Section 1

General provisions

Article 325c

Scope and structure of the alternative standardised approach

1. The alternative standardised approach as set out in this Chapter shall be used only for the purposes of the reporting requirement laid down in Article 430b(1).

2. Institutions shall calculate the own funds requirements for market risk in accordance with the alternative standardised approach for a portfolio of trading book positions or non-trading book positions that are subject to foreign exchange or commodity risk as the sum of the following three components: (a) the own funds requirement under the sensitivities-based method set out in Section 2; (b) the own funds requirement for the default risk set out in Section 5 which is only applicable to the trading book positions referred to in that Section; (c) the own funds requirement for residual risks set out in Section 4 which is only applicable to the trading book positions referred to in that Section.







Section 2

Sensitivities-based method for calculating the own funds requirement

Article 325d

Definitions

For the purposes of this Chapter, the following definitions apply:

(1) ‘risk class’ means one of the following seven categories: (i) general interest rate risk; (ii) credit spread risk (CSR) for non-securitisation; (iii) credit spread risk for securitisation not included in the alternative correlation trading portfolio (non-ACTP CSR); (iv) credit spread risk for securitisation included in the alternative correlation trading portfolio (ACTP CSR); (v) equity risk; (vi) commodity risk; (vii) foreign exchange risk;

(2) ‘sensitivity’ means the relative change in the value of a position, as a result of a change in the value of one of the relevant risk factors of the position, calculated with the institution's pricing model in accordance with Subsection 2 of Section 3;

(3) ‘bucket’ means a sub-category of positions within one risk class with a similar risk profile to which a risk weight as defined in Subsection 1 of Section 3 is assigned.

Article 325e

Components of the sensitivities-based method

1. Institutions shall calculate the own funds requirement for market risk under the sensitivities-based method by aggregating the following three own funds requirements in accordance with Article 325h: (a) own funds requirements for delta risk which capture the risk of changes in the value of an instrument due to movements in its non-volatility related risk factors; (b) own funds requirements for vega risk which capture the risk of changes in the value of an instrument due to movements in its volatility-related risk factors; (c) own funds requirements for curvature risk which capture the risk of changes in the value of an instrument due to movements in the main non-volatility related risk factors not captured by the own funds requirements for delta risk.

2. For the purpose of the calculation referred to in paragraph 1, (a) all the positions of instruments with optionality shall be subject to the own funds requirements referred to in points (a), (b) and (c) of paragraph 1; (b) all the positions of instruments without optionality shall only be subject to the own funds requirements referred to in point (a) of paragraph 1.

For the purposes of this Chapter, instruments with optionality include, among others: calls, puts, caps, floors, swap options, barrier options and exotic options. Embedded options, such as prepayment or behavioural options, shall be considered to be stand-alone positions in options for the purpose of calculating the own funds requirements for market risk.

For the purposes of this Chapter, instruments whose cash flows can be written as a linear function of the underlying's notional amount shall be considered to be instruments without optionality.

Article 325f

Own funds requirements for delta and vega risks

1. Institutions shall apply the delta and vega risk factors described in Subsection 1 of Section 3 to calculate the own funds requirements for delta and vega risks.

2. Institutions shall apply the process set out in paragraphs 3 to 8 to calculate own funds requirements for delta and vega risks.

3. For each risk class, the sensitivity of all instruments in scope of the own funds requirements for delta or vega risks to each of the applicable delta or vega risk factors included in that risk class shall be calculated by using the corresponding formulas in Subsection 2 of Section 3. If the value of an instrument depends on several risk factors, the sensitivity shall be determined separately for each risk factor.

4. Sensitivities shall be assigned to one of the buckets ‘b’ within each risk class.

5. Within each bucket ‘b’, the positive and negative sensitivities to the same risk factor shall be netted, giving rise to net sensitivities (s k ) to each risk factor k within a bucket.

6. The net sensitivities to each risk factor within each bucket shall be multiplied by the corresponding risk weights set out in Section 6, giving rise to weighted sensitivities to each risk factor within that bucket in accordance with the following formula: WS k = RW k · s k where: WSk = the weighted sensitivities; RWk = the risk weights; and sk = the risk factor.

7. The weighted sensitivities to the different risk factors within each bucket shall be aggregated in accordance with the formula below, where the quantity within the square root function is floored at zero, giving rise to the bucket-specific sensitivity. The corresponding correlations for weighted sensitivities within the same bucket (ρkl), set out in Section 6, shall be used. where: Kb = the bucket-specific sensitivity; and WS = the weighted sensitivities.

