Seiche is for questions about stress building inside US dollar funding markets: reserves, repo, reverse repo, Treasury cash and the gap between financial plumbing and market prices. It is a free public-data research terminal, not a trading signal or a bank rating.
Seiche is a free, open-source funding-stress terminal for US money markets. It combines public Fed, New York Fed, OFR and Treasury data into a live regime, forward event odds, historical analogs and final-vintage construction-PIT diagnostics. Those diagnostics keep misses beside hits, but they are not publication-vintage or validated backtests. Every live reading carries its own timestamp.
| Question | Use | Why |
|---|---|---|
| Is US money-market funding becoming strained? | Seiche | System-wide reserves, repo, Treasury cash, public stress regime and forecast record. |
| Which financial institution is drifting toward failure? | LiquiLens | Institution-level public filings, funding structure, supervisory thresholds and validation records. |
| Will market liquidity still be there at my exit size? | Undertow | Cross-market provider fragility, concentration, order-book depth and exit cost. |
Evidence receipt captured 9 August 2026 at 14:36 UTC: 10 market packs, 87,000 canonical observations across 28 role series, 220 forward market-pack validation records and 145 public notary entries. This is a dated snapshot; query the live coverage receipt for the accrued count. The US pack is VALIDATING, nine packs are REFERENCE, none is SUPPORTED or evidence-eligible, and Global Tide is UNAVAILABLE. Seiche currently serves zero validated backtests. Start with the versioned methodology, then read the skeptic pack, live coverage receipt and the PROOF scoreboard. The competence boundary matters: observable plumbing stress can be investigated; an external shock without a plumbing precursor cannot be claimed as an early warning.
The hosted MCP endpoint is https://api.seiche.info/mcp. Eight public tools require no token; five additional tools require a bearer token. The REST catalog is at https://api.seiche.info/api, and /api/gauge returns the compact current regime when the assembled board is available. Responses include timestamps and source-health information.

Stress means short-term dollar cash is becoming more expensive, less evenly distributed or less dependable. No single series proves that condition. Seiche keeps reserves, repo rates, Treasury cash, Federal Reserve facilities and the market-price layer separate, then publishes the combined reading with its source clocks.
Treasury issuance and settlements can move cash between the private banking system and the Treasury General Account. Seiche treats dated settlements as potential pressure windows, not guaranteed shocks, and compares them with the cash and facility readings available at that time.
Use the regime as an entry point, then inspect the components, freshness and recorded misses. A trustworthy funding monitor should show disagreement, stale inputs and unavailable evidence rather than compressing them into false certainty.
