The era of ultralow interest rates has ended, triggering a rapid readjustment for global markets. Long-term government debt yields hit their highest level in nearly 20 years, fueled by persistent inflation, geopolitical tensions, heavy artificial intelligence borrowing, and fiscal strain. National debt recently exceeded $40 trillion, heightening long-term sustainability concerns across investors.

Experts emphasize that recent decades featured historically abnormal rate declines following the 2008 crisis. Current figures merely reverse that prolonged drop, returning to levels once considered modest. Yet the broader economy has fundamentally changed since rates last stood this high.

Institutions and households structurally adapted to cheap capital, making elevated borrowing costs notably more burdensome now. This environment complicates the President’s affordability agenda, as mortgage and consumer loan rates climb despite political pressure. With inflation entrenched, the Federal Reserve cannot easily cut short-term rates, leaving long-term market dynamics to dictate broader financial conditions and everyday household budgets worldwide.
