Sensitivity to evidence weight

How sure of itself should the model be? It treats each signal as separate evidence and multiplies their effects together. Several signals overlap, such as the credit-card and mortgage delinquency rates, so one underlying development can be counted more than once and the result can look more certain than the evidence justifies. The evidence weight w softens every signal's effect: at 1 they count in full; at 0.5 each is halved in strength, so x4 becomes x2 and x0.25 becomes x0.5. Each row shows today's probabilities at that setting. If the full-strength row looks overconfident, for example if its contraction odds sit well below what markets or forecasters put on a recession, a lower weight is worth considering.

Signal methodology

Probability = initial prior x the current multiplier (LR) of each active signal, rescaled to 100% and recomputed every run. Active state highlighted yellow. (no change) = same state as the previous run.

10Y-2Y Treasury spread [FRED | pct pts] (T10Y2Y)

Difference between 10-year and 2-year US Treasury yields. Negative (inverted) curve has preceded every US recession since 1970.

Unemployment, bachelor's degree+ [FRED | percent] (LNS14027662)

Unemployment rate for workers with a bachelor's degree or higher (LNS14027662). Historically runs ~0.55x the overall rate (~2-2.5% in normal conditions). Rising relative to HS-graduate unemployment is the key S5 structural disruption signal.

Job openings (JOLTS total nonfarm) [FRED | thousands] (JTSJOL)

Total nonfarm job openings from the BLS Job Openings and Labor Turnover Survey. Used as a proxy for aggregate labor demand. Rising YoY = expanding hiring appetite; falling YoY = demand contraction. Monthly, released with ~5-week lag.

Consumer vs mortgage DQ spread SHADOW - not applied [COMPUTED | pct pts] (DQ_SPREAD)

Spread between credit card delinquency (DRCCLACBS) and single-family mortgage delinquency (DRSFRMACBS). Imperfect proxy - payment hierarchy means consumers default on mortgages last, so widening partly reflects prioritisation not quality. Retained as a noisy supplementary signal with reduced weighting (ratios closer to 1.0). Derived from existing FRED signals. Classified on the one-quarter change (delta_4w); before Sep 2026 that metric was always 0, so this signal never moved the vector.

Wage growth, bachelor's degree+ (Atlanta Fed) [FRED | pct (12-month median)] (FRBATLWGT12MMUMHWGBDH)

Median 12-month wage growth for continuously employed workers with a bachelor's degree or higher, from the Atlanta Fed Wage Growth Tracker. Decelerating wage growth for educated workers is a leading indicator of structural disruption (S5). Monthly, ~6-week lag.

US investment grade OAS (ICE BofA) [FRED | percent] (BAMLC0A0CM)

Option-adjusted spread of the ICE BofA US Corporate (IG) index vs Treasuries. Market price of investment-grade credit risk. Directly addresses the existing bright line at 200bps. Pre-GFC normal 80-120bps; COVID peak ~373bps; GFC peak ~600bps. FRED reports it in percent (0.81 = 81bps), so thresholds here are in percent.

10Y real yield (TIPS) SHADOW - not applied [FRED | percent] (DFII10)

The inflation-adjusted yield on 10-year Treasuries (TIPS). Overlay with no LRs, because the direction of its effect depends on why it moved: expected policy rates (tighter Fed; later credit-stress risk, S4), term premium (fiscal and uncertainty; mostly asset prices), or a higher neutral rate (investment boom, faster growth; S2/S3). Read it with labour share: a falling labour share with rising real rates points to an investment-led boom; with falling real rates, to demand-deficient disruption (S5). The right-hand chart splits the nominal 10Y yield into term premium and expected short-term rates.
