Fixed Income Derivatives

• Credit Token
• Linking of Repo Legs

Credit Token

Recent years have seen a regulatory drive to move over-the-counter (OTC) trading in liquid derivatives onto organized venues. The aim is to bring transparency into the OTC sphere for the mutual benefit of both investors and regulators. In addition to this investors may benefit from deeper liquidity etc. by moving onto electronic marketplaces. MiFID II and MiFIR generally apply to transactions in financial instruments in asset classes concluded on venue or over-the-counter. More specifically MiFID II (RTS 26) requires trading venues to perform pre-trade checks against the limits set and maintained by clearing members for its clients and to send electronically executed trades to the CCP within 10 seconds. The CCP then in turn must accept or reject such trades within 10 seconds. In order to keep within these narrow time limits, and to adhere to certainty of clearing, an automated limit check must ideally be in place in order to avoid delays. The pre-trade credit check is conducted by the trading venue. If this check is successful it is evidenced by the presence of a “credit token”. The credit token is then attached to the trade message sent by the trading venue via MarkitWire to Nasdaq Clearing. The presence of a credit token in a client-dealer trade will void the necessity of the client’s clearing broker to affirm the trade and pre-novation will be initiated immediately. If a credit token is not present in a client-dealer trade the usual trade flow will apply, i.e. the client’s clearing broker have to affirm the trade before it can be novated. The products in scope are swaps and FRA’s.
