Yes, I finally opened up a CPF Investment Account (CPFIA) for my OA with DBS and the first Investment I did with my CPF OA is the Oct 1 year T bill as mentioned in my previous post. I didn’t go for ETFs like S&P 500 using Endows because I may need the money in my OA for my housing loan in around 3 years' time when my fixed interest rate mortgage term is up. If the bank's mortgage rate is higher than the CPF OA interest at that point, I will have the choice to repay the loan using my CPF OA and lowering the monthly payment. Considering the short term need for my OA money, I went for a low risk instrument like Government T-bills to boost my OA interest. I am hoping that this Oct issue will have a yield of 3.2% or more to make all these effort worthwhile....
