Spain's Toledo Pact as a grand bargain: what Matthew Miller's idea teaches Spanish pensions

Matthew Miller's The Two Percent Solution (2003) proposes solving big, blocked problems through grand bargains: the left accepts tools it distrusts, the right pays for the problem at its real size, and both sides get something they value. Spain has been running something close to that on pensions for three decades, under the name of the Toledo Pact. Reading it through Miller's lens explains why it has lasted, and what the next round needs.

Thirty years of a pension pact

The pact was born in Congress on 6 April 1995, at a time of growing doubts about how pensions would be financed. The Seguridad Social's own history of the pact lists fifteen recommendations in that first document. Among them: a reserve fund to soften economic cycles, contribution bases closer to real wages, separate financing for contributory and non-contributory benefits, protection of purchasing power, and better widows' and orphans' pensions. A 1997 law turned them into rules, including a fifteen-year period for calculating the pension.

From 1999 a permanent parliamentary commission took charge of reviewing the pact. It issued reports in 2003, with 22 recommendations, and in 2010, with 21. The 2011 reform that followed raised the retirement age gradually to 67 and extended the calculation period to 25 years.

Then the bargain broke. A 2013 reform introduced a sustainability factor and a new revaluation index outside the consensus. It took nearly ten years and several legislatures to agree a fourth report. When it came, in October 2020, its recommendations aimed to restore financial balance by moving costs that do not belong to the contributory system onto the state budget, and to guarantee purchasing power through indexation to inflation. The Seguridad Social describes it as a return to the consensus that existed before 2013.

The deal in the 2021–2023 reforms

The laws that followed show the bargain's shape clearly. Ley 21/2021, which the preamble of the 2023 reform describes as built on the consensus reached in the Toledo Pact and with unions and employers, restored annual revaluation to protect purchasing power and added incentives to keep working.

Real Decreto-ley 2/2023 completed the package. On the revenue side, it created the intergenerational equity mechanism, an extra 1.2-point contribution (1% paid by employers and 0.2% by workers once fully phased in) that feeds the reserve fund until 2050. It added a solidarity contribution on pay above the maximum contribution base, at 5.5%, 6% and 7% in rising bands, phased in from 2025 to 2045. The maximum base rises each year with pensions plus an extra 1.2 points from 2024 to 2050, while the maximum pension rises by an extra 0.115 points a year, partly compensating higher earners. On the benefit side, minimum retirement pensions for a pensioner with a dependent spouse must not fall below the poverty line for a two-adult household by 2027, and a new calculation, phased in from 2026, lets people count their best 27 years of contributions out of the last 29.

The 2023 decree also replaced the 2013 sustainability factor, which would have cut initial pensions automatically. In its place it put a different kind of automatic mechanism: AIReF, the independent fiscal authority, reports on whether revenue and spending stay on track, and any deviation triggers a corrective procedure with the social partners. The government must also report regularly to the Toledo Pact's permanent commission.

So each camp got its core demand. The left got indexed pensions, higher minimums and a levy on top salaries. The right got earmarked revenue, a reserve fund rebuilt for the baby-boom years and rewards for later retirement. Both agreed to a referee.

Is it working?

Some results are visible. In September 2026 the Seguridad Social paid 10,547,417 contributory pensions to more than 9.5 million people, with a monthly bill of €14,498.2 million. The average pension was €1,374.6, and the average retirement pension €1,576.1. Up to August 2026, 11.6% of new retirements were voluntary delays, 6.8 points more than in 2019, and the average age of retirement had risen to 65.4 from 64.4 in 2019. Incentives to work longer are doing what the right hoped they would.

The fiscal picture is more mixed. AIReF's May 2026 report finds the pension spending rule formally met: spending net of the new revenue measures averages 13% of GDP between 2022 and 2050, three tenths below the 13.3% threshold. Gross pension spending averages 14.6% of GDP, with revenue measures worth 1.6%. AIReF still warns that meeting the rule does not remove the strain on public finances. Under constant policy, public debt climbs to 123% of GDP by 2050. It also argues the rule rests on a partial view of sustainability, limited to pension spending, and suggests revising it.

What the next round needs

Miller's lesson is that a grand bargain fails when one side pays and the other only collects. On Spanish pensions the money side is now strong. The weak point is the frame. The current rule looks at pensions in isolation, while the real constraint is the whole budget and the debt that the young will inherit.

The next Toledo report should widen the deal. The left keeps what it won: indexation, the minimum pension at the poverty line and the solidarity contribution. The right gets a sustainability rule tied to total public spending and debt, as AIReF suggests, with automatic correction that falls first on the revenue and timing levers before touching the pensions people are already drawing. More flexible retirement, building on the incentives that are already working, should sit inside the package.

And the referee should get stronger. The part of the Toledo Pact that fits neither left nor right is its institutional habit: a standing commission and an independent fiscal authority that keep checking the numbers in public. That habit is why Spain's pension bargain has survived thirty years and one rupture. Making AIReF's annual verdict the trigger for every future adjustment would make the pact credible to the generation that will pay for it.
