several categories of obligations to outside parties.14eCFR. 12 CFR 252.64 – Restrictions on Corporate Practices of U.S. Global Systemically Important Banking Organizations
- No short-term debt with an original maturity under one year to anyone outside the subsidiary group, including short-term deposits.
- No qualified financial contracts (derivatives, repos, and similar) with outside parties, aside from credit enhancements.
- No instruments that give a holder offset rights against amounts owed to a bank subsidiary by that holder’s affiliates.
- No cross-guarantees where the holding company backs a subsidiary liability containing default triggers tied to the parent’s resolution, and no subsidiary guarantees of parent liabilities.
The result is that the holding company operates as a funding vehicle sitting above the operating subsidiaries, with no tangled outside obligations to trigger a chain of defaults when regulators step in.
Internal Versus External TLAC
External TLAC is what the resolution entity, usually the top-tier holding company, issues to public investors. Those investors are on notice that they stand first in the loss queue if the bank fails.15Financial Stability Board. Principles on Loss-Absorbing and Recapitalisation Capacity of G-SIBs in Resolution
Internal TLAC is pre-positioned at material subsidiaries, particularly foreign ones, through intercompany loans or capital instruments from the parent rather than issuance to the outside market.16Bank for International Settlements. Internal TLAC – Executive Summary If a subsidiary runs into trouble, the parent can write down or forgive that intercompany claim, recapitalizing the subsidiary without a local insolvency case. Losses flow up to the resolution entity, where external creditors ultimately absorb them.
The arrangement supports a single-point-of-entry resolution strategy: only the parent enters proceedings, subsidiaries keep operating, and host-country regulators can see that adequate capacity already sits within their borders before the crisis begins.
What Happens If a Bank Falls Short
A G-SIB that drops below the minimum ratios does not shut down, but automatic penalties on capital distributions and discretionary bonuses kick in and tighten as the shortfall grows.17Federal Register. Total Loss-Absorbing Capacity, Long-Term Debt, and Clean Holding Company Requirements The scale runs in four tiers based on how much of the required buffer the bank still holds:18eCFR. 12 CFR 252.63 – External Total Loss-Absorbing Capacity Requirement and Buffer
- More than 75% of the buffer remaining: distributions capped at 60% of eligible retained income.
- 50% to 75% remaining: the cap drops to 40%.
- 25% to 50% remaining: only 20% can be distributed.
- Below 25%: no distributions or discretionary bonuses at all.
The tiered structure applies separately to the risk-weighted TLAC buffer and the leverage TLAC buffer, and the bank is bound by whichever produces the lower payout limit. A bank with negative eligible retained income that sits below either buffer is fully locked out of distributions and bonuses unless the Federal Reserve grants an exception.
How TLAC Works in a Resolution
The point of the framework is what happens if a G-SIB actually fails. Under Title II of the Dodd-Frank Act, the FDIC has Orderly Liquidation Authority, and its preferred approach is single-point-of-entry: only the parent holding company is placed into receivership while the operating subsidiaries keep running.19FDIC. Overview of Resolution Under Title II of the Dodd-Frank Act
The FDIC transfers substantially all of the holding company’s assets, chiefly its ownership stakes in the subsidiaries, into a temporary Bridge Financial Company. The holding company’s equity and long-term debt stay behind in the receivership, where shareholders and bondholders absorb losses in statutory order. The Bridge Company then uses pre-positioned internal TLAC, often by forgiving intercompany loans, to recapitalize any subsidiary that took losses. Customers, depositors, and counterparties of the operating banks may see no disruption at all. The losses land where the framework intended: on the parent’s investors.
Reporting and Public Disclosure
G-SIBs file the FR Y-15 Banking Organization Systemic Risk Report with the Federal Reserve quarterly, due 50 calendar days after each of the first three quarter-ends and 65 calendar days after December 31.20Federal Reserve Board. FR Y-15 Banking Organization Systemic Risk Report The data feeds the surcharge calculation and systemic risk monitoring.
On the public side, a G-SIB must describe in plain language the financial consequences unsecured creditors would face in a resolution proceeding. That disclosure has to appear in offering documents for every eligible debt security the bank issues and must also be available either on the bank’s website or in its public financial or regulatory reports.21eCFR. 12 CFR Part 252 Subpart G – External Long-Term Debt Requirement, External Total Loss-Absorbing Capacity Requirement and Buffer, and Restrictions on Corporate Practices Anyone buying a G-SIB’s long-term debt is meant to see, in the deal documents, that they are carrying a risk the public used to carry.
