Japan's bond market turmoil this week has sparked serious conversations at major financial forums. Market participants are asking a pressing question: how much longer before speculators turn their attention to America's massive debt burden?

US Treasury Secretary Scott Bessent's description of the US debt as a "mountain" isn't just colorful language—it's a reality check. With global markets already stressed over Japan's situation, the question of when (not if) market vigilantes might challenge US fiscal policy is becoming increasingly urgent. The parallels are hard to ignore: rising yields, market volatility, and a growing skepticism about sustainability.

For those tracking financial markets and macro trends, this is more than headline noise. It's a reminder that debt dynamics shape the broader investment landscape, including sentiment in risk assets.
