If you have been following my post, I did my first OA investment on Oct 2022 for the 12 month T-bills.

I have split my investible OA amount into 3 tranches for the T-bill application when the T-bill interest shot up due to interest rate hike. So now I have 2 left. 

For the 2nd tranche, I will be going for the 12 month T-bill again. The 12 month T-bills will be opened on 17 Jan 2023.

This time round, because the Maturity date is so close to end of Jan 2024, It is likely going to be February 2024 before the money can be transferred back to my CPF OA. So essentially I will not be getting the 2.5% CPF OA interest from Jan 2023 to Feb 2024, a total of 14 months.
