The main drawbacks of a pension lump sum are shifting investment risk and management responsibility to you, the potential to outlive your savings (longevity risk), high upfront taxes, and the temptation to overspend, all while potentially losing valuable survivor benefits or inflation protection that a monthly annuity offers. You become solely responsible for making the money last a lifetime, managing market volatility, and avoiding scams, which requires financial discipline and expertise.
