Why ‘Black Monday’ Is Making Headlines Again

On April 4, 2025, global financial markets were rattled by the worst single-day selloff since the COVID-19 pandemic. Over $5 trillion in market value was wiped out within hours, prompting analysts and media outlets alike to draw comparisons to the infamous “Black Monday” crash of 1987. This time, however, the trigger wasn't just economic uncertainty—it was geopolitics.

What Happened?

On that Friday, U.S. President Donald Trump announced sweeping tariffs affecting nearly 180 countries. The move, part of a broader protectionist trade agenda, sparked immediate fears of a deepening global trade war. Investors reacted swiftly. Stock indices across the U.S., Europe, and Asia plummeted. Tech, manufacturing, and logistics companies—most sensitive to international trade policies—led the downturn.

Why ‘Black Monday’?

Historically, “Black Monday” refers to October 19, 1987, when the Dow Jones Industrial Average fell by more than 22% in a single day—a record drop. Fast forward to 2025, and the April 4th crash is being dubbed by some as a “modern Black Monday” due to its massive scale and far-reaching impact.

Why Does It Matter?

The financial world is increasingly interconnected. When markets plunge this dramatically, the ripple effects are felt across industries, continents, and economies. From institutional investors to everyday traders, the panic-induced selloff wiped out gains and triggered a wave of risk-off behavior. Treasury yields dropped, commodity prices shifted, and safe-haven assets like gold surged.

What Now?

Market watchers are closely monitoring how other nations respond to the tariff shock. Will retaliation follow? How will global supply chains adjust? And will central banks intervene to stabilize sentiment?

While the dust is still settling, one thing is clear: the global economy has entered a new phase of uncertainty.
