Big Tech’s AI debt binge is colliding with a $3.6 trillion refinancing wall

Big Tech’s AI debt binge is colliding with a $3.6 trillion refinancing wall across the US and global system as old cheap money turns into expensive refinancing pressure.

The tech sector is sitting on more than $330 billion in high-yield, leveraged loan, and business development company-linked software and technology debt that must mature through 2028. This stack was built in a low-rate era. Now rates are higher, and the math has flipped fast.

A large chunk lands in 2028 alone. About $142 billion matures that year, almost three times the 2026 level. Inside that 2028 wave, roughly $65 billion sits in high-yield bonds and about $77 billion in leveraged loans. Most of this debt was issued when interest rates were near zero during the pandemic. 

That setup is gone. Many companies are already lining up refinancing moves as early as the second half of this year, and the sector is heading into a higher interest rate environment that will reset funding costs across tech balance sheets.

Tech companies begin refinancing pandemic-era debt

The refinancing pressure is not small. More than $330 billion in tech-linked debt is rolling into maturity through 2028, and the 2028 spike of $142 billion stands out as the main pressure point. Companies that locked in ultra-cheap money during the pandemic now face significantly higher borrowing costs when they roll debt forward.

The timing matters. A wave of refinancing is expected to start in the second half of this year, which means the repricing cycle is not years away. It is already starting.

The tech sector, especially software-heavy borrowers tied to high-yield bonds and leveraged loans, is moving from near-zero interest rate financing into a tighter credit regime where every rollover comes at a higher cost. This shift is not isolated. It sits inside a broader global debt squeeze that is hitting both corporate and sovereign borrowers at the same time.

Global debt pressures rise as IMF flags 99% world GDP debt load and US fiscal trajectory climbs toward 142%

The International Monetary Fund mapped a wider stress line across global finances. Global public debt is projected to reach 99% of world GDP by 2028, with scenarios pushing it to 121% under stress cases within three years.

The United States remains a central case, with $39 trillion in national debt and a deficit expected to sit around 7.5% of GDP after a short improvement that faded.

US debt is on track to pass 125% of GDP this year and could reach 142% by 2031. The adjustment needed just to stabilize that path, not reduce it, would require about 4% of GDP in fiscal tightening. Markets are already shifting.

The premium on US Treasuries compared to other advanced debt is shrinking. One IMF fiscal official said, “These are signs that markets are not as sanguine, as forgiving, as they were in the past. This cannot wait forever.”

The fiscal gap has also widened by about one percentage point compared to pre-COVID levels. The IMF linked this to policy choices, not short-term cycles, pointing to higher spending and lower revenues as the base driver.

Real interest rates are now about six percentage points above pre-pandemic levels, adding pressure to every layer of existing debt.

Energy policy is also feeding into the strain. The IMF warned that broad subsidies distort pricing and strain budgets, with one official saying, “They distort price signals, are fiscally costly, regressive, and hard to unwind.”

When many countries shield consumers, the rest absorb the adjustment, with spillover effects that can double price shocks for those not using subsidies.

Fiscal Monitor’s Era Dabla-Norris noted governments have been more restrained than during the 2022 energy crisis, but said fiscal space is now tighter, making old-style support far more expensive.
