There is no stopping the growth of government and corporate debt, which reached $109 trillion globally in 2025 from $100 trillion in 2024. However, despite geopolitical tensions and the tariffs war, debt markets have been resilient with moderate volatility and abundant liquidity. "This superficial stability, however, masks deeper structural developments that could suddenly materialise and increase risks if current macro-trends continue," explains Carmine Di Noia, director for financial and enterprise affairs at the OECD, the Organisation for Economic Co-operation and Development in presenting the latest Global Debt Report.

Short deadlines and refinancing risk

As borrowing costs continue to rise, especially on longer maturities, due to the structural decline in demand and concerns about fiscal trajectories, 'governments and corporates are responding by shifting their issuance to shorter maturities, which, while mitigating the impact of rising interest expenses, also exposes them to greater refinancing risk,' Di Noia added.

For the OECD countries alone, outstanding debt now stands at a record $61 trillion, up from $55 trillion in 2024, or 83% of GDP in OECD countries, but expected to rise to 85% in 2026, 39 percentage points higher than in 2007, before the global financial crisis. Much of the increase in lending is for refinancing existing debt. In 2025, sovereign refinancing needs in the OECD reached a record high of about USD 13.5 trillion, accounting for almost 80% of gross issues.

Italy second in debt after Japan but trajectory improving

Among the G7 countries, the international organisation points out, "the debt/GDP ratio remained unchanged with respect to 2020 in Canada, the United States and the United Kingdom. In France and Germany," the OECD continues, "it was respectively 5 and 2 percentage points higher. Italia has the second highest debt-to-GDP ratio in the OECD area, but in 2025 the value was 11 points below the pandemic peak' but what is important 'is to have a credible fiscal trajectory...and I think the Italian economy is doing well,' Di Noia commented

Net needs still above pre-Covid levels

At about USD 3.5 trillion, net requirements remained stable in 2025, but remain substantially above pre-pandemic levels, and are expected to grow in 2026, reaching the highest level since 2020.

Global sovereign and corporate issuance is expected to increase by USD 26 trillion this year.

The corporate market conditioned by IA issues

Corporate debt also increased in 2025 to an all-time high of about USD 36 trillion in bonds and USD 23.1 trillion in syndicated debt for a total of USD 59.5 trillion. Given the amount of capital expenditure required to finance the expansion of AI, it is expected that corporate debt requirements will continue to increase.

In 2025, nine large players commonly known as 'hyperscalers' raised a total of USD 122 billion from the bond markets, accounting for nearly half of all issues by technology companies globally. According to the Global Debt Report, capital expenditure projections indicate that this is only the beginning. These nine companies have projected capital expenditures of $4.1 trillion between 2026 and 2030, about 36% more than the total capital expenditures of all US non-financial companies in 2025. If half of these investments were financed through bond markets, these nine companies would account for 15% of the historical average annual issuance of non-financial corporations globally. These developments could lead corporate debt markets to become more similar to equity markets. With 12% of the global market capitalisation, these nine companies are already a key part of global equity markets.

"Global debt markets have remained resilient and lending has reached record levels, but debt servicing costs are rising and financing needs related to artificial intelligence are soaring," said OECD Secretary-General Mathias Cormann. In order to safeguard stability in the years ahead while meeting growing public and private financing needs,' Cormann emphasised, 'governments must address the risks of volatility generated by changes in the investor base, pursue sound fiscal policies to strengthen debt sustainability, and improve medium-term growth prospects.
