The house signals
Seiche's latest funding composite was 44.6, in EROSION. Undertow's funding overlay also read EROSION.
The same Undertow board supplied an important countercase: its only scored investment-grade cell was NORMAL. Only 1 of 9 segments scored, so this is evidence of divergence—not evidence that the other eight segments were calm.
The official context
The latest official SOFR observation was 3.62% on August 12. The latest preliminary DVP outstanding repo-volume observation was $3.397 trillion on August 11.
These official observations anchor the comparison in measured funding data, but they do not turn agreement between two derived funding labels into broad cross-market confirmation.
Why confirmation is limited
Agreement exists at the funding layer: Seiche's composite and Undertow's funding overlay both say EROSION. Confirmation weakens outside that layer because the only scored IG cell says NORMAL and the rest of the board is unscored.
The clean read is limited confirmation. It is stronger than a single-model signal, because two house systems agree on funding, but weaker than a broad stress call, because coverage is sparse and the available IG countercase points the other way.
What would change the read
A later Undertow board with broader scored coverage and stress outside funding would falsify the current limited-confirmation thesis. A reversal in either funding label would also remove the present agreement.
Until then, unscored cells remain unknown. They are not zeros, NORMAL readings, or evidence against stress.
Boundaries
The funding composite and IG tier are derived classifications, not traded prices. Their labels should be evaluated alongside their methods, coverage, and countercases.
The official observations are also bounded: SOFR is not a measure of every funding condition, and the DVP repo observation is preliminary and may be revised. The source dates differ, so this is a layered snapshot rather than a synchronized market close.
