1. Member States shall designate the authority in charge of identifying, on a consolidated basis, global systemically important institutions (G-SIIs), and, on an individual, sub- consolidated or consolidated basis, as applicable, other systemically important institutions (O-SIIs), which have been authorised within their jurisdiction. That authority shall be the competent authority or the designated authority. Member States may designate more than one authority. G-SIIs shall be an EU parent institution, an EU parent financial holding company, an EU parent mixed financial holding company or an institution. G-SIIs shall not be an institution that is a subsidiary of an EU parent institution, of an EU parent financial holding company or of an EU parent mixed financial holding company. O-SIIs can either be an EU parent institution, an EU parent financial holding company, an EU parent mixed financial holding company or an institution.
2. The identification methodology for G-SIIs shall be based on the following categories:
(a) size of the group;
(b) interconnectedness of the group with the financial system;
(c) substitutability of the services or of the financial infrastructure provided by the group;
(d) complexity of the group;
(e) cross-border activity of the group, including cross border activity between Member States and between a Member State and a third country.
Each category shall receive an equal weighting and shall consist of quantifiable indicators.
The methodology shall produce an overall score for each entity as referred to in paragraph 1 assessed, which allows G-SIIs to be identified and allocated into a sub-category as described in paragraph 9.
3. O-SIIs shall be identified in accordance with paragraph 1. Systemic importance shall be assessed on the basis of at least any of the following criteria:
(a) size;
(b) importance for the economy of the Union or of the relevant Member State;
(c) significance of cross-border activities;
(d) interconnectedness of the institution or group with the financial system.
4. Each G-SII shall, on a consolidated basis, maintain a G-SII buffer which shall correspond to the sub-category to which the G-SII is allocated. That buffer shall consist of and shall be supplementary to Common Equity Tier 1 capital.
6. When requiring an O-SII buffer to be maintained the competent authority or the designated authority shall comply with the following:
(a) the O-SII buffer must not entail disproportionate adverse effects on the whole or parts of the financial system of other Member States or of the Union as a whole forming or creating an obstacle to the functioning of the internal market;
(b) the O-SII buffer must be reviewed by the competent authority or the designated authority at least annually.
7. Before setting or resetting an O-SII buffer, the competent authority or the designated authority shall notify the Commission, the ESRB, EBA, and the competent and designated authorities of the Member States concerned one month before the publication of the decision referred to in paragraph 5. That notification shall describe in detail:
(a) the justification for why the O-SII buffer is considered likely to be effective and proportionate to mitigate the risk;
(b) an assessment of the likely positive or negative impact of the O-SII buffer on the internal market, based on information which is available to the Member State;
(c) the O-SII buffer rate that the Member State wishes to set.
9. There shall be at least five subcategories of G-SIIs. The lowest boundary and the boundaries between each subcategory shall be determined by the scores under the identification methodology. The cut-off scores between adjacent sub- categories shall be defined clearly and shall adhere to the principle that there is a constant linear increase of systemic significance, between each sub-category resulting in a linear increase in the requirement of additional Common Equity Tier 1 capital, with the exception of the highest sub-category. For the purposes of this paragraph, systemic significance is the expected impact exerted by the G-SII's distress on the global financial market. The lowest sub-category shall be assigned a G-SII buffer of 1 % of the total risk exposure amount calculated in accordance with Article 92(3) of Regulation (EU) No 575/2013 and the buffer assigned to each sub-category shall increase in gradients of 0,5 % of the total risk exposure amount calculated in accordance with Article 92(3) of Regulation (EU) No 575/2013 up to and including the fourth sub-category. The highest sub-category of the G-SII buffer shall be subject to a buffer of 3,5 % of the total risk exposure amount calculated in accordance with Article 92(3) of Regulation (EU) No 575/2013.
10. Without prejudice to paragraphs 1 and 9, the competent authority or the designated authority may, in the exercise of sound supervisory judgment:
(a) re- allocate a G-SII from a lower sub-category to a higher sub-category;
(b) allocate an entity as referred to in paragraph 1 that has an overall score that is lower than the cut-off score of the lowest sub-category to that sub-category or to a higher sub-category, thereby designating it as a G-SII.
11. Where the competent authority or the designated authority takes a decision in accordance with paragraph 10(b), it shall notify EBA accordingly, providing reasons.
12. The competent authority or the designated authority shall notify the names of the G-SIIs and O-SIIs and the respective sub-category to which each G-SII is allocated, to the Commission, the ESRB and EBA, and shall disclose their names to the public. The competent authorities or designated authorities shall disclose to the public the sub-category to which each G-SII is allocated.
The competent authority or the designated authority shall review annually the identification of G-SIIs and O-SIIs and the G-SII allocation into the respective sub-categories and report the result to the systemically important institution concerned, to the Commission, the ESRB and EBA and disclose the updated list of identified systemically important institutions to the public and shall disclose to the public the sub-category into which each identified G-SII is allocated.
14. Where a group, on a consolidated basis, is subject to the following, the higher buffer shall apply in each case:
(a) a G-SII buffer and an O-SII buffer;
(b) a G-SII buffer, an O-SII buffer and a systemic risk buffer in accordance with Article 133.
Where an institution, on an individual or sub-consolidated basis is subject to an O-SII buffer and a systemic risk buffer in accordance with Article 133, the higher of the two shall apply.
15. Notwithstanding paragraph 14, where the systemic risk buffer applies to all exposures located in the Member State that sets that buffer to address the macroprudential risk of that Member State, but does not apply to exposures outside the Member State, that systemic risk buffer shall be cumulative with the O-SII or G-SII buffer that is applied in accordance with this Article.