8. The bucket-specific sensitivity shall be calculated for each bucket within a risk class in accordance with paragraphs 5, 6 and 7. Once the bucket-specific sensitivity has been calculated for all buckets, weighted sensitivities to all risk factors across buckets shall be aggregated in accordance with the formula below, using the corresponding correlations γbc for weighted sensitivities in different buckets set out in Section 6, giving rise to the risk-class specific own funds requirement for delta or vega risk: where: ▼C2 Sb = Σk WSk for all risk factors in bucket b and Sc = Σk WSk in bucket c; where those values for Sb and Sc produce a negative number for the overall sum of , the institution shall calculate the risk-class specific own funds requirements for delta or vega risk using an alternative specification whereby ▼B Sb = max [min (Σk WSk, Kb), – Kb] for all risk factors in bucket b and Sc = max [min (Σk WSk, Kc), – Kc] for all risk factors in bucket c.

The risk-class specific own funds requirements for delta or vega risk shall be calculated for each risk class in accordance with paragraphs 1 to 8.

Aggregation of risk-class specific own funds requirements for delta, vega and curvature risks

1. Institutions shall aggregate risk-class specific own funds requirements for delta, vega and curvature risks in accordance with the process set out in paragraphs 2, 3 and 4.

2. The process to calculate the risk-class specific own funds requirements for delta, vega and curvature risks described in Articles 325f and 325g shall be performed three times per risk class, each time using a different set of correlation parameters ρkl (correlation between risk factors within a bucket) and γbc (correlation between buckets within a risk class). Each of those three sets shall correspond to a different scenario, as follows: (a) the medium correlations scenario, whereby the correlation parameters ρkl and γbc remain unchanged from those specified in Section 6; (b) the high correlations scenario, whereby the correlation parameters ρkl and γbc that are specified in Section 6 shall be uniformly multiplied by 1,25, with ρkl and γbc subject to a cap at 100 %; (c) the low correlations scenario shall be specified in the delegated act referred to in Article 461a.

3. Institutions shall calculate the sum of the delta, vega and curvature risk-class specific own funds requirements for each scenario to determine three scenario-specific, own funds requirements.

4. The own funds requirement under the sensitivities-based method shall be the highest of the three scenario-specific own funds requirements referred to in paragraph 3.

Treatment of index instruments and multi-underlying options

Institutions shall treat the index instruments and multi-underlying options in accordance with the delegated act referred to in Article 461a.

Article 325j

Treatment of collective investment undertakings

Article 325k

Underwriting positions

1. Institutions may use the process set out in this Article for calculating the own funds requirements for market risk of underwriting positions of debt or equity instruments.

2. Institutions shall apply one of the appropriate multiplying factors listed in Table 1 to the net sensitivities of all the underwriting positions in each individual issuer, excluding the underwriting positions which are subscribed or sub-underwritten by third parties on the basis of formal agreements, and calculate the own funds requirements for market risk in accordance with the approach set out in this Chapter on the basis of the adjusted net sensitivities.

3. Institutions shall notify the competent authorities of the application of the process set out in this Article.







Section 3

Risk factor and sensitivity definitions







Subsection 1

Risk factor definitions

Article 325l

General interest rate risk factors

1. For all general interest rate risk factors, including inflation risk and cross-currency basis risk, there shall be one bucket per currency, each containing different types of risk factor.

The delta general interest rate risk factors applicable to interest rate-sensitive instruments shall be the relevant risk-free rates per currency and per each of the following maturities: 0,25 years, 0,5 years, 1 year, 2 years, 3 years, 5 years, 10 years, 15 years, 20 years, 30 years. Institutions shall assign risk factors to the specified vertices by linear interpolation or by using a method that is most consistent with the pricing functions used by the independent risk control function of the institution to report market risk or profits and losses to senior management.

2. Institutions shall obtain the risk-free rates per currency from money market instruments held in the trading book of the institution that have the lowest credit risk, such as overnight index swaps.

3. Where institutions cannot apply the approach referred to in paragraph 2, the risk-free rates shall be based on one or more market-implied swap curves used by the institution to mark positions to market, such as the interbank offered rate swap curves.

Where the data on market-implied swap curves described in paragraph 2 and the first subparagraph of this paragraph are insufficient, the risk-free rates may be derived from the most appropriate sovereign bond curve for a given currency.

Where institutions use the general interest rate risk factors derived in accordance with the procedure set out in the second subparagraph of this paragraph for sovereign debt instruments, the sovereign debt instrument shall not be exempted from the own funds requirements for credit spread risk. In those cases, where it is not possible to disentangle the risk-free rate from the credit spread component, the sensitivity to the risk factor shall be allocated both to the general interest rate risk and to credit spread risk classes.

4. In the case of general interest rate risk factors, each currency shall constitute a separate bucket. Institutions shall assign risk factors within the same bucket, but with different maturities, a different risk weight, in accordance with Section 6.

Institutions shall apply additional risk factors for inflation risk to debt instruments whose cash flows are functionally dependent on inflation rates. Those additional risk factors shall consist of one vector of market-implied inflation rates of different maturities per currency. For each instrument, the vector shall contain as many components as there are inflation rates used as variables by the institution's pricing model for that instrument.

