Global Debt Service Costs Soar to 3.3% of GDP, Highest Since 2007

There’s a quiet budget crisis that’s hiding in America’s bill — and interest costs are to blame. According to the OECD’s Global Debt report, nations are now funneling 3.3% of their GDP toward debt service costs, outpacing defense spending and reaching levels not seen since before the 2008 financial crisis. This burden comes as wealthy nations are facing a borrowing binge, with anticipated issuance reaching a record $17T in 2025.
- Nearly 45% of OECD sovereign debt will mature by 2027, forcing governments to refinance trillions in bonds at significantly higher rates than when originally issued.
- The US leads with interest costs consuming 4.7% of GDP, followed by Italy at 4.1% — while, contrastingly, Germany maintains a mere 1% ratio.
Balancing act ahead: Germany’s modest debt burden has given it room to act — pushing through a trillion-euro defense and infrastructure package that could offer a blueprint for others. The plan aims to stimulate growth and reduce reliance on the US, all while staying fiscally grounded. But sustaining this path won’t be easy. As central banks retreat from emergency bond-buying, more price-sensitive private investors will need to fill a $4T gap by 2025. OECD’s Carmine Di Noia emphasized that large debt itself isn’t inherently problematic, but cautioned that “borrowing must increase growth” to stabilize and reduce debt-to-GDP ratios.
