For you guys opening the De Giro accounts, just make sure you get the CUSTODY account, and not the regular account. With the regular account your shares are lent to others (to be shorted I assume). Trouble is, the risks are on you should the party lending the shares not be able to return them.
This isn't an issue with the newer custody accounts.
I'm still looking at costs. At the moment if I buy VWRD through interactive, I pay 0.08% with a minimum of $1.70 per transaction. With De Giro I'd pay €2 + 0.02%.
Here's how I see the costs:
$1000 IB: $1.70 DG: €2+$0.2
$2000 IB: $1.70 DG: €2+$0.4
$3000 IB: $2.40 DG: €2+$0.6
$4000 IB: $3.20 DG: €2+$0.8 (+-$3)
$5000 IB: $4.00 DG: €2+$1.00
$10000 IB: $8.00 DG: €2+$2.00
It looks to me like there's a crossover point at around the $4000 mark, before that interactive is cheeper, and after that De Giro is cheaper. This is all provided you have $100 000 in interactive, otherwise you pay $10 per month for the account. There will be another crossover too, with IB there's a maximum fee of $39, so for very big transactions IB will be cheaper again.
In theory you could also just buy VWRD in Euros for no fees, however since I have $'s in my account and not Euros, I'd have to pay 0.1% currency conversion, so again it would only be cheaper for very small amounts.
Another theory says I should just buy VT in USD, which has TER than VWRD (0.17% vs 0.25%), but then the hoops to jump through to get the divvie tax reduced from 30% to 15%, and there's the risk of holding over $60k and dying and having to put the US estate tax treaty with SA to the test. So much to consider for a saving of a couple of $ a month!