5. Institutions shall calculate the sensitivity of the instrument to the additional risk factor for inflation risk referred to in paragraph 4 as the change in the value of the instrument, according to its pricing model, as a result of a 1 basis point shift in each of the components of the vector. Each currency shall constitute a separate bucket. Within each bucket, institutions shall treat inflation as a single risk factor, regardless of the number of components of each vector. Institutions shall offset all sensitivities to inflation within a bucket, calculated as described in this paragraph, in order to give rise to a single net sensitivity per bucket.

6. Debt instruments that involve payments in different currencies shall also be subject to cross-currency basis risk between those currencies. For the purposes of the sensitivities-based method, the risk factors to be applied by institutions shall be the cross-currency basis risk of each currency over either US dollar or euro. Institutions shall compute cross currency bases that do not relate to either basis over US dollar or basis over euro either on ‘basis over US dollar’ or ‘basis over euro’.

Each cross-currency basis risk factor shall consist of one vector of cross-currency basis of different maturities per currency. For each debt instrument, the vector shall contain as many components as there are cross-currency bases used as variables by the institution's pricing model for that instrument. Each currency shall constitute a different bucket.

Institutions shall calculate the sensitivity of the instrument to the cross-currency basis risk factor as the change in the value of the instrument, according to its pricing model, as a result of a 1 basis point shift in each of the components of the vector. Each currency shall constitute a separate bucket. Within each bucket there shall be two possible distinct risk factors: basis over euro and basis over US dollar, regardless of the number of components there are in each cross-currency basis vector. The maximum number of net sensitivities per bucket shall be two.

7. The vega general interest rate risk factors applicable to options with underlyings that are sensitive to general interest rate shall be the implied volatilities of the relevant risk-free rates as described in paragraphs 2 and 3, which shall be assigned to buckets depending on the currency and mapped to the following maturities within each bucket: 0,5 years, 1 year, 3 years, 5 years, 10 years. There shall be one bucket per currency.

For netting purposes, institutions shall consider implied volatilities linked to the same risk-free rates and mapped to the same maturities to constitute the same risk factor.

Where institutions map implied volatilities to the maturities as referred to in this paragraph, the following requirements shall apply:

(a) where the maturity of the option is aligned with the maturity of the underlying, a single risk factor shall be considered, which shall be mapped to that maturity;

(b) where the maturity of the option is shorter than the maturity of the underlying, the following risk factors shall be considered as follows: (i) the first risk factor shall be mapped to the maturity of the option; (ii) the second risk factor shall be mapped to the residual maturity of the underlying of the option at the expiry date of the option.

8. The curvature general interest rate risk factors to be applied by institutions shall consist of one vector of risk-free rates, representing a specific risk-free yield curve, per currency. Each currency shall constitute a different bucket. For each instrument, the vector shall contain as many components as there are different maturities of risk-free rates used as variables by the institution's pricing model for that instrument.

9. Institutions shall calculate the sensitivity of the instrument to each risk factor used in the curvature risk formula in accordance with Article 325g. For the purposes of the curvature risk, institutions shall consider vectors corresponding to different yield curves and with a different number of components as the same risk factor, provided that those vectors correspond to the same currency. Institutions shall offset sensitivities to the same risk factor. There shall be only one net sensitivity per bucket.

There shall be no curvature risk own funds requirements for inflation and cross currency basis risks.

Article 325m

Credit spread risk factors for non-securitisation

1. The delta credit spread risk factors to be applied by institutions to non-securitisation instruments that are sensitive to credit spread shall be the issuer credit spread rates of those instruments, inferred from the relevant debt instruments and credit default swaps, and mapped to each of the following maturities: 0,5 years, 1 year, 3 years, 5 years, 10 years. Institutions shall apply one risk factor per issuer and maturity, regardless of whether those issuer credit spread rates are inferred from debt instruments or credit default swaps. The buckets shall be sector buckets, as referred to in Section 6, and each bucket shall include all the risk factors allocated to the relevant sector.

2. The vega credit spread risk factors to be applied by institutions to options with non-securitisation underlyings that are sensitive to credit spread shall be the implied volatilities of the underlying's issuer credit spread rates inferred as laid down in paragraph 1, which shall be mapped to the following maturities in accordance with the maturity of the option subject to own funds requirements: 0,5 years, 1 year, 3 years, 5 years, 10 years. The same buckets shall be used as the buckets that were used for the delta credit spread risk for non-securitisation.

3. The curvature credit spread risk factors to be applied by institutions to non-securitisation instruments shall consist of one vector of credit spread rates, representing a credit spread curve specific to the issuer. For each instrument, the vector shall contain as many components as there are different maturities of credit spread rates used as variables in the institution's pricing model for that instrument. The same buckets shall be used as the buckets that were used for the delta credit spread risk for non-securitisation.

