U.S. national debt nears $40 trillion, and Bank of America warns bonds could feel the strain.
What happened
The U.S. national debt is closing in on $40 trillion. Bank of America cautioned that this scale could erode investor confidence and push up the government's borrowing costs. The shift in sentiment moved roughly 500 billion dollars of market value.
Why it matters
Rising borrowing costs for the U.S. government ripple outward: mortgages and corporate loans get more expensive because they are priced off Treasury yields. At the same time, banks and investors holding bonds see the market value of those bonds fall when yields rise. Today's market stress reading is calm, which suggests the fear has not yet spread broadly.
The case against
Corporate credit conditions are actually improving. High-yield bonds are outperforming investment-grade by 0.5 percent, which signals markets are rewarding risk rather than fleeing to safety. The day's market forces are split and the index trended up, showing no clear vote of no-confidence in U.S. debt.
What settles it
Whether the spread between investment-grade and high-yield bonds suddenly widens, signaling a shift from risk-taking to fear over sovereign debt.
