In 24 years of the existence of the so-called "Swiss rule" for the annual updating of pensions, it has been applied 14 times. In the remaining 10 years, pensions have either not been increased at all, or another approach to increase has been chosen.
According to data from the National Social Security Institute, the highest rate of updating under the Swiss rule was achieved in 2023 - 12%, and the lowest was in 2015 - 1.9%.
This is calculated by the Bulgarian National Radio.
Pensions did not receive any increase in three consecutive years - between 2010 and 2012. Before that, the updating rule was suspended in 2008, with recalculation based on the current insured income.
In 2006, the percentage of increase depended on the amount of the pension, a year later there were two indexations - by 10% from July and from October. In 2009, the coefficient of each year of service in the pension formula was increased from April and the Swiss rule was applied from July.
In 2013, the percentage of updating depended on the year of granting the pension. This was followed by three consecutive years - 2017 to 2019, in which the coefficient per year of service in the formula was increased. The last time this was done was at the end of 2021, and in the same year from July the pensions were also indexed according to the Swiss rule.
In 2022, pensions also received an increase outside the rule twice - from July 1 - by 10% plus a 60 leva Covid supplement, and from October they were recalculated individually for each pensioner based on insurance income back in time.