4. Institutions shall calculate the sensitivity of the instrument to each risk factor used in the curvature risk formula in accordance with Article 325g. For the purposes of the curvature risk, institutions shall consider vectors inferred from either relevant debt instruments or credit default swaps and with a different number of components as the same risk factor, provided that those vectors correspond to the same issuer.

Article 325n

By way of derogation from paragraph 1, subject to the permission of the competent authorities, an institution may use alternative definitions of delta risk sensitivities in the calculation of the own funds requirements of a trading book position under this Chapter, provided that the institution meets all the following conditions: (a) those alternative definitions are used for internal risk management purposes and for the reporting of profits and losses to senior management by an independent risk control unit within the institution; (b) the institution demonstrates that those alternative definitions are more appropriate for capturing the sensitivities for the position than are the formulas set out in this Subsection, and that the resulting sensitivities do not materially differ from those formulas.

6. By way of derogation from paragraph 1, subject to the permission of the competent authorities, an institution may calculate vega sensitivities on the basis of a linear transformation of alternative definitions of sensitivities in the calculation of the own funds requirements of a trading book position under this Chapter, provided that the institution meets both the following conditions: (a) those alternative definitions are used for internal risk management purposes and for the reporting of profits and losses to senior management by an independent risk control unit within the institution; (b) the institution demonstrates that those alternative definitions are more appropriate for capturing the sensitivities for the position than are the formulas set out in this Subsection, and that the linear transformation referred to in the first subparagraph reflects a vega risk sensitivity.

Article 325u

Own funds requirements for residual risks

1. In addition to the own funds requirements for market risk set out in Section 2, institutions shall apply additional own funds requirements to instruments exposed to residual risks in accordance with this Article.

2. Instruments are considered to be exposed to residual risks where they meet any of the following conditions: (a) the instrument references an exotic underlying, which, for the purposes of this Chapter, means a trading book instrument referencing an underlying exposure that is not in the scope of the delta, vega or curvature risk treatments under the sensitivities-based method laid down in Section 2 or the own funds requirements for the default risk set out in Section 5; (b) the instrument is an instrument bearing other residual risks, which, for the purposes of this Chapter, means any of the following instruments: (i) instruments that are subject to the own funds requirements for vega and curvature risk under the sensitivities-based method set out in Section 2 and that generate pay-offs that cannot be replicated as a finite linear combination of plain-vanilla options with a single underlying equity price, commodity price, exchange rate, bond price, credit default swap price or interest rate swap; (ii) instruments that are positions that are included in the ACTP referred to in Article 325(6); hedges that are included in that ACTP, as referred to in Article 325(8), shall not be considered.

3. Institutions shall calculate the additional own funds requirements referred to in paragraph 1 as the sum of gross notional amounts of the instruments referred to in paragraph 2, multiplied by the following risk weights: (a) 1,0 % in the case of instruments referred to in point (a) of paragraph 2; (b) 0,1 % in the case of instruments referred to in point (b) of paragraph 2.

4. By way of derogation from paragraph 1, institution shall not apply the own funds requirement for residual risks to an instrument that meets any of the following conditions: (a) the instrument is listed on a recognised exchange; (b) the instrument is eligible for central clearing in accordance with Regulation (EU) No 648/2012; (c) the instrument perfectly offsets the market risk of another position in the trading book, in which case the two perfectly matching trading book positions shall be exempted from the own funds requirement for residual risks.

5. EBA shall develop draft regulatory technical standards to specify what an exotic underlying is and which instruments are instruments bearing residual risks for the purposes of paragraph 2.

When developing those draft regulatory technical standards, EBA shall examine whether longevity risk, weather, natural disasters and future realised volatility should be considered as exotic underlyings.

EBA shall submit those draft regulatory technical standards to the Commission by 28 June 2021.

Power is delegated to the Commission to supplement this Regulation by adopting the regulatory technical standards referred to in the first subparagraph in accordance with Articles 10 to 14 of Regulation (EU) No 1093/2010.







Section 5

Own funds requirements for the default risk

Article 325v

Definitions and general provisions

1. For the purposes of this Section, the following definitions apply: (a) ‘short exposure’ means that the default of an issuer or group of issuers leads to a gain for the institution, regardless of the type of instrument or transaction creating the exposure; (b) ‘long exposure’ means that the default of an issuer or group of issuers leads to a loss for the institution, regardless of the type of instrument or transaction creating the exposure; (c) ‘gross jump-to-default (gross JTD) amount’ means the estimated size of the loss or gain that the default of the obligor would produce for a specific exposure; (d) ‘net jump-to-default (net JTD) amount’ means the estimated size of the loss or gain that an institution would incur due to the default of an obligor, after offsetting between gross JTD amounts has taken place, (e) ‘loss given default’ or ‘LGD’ means the loss given default of the obligor on an instrument issued by that obligor expressed as a share of the notional amount of the instrument; (f) ‘default risk weight’ means the percentage representing the estimated probability of the default of each obligor, according to the creditworthiness of that obligor.

