Definition
When a dealer internalizes an order, it acts as principal and takes the other side of the client's trade, buying from or selling to the client from its own book. Under UMIR 8.1, a dealer can internalize a client order only if the client receives a price that is at least as good as the best displayed price on a protected marketplace (the NBBO) and, for dark internalization, the required minimum price improvement. Internalization benefits the dealer by earning the spread and avoiding exchange fees. Potential client harm: if the dealer skims the spread without fully passing the best price to the client, or if the dealer uses knowledge of client order flow to position its inventory favorably ahead of execution. This is why UMIR 8.1 sets strict price conditions on internalization and why CIRO surveillance monitors internalization rates and fill quality. A dealer with a high internalization rate will attract regulatory scrutiny to ensure clients are not receiving inferior fills relative to what a lit-marketplace execution would have provided.
