Now interest rates moving up, even for SSBs and 10yr SGS, will we be looking to more than 2.5% for our hard earned lock up funds which have no exit until old age (30-40 yr fixed deposit)?
CPF OA interest rates are pegged to bank interest rates in Singapore. Here's CPF's most recent rate announcement for 2Q2018:
CPF said:
The interest rate on Ordinary Account (OA) monies is reviewed quarterly. OA monies earn either the legislated minimum interest of 2.5% per annum, or the 3-month average of major local banks' interest rates, whichever is higher.
The OA interest rate will be maintained at 2.5% per annum from 1 April 2018 to 30 June 2018, as the computed rate of 0.24% is lower than the legislated minimum interest rate.
Unless bank interest rates in Singapore move substantially higher, or the government decides to change the formula (very unlikely but not totally impossible), OA interest rates will stay at 2.5%.
If you're unsatisfied with 2.5% and think you can do better, no problem. Before your 55th birthday you have three major alternatives (and some less common ones, but I'm listing the major ones):
(a) You can use OA funds for housing, if you'd like to try to be a real estate tycoon. (I wouldn't, but up to you.)
(b) You can transfer OA funds into SA, up to the current Full Retirement Sum. The SA interest rate is 4.0% plus possible bonus interest if you haven't maxed that out. This move can be very smart.
(c) Via the CPF Investment Scheme (OA), you can invest in a variety of onshore securities. You can make a reasonable argument in favor of the CPF Investment Scheme into, for example, the lowest cost STI ETF you can find, if you have a long enough time horizon and if you've maxed out option (b) already.
On your 55th birthday, option (b) disappears but a new option (d) appears:
(d) You can withdraw some or all of your CPF savings, after you have set aside your retirement savings (which goes toward CPF LIFE). However, your withdrawal will come first from your Special Account then, once that's empty, from your Ordinary Account.
You might be able to shield your SA funds via the CPF Investment Scheme (SA), using something that's temporary, low risk, and low cost, and then make your one-time withdrawal while your SA funds are briefly shielded. But that "hack" doesn't work for frequent withdrawals since you'd lose too much SA interest.
