As world financial markets progress, expand and link into a global marketplace and as counterparty credit risk multiplies and becomes more complex, OCC’s guarantee function continues to protect clearing members and their customers. OCC has received an ‘AA+’ credit rating from Standard & Poor’s (S&P) because of its ability to fulfill obligations as the counterparty for exchange-traded derivatives.
OCC stands behind every cleared trade that has been executed on the markets and exchanges it serves, in addition to stock loan transactions executed through the Stock Loan program. OCC assures performance to selling (lending) and purchasing (borrowing) clearing members, eliminating counterparty risk. OCC in effect becomes the buyer (borrower) to every clearing member representing a seller (lender) and the seller (lender) to every clearing member representing a buyer (borrower). The substitution of OCC as counterparty is achieved through a legally binding novation process that has withstood the test of time. This process supports fungibility for the contracts OCC clears and facilitates a liquid secondary market.
