GTS-1Y · Grid Term Spread — 1 year

GAP-H100-R1Y minus GAP-H100 spot, in US$ per GPU-hour. Positive = commitment premium over spot (contango); negative = commitment discount (backwardation). The specification's stated defence — the level embeds a provider-class premium and the change is the signal — fails on the stored data because the change was entirely the spot leg's, sign-inverted.

Class — and why

Arithmetic on two Grid legs (GAP-H100-R1Y − GAP-H100 spot). SUSPENDED by methodology change notice 2026-08-14 §1: with a constant reserved leg the series reduces to (6.4645 − GAP) — correlation −0.999999983 with its own spot leg — and carries no independent term-structure information.

Suspension. Effective 2026-08-22; final prints dated 2026-08-21per the notice. Published history is not removed, revised or retroactively annotated — each value stands as published on the information set of its day. From the effective date the series appears on /api/print with status “suspended” and no value. Notice of record: /standards/notices/2026-08-14-instrument-actions.

Ⅲ · Normalisation and construction rules

the named adjustments, in order

None beyond the legs' own — the print is the subtraction of the two stored legs of the same date.

Ⅳ · Minimum observations and withholding

below which the print is flagged · below which it is not published

The spread printed only when both legs existed on the date. No independent floor — inherits the legs'.

Ⅴ · Disclosures

verbatim from the derived-series registry · the same string every surface carries

GTS-1Y — Defect disclosed 2026-08-14: the reserved leg has zero variance, so GTS-1Y reduces to a constant minus GAP-H100 spot — correlation −1.0 with the spot leg across every print. It carries no independent term-structure information. Suspended from 2026-08-22 (methodology change notice 2026-08-14); published history stands as-published.

This page renders the method of record for GTS-1Y; it does not define it. Printed values are never rewritten — a change in method is announced by notice before it affects a print (publish-before-effect); a correction restates only what the day’s own information set supported.
