A method and system for executing foreign exchange transactions anonymously via an online communications network with minimal market impact at a transparent price. An embodiment of the present invention involves a novel execution product offering two distinct services. The first is a crossing service in which buy and sell orders for each currency pair are matched directly against each other for execution at a future benchmark rate. The matching of orders and the clearing and settlement of each execution is facilitated and no market risk is undertaken. The second service is an optional residual program where, if a 100% fill on an order is desired, the customer can choose to have unmatched or residual of orders executed at the benchmark rate. Market risk associated with guaranteeing the Benchmark rate is undertaken, just as it is with the current benchmark execution process. For both services, customers pay a transparent commission.
