Beyond the Hype: A Conditional Framework for Cryptocurrency Contagion and Portfolio Risk

This report introduces a novel conditional framework to address a critical gap in the existing financial literature: the failure to account for the dynamic, state-dependent nature of cryptocurrency market contagion. The analysis moves beyond a static view of cryptocurrencies as either a "safe haven" or a correlated risk asset, arguing instead that their behavior is highly sensitive to traditional market conditions. A core finding is that crypto-market dynamics are driven by a disproportionately large "noise component" and the predictable behavior of uninformed retail investors. This structural immaturity creates a fertile environment for unidirectional spillover effects from traditional markets to intensify during periods of crisis. The report provides a robust, meta-analytical conclusion that reinforces this perspective. Building on these findings, the paper offers actionable recommendations for key stakeholders, including a conditional portfolio strategy for investors and a concrete regulatory roadmap for policymakers, thereby distinguishing its contribution from a standard academic review.
