How much will maturing advanced-economy government debt cost to refinance?
Core argument: About 60% of OECD fixed-rate debt maturing by 2027 — roughly $9tn — was issued in 2021 or earlier, and with weighted average yield-to-maturity below 2% in 2025–27 against projected 10-year rates near 3.6%, it will likely be refinanced at nearly twice original rates.
Around 60% of the fixed-rate debt in the OECD that will mature by 2027 (approximately $9T) was issued in 2021 or earlier, before the recent tightening cycle, most likely at yields below current market rates. The weighted average YTM of the maturing debt in 2025-27, remains below 2% in all three years, [while] the average of the projected 10-year interest rate in OECD countries is expected to remain around 3.6% in 2025. The debt maturing in 2025-27 will, therefore, likely be refinanced at nearly twice the original rates. Increased borrowing needs and high borrowing costs have driven interest payments to a higher share of GDP in 2024, [contributing to] the first increase in the central government marketable debt-to-GDP ratio since 2020. The supply of bonds needing to be absorbed by the market accelerated as central banks continued to scale back their holdings. Four countries — France, Spain, the United Kingdom, and the United States — face heightened vulnerability, with the debt maturing by 2027 exceeding 15% of their current GDP and the average yield-to-maturity on debt issued in 2024 surpassing that of this maturing debt by over 1.5 percentage points.
