Tariffs, Turbulence, and Factor Fallout: Navigating Global Market Risk with Bloomberg’s MAC3 Models
In early April 2025, sweeping new U.S. tariff policies triggered a dramatic shift in global trade dynamics, sparking heightened volatility and sharp declines across global equity markets. As geopolitical tensions rise and retaliatory measures loom, understanding the ripple effects across style, industry, and country exposures has become mission-critical for institutional investors.

This webinar will explore the systemic shocks unleashed by “Liberation Day,” identify which equity factors suffered or outperformed, and demonstrate how advanced risk models provide critical transparency and actionable insights during periods of macro-driven uncertainty.
