Again, if the government continues to follow the logic in the CPF Advisory Panel's most recent report, no.
That's not an actual, real world problem.
Nobody is going to be living lavishly on a BRS level CPF LIFE payout even if the BRS were to increase at 5%/year for the next decade. What an awfully strange idea, that $850/month (for example; that's roughly $150/month above current BRS level CPF LIFE payouts) is
intolerably too much lifetime retirement income. That very notion is absurd. If you're awash in CPF funds then your minimum CPF LIFE participation level is the BRS, or perhaps a little lower. Which is not even in the same universe as "insane," except insanely
low. (Raise your hand if you
want to live in Singapore on $700/month. Any volunteers?)
You really do want the BRS/FRS/ERS to rise faster rather than slower, within reason (which it would be), because that allows you to profit more from the system. It gives you more runway for tax relief, more room for MA to SA spillovers, and more room for OA to SA transfers. And all of that means more interest accrued compounded more.
If the government decides to raise the BRS/FRS/ERS by 20%/year for a half decade or more -- not going to happen -- then get back to me.
