Market conditions

Experimental index of four market signals; not a recession probability.

Static retained snapshot: generated 2026-08-21; newest market input 2026-08-20. JavaScript attempts to load the latest published reading. Source dates, not page-build time, determine freshness.

How to read this index

Higher means more stress in this experimental 0–1 market index; lower means less. It is not a recession probability.

Historical values are retrospective replays. The static retained snapshot was generated 2026-08-21; its newest market input is 2026-08-20. The chart may refresh to a newer reading: use the date and category displayed with that reading.

What it cannot see: the reading says nothing about exogenous shocks — a war, a pandemic, a policy accident — that arrive from outside its four market drivers. Its retrospective record on credit-cycle drawdowns is mixed: elevated ahead of the dot-com peak, only watch before the 2008 crisis, and no elevated lead before the 2020 drawdown. Read it as a monitor, not a proven leading indicator.

Historical index and conditional future paths

Solid line: historical index. Dashed paths: conditional on authored future inputs, with no assigned probabilities. They are separate from the sealed prediction.

History alone uses a 0–0.66 frame (extending if needed). With future scenarios visible, the frame is 0–1 so stress paths are not clipped. The line steps at quarter ends by construction — daily movement enters only through quarter-to-date driver means. Historical points are replays computed from today’s source vintages, not an archive of values published on those dates.

Scenario assumptions and how to read the paths

Optimistic means lower index stress, pessimistic means higher stress, and reference holds the current drivers unchanged. None is a most-probable forecast; no probabilities or confidence intervals have been established.

Authored inputs held in each future quarter; no probability ranking
Scenario10y–2y yield spread (pp)Baa–10y credit spread (pp)VIXCAPE
Optimistic · easing market stress11.51430
Pessimistic · higher market stress-0.543540
ReferenceHold all four origin driver inputs unchanged. The index may still move as smoothing and retained history evolve.

The provisional quarter is assumed to close unchanged. The model then processes the stated inputs once per future quarter. Its retained inversion memory and smoothing can change the reference index even when drivers stay constant. The 0–1 scale accommodates all scenarios; its values are not recession probabilities. “Optimistic” does not imply an investment return.

How to read the fragility view

What the number is

A single 0–1 score summarising market conditions associated with credit-cycle stress — an experimental index, not a measurement of every private balance-sheet exposure. It combines four families of public market driver: the term structure of interest rates, a credit spread, equity volatility, and an equity valuation level. Higher means a higher combined market-conditions score under this method — not a higher probability of any event, and not a reading of the debt-service, refinancing, contagion, external or fiscal buffers dimensions named above, which this index does not feed and do not feed it. It does not directly observe household debt service, corporate refinancing needs, cash buffers or bank positions; those belong to separate, separately named models.

The model recomputes the score daily and publishes it to cloud storage; this page reads that published copy (with a baked fallback that is labelled when stale). The inputs have different cadences: the market legs publish daily, usually a day or two apart, while the valuation leg is an annual curated value held constant through the year — so a daily publication is not four daily observations. Daily movement enters only through quarter-to-date driver means — a single day cannot swing the reading on its own, which is why the line is smooth and why a still-open quarter is marked provisional.

InputPlain explanationLimitation to retain
Treasury yield curve The difference between long- and shorter-term Treasury yields; recent flat/inverted conditions raise this component. Retained history can keep it elevated after the current curve changes.
Corporate credit spread The extra yield on Baa corporate debt relative to Treasuries. A market financing indicator, not the amount of debt or a measure of total balance-sheet losses.
Equity volatility The VIX measure of expected equity-market volatility. Often responds during a sell-off; it does not necessarily lead the shock.
Equity valuation Share prices relative to long-run earnings, using CAPE. Annual input in this implementation; high valuation alone does not identify when a decline will occur.

The yield-curve input is the 10-year Treasury yield minus the 2-year yield. See the rates, their spread and the market index together in our yield-curve guide.

What the regimes mean

The four regime names are bands of the combined score, not a count of stretched legs — a weighted composite does not enforce a fixed number of drivers being stretched at any given band. Elevated is the one precisely defined boundary: the reading is above 0.40, the sealed tripwire's own public criterion. Benign, Watch and Fragile are authored categories on either side of it: the thresholds were chosen by this model's authors, and crossing one is a statement about the combined index, not a calibrated probability of any event and not a tally of how many of the four inputs are individually stretched.

What it is not

It is not a market call, not a recession probability, not a timing signal, and not a demonstrated forecasting record. It is model-conditional: it says what this model reads from these drivers. Its retrospective record on credit-cycle drawdowns is mixed (stated above), and it says nothing about exogenous shocks — a war, a pandemic, a policy accident — that arrive from outside its market drivers.

Why the US line is different

The US reading is the sealed instrument: all four legs are the United States' own published series — three at daily frequency, the valuation leg an annual curated value — and the same instrument stands behind a sealed, dated, scoreable prediction in the ledger. When it is wrong, it will be scored in public like any other entry. Sealing makes the record checkable; it does not, by itself, make the model right.

Why the other lines are approximate

No other economy has four keyless daily drivers of its own. The comparison lines fill the gaps with declared proxies — a regional credit spread instead of a national one, a global volatility index, market capitalisation over GDP as the valuation leg, normalised against that country's own history. Each substitution is listed on the country card on the home page.

That makes each of them useful for watching its own economy's direction of travel. It does not make them the same instrument as the US index, and it does not support ranking economies against each other — the same numeric value need not represent the same exposure in two countries. They are approximate: not sealed, not scored, and never published as predictions.

Where we publish nothing. A country reading is not the US instrument pointed at other data: with legs missing, and monthly, lagged inputs, it would be a different model with a different calibration — and it would need its own sealed lanes before it deserved to be called a prediction. Showing one under the same name is exactly the failure this ledger exists to prevent.
