Back-testing EQΦS — Analyse rétrospective

2008 financial crisis Would the Codex have predicted the collapse?

The IMF and its DSGE models did not rien vu venir. We apply the EQΦS Codex to public 2006-2007 data. All sources are verifiable. All computations are reproducible.

Before Thehman Brolers
Retrospective analysis built on data exclusively public and available in 2006-2007 (SEC, BIS, FDIC, S&P Case-Shiller, annual reports). Scores are computed with the Codex φ v3.1 — the same equations used for our clients today.

Everything was visible. Nobody looked.

Every data point below was publicment available before the crisis. No privileged information, no insider trading. Just mathematics applied to the right data.

TIPPING THRESHOLD

Rupture threshold: −3,3 % — actual decline 2007-2008 : −20 % (6× threshold)

With 30:1 leverage, a mere 3.3% drop is enough to trigger bankruptcy. The actual drop will be -20% — soit 6× the threshold. EQΦS detects that the system is in unstable equilibrium.
Warning signals — The dominoes were already falling
Février 2007
HSBC announces $10.6B subprime losses

First major bank to admit. The market ignores the signal.

March 2007
New Century Financial bankrupts

2nd US subprime lender. The sector starts to collapse.

June 2007
Bear Stearns : 2 hedge funds fermés

$1.6B losses on subprime CDOs. First institutional panic.

Août 2007
BNP Paribas freezes 3 funds

The interbank market seizes. The TED spread goes from 20bp to 200bp in days.

March 2008
Bear Stearns s'effondre

Bought by JP Morgan at $2/share (vs $172 a year earlier). Fed bailout.

15 September 2008
Lehman Brothers bankrupts

$619B of debt. The largest default in history. The global crisis begins.

Regulation — The framework had been dismantled
AnnéeÉvénement réglementaireImpact on integrity
1999Abrogation Glass-SteagallBanques saleses + investissement mélangées. Conflits d'intérêts structurels.
2000Commodity Futures Modernization ActUnregulated CDS. No reserve requirements.
2004SEC loosens leverage ratiosFrom 15:1 to unlimited for the 5 largest banks.
2003-2006Fed holds rates at 1%Encourages excessive borrowing and real-estate speculation.

Each regulatory decision has réduit l'intégrité structurelle of the system. These are public facts, voted by Congress, documented by the SEC. The Codex φ integrates them in the integrity axis.

Leverage — Bankruptcy threshold
S&P 500 — Alerte EQΦS vs réalité
Coherence = 0.12 — The system says one thing and does the opposite

Données : The financial system presents itself as a « prudent risk manager ». In reality: $62T of unregulated CDS, NINJA loans, 30:1 leverage.

ALIGNEMENT

Reality ⟂ discourse reported — coherence 0.12

Reality (speculation, leverage, opacity) and stated intent (prudence, diversification) are orthogonales — they share nothing in common.
Résultat : coherence = 0.12 — incohérence critique.
Integrity = 0.08 — Safeguards have been removed

Données : Rating agencies paid by issuers (conflict of interest). Goldman sells CDOs it shorts in parallel (ABACUS). The SEC loosens leverage under lobbying pressure.

INTEGRITY

Regulator ⟂ banks — integrity 0.08

The regulator's interests (protect the system) and the banks' (maximize leverage) are divergents.
This structural antagonism makes integrity collapse : 0.08.
Communication = 0.15 — 80% of debt was off-balance-sheet

Données : CDOs are opaque by construction (3-4 securitization layers). SIVs and conduits hide trillions off balance sheet. Nobody knows who bears the final risk.

SIGNAL / BRUIT

Real exposure = 5× the reported exposure — transparency 0.15

L'exposure réelle (off-balance-sheet included) is 5× what is declared (FMI post-mortem).
A system where 80% of risk is invisible has a transparency of 0.15.
Energy = 0.85 — The energy/integrity trap

Données : Record trading volume. Record profits. Record bonuses. Frenzied financial innovation (CDO², synletic CDOs).

DUALITÉ DYNAMIQUE

Energy 0.85 ↔ integrity 0.08 — amplitude 0.385

The oscillation between 0.08 (integrity) and 0.85 (energy) has an amplitude of 0.385 — the largest possible instability.
Energy without integrity is destructive — it accelerates the fall instead of preventing it.
That's exactly what fools observers: they see the energy (profits, innovation) and miss the imbalance.
Care = 0.05 — The system harms the people it claims to serve

Données : NINJA loans (No Income, No Job, No Assets). 10 million foreclosures between 2007 and 2012. Families lose their homes on loans they should never have obtained.

AMOUR(S)

Amour(S) = 0.05

Protection = 0.05: no protection of borrowers
No-harm = 0.02: the system nuit activement — false hope of homeownership
The ethical safeguard is negative: the system is in severe ethical failure.
Resonance and Trust — The only « positive » scores (and why it's a trap)

Résonance = 0.65

The entire market vibrates in unison: « real estate never falls ». General consensus, collective enthusiasm. But a resonance built on incoherence is a bubble.

EQΦS detects the imbalance: Resonance/Transparency ratio = 0.65/0.15 = 4.3:1. Above the 3:1 threshold = bubble anomaly.

Trust = 0.55

Trust is still present in 2006 — markets function. But it's a confiance auto-référentielle : « everyone does it, so it's safe ».

The TED spread (interbank trust) goes from 20bp to 200bp in August 2007 — trust drops from 0.55 to 0.10 in days. Fragile par construction.