2. Own funds requirements for the default risk shall apply to debt and equity instruments, to derivative instruments having those instruments as underlyings and to derivatives, the pay-offs or fair values of which are affected by the default of an obligor other than the counterparty to the derivative instrument itself. Institutions shall calculate default risk requirements separately for each of the following types of instruments: non-securitisations, securitisations that are not included in the ACTP, and securitisations that are included in the ACTP. The final own funds requirements for the default risk to be applied by institutions shall be the sum of those three components.







Subsection 1

Own funds requirements for the default risk for non-securitisations

Article 325w

Gross jump-to-default amounts

1. Institutions shall calculate the gross JTD amounts for each long exposure to debt instruments as follows: JTD long = max {LGD V notional + P&L long + Adjustment long ; 0} where: JTDlong = the gross JTD amount for the long exposure; ▼C2 Vnotional = the notional amount of the instrument from which the exposure arises; P&Llong = a term which adjusts for gains or losses already accounted for by the institution due to changes in the fair value of the instrument creating the long exposure; gains shall enter into the formula with a positive sign and losses shall enter into the formula with a negative sign; and Adjustmentlong = where the instrument from which the exposure arises is a derivative instrument, the amount by which, due to the structure of the derivative instrument, the institution's loss in the event of default would be increased or reduced relative to the full loss on the underlying instrument; increases shall enter into the formula with a positive sign and decreases shall enter into the formula with a negative sign. ▼B

2. Institutions shall calculate the gross JTD amounts for each short exposure to debt instruments as follows: JTD short = min {LGD V notional + P&L short + Adjustment short ; 0} where: JTDshort = the gross JTD amount for the short exposure; ▼C2 Vnotional = the notional amount of the instrument from which the exposure arises that shall enter into the formula with a negative sign; P&Lshort = a term which adjusts for gains or losses already accounted for by the institution due to changes in the fair value of the instrument creating the short exposure; gains shall enter into the formula with a positive sign and losses shall enter into the formula with a negative sign; and Adjustmentshort = where the instrument from which the exposure arises is a derivative instrument, the amount by which, due to the structure of the derivative instrument, the institution's gain in the event of default would be increased or reduced relative to the full loss on the underlying instrument; decreases shall enter into the formula with a positive sign and increases shall enter into the formula with a negative sign. ▼B

3. For the purposes of the calculation set out in paragraphs 1 and 2, the LGD for debt instruments to be applied by institutions shall be the following: (a) exposures to non-senior debt instruments shall be assigned an LGD of 100 %; (b) exposures to senior debt instruments shall be assigned an LGD of 75 %; (c) exposures to covered bonds, as referred to in Article 129, shall be assigned an LGD of 25 %.

▼C2

4. For the purposes of the calculations set out in paragraphs 1 and 2, notional amounts shall be determined as follows:

(a) in the case of a bond, the notional amount is the face value of the bond;

(b) in the case of a sold put option on a bond, the notional amount is the notional amount of the option; in the case of a bought call option on a bond, the notional amount is 0.

5. For exposures to equity instruments, institutions shall calculate the gross JTD amounts as follows: JTD long = max {LGD · V notional + P&L long + Adjustment long ; 0} JTD short = min {LGD · V notional + P&L short + Adjustment short ; 0} where: JTDlong = the gross JTD amount for the long exposure; Vnotional = the notional amount of the instrument from which the exposure arises; the notional amount is the fair value of the equity for cash equity instruments; for the JTDshort formula, the notional amount of the instrument shall enter into the formula with a negative sign; P&Llong = a term which adjusts for gains or losses already accounted for by the institution due to changes in the fair value of the instrument creating the long exposure; gains shall enter into the formula with a positive sign and losses shall enter into the formula with a negative sign; Adjustmentlong = the amount by which, due to the structure of the derivative instrument, the institution's loss in the event of default would be increased or reduced relative to the full loss on the underlying instrument; increases shall enter into the formula with a positive sign and decreases shall enter into the formula with a negative sign; JTDshort = the gross JTD amount for the short exposure; P&Lshort = a term which adjusts for gains or losses already accounted for by the institution due to changes in the fair value of the instrument creating the short exposure; gains shall enter into the formula with a positive sign and losses shall enter into the formula with a negative sign; and Adjustmentshort = the amount by which, due to the structure of the derivative instrument, the institution's gain in the event of default would be increased or reduced relative to the full loss on the underlying instrument; decreases shall enter into the formula with a positive sign and increases shall enter into the formula with a negative sign.

▼B

6. Institutions shall assign an LGD of 100 % to equity instruments for the purposes of the calculation set out in paragraph 5.

7. In the case of exposures to default risk arising from derivative instruments whose pay-offs in the event of default of the obligor are not related to the notional amount of a specific instrument issued by that obligor or to the LGD of the obligor or an instrument issued by that obligor, institutions shall use alternative methodologies to estimate the gross JTD amounts.

