A simple way to guesstimate the reserves

The non transparent secret of the country’s reserves, speculated to be worth $1 trillion has been subjected to many queries as to what is really there. As it is a closely guarded state secret, no one really knows, even the President that holds the second key to guard the reserves. In a way, the reserves could be like a mirage of a mountain of gold. The people could imagine or were told that it is large and is there, but cannot feel or touch it. The big question in many people’s mind is whether this is true. It is only fair for any reasonable man to have doubts about something that is like what the salesman told them, and they have to believe his words, to trust him.
 
When the people are kept in the dark, it is very difficult to know the truth. The more the govt tries to hide this info, the more suspicious will be the people who want to know the truth. And the more the govt is frantically trying to raise taxes, even very unpopular measures, the more worried would be the people as to the health of this gold mountain mirage. Simple, got so much money no need to panic to raise so many taxes. The reason that the reserves cannot be touched, to be kept for the rainy day, is hogwash. It was touched many times during Nathan’s days.
 
Let’s see what we can extrapolate from some of the official statistics provided by Heng Swee Kiat to figure out how much is there in the reserves. The estimated NIRC for FY2018 is $15.9. I am not sure this is profit earned for the whole year prior to FY2018 or the estimated returns for FY 2018, ie not earned yet. But putting this aside let’s just use this number as a basis to extrapolate the reserves gold mountain.
 
The $15.9b is net return, ie after paying 2.5%/4%/5% interest to CPF members, estimated at $400b borrowed. If we use a 3% interest paid to CPF, this would work out to be $12b. The gross profit from the funds invested, less expense other than CPF interest, would be $12b + $15.9b +15.9b = $43b. Assuming NIRC is 50% of net income and balance 50% went into the reserves.
 
The govt has been using a 3.5% figure as the returns from investing our reserves. Thus if $43b is the gross return or 3.5%, the reserves should be $1.23 trillion. If we use just the $31b as net return, the reserves should be $886b. Could have use $32b ie 15.9 +15.9
 
But 3.5% return is supposed to be an average. The estimated return of $31b could be 5%, 7.5% or 10% over the years. These would give the reserves as $620b, $413b and $310b respectively. I use the different percentages to show that the higher the rate of return, the lower would be the reserves.
 
Alternatively if we use $43b as the gross return and 5%, 7.5% and 10% return, the reserves could be $860b, $573b and $430b respectively.
 
The good news, the reserves could be as high as $1.23t or $886b. The bad news, it could be as low as $310b or $430b.
 
If the funds are not performing that well, ie making a 3.5% return, then the reserves could be in the region of $886b to $1.23t. Someone said the interest rate for long term interest, risk free is about 3%. What is the point of paying hundreds of millions to fund managers to bring in 3.5% with high risk of losing the capital. Sack the whole bunch if they cannot bring in more than 5% returns.
 
Extrapolating from the rate of returns based a given NIRC of $15.9b, the paradox is that higher the percentage of returns means lower reserves and vice versa. If the funds are doing well, ie making returns of 5%, 7.5% or 10%, then the reserves could be quite scary, like a glittering golden mountain but not all gold.
 
What is the real thing, when would this be made known, or forever be in the unknown?
 
PS. MOF stats stated that GIC has a 20 year annualized return of 3.7% while Temasek’s annualized return from 2002 to 2014 is 15%.
