Main content of this article is the second picture in this article. Yes, you can just read that picture and ignore the text. SA–CCR: Standardised Approach for Counterparty Credit Risk Exposures.

Background

As a part of Basel III, SA–CCR will be fully effective in June 2021, and it has been implemented or is being implemented in some medium-sized and large banks, which are among target clients of SAP Bank Solutions.

SA–CCR calculation is relative complicated: from SDL till report it takes about ten layers.  This article tries to provide an overview of the SA–CCR structure in a single picture.
