Thailand's Civil Service Pension Fund (GSIS) is drafting legislation to allow former members to reinvest lump-sum retirement payments and redirect monthly pensions back to the fund for management. With 1.29M members and 1.58 quadrillion baht in assets, the fund is also studying a shift from traditional Strategic Asset Allocation (SAA) to Total Portfolio Approach (TPA) to better manage risk across diverse assets. A survey of 100K members found 80–90% interested in continuing contributions; draft law expected by year-end. This matters for SMEs because pension reform affects employee savings behavior, fund investment strategy, and fiscal policy.
