Global Debt Hits Record $365.5 Trillion After $10 Trillion H1 2026 Surge

The Quick Take

• Global debt climbed by over $10 trillion in H1 2026 to a record $365.5 trillion, led by emerging market borrowing
• The IIF report notes the H1 increase was less than half of the $21 trillion added in H1 2025
• Emerging market debt accumulation is outpacing developed markets, raising sovereign refinancing risk concerns

The Institute of International Finance's latest report reveals that global debt reached a record $365.5 trillion at the midpoint of 2026, reflecting a $10 trillion increase over the first six months of the year. While the H1 pace of accumulation is considerably slower than the $21 trillion surge recorded in the corresponding period of 2025, the aggregate level sets a new historical peak at a time when central banks in developed markets are still executing quantitative tightening and interest rates remain well above historical norms. The primary driver of H1 2026 accumulation is emerging market borrowing, as governments across Africa, Southeast Asia and Latin America tap debt markets to finance fiscal deficits and infrastructure programmes.

At $365.5 trillion—roughly 330% of global GDP—the debt-to-GDP ratio signals that the global economy's debt-servicing burden will remain a structural constraint on growth and monetary policy flexibility for the foreseeable future. UAE-domiciled sovereign wealth funds and GCC investors are significant holders of emerging market debt and face mark-to-market pressure if sovereign spreads widen. The IIF data reinforces the case for extended higher-for-longer interest rates in developed markets, as the sheer volume of debt refinancing that must occur over the next three years creates an immovable demand for risk-free rate relief.

The critical watch point is the pace of emerging market debt maturity walls over 2027–2029, during which a large cohort of bonds issued at low pandemic-era rates must be refinanced at significantly higher current market rates. Countries with elevated primary deficits and limited foreign exchange reserves—including several sub-Saharan African and South Asian sovereigns—face the highest refinancing risk. The macro variable is the US dollar trajectory: dollar strength dramatically increases the debt-servicing cost for emerging market borrowers with USD-denominated liabilities, while dollar weakness in a soft-landing scenario provides material relief across EM sovereign balance sheets.