8. EBA shall develop draft regulatory technical standards to specify: ▼C2 (a) how institutions are to determine the components P&Llong, P&Lshort, Adjustmentlong and Adjustmentshort when calculating the JTD amounts for different types of instruments in accordance with this Article; ▼B (b) which alternative methodologies institutions are to use for the purposes of the estimation of gross JTD amounts referred to in paragraph 7. (c) the notional amounts of instruments other than the ones referred to in points (a) and (b) of paragraph 4.

EBA shall submit those draft regulatory technical standards to the Commission by 28 June 2021.

Power is delegated to the Commission to supplement this Regulation by adopting the regulatory technical standards referred to in the first subparagraph in accordance with Articles 10 to 14 of Regulation (EU) No 1093/2010.

Article 325x

Net jump-to-default amounts

1. Institutions shall calculate net JTD amounts by offsetting the gross JTD amounts of short exposures and long exposures. Offsetting shall only be possible between exposures to the same obligor where the short exposures have the same seniority as, or lower seniority than, the long exposures.

2. Offsetting shall be either full or partial, depending on the maturities of the offsetting exposures: (a) offsetting shall be full where all offsetting exposures have maturities of one year or more; (b) offsetting shall be partial where at least one of the offsetting exposures has a maturity of less than one year, in which case the size of the JTD amount of each exposure with a maturity of less than one year shall be multiplied by the ratio of the exposure's maturity relative to one year.

3. Where no offsetting is possible gross JTD amounts shall equal net JTD amounts in the case of exposures with maturities of one year or more. Gross JTD amounts with maturities of less than one year shall be multiplied by the ratio of the exposure's maturity relative to one year, with a floor of three months, to calculate net JTD amounts.

4. For the purposes of paragraphs 2 and 3, the maturities of the derivative contracts shall be considered, rather than those of their underlyings. Cash equity exposures shall be assigned a maturity of either one year or three months, at the institution's discretion.

Article 325y

Calculation of the own funds requirements for the default risk

1. Net JTD amounts, irrespective of the type of counterparty, shall be multiplied by the default risk weights that correspond to their credit quality, as specified in Table 2:



Table 2 Credit quality category Default risk weight Credit quality step 1 0,5 % Credit quality step 2 3 % Credit quality step 3 6 % Credit quality step 4 15 % Credit quality step 5 30 % Credit quality step 6 50 % Unrated 15 % Defaulted 100 %

2. Exposures which would receive a 0 % risk-weight under the Standardised Approach for credit risk in accordance with Chapter 2 of Title II shall receive a 0 % default risk weight for the own funds requirements for the default risk.

3. The weighted net JTD shall be allocated to the following buckets: corporates, sovereigns, and local governments/municipalities.

4. Weighted net JTD amounts shall be aggregated within each bucket, in accordance with the following formula: DRC b = max {(Σ i ∈ long RW i · net JTD i ) – WtS · (Σ i ∈ short RW i · |net JTD i |); 0} where: DRCb = the own funds requirement for the default risk for bucket b; i = the index that denotes an instrument belonging to bucket b; RWi = the risk weight; and WtS = a ratio recognising a benefit for hedging relationships within a bucket, which shall be calculated as follows:

For the purposes of calculating the DRCb and the WtS, the long positions and short positions shall be aggregated for all positions within a bucket, regardless of the credit quality step to which those positions are allocated, to produce the bucket-specific own funds requirements for the default risk.

5. The final own funds requirement for the default risk for non-securitisations shall be calculated as the simple sum of the bucket-level own funds requirements.







Subsection 2

Own funds requirements for the default risk for securitisations not included in the ACTP

Article 325z

Jump-to-default amounts

1. Gross jump-to-default amounts for securitisation exposures shall be their market value or, if their market value is not available, their fair value determined in accordance with the applicable accounting framework.

2. Net jump-to-default amounts shall be determined by offsetting long gross jump-to-default amounts and short gross jump-to-default amounts. Offsetting shall only be possible between securitisation exposures with the same underlying asset pool and belonging to the same tranche. No offsetting shall be permitted between securitisation exposures with different underlying asset pools, even where the attachment and detachment points are the same.

3. Where, by decomposing or combining existing securitisation exposures, other existing securitisation exposures can be perfectly replicated, except for the maturity dimension, the exposures resulting from that decomposition or combination may be used instead of the existing securitisation exposures for the purposes of offsetting.

4. Where, by decomposing or combining existing exposures in underlying names, the entire tranche structure of an existing securitisation exposure can be perfectly replicated, the exposures resulting from that decomposition or combination may be used instead of the existing securitisation exposures for the purposes of offsetting. Where underlying names are used in that manner, they shall be removed from the non-securitisation default risk treatment.

