In my last blog post, I made a passing mention about a 6 month T-bill which I bought using money in my CPF-OA maturing in the same week. I made a request to transfer the money back to my CPF-OA when I saw the funds sitting in my CPF-IA a day later. It was all rather easy with DBS online banking. I simply logged in and went to the "Invest" tab and selected "More investment services." Then, I chose "Refund to CPF Board." Clicked on "Refund Full Amount", and it was basically done after clicking "Next" and "Submit." Today, I checked my CPF account and found that the funds are back in my CPF-OA. Now, I am wondering whether I should buy another 6 months T-bill with the money. To be quite honest, I am not as enthusiastic as before because the cut-off yield has reduced so much since the start of the year for 6 months T-bills....
