"Is it easier for a pan European company to keep big US competition like Robin Hood and Ameritrade out?
Niehage: 'The companies you name are very badly positioned for Europe. Their economic model is based on two pillars. Firstly, they want to offer everything for free. But if you offer all services for free, you have to earn money with the capital in the investors' accounts. That is possible in the US, where you can still get 2% of interest. In Europe, with zero interest rates, that's very different.'
And the second pillar of their economic model?
Niehage: 'That's the high frequency traders. As far as I know, Robin Hood sells its customer orders to this kind of parties. They are prepared to pay good money for that. According to the European MiFID II-regulation, that is illegal. Those two examples show that the US and EU markets are totally different. That's why American brokers have difficulties breaking into the EU market.' "
