Quick Answer
Global debt hit a new all-time record of nearly $353 trillion by the end of March 2026, according to the Institute of International Finance, with $4.4 trillion added in the first quarter alone — the fastest quarterly pace since mid-2025 and the fifth consecutive quarterly rise. Separately, the OECD’s 2026 Global Debt Report shows governments and companies are set to borrow a record $29 trillion from bond markets in 2026, 17% more than in 2024, with sovereign bond debt in OECD countries having reached an all-time high of $61 trillion in 2025. The IMF’s Fiscal Monitor projects gross global debt will reach 100% of global GDP by 2029 — one year earlier than the Fund had previously estimated — while JPMorgan CEO Jamie Dimon has warned of the possibility of “some kind of bond crisis” if the trajectory isn’t addressed proactively.
The Headline Numbers, From Multiple Sources
It’s worth noting that different institutions measure “global debt” somewhat differently, which explains why headline figures vary across sources even when describing the same underlying trend. Catenaa’s May 2026 reporting on Institute of International Finance data puts total global debt at nearly $353 trillion as of Q1 2026, driven primarily by the US and China as the two biggest contributors to the increase. A separate IMF Global Debt Database-based analysis from Recession Today puts the figure somewhat lower, at $310 trillion in early 2026 — still up from $305 trillion at the end of 2024 and substantially above the $225 trillion recorded in 2019, before the pandemic. Both figures, despite their different scope and methodology, tell the same underlying story: a debt load that has grown dramatically over the past several years and shows no sign of plateauing.

The Bond Market Specifically Is Under Real Strain
The OECD’s 2026 Global Debt Report, published in March 2026, provides granular detail on the sovereign bond market side of the story specifically. Refinancing requirements — money governments need to raise simply to replace maturing existing debt, rather than new borrowing — hit a new high of around $13.5 trillion in 2025, accounting for nearly 80% of total gross borrowing. Net new borrowing, by contrast, remained stable in 2025 but is projected to climb to nearly $4 trillion in 2026, the second-highest level on record. Outstanding sovereign bond debt across OECD countries reached an all-time high of $61 trillion in 2025, up from $55 trillion in 2024 — the largest annual increase since the pandemic, partly driven by US dollar depreciation, which mechanically inflates the dollar value of debt denominated in other currencies when converted for comparison.
Interest Costs Are Rising Even Faster Than Debt Itself
Perhaps the more concerning dynamic isn’t the debt stock itself, but how much it now costs to service. The IMF’s Fiscal Monitor, summarized by the Committee for a Responsible Federal Budget, shows global interest payments are now nearly 3% of global GDP, up from just 2% four years earlier — a meaningful jump in a relatively short window. The IMF identifies a specific mechanical driver behind this acceleration: as US and other advanced-economy debt rises, investors are less willing to accept lower returns on Treasuries, meaning the “safety premium” on government debt decreases. Since Treasuries function as the effective benchmark for “risk-free” investments globally, that declining safety premium raises interest rates across the entire global financial system, not just for the US specifically. Compounding the issue, there’s been a notable shift toward shorter-term debt issuance — roughly 33% of US debt will roll over within the next year alone — which the IMF notes has caused debt service costs to skyrocket, with net interest payments having doubled between 2022 and 2025 and on track to double again by 2034 if current trends continue.
The Refinancing Wall Facing 2026-2028
Catenaa’s reporting flags a specific, concrete near-term risk worth understanding directly: emerging markets face more than $9 trillion in debt maturities in 2026 alone, while advanced economies must refinance over $20 trillion in bonds and loans over the same period — a genuinely heavy refinancing burden landing in an already fragile rate environment. Recession Today’s analysis adds further granularity on the emerging-market side specifically: over $3.5 trillion in emerging-market sovereign debt will mature in 2026-2028, requiring refinancing at rates significantly higher than the original issuance terms, while the IMF’s debt-service ratio for emerging markets — interest and principal payments as a share of export revenues — has risen to 18.5%, a level historically associated with increased default risk. Approximately 30% of emerging-market government debt is denominated in foreign currency, according to the same analysis, creating additional vulnerability to exchange-rate depreciation on top of the refinancing risk itself.

What Dimon and the OECD Are Warning About
JPMorgan CEO Jamie Dimon’s warning, cited by Catenaa, is notably direct: “there will be some kind of bond crisis,” he said, adding, “I just think the prudent thing is to deal with it rather than let it happen.” His stated concerns span a cluster of interacting risks — geopolitical tensions, oil price volatility, and widening budget deficits — while he acknowledged the timing of any potential crisis is impossible to predict with precision. The OECD’s report strikes a similarly cautious tone about complacency specifically: “the current favorable liquidity environment should not breed complacency about structural vulnerabilities in market microstructure,” the report states, according to Libertify’s summary — a warning that debt markets have absorbed a series of shocks in recent years without breaking, but that resilience shouldn’t be assumed to persist indefinitely.
Not All Emerging Markets Are Equally at Risk
It’s worth noting the OECD’s data doesn’t paint a uniformly grim picture across all emerging markets. The report notes some genuinely positive developments: sovereign bond spreads in certain larger emerging-market economies actually tightened during 2025, reflecting improved market confidence in their fiscal management and institutional frameworks. However, this aggregate improvement masks significant dispersion — countries with weaker institutional frameworks, heavy commodity dependence, or political instability face substantially higher borrowing costs and more limited market access, and the gap between the strongest and weakest emerging-market borrowers has widened, creating what the report describes as an increasingly bifurcated emerging-market debt landscape requiring differentiated policy responses rather than a one-size-fits-all approach.
Frequently Asked Questions
How much is global debt in 2026?
Estimates vary by methodology: the Institute of International Finance puts global debt at nearly $353 trillion as of Q1 2026, while an IMF Global Debt Database-based analysis puts it closer to $310 trillion in early 2026.
When will global debt reach 100% of GDP?
The IMF’s Fiscal Monitor projects gross global debt will reach 100% of global GDP by 2029, one year earlier than the Fund’s previous estimate.
How much sovereign debt needs to be refinanced in 2026?
Advanced economies must refinance over $20 trillion in bonds and loans, while emerging markets face more than $9 trillion in debt maturities in 2026 alone.
Is a global bond crisis likely in the near term?
JPMorgan CEO Jamie Dimon has warned “there will be some kind of bond crisis” given current debt trends, though he acknowledged the specific timing is impossible to predict, and the OECD notes debt markets have so far absorbed several shocks without breaking.
