AI Summary. An analysis of 22 rich countries estimates that if each refinanced its entire debt at current five-year bond yields, Britain would need the largest primary surplus to stabilize its debt-to-GDP ratio, about 1.5%, followed by Italy at 1.4%, France at 1.2% and America at 1%.

Refinancing the entire US debt stock at the current five-year borrowing rate, on current growth forecasts, would require a primary surplus of 1% of GDP to hold the debt ratio stable, a fiscal consolidation of 4.7pp. In October 2025, it would have required 2.3pp.

How much belt tightening would rich countries need to stabilize debt?

Core argument: The Economist calculates that Britain would need the largest primary surplus of 22 rich countries, about 1.5% of GDP, to hold its debt-to-GDP ratio stable if it replaced its entire debt stock at today’s five-year yields.

The Economist calculated what would happen if rich countries had to replace their entire debt stocks at today’s five-year bond yields, using IMF forecasts for nominal growth. Out of 22 countries, Britain would need to run the largest primary surplus, of about 1.5% of GDP, merely to keep its debt-to-GDP ratio stable. Italy and France are next, needing surpluses of 1.4% and 1.2%, respectively. America is not far behind, requiring one of 1%. Japan can run a deficit of 0.8% since its growth is estimated to outpace the interest rate on its debt. America is running a primary deficit of nearly 4% of GDP, meaning significant belt tightening of nearly five percentage points of GDP is needed to stabilise its debt ratio at today’s borrowing costs. The situation is deteriorating fast as a result of persistent deficits and surging yields. Just a year ago America required an adjustment of more than two percentage points less than it does today.

Takeaways by Macro Roundup® AI

  1. The Economist calculates that Britain would need the largest primary surplus of 22 rich countries, about 1.5% of GDP, to hold its debt-to-GDP ratio stable if it replaced its entire debt stock at today’s five-year yields.
  2. America requires a primary surplus of 1% of GDP to stabilise its debt ratio at today’s borrowing costs while running a primary deficit of nearly 4%, implying belt tightening of nearly five percentage points of GDP, by The Economist’s calculation.
  3. Japan can run a primary deficit of 0.8% of GDP and still keep its debt burden stable because its growth is estimated to outpace the interest rate on its debt, while Italy and France need surpluses of 1.4% and 1.2%.

  • America’s Risky Debt: What Markets See That Policymakers Don’t — Two market-based measures suggest the safety premium investors pay to hold US Treasuries has compressed toward zero and at times reversed: the spread between top-rated corporate bonds and Treasuries after stripping out default risk, and the gap between currency-hedged foreign G10 government yields and Treasury yields at the same maturity, where longer-maturity comparisons now favor foreign bonds.
  • The United States Capital Structure — Because Social Security and Medicare benefits are politically untouchable, retirees effectively hold the most senior claim on US government resources while Treasury bondholders hold the riskiest one. On this argument, bondholders absorb adverse fiscal shocks through surprise inflation, financial repression, or both.
  • How Might Fiscal Policy Respond to the Rise of Artificial Intelligence? — The Congressional Budget Office estimates that a permanent 0.5 percentage point increase in annual productivity growth would lower publicly held federal debt after 30 years by 39% of GDP, offsetting roughly half the projected rise from 101% of GDP to 175%. Higher revenue and slower spending growth outweigh higher interest costs.
