Treasury repo margin threshold
When does repriced Treasury collateral trigger a cash margin transfer after repo interest, a contractual threshold and a minimum transfer amount?
This experiment changes declared financial assumptions and calculates their consequences. The starting figures are illustrative; the model does not inspect your accounts or require a live market feed. Run the question free, compare an alternative and inspect the calculation receipt.
Run this experimentWhat the published starting values calculate.
Cash margin required by the declared clause: 51,266.67 USD.
The declared transfer threshold creates a discrete cash requirement. Posted margin remains an encumbered asset rather than a realised investment loss. Initial financing is already outstanding and is not added again to available cash.
| Calculated outcome | Value and unit |
|---|---|
| Cash margin required by the declared clause | 51,266.67 USD |
| Largest funding deficit | 1,266.67 USD |
| Repo interest accrued to margin day | 3,266.67 USD |
A funding deficit represents unmet obligations under this fixed schedule; no borrowing facility is inferred. A zero deficit means only that the declared schedule passes the stated calculation.
The illustrative date origin is ; the recorded seed is 42 and the model is yieldguard-experiments-1.2.0. Dates and values are scenario inputs, not current observations. Readable percentages may be rounded; the evidence file preserves the kernel values.

Starting assumptions and units.
| Assumption | Starting value |
|---|---|
| Cash available for margin | 50000 USD |
| Initial Treasury collateral value | 1000000 USD |
| Initial financing haircut | 2 % |
| Maintenance collateral haircut | 2 % |
| Collateral price change | -5 % |
| Annual repo rate, ACT/360 | 4 % |
| Margin calculation day | 30 days |
| Unsecured exposure threshold | 1000 USD |
| Minimum cash transfer | 5000 USD |
| Horizon | 45 days |
What the result establishes and leaves open.
The calculation is conditional on declared input values, model conventions and horizon. Reproducing the result checks the disclosed calculation path; it does not establish forecasting accuracy or the suitability of a real treasury decision.
- Illustrative user assumptions; no live market data or calibrated forecast.
- Results apply only to the declared mechanisms, horizon and search bounds.
- Initial repo cash equals collateral value times one minus the initial haircut. A one-off price change is applied on the margin day; repo interest accrues ACT/360. Transfer occurs only when excess exposure above the threshold is strictly greater than the minimum transfer amount.
- An illustrative single-trade cash-margin clause, not a GMRA implementation. Posted margin is encumbered cash, not an investment loss. Repo close-out, netting, coupon treatment and margin return are outside the horizon model.
- No market refresh, AI calculation, trade execution or forecast calibration.
- Receipts are content-addressed local calculation records, not externally signed attestations.
- Deterministic calculation: the seed is recorded for the common receipt contract; this experiment samples no random disturbances.
- Illustrative assumptions; no live data or forecast calibration.
The next useful question.
What initial cash exactly covers the deepest deficit in this deterministic payment schedule?
