The Institute of International Finance (IIF) reported that global debt exceeded $365 trillion in the first half of 2026, with emerging markets accounting for most of the increase. That is a record-sized all-sector debt stock, but it is not, by itself, a measure of how close borrowers are to default. Borrowing costs, repayment capacity and which sectors owe the debt matter too. The IIF’s September 23, 2026 monitor is the source of the debt figures; the available reporting does not establish a direct statement by the IIF CEO about this release.
What the IIF’s latest Global Debt Monitor says
The IIF’s September 23, 2026 monitor put global debt above $365 trillion in the first half of 2026. The total covers government, household, financial-company and non-financial-company debt across more than 100 mature and emerging economies, according to contemporaneous reporting on the monitor.

The same reporting describes the first-half increase as more than $10 trillion, but less than half of the $21 trillion added in the first half of 2025. So the stock continued to grow rapidly, while the pace of accumulation was slower than a year earlier. Emerging markets accounted for the bulk of the H1 2026 rise.
These are nominal dollar amounts: they describe the outstanding stock of debt, not the amount borrowers must pay this year. Nor does the global total show how debt is distributed among countries, sectors or individual borrowers.

Why the debt stock and debt ratio can tell different stories
The IIF said higher inflation helped contain debt ratios even as the nominal debt stock grew. A debt-to-GDP ratio compares debt with the value of economic output. If nominal GDP rises, including because prices rise, that denominator can grow enough to moderate the ratio without reducing the amount owed.
A moderated ratio therefore does not mean the debt stock fell or repayment became easier. Inflation can raise nominal incomes and tax receipts, but it can also increase costs and borrowing rates. The effect on a particular borrower depends on factors such as income growth, interest rates, currency exposure and when the debt must be repaid.

Keep the IMF government-debt figures separate
The IIF’s figure above $365 trillion is a dollar total spanning government, household and corporate borrowers. It should not be confused with the International Monetary Fund’s (IMF) government-debt measure, which compares public debt with GDP.
In its April 2026 Fiscal Monitor, the IMF reported global gross government debt at nearly 94% of GDP in 2025 and projected it would reach 100% of GDP by 2029 on current trajectories. Those figures refer to government debt as a share of global GDP—not to the IIF’s all-sector dollar stock. The two measures answer different questions and cannot be directly compared as if they were competing estimates of the same total.
Why debt-service costs matter to borrowers and governments
A large debt stock becomes more difficult to manage when interest costs absorb more of a borrower’s income or revenue. The IMF’s April 2026 analysis identifies elevated borrowing costs and debt-service burdens as constraints on governments’ fiscal room. It also says interest payments in the world’s poorest countries have reached historically high levels relative to revenue.
For governments, higher interest bills can leave less revenue for public services, investment or responses to economic shocks. For households and businesses, the equivalent concern is whether debt payments remain affordable as rates, income or expenses change. A global headline cannot establish that answer for an individual country or borrower: debt terms, maturities, currencies and revenue sources differ.

How to read a global debt headline
- Check what is counted. The IIF total includes government, household, financial and non-financial corporate debt. A public-debt figure covers a narrower borrower group.
- Check the unit. A dollar stock measures the amount outstanding; a debt-to-GDP ratio relates debt to economic output; interest payments relative to government revenue indicate how much income is going to service public debt.
- Check the period and comparison. The IIF’s H1 2026 increase exceeded $10 trillion but was less than half the $21 trillion increase in H1 2025, as reported contemporaneously. A slower increase is not a decline in debt.
- Check who is borrowing and where. Emerging markets accounted for most of the IIF-reported increase, but that does not mean every emerging-market country faces the same risks.
- Look beyond the headline stock. Borrowing costs and debt-service burdens help show whether payments are crowding out other spending or becoming harder to meet.
What the figures mean for personal finances
The IIF’s global total is context, not a forecast for household interest rates, inflation or investment returns. It does not show how much any one government will borrow, whether a central bank will change rates, or how a particular family’s finances will fare. For personal decisions, use information that applies to your own country and loan: the interest rate, whether it is fixed or variable, payment schedule, currency and the income available to cover repayments.
The broader lesson is to distinguish the size of debt from its cost and affordability. A rising global stock warrants attention, but the change in the stock, the borrowers involved and the burden of servicing it are all needed to assess risk.
