A study on the sustainability of Portugal’s social security system proposes eliminating tiered increases in pension updates if broader structural reforms are not implemented. The recommendations stem from an analysis of the current system’s viability. Experts suggest abandoning the existing tiered system—where pension increases vary based on the amount of the pension—as a potential measure to maintain financial stability. This proposal is presented as an alternative pathway should more comprehensive reforms, aimed at long-term sustainability, fail to materialize. The study does not detail the specifics of a replacement system, focusing instead on addressing immediate concerns. The findings underscore the urgency of addressing the challenges facing the Portuguese social security system. This move seeks to ensure pension payments remain sustainable amidst evolving demographic and economic conditions.