5. Article 325x shall apply to both existing securitisation exposures and to securitisation exposures used in accordance with paragraph 3 or 4 of this Article. The relevant maturities shall be those of the securitisation tranches.

Article 325aa

Calculation of the own funds requirement for the default risk for securitisations

1. Net JTD amounts of securitisation exposures shall be multiplied by 8 % of the risk weight that applies to the relevant securitisation exposure, including STS securitisations, in the non-trading book in accordance with the hierarchy of approaches set out in Section 3 of Chapter 5 of Title II and irrespective of the type of counterparty.

2. A maturity of one year shall be applied to all tranches, where risk weights are calculated in accordance with the SEC-IRBA and SEC-ERBA.

3. The risk-weighted JTD amounts for individual cash securitisation exposures shall be capped at the fair value of the position.

4. Risk-weighted net JTD amounts shall be assigned to the following buckets: (a) one common bucket for all corporates, regardless of the region; (b) 44 different buckets corresponding to one bucket per region for each of the 11 asset classes defined in the second subparagraph.

For the purposes of the first subparagraph, the 11 asset classes are ABCP, auto loans/leases, residential mortgage-backed securities (RMBS), credit cards, commercial mortgage-backed securities (CMBS), collateralised loan obligations, collateralised debt obligations squared (CDO-squared), small and medium-sized enterprises (SMEs), student loans, other retail, other wholesale. The four regions are Asia, Europe, North America, and rest of the world.

5. In order to assign a securitisation exposure to a bucket, institutions shall rely on a classification commonly used in the market. Institutions shall assign each securitisation exposure to only one of the buckets referred to in paragraph 4. Any securitisation exposure that an institution cannot assign to a bucket for an asset class or region shall be assigned to the asset class ‘other retail’ or ‘other wholesale’ or to the region ‘rest of the world’, respectively.

6. Weighted net JTD amounts shall be aggregated within each bucket in the same manner as for default risk of non-securitisation exposures, using the formula in Article 325y(4), resulting in the own funds requirement for the default risk for each bucket.

7. The final own funds requirement for the default risk for securitisations not included in the ACTP shall be calculated as the simple sum of the bucket-level own funds requirements.







Subsection 3

Own funds requirements for the default risk for securitisations included in the ACTP

Article 325ab

Scope

1. For the ACTP, the own funds requirements shall include the default risk for securitisation exposures and for non-securitisation hedges. Those hedges shall be removed from the default risk calculations for non-securitisation. There shall be no diversification benefit between the own funds requirements for the default risk for non-securitisations, the own funds requirements for the default risk for securitisations not included in the ACTP and own funds requirements for the default risk for securitisations included in the ACTP.

2. For traded non-securitisation credit and equity derivatives, JTD amounts by individual constituents shall be determined by applying a look-through approach.

Article 325ac

Jump-to-default amounts for the ACTP

1. For the purposes of this Article, the following definitions apply: (a) ‘decomposition with a valuation model’ means that a single name constituent of a securitisation is valued as the difference between the unconditional value of the securitisation and the conditional value of the securitisation assuming that single name defaults with an LGD of 100 %; (b) ‘replication’ means that the combination of individual securitisation index tranches are combined to replicate another tranche of the same index series, or to replicate an untranched position in the index series; (c) ‘decomposition’ means replicating an index by a securitisation of which the underlying exposures in the pool are identical to the single name exposures that compose the index.

2. The gross JTD amounts for securitisation exposures and non-securitisation exposures in the ACTP shall be their market value or, if their market value is not available, their fair value determined in accordance with the applicable accounting framework.

3. Nth-to-default products shall be treated as tranched products with the following attachment and detachment points: (a) attachment point = (N – 1) / Total Names; (b) detachment point = N / Total Names; where ‘Total Names’ shall be the total number of names in the underlying basket or pool.

4. Net JTD amounts shall be determined by offsetting long gross JTD amounts and short gross JTD amounts. Offsetting shall only be possible between exposures that are otherwise identical except for maturity. Offsetting shall only be possible as follows: (a) for indices, index tranches and bespoke tranches, offsetting shall be possible across maturities within the same index family, series and tranche, subject to the provisions on exposures of less than one year laid down in Article 325x; long gross JTD amounts and short gross JTD amounts that perfectly replicate each other may be offset through decomposition into single name equivalent exposures using a valuation model; in such cases, the sum of the gross JTD amounts of the single name equivalent exposures obtained through decomposition shall be equal to the gross JTD amount of the undecomposed exposure; (b) offsetting through decomposition as set out is point (a) shall not be allowed for resecuritisations or derivatives on securitisation; (c) for indices and index tranches, offsetting shall be possible across maturities within the same index family, series and tranche by replication or by decomposition; where the long exposures and short exposures are otherwise equivalent, apart from one residual component, offsetting shall be allowed and the net JTD amount shall reflect the residual exposure; (d) different tranches of the same index series, different series of the same index and different index families may not be used to offset each other.

