Shorter maturities carry the G7's higher yields into budgets faster, the IMF finds
IMF fiscal chief Rodrigo Valdes says public debt is poised to hit 100% of GDP, the highest since World War Two, as G7 10-year yields climbed over 1 point. Nearly 30% of G7 and Spanish debt matures within a year. Investors should keep borrowing costs and fiscal risk in their planning.
The Investor · Invest desk
G7 and Spain debt maturing within one year is approaching 30 per cent. The G7 average 10-year yield rose over 110 basis points from February to September. The IMF projects the effective cost of government financing at 3.7 per cent by 2031, from 2.3 per cent in 2021.
| Figure | Value | Note | Claim |
|---|---|---|---|
| G7 and Spain debt due within one year, approaching | 30% | 6 | |
| G7 10-year yield rise, over | 110 basis points | 2 | |
| Projected effective cost of government financing, 2031 | 3.7% | up from 2.3 per cent in 2021 | 10 |
What happened
- Valdes said most countries are looking at spending more instead of tightening their belts.
- US interest payments are expected to reach 5.3% of GDP, against 2.8% before COVID, roughly equal to projected Social Security spending.
- In low-income countries interest now takes over 15% of tax revenues, compared with an average of around 9% from 2011 to 2019.
Why it matters
- What it limits constraint With central banks likely to hold rates higher for longer, governments have less room to answer a downturn just as defense, energy security and ageing demands build.
- Who's exposed exposure Emerging-market borrowers still have favorable financing, but the IMF warns it might not last, so they face the repricing the G7 has already absorbed.
- Who has to decide decision An investor holding sovereign or sovereign-sensitive assets has to model refinancing dates and not only yield levels, because the share of debt rolling in the next twelve months sets how fast a rate move reaches budgets.

Georgieva says growth cannot cut US debt of more than $40 trillion fast enoughConfirmed2 publishers
Take the slowest-looking number first. The IMF projects the effective cost of government financing rising 1.4 points between 2021 and 2031 [17]. That looks like a gentle slope, and the maturity profile can make it steeper. Debt due within a year is approaching 30% of the stock in the G7 and Spain [6].
Suppose that slice reprices by the full 1.1 points that G7 10-year yields added between February and September [2] (the SCMP's account of the same IMF blog says more than 1 percentage point [3], which is consistent). One year's rollover then lifts average cost by up to about 0.33 points [18], close to a quarter of the decade's projected rise [19]. This is an upper-end illustration. It assumes short-dated yields moved as far as 10-year yields, and neither report says they did.
Valdes gave the direction of travel to Reuters ahead of the IMF and World Bank meetings in Bangkok [9]. "The fiscal results this year are worse than expected six months ago, and worse than they were one year ago," he said [4]. In an IMF blog post, he and deputy head Era Dabla-Norris wrote: "Higher borrowing costs are adding to fiscal pressures at a time of high debt, making credible consolidation more urgent" [7]. On the way out, Valdes was blunter: "This is unfortunately like the gravity law. There's no way out of the fiscal dynamics here" [8].
In our view the refinancing calendar is a better planning input than the yield level, because it sets how fast a given rate move reaches interest costs. The counter-case sits in the IMF's own list of causes. High oil prices, persistent inflation, stronger investment demand and higher-than-expected AI growth have all pushed long yields up [15]. If the AI growth shows up in nominal GDP, it narrows the gap in the countries where interest rates now exceed expected nominal growth [14]. Lower oil prices that let central banks ease would also cut the interest bill.
Either outcome would make this reading too bleak. The reports do not describe either as under way, and almost every figure above is the IMF's own projection, taken from one interview and one blog post.
What to watch
- Oil prices and inflation: a decline that lets central banks cut would weaken the IMF's higher-for-longer case.
- The IMF's next projections for the share of G7 and Spanish debt maturing within a year, now approaching 30%, and for the 3.7% financing-cost path.
- Whether nominal GDP growth rises enough in countries where interest rates now exceed it to ease debt stabilization.

Rodrigo Valdes, head of the IMF's Fiscal Affairs department, said rising sovereign bond yields were adding to fiscal pressures at a time when average public debt was poised to hit 100 per cent of GDP, the highest since World War Two.

The G7's average 10-year government bond yield rose over 110 basis points between February and September, reaching its highest level in nearly two decades, the IMF said.

The average yield on 10-year government bonds across the G7 rose by more than 1 percentage point between February and September, reaching its highest level in nearly two decades, according to an IMF blog post on Wednesday.

"The fiscal results this year are worse than expected six months ago, and worse than they were one year ago," Valdes told Reuters.

The majority of countries were now looking at spending more instead of tightening their belts, Valdes said.

Governments in advanced economies were refinancing more debt at shorter maturities, so higher rates pass through to government costs more quickly; for the G7 and Spain the share of debt maturing within one year was approaching 30 per cent.

"Higher borrowing costs are adding to fiscal pressures at a time of high debt, making credible consolidation more urgent," wrote Rodrigo Valdes and deputy head Era Dabla-Norris.

"This is unfortunately like the gravity law. There's no way out of the fiscal dynamics here," Valdes said.

Valdes spoke to Reuters in an interview ahead of this week's meetings of the IMF and World Bank in Bangkok.

The IMF said the effective average cost of government financing was projected to rise to 3.7 per cent by 2031 from 2.3 per cent in 2021.

In the US, interest payments were expected to reach 5.3 per cent of GDP, up from 2.8 per cent of GDP before the COVID pandemic, roughly equal to its projected expenditure on Social Security.

In low-income countries, interest payments consume over 15 per cent of tax revenues, compared with an average of around 9 per cent between 2011 and 2019.

Inflation above target and higher energy prices meant central bankers would likely need to keep rates higher for longer, which would limit governments' ability to respond to downturns just as demands for spending on defense, energy security and aging populations were mounting.
- [14]
Interest rates on debt now exceeded expected nominal growth rates in a number of countries, which would make it even harder for them to stabilize debt.
- [15]
High oil prices, persistent inflation, stronger investment demand and higher-than-expected AI growth have driven sharp increases in long-term sovereign yields in recent months.

Financing conditions for many emerging market and developing economies had remained favorable, but might not last, the IMF said, urging those countries to reduce fiscal vulnerabilities and strengthen debt management.
- [17]
The IMF's projected effective cost of government financing rises 1.4 percentage points between 2021 and 2031.
- [18]
If debt approaching 30% of the stock repriced by the full 1.1-point rise in G7 10-year yields, one year's rollover would add up to about 0.33 points to average financing cost (an illustration assuming short-dated yields rose as much as 10-year yields).
- [19]
The illustrative one-year effect of about 0.33 points is roughly 24% of the 1.4-point decade rise in average financing cost.
