European fiscal rules set limits to ensure that countries maintain sustainable public finances. However, excessively strict rules can be counterproductive. For this reason, they also allow for a certain degree of flexibility in exceptional circumstances, provided that sustainability is not compromised. As a result, temporary deviations from the established limits are permitted in situations that do not depend solely on the economic policy being pursued and are therefore beyond the control of the country in question.
National escape clause for defense spending
This is precisely what happens with the so-called national escape clause for defense spending. Spain has requested its activation in order to increase defense expenditure without that increase being counted, for a limited period of time, as a breach of the commitments undertaken with the European authorities.
But what exactly does it mean? What room for maneuver does it provide? And what are the consequences for public finances? The key is to properly understand what this clause allows and what it does not allow. It does not suspend fiscal rules or open the door to unlimited spending. It provides temporary, limited flexibility tied to a specific type of expenditure: defense.
What is an escape clause?
An escape clause is a mechanism designed to respond to exceptional situations. It allows a country to temporarily deviate from the commitments it has undertaken without that deviation being automatically considered a breach of what was agreed. The European fiscal framework includes different mechanisms of this kind.
Pensada para situaciones que afectan al conjunto de la Unión Europea, como una recesión económica grave y generalizada.
Which each Member State can request when exceptional circumstances beyond its control arise and have an impact on its public finances.
In this post, we focus on a specific type: the national escape clause. The exceptional circumstance in this case is linked to the war in Ukraine and the need to strengthen national and European defense capabilities, so the additional spending it seeks to accommodate must be related to defense.
How is it activated?
Activation is not automatic. The Member State must request it, the European Commission assesses the request, and the Council of the European Union authorizes the deviation and sets its duration.
With its request in April, Spain thus joins other Member States that have also asked to activate this flexibility margin.
How does it work?
The clause does not allow unlimited spending nor does it suspend fiscal rules. As it has been designed in this case, it has three main characteristics:
It is temporary: it applies to the 2025–2028 period.
It is limited: the flexibility can reach a maximum of 1.5% of GDP per year.
It is linked to defense: it cannot be used to justify any increase in public spending.
Therefore, it does not change the underlying objective of fiscal rules: to maintain sustainable public finances.
What effect does it have on the expenditure rule?
With the 2024 European fiscal reform, countries submit their respective Medium-Term Fiscal Structural Plans (MTFSPs) and commit to following an expenditure path compatible with debt reduction and the sustainability of public finances.
To reinforce that medium-term approach, the new framework also allows certain deviations, but within limits. These deviations are recorded in a control account, which acts as a record of how far a country deviates from the approved path. Under normal conditions, this account allows:
Annual control account
Deviations recorded in a specific year, provided they do not exceed 0.3 percentage points of GDP.
Cumulative control account
Cumulative deviations over the period. In this case, deviations must not exceed 0.6 percentage points of GDP.
If either of these two limits is exceeded, under normal conditions the country is considered not to have complied with the agreed expenditure path, as it has deviated too far from it.
With the escape clause activated, the assessment no longer focuses on whether the annual deviation margin is exceeded and instead concentrates solely on the cumulative balance over the period. In other words, there may be more variation in spending from one year to the next without consequences for compliance, as long as the cumulative balance remains within the permitted limits.
Does it affect the opening of an excessive deficit procedure?
Yes, it can have an effect. This procedure is the mechanism used by the European Union to ensure that Member States with excessive deficits or debt correct them. It is triggered when the agreed limits for deficit (3%) or debt (60%) are exceeded and the necessary corrective measures are not being taken.
To assess whether or not to open an excessive deficit procedure due to debt, fiscal rules look at whether the agreed expenditure path is being complied with. As we have seen, with the defense spending escape clause activated, the assessment of compliance with the expenditure rule depends only on the cumulative deviation and not on the annual one. Since there are fewer variables on which to base this assessment, the risk of breaching the debt criterion and therefore of opening an excessive deficit procedure would be reduced.
A temporary margin, not a permanent one.
The flexibility provided by the clause does not mean that the impact disappears. Higher defense spending translates into a higher deficit and higher debt compared with the initial situation, which will need to be reversed in the future in order not to jeopardize the sustainability of public finances.
When designing the next MTFSP (from 2029 onwards), countries that have used the clause will start from a less favorable fiscal position than initially expected. This will require a greater adjustment effort to maintain the sustainability of public finances, compared with the effort that would have been necessary without the clause.
According to our estimates, for every increase of 0.5 percentage points of GDP in defense spending, the additional annual adjustment required in the next fiscal plan could be around 0.13 percentage points of GDP, in terms of the structural balance.
So what does this imply for Spain?
For Spain, activating the clause has three main effects:
It allows Spain to temporarily accommodate higher defense spending within the European fiscal framework.
It changes the way compliance with the expenditure path is assessed, giving more weight to cumulative deviation than to annual deviation.
It shifts part of the adjustment effort into the future, because higher spending today may require later corrective measures, as it implies a deterioration in the path of the deficit and debt compared with the baseline scenario.
For this reason, the clause should not be understood as a suspension of fiscal rules, but rather as a limited, temporary, and conditional form of flexibility.
