FA-61026 / Bond day-count conventions / Open access

Compounded overnight rate in arrears with lookback: daily accrual uses a 365-day year · case 01

The compounded factor is too small and the period rate is understated.

ROOT CAUSE

The per-day accrual divides by 365 while annualization uses 360.

THE FAILURE

The per-day accrual divides by 365 while annualization uses 360.

Unsuccessful approach: Switching both to 365 changes the convention rather than restoring it.

Case contract

Inputs start, end (business days), a map from ISO date to overnight rate in percent, a lookback in business days, a spread in percent and holidays. Business days are weekdays not in holidays. For each business day d in [start, end), weight n = calendar days to the next business day (or to end for the last one) and rate = the rate published L business days before d. Compound prod(1 + r/100*n/360); the period rate is (prod-1)*360/calendar days*100 plus the spread, rounded to 6 decimals.

Why this case matters

Bond accrual and pricing systems depend on exact day-count arithmetic; a single-day error changes settlement cash.

HELD IN THE MEMBER ARCHIVE

The verified repair and its recorded checks are member-only.

This mechanism has 8 recorded checks per implementation. The open-access tier publishes the failure and the unsuccessful fix; the repaired source that passes every check, and the observations that prove it, are available to members.

Every case sharing this mechanism uses the same contract and the same repair, so this one record is held back for all of them.

Member access is invitation-based. Sign in with your invited account to inspect the repair.

Verification & scope

A deterministic toy contract stated explicitly in the contract field; no claim of conformance to any published convention text. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.

Observations recorded using Python 3.12.14 at 2026-09-29T14:46:51.331703+00:00.
