US National Debt Nears $40 Trillion as Corporate Bond Issuance Surges

The US national debt has climbed to approximately $39.9 trillion as of mid-August 2026, nearing the $40 trillion milestone. With new debt accumulating at a rate of $7 to $12 billion daily, this threshold is expected to be crossed shortly. The Congressional Budget Office (CBO) anticipates that the debt-to-GDP ratio will reach 120% by 2036, raising concerns about the dollar's status as the world’s reserve currency.

In parallel, corporate bond issuance in the US has surged to $1.681 trillion year-to-date through July 2026, marking a 26.9% increase compared to the previous year. Major corporations, particularly in technology and utilities, are aggressively tapping into the bond markets to fund capital expenditures, particularly related to artificial intelligence infrastructure.

The second quarter of 2026 saw a record $605 billion in investment-grade corporate bond issuance, a 42% increase from the same period last year. However, investor caution is growing, particularly as technology-sector spreads begin to widen, indicating potential market fatigue.

As the market approaches a potential record year for corporate bond issuance, analysts are closely monitoring new-issue concessions, which could signal shifts in investor sentiment and demand dynamics.
