The effects of recent Spanish pension reforms on sustainability and pension adequacy

The Spanish pension system has been recently reformed as a response to the demographic challenge and with the objective of ensuring the sustainability of the pension system in the long-term. The overall reforms include changes in the majority of the system parameters, a new indexation rule and a sustainability factor that links life expectancy and the first pension amount. The aim of this work is to analyse how these reforms affect two important features of a pension system: fiscal sustainability and adequacy. For this purpose, the real internal rate of return (IRR) of the lifetime contributions and benefits and the prospective gross theoretical replacement rate (TRR), both before and after the reforms, have been computed. The calculations are case-study based, for a few hypothetical workers who are sufficiently representative of the earnings and retirement patterns in Spain. The results show that the real IRR is 0.7 p.p. lower and the prospective gross TRR is 18 p.p. lower after the reform process for the base case of a man with an uninterrupted career of 40 years with average earnings and a retirement age of 65. In addition, pension reform process in Spain has different effects among the individuals depending on the gender, level of earnings, retirement age and career length.
