The answer is math
Switching between two ETFs carries transaction costs and even at the cheapest rate you’re likely to get of say 0.25% on the buy and sell side, that means you’re spending 0.50% on transaction costs. Add the other statuary fees and the spread (difference between buy and sell price on the JSE). Suddenly that switch is costing you more than 1% and potentially a lot higher if you have a higher brokerage rate.
So if the switch is only saving you 0.05% on the TER and it’s costing you 1% to do the switch. The math says it’ll take twenty years for your TER savings to have paid off the cost of that switch,
If the TER difference is large, say 0.5%, well then it’s just a couple of years before your savings are ahead of the cost of the switch.
So run the numbers and check if it works.
Tax
You will potentially have a tax hit on the sale and that could be a lot which would make any switch a horror bad idea. You sell to save a little and get hit with a giant tax bill.
Of course if you’re holding in a tax-free account then this is moot.
For me personally, I seldom switch just for a slightly lower fee. However I will put new money into the cheaper ETF going forward.
