The significant decline in pension amounts in Türkiye compared to the past is not a coincidence or merely a current inflation problem. This situation is the direct mathematical consequence of systematic legal changes made to the social security system in 1999 and especially in 2008 to balance public finances.
Three fundamental structural changes lie behind the current economic picture and the policies implemented.
Gradual Decrease in the Replacement Rate (Aylık Bağlama Oranı - ABO)
A pension is calculated by allocating a certain percentage of the earnings reported to the SGK (Social Security Institution) throughout a person's working life to the retiree. This percentage is called the Replacement Rate (ABO). Today, when calculating a retiree's pension, their working life is divided into three separate periods, and different, progressively decreasing rates are applied to each period.
| Legal Period | Relevant Regulation | Average ABO (9000 Days / 25 Years) |
| Pre-1999 | Indicator System | 70% - 75% |
| Between 1999 - 2008 | Law No. 4447 | 60% - 65% |
| Post-2008 | Law No. 5510 | 50% |
Slashing the Growth Share (Update Coefficient)
- Pre-2008: 100% of the country's economic growth rate was added to the update coefficient. This meant the retiree received a full share of the country's general welfare increase.
- Post-2008: With Law No. 5510, the growth share was reduced to 30%. Thus, a 70% cut was made to the economic growth share reflected in pensions.
The Lower Limit of Pensions and the Collapse of the "Root Pension" (Kök Maaş)
Key Takeaway: Dividing the system into three different legislative periods systematically condemns the vast majority of the population, whose working time largely falls after 2008, to increasingly lower pensions with each passing day.
The Burden on the Treasury and the General Budget
Massive Growth in the Budget Deficit and Resource Transfer
- For millions of retirees whose root pension remains below the minimum limit, the Treasury must make cash transfers of tens of billions of liras to the SGK from the general tax pool every month.
- This massive and constantly increasing payment item is one of the biggest reasons for the structural growth of the central government's budget deficit.
Disruption of Premium Justice and Incentive for Informality
- When an employee who pays premiums based on the minimum wage and an employee who reports higher earnings (and pays more premiums into the system) receive the same or very similar pensions upon retirement, the motivation to pay high premiums is destroyed.
- This situation paves the way for employers and employees to hide actual salaries (showing premium-based earnings at the minimum wage level) and further reduces the SGK's premium revenues.
Collapse of the Actuarial Balance (System Sustainability)
- The rapidly declining "worker/retiree" (active/passive) ratio in Türkiye demonstrates that the system cannot survive without this massive subsidy from the Treasury.
- The retirement system has ceased to be a self-sustaining structure and has turned into a patient constantly receiving life support from the outside (from the Treasury).
Development Constraint and Inflationary Pressure
- Resources that should be allocated to education, technology, infrastructure, and production are inevitably diverted to close this gap.
- In order to finance this deficit, the Treasury is forced to heavily rely on indirect taxes (VAT, SCT) or resort to borrowing; this, in turn, creates a vicious cycle that triggers upward inflationary pressure.
