2026 AUG 12 (NewsRx) — By a News Reporter-Staff News Editor at Insurance Daily News — Data detailed on risk management have been presented. According to news originating from Athens, Greece, by NewsRx correspondents, research stated, “In this article, we investigate whether the crash of the German DAX index following the U.S. tariff announcement in April 2025 is consistent with pre-existing endogenous market fragility rather than a purely exogenous shock.”

The news correspondents obtained a quote from the research from University of West Attica: “The analysis is conducted within the Log-Periodic Power Law (LPPL) framework using the Filimonov-Sornette (FS) specification, complemented by shrinking-window estimation, Ornstein-Uhlenbeck residual diagnostics, surrogate time-series analysis, and a GARCH-based Monte Carlo false-positive assessment. The results reveal a statistically stable critical period preceding the observed market collapse, within which the tariff announcement occurred and was followed by a pronounced market decline. Overall, the findings suggest that the market operated in a regime of elevated systemic fragility, where the tariff announcement may have acted as a triggering event within an already critical state. This study contributes to the literature on financial critical phenomena by providing evidence that LPPL-based critical windows may be interpreted as periods of heightened systemic vulnerability rather than precise crash forecasts.”

According to the news reporters, the research concluded: “From a risk management perspective, such periods may be informative for identifying conditions under which markets are particularly sensitive to external disturbances.”
