Fed SOMA Treasuries held outright

What it is

Fed SOMA Treasuries held outright — registry key soma_treasury_bn.

Fed System Open Market Account Treasuries held outright (notes+bonds+bills+tips+frn), NY Fed SOMA summary, weekly.

Data-pyramid tier

T0 — Raw input. This metric sits at the raw input layer of the platform’s six-tier data pyramid (T0 raw inputs → T5 actionable read). The tier reflects how far the value is from a raw measurement — not how strongly it is validated. Abstraction and validation are separate axes: a higher tier is not a claim of stronger evidence.

Horizon & validation

No validated skill horizon is on file for this metric — read it as context / a data carrier, not a validated edge. Stamps are added only when a gated research verdict lands.
