Spanish public debt will return to be below 100% of GDP for the first time since the pandemic. This is the forecast of the Independent Authority for Fiscal Responsibility (AIReF), which anticipates that Spain will close the year with its debt at 99.9% of GDP
The reduction will return this indicator to minimum levels since 2019, the year in which it closed at 97.7% of GDP after a reduction path initiated five years earlier. The trend was cut short by the Covid-19 pandemic, a shock that convulsed the world economy.
In Spain's case, debt soared above 122% of GDP, also spurred by the contraction of the denominator during this crisis.
The forecast corresponds to the latest data offered by the Debt Observatory of the fiscal supervisor, which reviews the recent evolution of public debt, the macroeconomic and financial context, the monitoring of the new European fiscal framework by the Commission, and the forecasts for the debt of all administrations in the medium and long term.
According to the report, Spanish public debt stood at 101.6% of GDP in the first quarter of 2026, which implies a cut of 1.7 percentage points compared to the same period of the previous year.
Since the maximum recorded in the first quarter of 2021, the ratio has fallen by 22.6 points, although it remains four points above the pre-pandemic level. In nominal terms, the debt reached 1.736 trillion euros in April 2026.
AIReF recalls that Spain remains integrated into the group of European Union countries with debt levels above 100% of GDP. The correction achieved since the pandemic is mainly due to the advance of nominal GDP, which has offset the effect of a still present primary deficit, although progressively moderating, and an increasing financial burden.
It will continue a downward path
AIReF projects that the public debt ratio will decrease to 99.9% of GDP in 2026, i.e., 0.8 points less than in 2025. In the medium term, debt would continue a downward path, albeit at a slower pace as the contribution of economic growth diminishes.
However, the Observatory warns that this trend would reverse from the middle of the next decade. Population aging, the increase in interest expenditure, and weaker potential growth would push debt back onto an upward trajectory.
The sensitivity analysis carried out by AIReF shows that relatively small changes in growth, interest rates, or the primary balance can significantly alter the evolution of debt. Looking ahead to 2050, these variations would place the ratio in a range of 26 GDP points, between 111% and 137% of GDP.
Likewise, the body foresees that gross financing needs will remain contained in the first part of the projection horizon, but will gradually increase as debt regains an upward trend.
Will adjustments be needed?
The Observatory also includes an examination of the monitoring of the Medium-Term Fiscal and Structural Plan and the 2026 European Semester Spring Package. In this context, AIReF emphasizes that the evolution of debt will largely depend on the degree of compliance with the commitments included in the Plan until 2028, which will condition the adjustment needs in the next fiscal cycle.
In a scenario of strict adherence to the committed objectives, the debt dynamics would be more favorable and the additional effort required would be practically non-existent, limited to two hundredths of GDP per year.
On the other hand, if the deviation margin allowed after the application of the national escape clause for defense spending were exhausted, the necessary adjustment would increase to 0.36 GDP points annually, which would represent an accumulated effort of 1.44 GDP points between 2029 and 2032. Under an inertial scenario, without new measures, the adjustment would rise to 0.59 points per year, equivalent to 2.36 GDP points over the entire period.
