Credit handling in an anonymous trading system

Abstract

In an anonymous trading system, credit between counterparties is effectively increased by netting buy and sell trades to reflect the true risk to which each party is exposed. Credit limits are adjusted by calculating the exposure in each currency at the relevant time and then converted into the credit limit currency equivalent. The credit limits are adjusted accordingly. The resulting credit limits may be different for bids and offers by or from a given counterparty.

Description

[0001] This is a continuation-in-part of U.S. patent application Ser. No. 09 / 603,514, filed Jun. 23, 2000, priority of which is claimed under 35 U.S. .sctn.120.[0002] This invention relates to electronic brokerage systems and in particular to systems in which counterparties trade anonymously within fixed credit limits. Such systems may trade financial instruments such as foreign exchange and forward rate agreements. The invention is particularly concerned with the handling of credit limits.BACKGROUND TO THE INVENTION[0003] A number of anonymous trading systems are known in the art. EP-A-0,399,850, EP-A-0,406,026 and EP-A-0,411,748 all assigned to Reuters Ltd disclose aspects of an automated matching system in which a host computer maintains a central database of bids and offers submitted by terminals connected to the host via a network. The host also maintains records of credit limits between each trading bank and the possible counterparties with which it is willing to trade. The ho...

AI Technical Summary

Benefits of technology

[0014] Embodiments of the invention have the advantage that the amount of credit that must be allocated specifically to an anonymous trading system by a bank may be reduced without reducing the dealing capacity. This means that more credit is available to the bank for allocation to other trading areas as so the overall trading capacity can be increased without varying credit limits.

[0015] Embodiments of the invention also have the advantage that the netting of credit more closely resembles the actual risk to which a bank is exposed. In the prior art, a sale of $A followed by a purchase of $B from the same counterparty would have reduced the credit available with that counterparty by $A-B which equals the actual amount of risk to which one party is exposed if the other should default.

Problems solved by technology

A problem with the system outlined above is that the trader sees the bids and offers irrespective of whether he has sufficient credit with the counter party submitting that bid or offer to trade.

This is extremely frustrating for a trader, particularly in a fast moving is market in which trading opportunities can easily be lost.

The problem arises as the host computer only checks available credit after a deal has been proposed and a potential match identified.

In addition, the market distributers also have limited credit information, maintaining a credit matrix which may store a simple "yes-no" credit indicator for given counterparties.

While both the above systems have been used successfully in the financial trading markets for a number of years, they both suffer from the disadvantage that they require banks to tie up large amounts of credit in one area of their trading activities.
