It is not easy (In fact very very difficult) for CPF OA rate to be above 2.5% based on the way CPF calculate the interest.
We can just calculate just to break even at 2.5%:
Let's fix the saving interest rate at 0.05%
FD*0.8 + Sav*0.2 = 2.5%
FD*0.8 + 0.05*0.2 = 2.5%
FD = 3.1125%
12 months Fixed deposit rate for the 3 local banks need to be average 3.1125%

DBS always offers the highest rate, follow by UOB and OCBC is the lowest.
Using DBS as example, you can see there are different rates for different amount range for the first $50k and this will further average down the 12 months FD rate. It will be much lesser than 1.15%.
We are already in the high interest rate environment and the 12 months FD rate is less than 1.15%.
Note: We cannot use bank promotional 12 months FD rate for the calculation.
What is the probability for the local 3 banks 12 months FD to hit more than 3.1125%. Personally, I think it will be extremely unlikely or near impossible.
Thanks to the CPF formula for calculating CPF OA interest rate, it is extremely difficult to be above 2.5%.
(Anyway it is design in such way, too many things are tied to CPF OA interest, such as HDB loan and CPF don't want to give out more money, more expense)
