Principal vs. Agency Trades

Dealer trading from inventory (markup) versus broker executing for a client (commission).

What is Principal vs. Agency Trades?

Acting as agent (broker), the firm finds the other side of the trade and charges a commission. Acting as principal (dealer), it buys from or sells to the client out of its own inventory and earns a markup or markdown. A firm cannot charge both on the same trade, and the capacity must be disclosed on the confirmation.

Principal vs. Agency Trades: a worked example

A firm sells a client a bond from inventory at $1,020 that it values at $1,000 - a $20 markup, as principal.
