Silicon Valley Bank entered 2023 with roughly $91 billion in held-to-maturity securities carrying about $15 billion of unrealized losses, making the buffer functionally illiquid the moment a run started. SVB was not subject to the Liquidity Coverage Ratio at all. That exemption was not a technicality. It was a policy choice with consequences that became visible over 48 hours in March 2023.
The liquidity coverage ratio (LCR) is a Basel III rule requiring large banks to hold enough liquid assets to survive 30 days of severe funding stress without central bank support. For banks under $100 billion in assets, there is no formal LCR requirement, but the underlying logic of the rule applies to every bank that takes deposits and makes loans. Examiners use the same framework, even when the formal ratio does not compute.
This post explains what the LCR measures, how its two components are built, which institutions it covers, and how to get at the same questions for any U.S. bank using public Call Report and UBPR data.
What the Liquidity Coverage Ratio Actually Measures
The formula is straightforward:
LCR = High-Quality Liquid Assets (HQLA) ÷ Total Net Cash Outflows over 30 days
The regulatory floor is 100%. A bank at exactly 100% holds liquid assets equal to its projected outflows under a standardized stress scenario. At 120%, it holds $1.20 for every $1.00 of projected stressed outflows. Covered banks must stay at or above 100% on each business day, not quarterly, not at month-end. Daily.
The rule came out of the Basel III framework and was finalized in the U.S. by the OCC, Federal Reserve, and FDIC in 2014. The underlying premise: a bank that can fund 30 days of severe stress from its own liquid asset buffer buys time: for the stress to ease, for supervisory intervention, for an orderly resolution. Banks that could not do that in 2008 did not get 30 days. Some got 72 hours.
The LCR does not tell you whether a bank will survive a run. It tells you how many days of runway it has before it needs outside support. That is a meaningful distinction for ALCO and for examiners.

The Numerator: What Counts as HQLA
High-quality liquid assets are tiered by how quickly and reliably they convert to cash in stress, not in normal markets. The distinction matters because markets that look liquid in ordinary times can seize up precisely when a bank most needs to sell.
Level 1 assets count at full value with no cap: cash, central bank reserve balances, and U.S. Treasury securities. These form the core of any genuine liquidity buffer. Post-2008, the large-bank industry has shifted heavily toward this tier: reserve balances and Treasuries now account for the large majority of HQLA at covered institutions.
Level 2A assets (certain agency MBS, GSE debt, and sovereign securities meeting specific credit and liquidity criteria) count at 85 cents on the dollar, capped at 40% of total HQLA.
Level 2B assets are more restricted: investment-grade corporate bonds and certain equities, counted at 50 cents on the dollar under the U.S. rule, capped at 15% of HQLA. The haircut reflects the honest possibility that even “liquid” markets for these instruments thin out during a systemic event.
One thing the 2023 failures reinforced: HQLA must be unencumbered. Pledged collateral does not count. Securities sitting on large unrealized losses are technically unencumbered but create a practical problem: selling them realizes the loss and erodes capital simultaneously. That was the corner SVB could not escape. Because the LCR measures HQLA at fair value, it already marks those losses; what it misses is the capital erosion when a bank that excludes AOCI from regulatory capital has to sell, a gap regulators have discussed but not resolved in final rulemaking.
For community banks, the analog is straightforward: what share of your securities book is pledged to secure public deposits, FHLB advances, or other counterparties? That fraction is not available to fund a deposit run.
The Denominator: How Net Cash Outflows Are Constructed
The denominator is where the LCR does its real analytical work. Net cash outflows are not what a bank estimates it would lose; they are what regulators assume it would lose, based on standardized run-rate assumptions applied to each category of liability and committed facility.
Outflow rates by funding type:
- Stable retail deposits (fully insured, with an established relationship or a transactional account): 3% assumed outflow over 30 days
- Other retail deposits, including the uninsured part of retail accounts: 10%
- Non-operational wholesale deposits from nonfinancial companies: 20% if fully insured, 40% if not fully insured or brokered; funding from financial firms runs at 100%
- Committed credit facilities to financial institutions: 40% (committed liquidity facilities to them: 100%)
- Secured funding backed by non-HQLA collateral: 100% (25% applies only to such funding from sovereigns, multilateral development banks and certain GSEs)
The rates are set in 12 CFR 249.32 (the Federal Reserve’s version; the OCC and FDIC rules match).
