The US’s massive debt pile is fueling the bond-market crash. These 4 charts tell the story.

• The US’s ballooning debt burden is sparking concern on Wall Street.
• The country is one of just 21 worldwide whose debt-to-GDP ratio exceeds 100%.
• Concerns about deteriorating public finances have contributed to a meltdown in Treasury-bond prices the past few weeks.

The Treasury-bond rout that’s rattled US markets this month is forcing investors to zero in on the government’s spiraling debt.

The accelerated increase in America’s indebtedness has already sparked concern for investors in 2023, with lawmakers only narrowly avoiding a catastrophic default in June thanks to President Joe Biden and then-House Speaker Kevin McCarthy brokering an 11th-hour deal to raise the federal borrowing limit.
