IMF opens its Bangkok meetings warning that global public debt will exceed 100% of output before 2030
Kristalina Georgieva, the IMF's managing director, warned that "winter is coming," as interest payments already take more than a tenth of revenue in the average developing country and the Iran war's energy shock leads the agenda.
The annual meetings of the International Monetary Fund (IMF) and the World Bank opened in Bangkok on October 12 and run for seven days. Thai business leaders are using them to seek foreign investment. Nikkei Asia listed inflation, artificial intelligence and climate as the main themes, but the energy shock from the war with Iran is the issue finance ministers arrived to discuss.
Georgieva set the tone in her opening speech, telling delegates that "winter is coming." The IMF says global public debt is at its highest level since the Second World War and will exceed 100% of world gross domestic product (GDP) before 2030. In developing countries, interest payments already exceed 10% of government revenue on average, and much of that debt will have to be refinanced at higher rates.
Research for the Financial Times finds that major economies are absorbing the Iran shock so far, but identifies "worrying omens," led by rising public debt. The two findings are consistent. Growth has held up because governments kept borrowing, and that borrowing is now the main risk.
From an Austrian view, the IMF is describing the end stage of a long credit expansion. Public debt has risen in each crisis since 2008 and has not fallen in the recoveries between them. Each energy or war shock now arrives when governments have less room to absorb it, and they rely more on central banks to keep their borrowing costs down.

The Long-End Revolt
Governments will keep reaching for balance-sheet tools to suppress long-term yields, and bond markets will keep repricing duration higher anyway, so each intervention transfers demand into scarce assets instead of lowering borrowing costs.
What this means
When a government must refinance debt equal to the size of its entire economy at higher interest rates, its interest bill grows faster than its tax revenue. The usual response is pressure on the central bank to buy long-dated bonds or to tolerate higher inflation. Holders of long-dated government bonds in heavily indebted countries face the greatest exposure, and scarce assets such as gold benefit from the policy response markets expect. The consensus view treats these meetings mainly as a forum for warnings. The more significant point is that the IMF has now set a specific date, 2030, by which the global debt ratio crosses 100% of output. The more likely outcome is that over the next several months more finance ministries shorten the maturity of their borrowing and more central banks hint at supporting bond markets, while long-term yields keep rising. This forecast depends on oil staying above $100. It would be proven wrong if long-term yields in the major economies fall steadily while energy prices remain high, which would show that bond buyers still accept current debt levels.
What to watch
- Any communiqué language from the meetings on debt restructuring for developing countries. Concrete terms would show that creditors expect defaults rather than recoveries.
- Long-term government bond auctions in the United States, Britain and Japan in the coming weeks. Weak demand would confirm that buyers want higher yields to hold more debt.
- Statements by central bankers at the meetings on buying government bonds. Any opening toward new purchases would show fiscal needs starting to drive monetary policy.

With the dollar index near an 18 month high, governments that borrowed in dollars face rising debt service in local currency, so the 10% interest to revenue average is more likely to rise than fall.
