Federal Court Ruling Strengthens Rights for Millions with Riester Pensions

Wed 10th Dec, 2025

The Federal Court of Justice (BGH) in Karlsruhe has issued a significant ruling favoring holders of Riester pension contracts. The decision, which affects millions of policyholders across Germany, addresses a central clause in certain unit-linked Riester pension insurance agreements. According to the judgment, insurers are no longer permitted to unilaterally reduce the pension conversion factor during periods of poor market performance unless the contract also provides for proportional increases when market conditions improve.

The Riester pension, introduced in 2002, is a state-supported private retirement plan designed to supplement statutory pensions. Many contracts, particularly those concluded between June and November 2006 with major insurance providers, included provisions that allowed insurers to decrease the monthly pension payout if the investment returns fell to a level that endangered the security of long-term payments. The conversion factor determines how accumulated capital is translated into monthly pension payments and is thus a crucial element in retirement planning.

In the case reviewed by the BGH, the insurance provider had invoked this clause during a prolonged phase of low interest rates, leading to the reduction of the pension conversion factor for affected policyholders. While the insurer maintained that such adjustments were necessary to ensure the sustainability of payments, consumer protection organizations argued that these clauses unfairly disadvantaged customers by allowing one-sided changes without the prospect of future improvements.

The BGH found that a contractual term permitting only downward adjustment of the conversion factor is inadmissible. The court emphasized that policyholders must be treated equitably: if a contract allows for reductions in unfavorable conditions, it must also guarantee equivalent upward adjustments should circumstances become more favorable. The absence of such a reciprocal mechanism in the contractual terms was determined to be unreasonable for customers, leading the court to declare the clause invalid.

The ruling underscores the BGH's view that insurance contracts must strike a fair balance between the interests of providers and customers. While insurers retain limited rights to alter conversion factors in response to substantial and sustained changes in capital market conditions, any adjustments must be governed by transparent and balanced contractual provisions. Unilateral reductions without corresponding opportunities for increases are no longer permissible.

Major insurers have responded by stating that their contracts issued since 2007 already comply with the new requirements, including clauses that allow for adjustment in both directions. They have further clarified that changes to the conversion factor do not affect the guaranteed benefits or the total contractual value for policyholders.

The decision is expected to have wide-reaching implications for the insurance industry and millions of Riester pension savers. Consumer advocates note that similar clauses have been widespread in older contracts, suggesting that many customers could benefit from the judgment. Insurers will now need to review their contractual terms to ensure compliance with the BGH's standards, and affected policyholders may be entitled to have previous reductions to their pension conversion factor revisited.

This landmark ruling reinforces consumer protections and sets a legal precedent for the treatment of adjustment clauses within private pension contracts in Germany. Industry experts advise those with Riester pensions to review their agreements and seek advice regarding their rights under the updated legal framework.