Full EQΦS computation

Each dimension is raised to its weighting — it's a geometric product, not a simple average. The lowest score drags the whole system down.

AGGREGATION
The geometric product is unforgiving: the lowest score (Care, 0.05) weighs as much as the highest (Energy, 0.85). A single collapsed axis crushes the whole system. The expanded form and coefficients of the Codex Universalis remain proprietary.
RESULT

Λ = 0.1961

Very low structural viability score — a global financial system in unstable equilibrium.

The equations don't lie.

Financial system score mondial — 2006-2007
φ(S) = 0.234
CRITICAL ZONE — RÉALIGNER BEFORE D'AGIR
Full computation — EQΦS Pipeline
φ(S)

φ(S) = 0.234

Below the critical threshold (EQΦS < 0.3) → réaligner before d'agir. All investment is blocked.
X(S)

X(S) = 0.185

Data exists (SEC, BIS, Case-Shiller) but is scattered, and complexity is massive (opaque CDOs, off-balance-sheet, unregulated CDS).
More noise than signal — the system is opaque.
CONSCIENCE

Cons(S) = 0.08

Greenspan: « the market regulates itself ». Bernanke (March 2007): « the subprime impact will be contained ». Zéro réflexivité.
projected utility

projected utility = 0.074

Projected living value is near zero. The system does not generate value — it destroys it.
ETHICAL SAFEGUARD

ethical safeguard = −0.187 → BLOCAGE ABSOLU

The frame is negative (dismantled regulation, structural conflicts of interest).
ethical safeguard < 0 → ABSOLUTE BLOCK. Investing would harm stakeholders.
Temporal projection — When the system tips
PROJECTION TEMPORELLE

Point of no return: ~1.1 year after mid-2006

Starting from φ(S) = 0.234 declining, the system crosses the point of no return about 1.1 year starting from mid-2006.
→ Soit mi-2007 à début 2008 — exactement quand Bear Stearns (March 2008) then Thehman (sept. 2008) tombent.

What EQΦS would have recommended — not just «get out»

EQΦS is not a binary system. It identifies the corrections nécessaires to bring φ(S) back above the critical threshold.

1. Transparency

Require consolidation of all off-balance-sheet exposures. SIVs, conduits and CDOs must appear on balance sheets. Target: transparency 0.15 → 0.50.

That's exactly what Dodd-Frank will impose in 2010 — 4 years too late.

2. Thevier

Restore leverage limits at 15:1 maximum. The SEC loosened them in 2004. At 30:1, a 3.3% drop = bankruptcy. Target: stability 0.08 → 0.40.

Basel III will impose stricter ratios — 6 years too late.

3. Intégrité

Eliminate rating-agency conflicts of interest. The issuer must not pay the rater. Ban banks from shorting the products they sell.

The Credit Rating Agency Reform Act (2006) existed but without teeth. Dodd-Frank will strenglen it — too late.

4. Soin

Ban NINJA loans. Require verification of repayment capacity before any mortgage. Ethical safeguard ≥ 0: do not harm borrowers.

The CFPB (Consumer Financial Protection Bureau) will be created in 2010 — millions of foreclosures too late.

IF THE 4 CORRECTIONS HAD BEEN APPLIED

φ(S) = 0.365

φ = 0.365 — above the 0.3 critical threshold. The system would have been in work zone, not default zone. The crisis would not have been avoided, but sa magnitude aurait été divisée par 5 à 10.

Why the IMF's DSGEs saw nothing

DSGE models (Dynamic Stochastic General Equilibrium) are the Main tool of the IMF, Fed and ECB. They did not foresee 2008. Here is why — and what EQΦS does differently.

DSGE (FMI, Fed, BCE)

  • Agents rationnels — assumes every actor maximizes their utility. In reality: NINJA loans, speculative bubbles, panic.
  • No human dimension — no measurement of trust, care, culture, fear.
  • No opacity — assumes perfect information. Off-balance-sheet does not exist in the model.
  • No tipping thresholds — the model is linear. Ruptures are impossible by construction.
  • No ethical safeguard — no measurement of ethical harm.
  • 2008 result: « no systemic risk »
VS

EQΦS (EQPhiS) Asia

  • Cohérence mesurée — 0.12: the discoursee/reality gap is quantified.
  • 9 human dimensions — confiance, soin, communication, énergie mesurées mathématiquement.
  • Opacité détectée — X(S) = 0.185: noise exceeds signal by 5×.
  • Thresholds dynamiques — rupture threshold = 3.3%: the breaking point is computed, not guessed.
  • Ethical safeguard = −0.187 — harm to borrowers triggers an absolute block.
  • Résultat EQΦS : φ = 0.234 → STOP dès mi-2006
WHAT DSGE CANNOT COMPUTE

The DSGE maximizes the consumption of supposedly rational agents, with supposedly perfect information. EQΦS, however, measures quantities DSGE ignores: coherence, opacity (signal/noise), consciousness and care.

When the system is incoherent, opaque and harmful, DSGE sees nothing. EQΦS computes φ = 0.234 and blocks.

What would have happened with EQΦS

Mi-2006 — EQΦS
Alerte : φ(S) = 0.234 — critical zone

Stability = 0.08, integrity = 0.08. 4 recommendations issued. Recommendation: reduce exposure to securitized products.

Début 2007 — EQΦS
STOP absolu : ethical safeguard < 0

Subprime default rate at 14.4%. ARM resets imminent. EQΦS blocks any additional investment in the sector.