Those rates encode what we know from historical experience about how different funding sources behave when confidence cracks. Insured retail depositors are slow to move. Uninsured depositors at a bank under stress are not. Institutional counterparties with operational deposits may stay; those without do not.
Inflows offset outflows, because contractual cash coming in from maturing loans and securities reduces the net figure, but caps prevent a bank from assuming its way to a low denominator.
The UBPR net non-core funding dependence ratio (on the UBPR liquidity and funding page) captures a related concept for the broader bank universe: what share of long-term assets is funded by volatile, non-core sources. The LCR formalizes and sharpens the same intuition with regulatory-grade specificity. If your net non-core funding dependence is running above 20%, examiners are going to ask questions that follow the same logic as the LCR denominator, whether or not the formal rule applies to you.
Which Banks the LCR Actually Covers
The LCR is not a universal rule. Under the U.S. tailoring framework finalized in 2019:
- Category I and II firms (generally $700 billion or more in assets, or $75 billion or more in cross-jurisdictional activity): full LCR, calculated daily
- Category III firms ($250 billion or more in assets, or $100 billion or more with elevated risk indicators): full LCR, calculated daily, if weighted short-term wholesale funding is $75 billion or more; otherwise a reduced LCR at 85% of the full requirement, still calculated daily
- Category IV firms ($100 billion to $250 billion): a reduced LCR at 70% of the full requirement, calculated monthly, if weighted short-term wholesale funding is $50 billion or more; otherwise no LCR requirement
- Below $100 billion: no formal LCR requirement
That leaves nearly all of the about 4,300 FDIC-insured banks, every community bank among them, outside the formal rule. Liquidity is assessed through examinations, CAMELS ratings, and ratios drawn from Call Reports and UBPR data.
The 2023 failures reopened a regulatory debate about extending LCR-style requirements to banks with $100 billion or more in assets. That rulemaking has not been finalized. Given the current regulatory posture, the timeline is uncertain, though the direction, at minimum toward stronger liquidity stress testing requirements for mid-size banks, seems durable regardless of the formal rulemaking outcome.
For community bank ALCO: examiners already apply LCR-adjacent logic informally. Banks with high uninsured deposit concentrations, thin liquid asset buffers, and significant FHLB dependence are getting more pointed liquidity questions in exams, even at $500 million in assets.
Getting at LCR Logic for Any Bank from Public Data
For the 99% of banks outside the formal LCR, the same questions are answerable from Schedule RC and Schedule RC-E data in the quarterly FFIEC Call Report, supplemented by the UBPR.
One note on prefixes before you pull anything. The same call report item carries a different prefix depending on which form the bank files. FFIEC 041 and 051 filers report RCON, for domestic offices. FFIEC 031 filers report RCFD on a consolidated basis, and RCFN for foreign offices, so total deposits for an 031 filer is RCON2200 plus RCFN2200 rather than RCON2200 alone. Schedule RC-R Part I (regulatory capital and the capital ratios) moved off RCON with the Basel III revisions of 2014 and 2015 and now uses RCOA on the 041 and 051 and RCFA on the 031; Part II (risk-weighted assets) still reports under RCON and RCFD. Query a single prefix and you will silently drop a whole population rather than get an error, and for an RCON-only query that population is the largest banks in the country.
The liquid asset proxy. Cash and balances due (RCON0081 noninterest-bearing plus RCON0071 interest-bearing) plus unencumbered U.S. Treasury securities (RC-B: RCON0211 HTM at amortized cost, RCON1287 AFS at fair value) plus agency securities from the same schedule, with a rough adjustment for pledged collateral from Schedule RC-B, gives you a Level 1 analog. The quality of this buffer matters as much as the size. A bank with $200 million in Treasuries and $50 million in pledged FHLB collateral has a meaningfully different position than face value implies.
The funding risk proxy. Uninsured deposit concentration (Schedule RC-O: Memorandum item 1, deposit accounts over $250,000 (RCONF051), and for banks with $1 billion or more in assets Memorandum item 2, estimated uninsured deposits (RCON5597), each as a share of total deposits) tells you how much of the liability base is subject to the LCR’s heavier run assumptions, up to 40% for uninsured wholesale deposits. A bank where 40% or more of deposits are uninsured has a funding profile that warrants detailed liquidity scenario analysis, regardless of LCR applicability. Net non-core funding dependence from the UBPR gives you a single summary read across both metrics.
