The $348 trillion ledger
Private and public debt set a record in 2025. Sovereign debt is heading back to 100% of world GDP — earlier than the IMF thought.

A record that is easy to shrug at, and shouldn’t be
The Institute of International Finance counted nearly $29 trillion of new debt in 2025, taking the global stock — public plus private, non-financial — to about $348 trillion. The IMF’s April 2026 Fiscal Monitor is the sovereign slice: world government debt just under 94% of GDP in 2025, on course for 100% by 2029, a year earlier than previously projected, ‘driven overwhelmingly by high debt in the United States and China’. After the pandemic spike, the world did not retrace. It plateaued on a high ledge and started climbing again.
Advanced and emerging have swapped scripts
For decades the morality play was simple: rich countries can carry debt, poor ones cannot. Emerging-market public debt is now around 77% of GDP and still rising. Advanced-economy debt never came back to the pre-GFC 70s. Japan remains the extreme; the United States is the systemic one, because the dollar is the unit the rest of the ledger is written in. China’s local-government and property complex is the other systemic one, because it is large, opaque, and already being rolled, not resolved.
The cost of the ledge
When real rates were zero, 90% of GDP was a number. When they are not, it is an interest bill that crowds defence, climate and aging — the three other charts in this issue. That is the long view: debt is not a separate theme. It is the constraint on every other theme. A world that wants to rearm, rebuild grids, and pay for 65+ will find the bond market has a veto, even if that veto arrives as inflation and financial repression rather than a textbook crisis.
How this changes an investment map
Duration is a regime choice, not a personality. Quality cash-flow assets with pricing power fare better than levered hopes. Hard collateral (see gold) becomes insurance, not a religion. Fiscal beneficiaries — infrastructure with contracted returns, defence with appropriations — can coexist with a heavier sovereign, until they cannot. The honest stance is barbell: some insurance, some real assets, less faith that the 2010s will be rerun.
Investing lens
Horizon 3–10 years · Educational, not advice
Treat the sovereign as a competitor for capital, not a free put. Favour issuers and equities that can live with higher-for-longer real rates; hold some non-sovereign stores of value; be selective in duration.
Where the map points
- Short-to-intermediate high-quality duration rather than blind long bonds
- Inflation-linked issuance where the sovereign is credible
- Gold and, for a smaller sleeve, scarce real assets as policy insurance
- Equities with low refinancing need and pricing power
What can break it
- Financial repression can punish the insurance trade for years
- A growth shock can make this year’s ‘too much debt’ into next year’s rally in bonds
- Emerging-market debt crises are uneven — the index hides the country
