Now that UOB and OCBC have come up with something, feels like it's only a matter of time for DBS/POSB to. Don't think these robo businesses can make any money (especially with the infrastructure costs) if they charge only sales charge. However, if they can charge 0.25% per annum or under, they're going to be able to undercut a lot of guys here.
OCBC wanna charge 1.5%....
