Household wealth in countries with commission bans grows significantly more than in countries without commission bans, a research team from the University of Regensburg claims. They measured the difference in returns at 1.7 percent p.a. The researchers call lawmakers in countries like Germany, where the loss amounts to 2,400 euros per household per year, to ban commission-based sales of financial products.

In the recent past, Denmark, Finland, the UK, the Netherlands, Norway as well as Australia and New Zealand have introduced such bans and established alternative payment methods, e.g., according to advisory time or assets under management.