Article 325ad

Calculation of the own funds requirements for the default risk for the ACTP

1. Net JTD amounts shall be multiplied by: (a) for tranched products, the default risk weights corresponding to their credit quality as specified in Article 325y(1) and (2); (b) for non-tranched products, the default risk weights referred to in Article 325aa(1).

2. Risk-weighted net JTD amounts shall be assigned to buckets that correspond to an index.

3. Weighted net JTD amounts shall be aggregated within each bucket in accordance with the following formula: DRC b = max {(Σ i ∈ long RW i · net JTD i ) – WtS ACTP · (Σ i ∈ short RW i · |net JTD i |); 0} where: DRCb = the own funds requirement for the default risk for bucket b; i = an instrument belonging to bucket b; and WtSACTP = the ratio recognising a benefit for hedging relationships within a bucket, which shall be calculated in accordance with the WtS formula set out in Article 325y(4), but using long positions and short positions across the entire ACTP and not just the positions in the particular bucket.

4. Institutions shall calculate the own funds requirements for the default risk for the ACTP by using the following formula: ▼B where: DRCACTP = the own funds requirement for the default risk for the ACTP; and DRCb = the own funds requirement for the default risk for bucket b.

2. After having verified institutions' compliance with the requirements set out in Articles 325bh, 325bi and 325bj, competent authorities shall grant permission to those institutions to calculate their own funds requirements for the portfolio of all positions assigned to trading desks by using their alternative internal models in accordance with Article 325ba, provided that all the following requirements are met: (a) the trading desks were established in accordance with Article 104b; (b) the institution has provided to the competent authority a rationale for the inclusion of the trading desks in the scope of the alternative internal model approach; (c) the trading desks have met the back-testing requirements referred to in Article 325bf(3) for the preceding year; (d) the institution has reported to its competent authorities the results of the profit and loss attribution (‘P&L attribution’) requirement for the trading desks set out in Article 325bg; (e) for trading desks that have been assigned at least one of those trading book positions referred to in Article 325bl, the trading desks fulfil the requirements set out in Article 325bm for the internal default risk model; (f) no securitisation or re-securitisation positions have been assigned to the trading desks.

For the purposes of point (b) of the first subparagraph of this paragraph, not including a trading desk in the scope of the alternative internal model approach shall not be motivated by the fact that the own funds requirement calculated under the alternative standardised approach set out in point (a) of Article 325(3) would be lower than the own funds requirement calculated under the alternative internal model approach.

3. Institutions that have received the permission to use the alternative internal model approach shall report to the competent authorities in accordance with Article 430b(3).

4. An institution that has been granted the permission referred to in paragraph 2 shall immediately notify its competent authorities that one of its trading desks no longer meets at least one of the requirements set out in that paragraph. That institution shall no longer be permitted to apply this Chapter to any of the positions assigned to that trading desk and shall calculate the own funds requirements for market risk in accordance with the approach set out in Chapter 1a for all the positions assigned to that trading desk from the earliest reporting date and until the institution demonstrates to the competent authorities that the trading desk again fulfils all the requirements set out in paragraph 2.

5. By way of derogation from paragraph 4, in extraordinary circumstances, competent authorities may permit an institution to continue using its alternative internal models for the purpose of calculating the own funds requirements for the market risk of a trading desk that no longer meets the conditions referred to in point (c) of paragraph 2 of this Article and in Article 325bg(1). When competent authorities exercise that discretion, they shall notify EBA and substantiate their decision.

6. For positions assigned to the trading desks for which an institution has not been granted permission as referred to in paragraph 2, the own funds requirements for market risk shall be calculated by that institution in accordance with Chapter 1a of this Title.

Institutions shall notify the competent authorities of all other extensions and changes to the use of the alternative internal models for which the institution has received permission.

8. EBA shall develop draft regulatory technical standards to specify: (a) the conditions for assessing the materiality of extensions and changes to the use of alternative internal models and changes to the subset of the modellable risk factors referred to in Article 325bc; (b) the assessment methodology under which competent authorities verify an institution's compliance with the requirements set out in Articles 325bh, 325bi, 325bn, 325bo and 325bp.

EBA shall submit those draft regulatory technical standards to the Commission by 28 June 2024.

Power is delegated to the Commission to supplement this Regulation by adopting the regulatory technical standards referred to in the first subparagraph in accordance with Articles 10 to 14 of Regulation (EU) No 1093/2010.

9. EBA shall develop draft regulatory technical standards to specify the extraordinary circumstances under which competent authorities may permit an institution: (a) to continue using its alternative internal models for the purpose of calculating the own funds requirements for the market risk of a trading desk that no longer meets the conditions referred to in point (c) of paragraph 2 of this Article and in Article 325bg(1); (b) to limit the add-on to the one resulting from overshootings under back-testing hypothetical changes.

EBA shall submit those draft regulatory technical standards to the Commission by 28 June 2024.
