Global debt climbed by $10 trillion in the first half of this year, pushing the total past $365 trillion, according to research published by the Institute of International Finance. Economists are warning that the world’s biggest economies are now trapped in what the IIF calls a “vicious cycle” of borrowing, rising costs, and political inaction.
Why Borrowing Is Getting More Expensive
State debts are climbing just as bond yields on medium- and long-term government debt hit their highest levels in more than a decade across several major economies – including the US, Japan, France, and the UK. Those rising yields reflect investor unease over increasing interest rates, persistent energy costs, sluggish economic growth, and heavy government spending.
The IIF singled out these four economies specifically, warning they now face “persistently large deficits and rising interest expenses challenges long associated with debt-distressed emerging market sovereigns.” In other words, problems once considered typical of struggling developing economies are now showing up in some of the world’s wealthiest nations.
A Number That Puts the Crisis in Perspective
The scale here is genuinely striking. Advanced economies paid more than $3.3 trillion in interest on internationally traded government bonds last year alone – more than the world spent on AI ($2.6 trillion), defense ($3.1 trillion), or clean energy ($2.3 trillion), combined categories that dominate global economic conversation.
A Problem Politicians Keep Deferring
The IIF describes debt as having become a deeply political issue, creating what it calls a “vicious cycle between elections and short-term quick fixes,” even as the long-term value of taking on more debt keeps shrinking. As benchmark interest rates climb, the group warns that interest costs are set to surge further, while deeper structural pressures – particularly healthcare and public pension spending – remain largely unaddressed by most governments.
International Bodies Are Sounding the Alarm Together
The Organisation for Economic Co-operation and Development (OECD) in its recent report echoed similar concerns in its economic outlook, arguing that rising bond yields make clear the need for governments to contain and reallocate spending, improve public-sector efficiency, and strengthen revenue streams. The organization called for reforms to ensure debt remains sustainable over the long term and that governments retain the flexibility to respond to future economic shocks.
IMF chief Kristalina Georgieva delivered perhaps the sharpest warning yet, telling the BBC this week that global economic shocks are “pushing debt levels up like a staircase not to heaven,” while criticizing the broader lack of government action. Her prescription is direct: bring debt levels down, prioritize fiscal consolidation, and ensure central banks stay focused on their core mandate of price stability.
Georgieva stressed that it’s hard to overstate just how critical it is for leaders to find the courage to act, acknowledging that the necessary steps are politically difficult, but unavoidable all the same.
