IMF warns global debt is surging—Russia’s bill rises, Italy’s deficit tightens, and US Treasuries lose their edge

The IMF is warning that global public debt is climbing rapidly, reaching 94% of global GDP in 2025 and projected to hit 100% by 2029. In parallel, the Fund lowered its forecast for Russia’s public debt growth, projecting it at 19.1% of GDP by end-2026, while another report cites a rise to 29.1% by 2031. The IMF also cautioned that prolonged war dynamics can push sovereign debt trajectories sharply higher, with a severe scenario pointing to global debt exploding toward 120% of global GDP. Separately, the IMF flagged that broad fuel subsidies are a risky policy response to war-driven energy shocks, urging countries to avoid measures that worsen fiscal stress and distort markets. This cluster matters geopolitically because it links conflict-driven energy disruption and sustained defense spending to fiscal sustainability, tightening the room for maneuver for governments under pressure. The power dynamic is shifting from “growth-funded” fiscal expansion toward “market-funded” financing, where investor demand and term premia become decisive constraints—especially for large issuers. Russia’s debt path, even if currently contained in the near term, is still portrayed as structurally upward over the medium term, reflecting the fiscal burden of a long conflict environment. Italy’s outlook underscores how European consolidation and productivity narratives are being tested by debt arithmetic, while the IMF’s warning to the US highlights how even the world’s benchmark issuer can face changing investor pricing as issuance scales. Market and economic implications are immediate for sovereign bond investors and for cross-asset risk appetite. The Bloomberg-reported IMF message that Treasuries are losing their premium implies upward pressure on yields and a potential repricing of duration risk across global government securities, not just in the US. Italy’s projected deficit decline to 2.8% in 2026 alongside debt rising to 138.4% signals continued supply and refinancing needs, which can keep Italian spreads sensitive to risk-off episodes. For energy policy, the IMF’s stance against broad fuel subsidies suggests that countries may pivot toward targeted support or tax/price mechanisms, affecting fuel demand, inflation expectations, and the outlook for oil-linked cash flows. For Russia, the debt ratio forecasts imply that fiscal stress is not the dominant near-term driver of macro instability, but the medium-term trajectory increases the probability of future funding pressure. What to watch next is whether governments adjust financing plans and energy support design in response to the IMF’s warnings. Key indicators include the pace of US Treasury issuance, auction tail behavior, and changes in term premia that would confirm the “premium erosion” thesis. In Europe, investors will watch Italy’s fiscal consolidation steps tied to the NRRP and whether the debt-to-GDP path stabilizes as projected. For Russia, the trigger is not the 2026 level itself but any deviation that accelerates the path toward the 2031 estimate, including changes in budget balance or external financing conditions. Finally, the energy-policy trigger is whether countries move away from broad fuel subsidies toward targeted measures without reigniting inflation or social unrest, which would feed back into sovereign risk premia.

Geopolitical Implications

• 01

  Conflict-driven energy shocks are translating into fiscal constraints that tighten sovereign financing conditions.

• 02

  Investor pricing power may shift as US issuance scales, potentially propagating repricing across global rates.

• 03

  Europe’s debt arithmetic remains fragile even when deficits improve, increasing sensitivity to political and market shocks.

• 04

  Russia’s medium-term debt trajectory suggests sustained fiscal burdens from prolonged conflict.

• 05

  Energy subsidy design is becoming a geopolitical-economic lever that can amplify or contain sovereign risk premia.
