Infrastructure

The OTC Clearing and Settlement System (OCASS) is the clearing and settlement system for the OTC derivatives products of OTC Clearing Hong Kong Limited (OTC Clear) and OTC Account Services Information System (OASIS) is a user interface web portal which is accessible to the Clearing Members for retrieval of different types of reports and submission of request for movement of collateral.

OCASS is a highly electronic and automated clearing and settlement system which is capable of supporting various types of OTC derivatives products. The reports which cover the settlement,  trading activities, margin requirements  and  market  data are produced by OCASS for further dissemination to the Clearing Members via OASIS. OCASS comprises the core derivatives clearing and settlement functionality and the margining engine. Different functions are well integrated in OCASS to have a one-stop system solution which yields a highly efficient workflow  for maximum synergy.    Clearing Members can access OASIS via SDNet/2 for retrieval of reports and management of collateral.

C. Key Features and Functionalities

(i) Key features and functionalities of OCASS include:

1. Product Design Model

The product design model allows considerable flexibility for the introduction of new

OTC derivatives products without the need for significant development effort.

2. Account Structure

OCASS provides a flexible account structure and different types of accounts can be established for each Clearing Member. In addition to the house position account, client position accounts will also be available when OTC Clear starts to offer client clearing services.

3. Real time novation


OCASS’s real time novation function allows trades submitted from trade affirmation platform  to  be cleared instantly during business  hours (except  for any period  of portfolio novation cycle) provided that the margin and credit check are satisfied. When a trade is submitted to OCASS for clearing, OCASS will perform two checks:

1.   Limit Check: Determine whether any pre-define limit will be breach after clearing the trade.

2.   Margin Check: Determine whether excess collateral is sufficient to cover the incremental Margin required of the trade.

The trade will not be cleared if any of the above two checks cannot be satisfied.

4. Margining

During the day, OCASS’s margining system will update initial margin of each account as new trade gets cleared and variation margin of each account with reliable market data received from independent vendor. The method of calculating initial margin and variation margin is in line with international standards and industry practice.

The margin calculated for incoming trades to be cleared will be collected upfront via real-time novation process.

5. Audit Trail

OCASS maintains an audit trail of clearing transactions and users’ activities, which can be reviewed as required.

6. Reports
