Spain's Minimum Wage Hikes Leave 45% of Collective Agreements Outdated 2026

Spain's minimum wage, known as the SMI, has climbed steadily since 2018, and the cumulative effect is now colliding with the country's collective bargaining system. The latest data shows that 45% of collective agreements registered in early 2026 set entry-level pay below the legal minimum, effectively making them obsolete.

The SMI has risen from 735 euros per month in 2018 to 1,221 euros in 2026, paid in 14 installments—a 66% increase. That pace has outpaced many sectoral negotiations, leaving agreements that were months in the making dead on arrival.

Why Collective Agreements Are Falling Behind

Collective agreements are meant to set the rules of the game for sectors or large companies, including wage floors for various job categories. But when the legal minimum rises faster than these agreements are updated, the lowest pay scales become invalid.

According to an analysis by the UGT union, the SMI now exceeds the agreed salary for the lowest categories in 45% of sectoral agreements registered in the first quarter of 2026. That means nearly one in two agreements has minimums that are below the new legal threshold.

Company-level agreements fare slightly better, but the problem persists. Of the 25 company agreements published in the same period, a smaller share—though still significant—are outdated.

The Scale of the SMI Increase

Real-World Impact: The Gardening Agreement

A concrete example illustrates the problem. The gardening agreement approved in January 2026 set a salary of 1,184 euros for peons and apprentices—aligned with the 2025 SMI but not the new 2026 figure of 1,221 euros.

This means workers covered by that agreement would legally be entitled to the higher SMI, but the agreement itself does not reflect it. Employers and unions must renegotiate or apply the legal minimum directly, which can lead to confusion and disputes.

Who Is Affected and Why It Matters

The outdated agreements affect both workers and employers. For workers, the risk is that some may not receive the full SMI if payroll systems are not updated. For employers, outdated agreements create legal uncertainty and potential back-pay liabilities.

The situation also undermines the collective bargaining process. When agreements are negotiated over months only to be rendered obsolete by a subsequent SMI hike, trust in the system erodes.

• 45% of sectoral agreements registered in Q1 2026 have minimum pay below the SMI.
• The SMI has risen 66% since 2018, from 735 to 1,221 euros per month.
• Company agreements are less affected but still show outdated scales.
• Example: gardening agreement set 1,184 euros for peons, below the 2026 SMI.
• Workers and employers face legal uncertainty and potential wage adjustments.

What to Watch Next

Unions are calling for faster renegotiation of affected agreements. The government has not announced a mechanism to automatically update collective agreements when the SMI rises, leaving it to social partners to resolve.
