Yield shock and bill value
What is the mark-to-market effect of a yield change before a bill matures?
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.

Bill value at observation/sale day: 979,865.77 USD.
Value changes separate calendar-time accrual from the explicit yield shock. The timeline is a marked-value path, not immediately settled cash.
| Calculated outcome | Value and unit |
|---|---|
| Bill value at observation/sale day | 979,865.77 USD |
| Initial bill price | 980,655.56 USD |
| Value change from calendar time alone | 3,171.93 USD |
| Additional effect of changed yield | -3,961.72 USD |
Cash-funding feasibility is not assessed. Modelled value, interest or a conditional fee quote does not establish available settled cash.
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.

- Illustrative assumptions; not observed customer evidence.
- Authority
- A content-addressed request and model-context record. No external signature, output attestation, independent assurance or production authority is established.
Starting assumptions and units.
| Assumption | Starting value |
|---|---|
| Bill face value | 1000000 USD |
| Initial annual yield | 4 % |
| Yield change | 1 % |
| Initial days to maturity | 180 days |
| Days elapsed | 30 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.
- 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.
- Timeline is a value series, not settlement availability. Cash-funding feasibility is not assessed.
The next useful question.
Do redemption proceeds arrive before the payment deadline?

In the Laboratory, edit the assumptions and compare the result. Planned Macrovision would connect approved organisational evidence, material changes, assigned exception review and preserved decisions. AI prepares and explains; approved models calculate; your team decides.
Planned — not accepting paid engagements. The public Macrovision walkthrough follows a synthetic late-receipt case. The walkthrough demonstrates intended work and does not activate customer monitoring or imply that every Lab question is a supported paid workflow.
Financial assumptions are not automatically sent into an enquiry, analytics or a shared result URL. Any later transfer to a hosted workspace must be explicit.