The hidden stress factor. Unrealized losses on available-for-sale securities (Schedule RC-B: RCON1773 fair value minus RCON1772 amortized cost for AFS, and RCON1771 minus RCON1754 for HTM) tell you something raw asset totals do not. A bank with $400 million in agency securities and $60 million in unrealized losses has a materially weaker liquidity position than the face value implies, because selling those securities into a stress event simultaneously erodes capital. This is the SVB lesson. It does not show up cleanly in any single UBPR ratio; it requires combining the securities schedule with the equity reconciliation.
The BankRegReports platform surfaces all of these (liquid asset share, uninsured deposit concentration, net non-core funding dependence, securities unrealized loss exposure) normalized and peer-benchmarked, for every FDIC-insured bank across 24-plus years of quarterly history.
What Examiners Are Looking For
Even without a formal LCR requirement, liquidity examination at community banks follows a consistent framework. Examiners look at:
Liquid asset adequacy. Cash plus unpledged investment securities as a percentage of total assets. A ratio below 10% draws scrutiny. Below 7% in a bank with elevated uninsured deposits is a supervisory concern in most regions.
Funding concentration. Any single funding source exceeding 10–15% of total liabilities (brokered deposits, FHLB advances, municipal deposits) gets a dedicated discussion in the liquidity section of the exam. The concentration threshold is not a hard number, but the questions start at 10%.
Contingency funding plan credibility. Banks are expected to have a written, tested contingency funding plan. “Tested” means you have actually called your FHLB and confirmed your available borrowing capacity under stressed collateral values, not assumed it from the master commitment.
Uninsured deposit runoff. The 2023 experience accelerated this line of questioning at mid-size institutions. Examiners now ask for internal stress scenarios that model partial and full runs on uninsured deposit concentrations, with specific attention to the 30-day window.
For board reporting, the minimum disclosure should be: liquid asset ratio, uninsured deposit percentage, available FHLB capacity as a share of total assets, and any deterioration in AFS unrealized loss position. Those four numbers, trended over four to six quarters, give a board the LCR-equivalent read without the formal calculation.
Frequently Asked Questions
What is the Liquidity Coverage Ratio? A Basel III regulation requiring large banks to hold HQLA equal to at least 100% of projected net cash outflows over a 30-day stress period. LCR = HQLA ÷ Net Cash Outflows.
Which banks must comply with the LCR? Under the 2019 tailoring rules, Category I and II firms (generally $700 billion or more in assets, or significant cross-jurisdictional activity) face the full LCR, calculated daily. Category III firms face the full LCR if weighted short-term wholesale funding is $75 billion or more, and an 85% version, still daily, otherwise. Category IV firms ($100 billion to $250 billion) with $50 billion or more in weighted short-term wholesale funding face a 70% version calculated monthly. Banks under $100 billion in assets face no formal LCR requirement.
What are high-quality liquid assets? Assets a bank can convert to cash quickly with minimal loss in stress. Level 1 (cash, reserves, Treasuries) counts at 100% with no cap. Level 2A (agency securities, qualifying sovereign debt) counts at 85%, capped at 40% of HQLA. Level 2B (certain corporate bonds, equities) counts at 50% under the U.S. rule, capped at 15%.
How are outflow rates determined? By regulation, not by the bank. Stable insured retail deposits: 3%. Other retail deposits: 10%. Non-operational wholesale deposits from nonfinancial companies: 20% if fully insured, 40% if not. Committed credit facilities to financial institutions: 40%, and liquidity facilities to them 100%. Secured funding backed by non-HQLA collateral: 100%. The rates are in 12 CFR 249.32. The rates encode historical run behavior, not bank-specific assumptions.
How do I assess liquidity for a bank not subject to the LCR? Use Schedules RC, RC-E and RC-O from the Call Report plus UBPR ratios: liquid asset share, uninsured deposit concentration, and net non-core funding dependence. Add unrealized securities losses from Schedule RC-B. BankRegReports surfaces all of these, peer-benchmarked, for every U.S. bank.
What did SVB reveal about LCR limitations? That unrealized losses on HQLA can make a technically sufficient buffer functionally insufficient. The LCR counts HQLA at fair value, so unrealized losses do shrink the buffer, but the ratio does not capture the capital hit a bank takes when it has to realize those losses. Selling deeply loss-positioned securities to fund a run erodes capital simultaneously, a dynamic the ratio does not capture directly.
