Like 1929, The ACWI peak valuation and decay inflection
had as its root causes: overinvestment, terminal cycle bad and defaulting private credit loans, and asset extreme overvaluation. 1929 occurred near an 1807 36/90 :: x/2.5x 1st and 2nd fractal series ending in 1932 and 2026 occurred near the end of an 1982 13/33 year :: x/2.5x 1st and 2nd fractal series, interpolated in a larger 1807 US hegemonic 36/90/90/54-57 year :: x/2.5x/2.5x/1.5-1.6x 4-phase fractal series.

Why 2026 is markedly different than 1929.

The derivative markets focused on hedged expected interest rates bets make 2026 markedly different, with a likely 2026 significantly greater than 1929 initial peak to nadir collapse following 11/26/26-27 day :: y/2.5y/2.5y 3-phase Lammert fractal crash decay Series

The 21st century emergence of a 0.8 + quadrillion dollar derivative market, 80% which has hedges primarily focused on interest rates is an awaiting nonlinear crash conflagration … as most hedge fund modeling on interest rates and private debt collapse did not factor in the rising interest rates associated with the Israeli-Trump war via the Hormuz closure and the sharply escalating oil, gas, and by product global prices. The derivative modeling with a collapsing private credit fund market (KKR, Blackrock, Apollo, Blue owl, Blackstone, Morgan Stanley, Ares, Tricolor, et.al. ) would have predicted falling interest rates with appropriate collateralized derivative bets. The war has caused rising interest rates and the derivative bets are most assuredly upside down.

Fractal groupings (Fractals) are determined by trendlines.

Observation of the ongoing 17 Feb 2026 11/26/27 day :: y/2.5y/2.5y crash decay fractal series shows that day 5 and day 10 of the 26 day 2nd Fractal Series ( a 5/10/8/6 day subfractal series) are below the 11 day 1st Fractal trendline. Days 5,10, 8, and 6 of this 26 day subfractal series are expected to be nadirs with a trendline from day 1 to day 26 of the 26 day 2nd Fractal below all intervening valuations. How negative will this 26 2nd Fractal trendline be with respect to the 11 day 1st Fractal negative trendline? The poorly bet interest rate derivative markets will add to the 2nd Fractal trendline negativity, with an expected acceleration of the negative slope for the 26-27 day 3rd Fractal as a cascading conflation unfolds.

A 1982 13/33 year :: x/2.5x major credit/business fractal cycle is ending analogous to the ending of the 1807 36/90 year :: x/2.5x fractal cycle that peaked on 3 Sept 1929 and nadired in 1932. This 1982 cycle peaked on 25 Feb 2026 for the ACWI global equity composite.

Was it the recent ongoing private credit collapse and asset valuation extreme overvaluation or was it the Israeli-Trump war shock that pivoted and inverted the asset valuation growth to asset valuation decay?

Unfortunately, and on many levels, the effects of ‘an uninitiated needless war’ and against the most important of international UN charter regulations will be unknown. The 11 day first decay fractal began on 17 Feb 2026. The Israeli-Trump war was not initiated until 28 Feb 2026

Gold in USD is following the same 17 Feb 2026 3-phase fractal decay pathway as the SPX as the global composite equity ACWI. GBTC, the 5 day a week tradable proxy for crypto, is following a 5 Feb 2026 13/31-32/26-27 day :: y/2.5y/2y 3-phase fractal decay pathway whose 2nd and 3rd fractal decay nadirs align with gold in USD , the SPX, and ACWI.

With collapsing and private debt default denominated in dollars, assets must be sold to repay those debt obligations. From a fractal perspective, private debt default is the primary precipitate of the asset valuation crash, with the Israeli-Trump war a coincidental event causing a perverse escalation of oil and oil byproduct prices, and seriously causing inflation and impacting the world’s producers and the world’s consumer economy.

The growth and decay of the Asset-Debt Macroeconomic Systems’ tradable assets’ valuations self-assembly in the most efficient mathematical time-based fractal manner possible. At major inflection points (1929 and 2026; 1807 36/90 year and 1982 13/33 year :: x/2.5x 1st and 2nd fractal cycles respectively) – created by asset extreme overvaluation(caused by corporate buy-backs, petrol dollar investment, retirement automatic 401K investment, et al.); private debt default; and excessive private debt accumulation untethered to the underlying ongoing wage and job related real economy – incipient asset valuation fractal decay is interpolated in final fractal valuation peak growth. In 2026 add to the private debt default, debt accumulation relative to job and wage growth, and extreme asset overvaluation … add … a global energy and global critical petroleum byproduct shock – and the 1929 initial peak to nadir fractal valuation decay of 48% will likely be smaller than the initial peak to nadir valuation fractal decay in 2026.

The current new fractal decay model is actually an earlier 2008 identified 3-phase decay series:
