The March 2023 US regional-banking distress — Silicon Valley Bank failure 10-Mar-2023, Signature Bank failure 12-Mar-2023, First Republic Bank failure 1-May-2023, plus the Bank Term Funding Program created 12-Mar-2023 — was a duration-mismatch / uninsured-deposit-flight event triggered by the 2022-2023 Fed-tightening cycle marking long-duration AFS securities below-water.

The hypothesis is that the 2023 episode meets a tightly-scoped multi-metric checklist on at least 4 of 5 metrics WITHOUT producing a Laeven-Valencia-grade systemic outcome.

SUPPORTED

confidence cueThis is a clear pass for the claim as written. It still applies only to this sample, period, and method.

policy briefClear support

In ordinary language

In plain terms, this asks whether the policy story survives a real-world data check from 2021 to 2024.

plain answer

The data clearly moved in the predicted direction. SUPPORTED

why it matters

This matters because regulatory claims should change belief only when they survive a pre-declared empirical test.

how the test works

It compares 1 country or place units from 2021 to 2024, using a multi metric checklist design.

what was measured
What we checked
  • Regional bank equity index
  • Small bank deposits
what this does not prove

A single test is not the whole truth. It narrows the claim under a specific sample, time period, and method. Strong policy conclusions need the pattern to survive nearby tests, alternative data, and serious objections.

The March 2023 US regional-banking distress — Silicon Valley Bank failure 10-Mar-2023, Signature Bank failure 12-Mar-2023, First Republic Bank failure 1-May-2023, plus the Bank Term Funding Program created 12-Mar-2023 — was a duration-mismatch / uninsured-deposit-flight event triggered by the 2022-2023 Fed-tightening cycle marking long-duration AFS securities below-water. The hypothesis is that the 2023 episode meets a tightly-scoped multi-metric checklist on at least 4 of 5 metrics WITHOUT producing a Laeven-Valencia-grade systemic outcome.

Falsification criterion — what would disprove this

set before the run · honoured after

This hypothesis is considered falsified if:

Evaluate every canonical_metrics row against its pre-registered source, window, and threshold. The hypothesis is SUPPORTED if at least 4 of 5 metrics are MET. It is REFUTED if even counting all pending metrics as favorable cannot reach 4 MET metrics and the confirmed failures cross the pre-registered refutation guardrail. Otherwise the verdict is INCONCLUSIVE until pending data or pending evaluation metrics are resolved.

Detailed result card

Result card — banking_crisis_us_2023_svb_signature

Verdict: supported

Reason: 4 of 5 metrics met threshold (support threshold 4)

Pre-registered rule: SUPPORT if >= 4 of 5 metrics met; REFUTE if <= 1 met (impossible to hit support).

Counts: 4 MET · 0 NOT_MET · 1 PENDING_DATA · 0 PENDING_EVAL

Primary country: USA

Claim

The March 2023 US regional-banking distress — Silicon Valley Bank failure 10-Mar-2023, Signature Bank failure 12-Mar-2023, First Republic Bank failure 1-May-2023, plus the Bank Term Funding Program created 12-Mar-2023 — was a duration-mismatch / uninsured-deposit-flight event triggered by the 2022-2023 Fed-tightening cycle marking long-duration AFS securities below-water. The hypothesis is that the 2023 episode meets a tightly-scoped multi-metric checklist on at least 4 of 5 metrics WITHOUT producing a Laeven-Valencia-grade systemic outcome.

Interpretation

The canonical-case pattern match is satisfied: 4 of 5 pre-registered metrics meet their thresholds, above the support threshold of 4. Each metric is drawn from an independent data source and measures a different causal layer, so the probability of this pattern arising from a data-pipeline fault across all sources simultaneously is low.

Steelman live concerns

See hypotheses/steelman/banking_crisis_us_2023_svb_signature.md for the strongest opposing arguments. Canonical-case multi-metric evidence is a pattern match, not a causal identification — the result card should be read as 'outcome trajectory matches the predicted pattern to degree X' rather than 'policy P caused the outcome'.
