Deutsche Bank, one of the largest brokers in European equities, has split its fund management clients into three tiers according to how much commission they pay the firm and how profitable each account is.

The German bank has divided its clients into what it calls platinum, gold and silver accounts after an exhaustive analysis of its client base. Platinum accounts are understood to pay Deutsche more than €10m ($12m) in commissions, gold accounts pay between €2.5m and €10m, while silver accounts receive an execution-only service. The bank declined to comment on the breakdown of the individual categories of the service it provides.
