One other thing to understand is that when you get to enjoy such safety in your investments and visibility in your cashflows, you need to be prepared to accept a rate of return that is close to the risk-free rate. Your first bet is to invest on Singapore Government Treasury bills and/or Singapore Government Bonds. You can also try investing on saving plans or fixed deposits but the returns are low. If you want higher returns then you really need to invest on high risk investments.
