Keytrade – owned by Crédit Agricole – offers online trading in most European markets and in North America. Fees are reasonably good, but there are probably better stock brokerage choices available for most international investors.
What could make it very useful for some is its fund supermarket, covering around 500 funds. This is worth considering alongside the better-known TD Direct Investing International (formerly Internaxx) for anyone looking for an offshore fund supermarket that will allow you to invest in Europe-domiciled funds, especially since the lack of custody charges means it may be slightly cheaper than TDII.
Keytrade has divisions in Belgium, Luxembourg and Switzerland. Since the Luxembourg arm is likely to be most popular with non-residents, the details below are taken from its terms, although there is relatively little difference between the three.
