Under the SEC-IRBA framework, the risk weight attributed to a position within a Simple, Transparent, and Standardised (STS) securitisation must be determined in accordance with Article 259. Notably, there is a modified risk-weight floor of 10% specifically applicable to senior securitisation positions.

This adjustment aims to enhance the regulatory landscape surrounding securitisation, ensuring that senior positions maintain a robust framework while addressing the need for transparency and stability in financial markets.
