BRUSSELS — Belgium’s federal government is pushing forward with its controversial wage indexation cap, known as the centenindex, despite fierce opposition from labor unions and political parties like CD&V. The measure, set to take effect in June 2026, will cap wage increases for employees earning more than €4,000 gross per month at a flat €80 increase—regardless of inflation—while leaving lower earners unaffected. With the legislative proposal already submitted to parliament and no alternative in sight, the policy is now entering its final stages of approval, setting off a political and labor backlash.

Critics, including CD&V leader Wouter De Wever, have labeled the centenindex the “largest camel ever designed”, accusing the government of betraying workers and small businesses. Meanwhile, labor unions and employer groups continue to lobby for alternatives, but with no consensus in sight, the measure appears poised to become law. Here’s what you need to know about the centenindex, its economic impact, and the political battle still raging over its implementation.

What Is the Centenindex, and How Will It Work?

The centenindex is a two-step wage indexation mechanism designed to limit the impact of inflation on higher earners. Under normal circumstances, Belgian wages are automatically adjusted for inflation, typically around 2% annually. However, the centenindex introduces a ceiling: for employees earning more than €4,000 gross per month, only the portion of their salary up to €4,000 will receive the full indexation. The excess above €4,000 will receive a flat €80 increase—equivalent to 2% of €4,000—rather than a percentage-based adjustment.

For example, if inflation triggers a 2% indexation and an employee earns €5,000 gross per month, they would receive a €80 increase (2% of €4,000) rather than €100 (2% of €5,000). This policy is scheduled to be applied twice during this legislative period: once in June 2026 and again in January 2028.

Similarly, pensions and unemployment benefits above €2,000 gross per month will also be capped, receiving a flat €40 increase instead of full indexation.

Why Was the Centenindex Created?

The measure was introduced as part of Belgium’s broader budget agreement, aimed at reducing public spending and controlling wage growth in the public sector. The government argues that the centenindex will help moderate labor costs without disproportionately affecting lower-income workers. However, critics contend that the policy unfairly targets middle-class and higher earners while doing little to address the root causes of inflation.

According to the Belgian Federation of Employers (SD Worx), the centenindex is part of a broader strategy to align wage growth with economic reality, particularly in sectors where salaries have outpaced productivity gains. The policy also includes a patronage contribution, requiring employers to pay half of the savings generated from the capped indexation to the government.

Who Is Affected by the Centenindex?

The centenindex will impact approximately 20% of Belgian workers, primarily those earning between €4,000 and €6,000 gross per month. According to recent estimates from the Belgian National Institute for Statistics (Statbel), around 600,000 employees could see their wage increases reduced under the new policy. public sector workers, including civil servants and teachers, will also face the cap, though some exemptions may apply for essential services.

Pensioners and recipients of unemployment benefits above €2,000 gross per month will similarly see their increases limited to €40 per indexation period.

Who Supports the Centenindex?

The current federal government, led by Prime Minister Alexander De Croo, has defended the measure as necessary to stabilize public finances and prevent a wage-price spiral. The policy enjoys support from center-right and liberal parties, including the Open VLD and MR, which argue that unchecked wage growth exacerbates inflation.

Employer groups, such as SD Worx and FEB (Federation of Enterprises in Belgium), have also expressed cautious support, citing the need for predictable wage costs in an uncertain economic climate.

Who Opposes It?

The centenindex faces united opposition from labor unions and the CD&V party, led by Wouter De Wever. CD&V has threatened to block the budget if the centenindex is not revised, while labor unions, including the CNT and CSC, have organized protests and called for a unified front against the measure.

In a recent statement, CD&V’s economic spokesman described the centenindex as “a betrayal of the social contract”, arguing that it disproportionately affects middle-class families while failing to address the true drivers of inflation, such as energy costs and global supply chain disruptions.

“This is not about fairness. This is about punishing the wrong people at the wrong time.”

Labor unions have proposed an alternative: a progressive indexation system that would increase benefits for lower earners while capping wage growth for top executives. However, the government has so far rejected these proposals, stating that any changes would require renegotiating the entire budget agreement.

What Happens Next?

The centenindex legislation is currently under review in the Belgian Chamber of Representatives. If approved, it will take effect in June 2026, with a second application planned for January 2028. However, the political stalemate remains unresolved:

• CD&V and labor unions continue to push for amendments or a complete repeal, threatening to block the budget if their demands are ignored.
• The government has rejected negotiations, insisting that the centenindex is a non-negotiable part of the budget deal.
• Protests are expected to escalate in the coming weeks, with unions planning nationwide demonstrations in Brussels and other major cities.
• Employer groups remain divided, with some supporting the measure and others calling for further modifications.

The next critical deadline is May 20, 2026, when the Chamber of Representatives is scheduled to vote on the final version of the budget bill. If the centenindex is included, it will likely become law unless CD&V and its allies can muster enough votes to amend or block it entirely.

Key Takeaways: What the Centenindex Means for Workers and Employers

• Lower earners (under €4,000 gross/month) will see no change in their wage indexation.
• Higher earners (over €4,000 gross/month) will receive a flat €80 increase instead of a percentage-based adjustment.
• Pensioners and unemployment beneficiaries earning over €2,000 gross/month will see their increases capped at €40.
• Employers will face lower wage costs but must contribute half of their savings to the government.
• Public sector workers will also be affected, though some essential services may receive exemptions.
• The policy is set to be applied twice during this legislative period (2026 and 2028).

A Final Word: Will the Centenindex Survive?

As Belgium’s political landscape remains volatile, the centenindex’s fate hangs in the balance. While the government appears determined to push the measure through, the opposition’s resistance is far from over. With protests planned and CD&V threatening legislative action, the coming weeks will be critical in determining whether the centenindex becomes a permanent fixture of Belgian wage policy—or a casualty of political compromise.

One thing is certain: this debate is far from settled. As labor unions and employer groups continue to negotiate, workers across Belgium are left wondering how much longer they can afford to wait for a fair solution.
