The ST Invest section articles by this author is getting bad to worst. This is just a personal opinion based on my reading. Most of the articles are about CPF and some the details are really not good advice if you look at his past articles based on my reading and perception.That article you posted, Nofear40, doesn't make a lot of sense to me. $2,190 of additional interest isn't anything to scoff at. And it's not ridiculous to assume zero withdrawals from CPF for quite some time. This maneuver (shielding) is performed at age 55. Work even another 5 years before withdrawing (i.e. retire at age 60) and that's over $11,000 of additional interest. (The interest compounds annually on the $2,190.) And that's assuming you start drawing down CPF from age 60, not other assets first.
Moreover, that's not the end of it. Shielding also lets you shift more OA dollars into RA, up to the Enhanced Retirement Sum. That's a very good deal, too.
AND the Full Retirement Sum and Enhanced Retirement Sum are increasing every year, and faster than inflation. Today's $2,190 is based on today's shielding amounts. This number is increasing faster than inflation, right along with the FRS/ERS. Next year it'll be bigger in real terms, so the real value of shielding is increasing.
AND the article talks about fees. There are no fees with SA shielding, not when you do it in any sensible way (use a zero fee platform). The author might be confusing SA shielding with the CPF Investment Scheme (OA). The only costs are the one or at most two months loss of CPF interest on the shielded amount and the slight risk of a small capital loss while the funds are inside the low volatility unit trust. (Although there's also a possibility of minor capital appreciation.)
Maybe I am not the target audience for his articles and it appeals to other people.
