In line with the methodology of Article 5 of the Delegated Regulation, ING's score is 148 base points (based on data as at 31 December 2022), placing the institution again in subcategory 1, for which the G-SII buffer has been set at 1% of the total risk exposure amount.
On balance, this buffer will not affect ING’s risk-weighted capital requirement, given that its Other Systemically Important Institution (O-SII) buffer has been set higher and only the highest of the two counts. The O-SII buffer of ING is currently 2.5% and becomes 2% as of 31 May 2024, see here.
Every year, the Basel Committee on Banking Supervision (BCBS) and the Financial Stability Board (FSB) also publish the methodology for identifying G-SII's (or G-SIBs) and the annual outcomes.
