Stablecoin redemption dependencies

Figure 01 / 12

Separate probability, severity, and exposure

The simplified one-year expected loss is PD × LGD × EAD = $61,354.80. PD is 4.14%, LGD is 52.00%, and EAD is $2,850,000. This is a teaching expected-value calculation, not an accounting allowance method or a capital standard.

Figure data and text version

Input	Value	Unit
PD	4.14	Percent over one year
LGD	52	Percent of exposure lost conditional on default
EAD	2,850,000	USD at default
Expected loss	61,354.8	USD over the stated horizon

A displayed token quantity does not itself prove that fiat can be obtained at the expected time and value. The redemption path depends on several entities and conditions.

A custodian or conversion route fails while the customer expects immediate cash.

All amounts, rates, capacity limits, and outcomes in this case are synthetic. The three conditions are separate assumptions for comparison. A better result in the response condition is not measured proof that the proposed control causes that improvement. The figures expose the calculation and its limits; a real deployment needs its own evidence.

Read the result

The case has $2,850,000 of exposure. Its stated one-year PD and LGD imply $61,354.80 of expected loss, while the cover analysis leaves $1,660,000.00 of stress exposure. Monthly cash coverage is 0.56×. These are separate measures: one describes an average under probability assumptions, one describes available cover, and one describes a period’s funding capacity.

Probability and severity move the result together

Each cell is the same exposure multiplied by the row default probability and the column loss severity. The grid makes joint stress visible. A downturn can affect both factors; the calculation does not assume that the two causes are independent.

Recorded collateral and eligible cover

The collateral record is $1,600,000, but a 45% illustrative haircut leaves $880,000.00 eligible in this scenario. Reserve cover adds $310,000. The resulting uncovered exposure is $1,660,000.00. Eligibility also needs enforceability and operational access; this arithmetic does not establish either.

Recorded collateral	1,600,000

Recorded reserve	310,000

Cash available for the period’s debt service

Defined cash available is $117,800.00 against $210,000.00 of debt service, for a 0.56× ratio. The ratio uses one period and one defined cash measure. It does not establish affordability, suitability, or a required underwriting threshold.

Component	USD	Meaning
Cash available	117,800	After the expenses included in this illustration
Debt service	210,000	Principal and interest due in the same period
Cash after debt service	-92,200	Negative means a modeled shortfall

A constant-hazard illustration

The curve converts the stated one-year PD of 4.14% to a constant monthly hazard using h = 1 − (1 − PD)^(1/12). Survival after 12 months is therefore 1 − PD. Constant hazard is an assumption; seasonality and changing exposure are omitted. Horizontal positions are the labeled observations or scenarios; equal spacing does not imply equal numerical increments.

M0	100

M6	97.91
M8	97.22

M12	95.86

Cumulative expected loss at comparable age

This curve multiplies cumulative modeled default probability by a fixed EAD and LGD. It is useful for separating observation age from the chosen assumptions. It omits amortization, recoveries over time, prepayment, and changing utilization. Horizontal positions are the labeled observations or scenarios; equal spacing does not imply equal numerical increments.

Figure 07 / 12

Expected loss sensitivity to PD

Exposure stays at $2,850,000 and LGD stays at 52.00% while PD changes. The linear relationship follows the simplified expected-loss formula. It is not evidence that real-world losses respond linearly to economic stress. Horizontal positions are the labeled observations or scenarios; equal spacing does not imply equal numerical increments.

One-year PD	Expected USD

3%	44,460

12%	177,840
20%	296,400

A shared dependency can dominate exposure

The four amounts are disjoint portions of this case’s exposure. The largest bucket represents one shared supplier, funding source, or other specified dependency. Counting customers alone would not reveal this common loss driver.

Dependency bucket	Exposure USD
redemption and custody chain — primary	1,140,000
Independent group B	855,000
Independent group C	570,000
Independent group D	285,000

Figure 09 / 12

A weak month can disappear inside an average

The six-month path applies explicit seasonal factors to the defined monthly cash amount and compares it with fixed debt service. These are constructed cash assumptions, not a forecast. A negative month needs a funding or terms response even when the average ratio looks comfortable. Horizontal positions are the labeled observations or scenarios; equal spacing does not imply equal numerical increments.

Month	Cash available	Debt service
M1	82,460	210,000
M2	100,130	210,000
M3	129,580	210,000
M4	106,020	210,000
M5	153,140	210,000

Terms belong in the decision record

This record concerns stress stablecoin and custody exposure. A binary approval omits the amount, observation horizon, cover assumptions, and review trigger. Retaining those terms makes the decision reproducible and identifies when changed facts require another assessment.

Figure data and text version

Field	Illustrative value
entity	Stablecoin redemption dependencies
exposure_usd	2,850,000
horizon	One year for PD; one month for cash coverage
pd_percent	4.14

review_trigger	A custodian or conversion route fails while the customer expects immediate cash.

One cause can affect several loss components

The stress path connects redemption and custody chain to repayment cash, default probability, recovery, and funding needs. Arrows state the scenario’s assumed causal chain. They are hypotheses to test with evidence, not proof that every affected customer will default.

Figure data and text version

Stage	Mechanism
Dependency shock	A custodian or conversion route fails while the customer expects immediate cash.
Cash pressure	Receipts fall or essential payments move earlier
Default and severity	Repayment probability and recovery can both worsen
Response	Reassess terms, usable cover, and exposure within the approved process

Expected loss, uncovered exposure, and cash gap

Expected loss ($61,354.80), uncovered exposure ($1,660,000.00), and monthly cash gap ($92,200.00) answer different questions. The bars are deliberately separated measures and must not be added. A low expected value can coexist with a large stress exposure.

Expected one-year loss	61,354.8
Uncovered stress exposure	1,660,000
Monthly cash gap	92,200

Connect the result to the system

Stress usable access, counterparty concentration, timing, and conversion assumptions.

Check the population, evidence, permitted action, and actual effect together. A balanced calculation can still use the wrong population; a successful response can still leave an unknown financial outcome. The case’s numerical result applies only to its stated assumptions.
