Article 8 Definition of the scenario matrix according to the scenario approach
- (1)
For each distinct underlying type, as referred to in Article 5(3), an institution shall define a scenario matrix which contains a set of scenarios.
- (2)
The first dimension of the scenario matrix shall be the price changes in the underlying above and below its current value. That range of changes shall consist of the following:
- (a)
for interest rate options or warrants, plus/minus the assumed change in interest rates set out in column 5 of Table 2 of Article 339 of Regulation (EU) No 575/2013;
- (b)
for options or warrants on equity or equity indices, plus/minus the weighting provided in Article 343 of Regulation (EU) No 575/2013;
- (c)
for foreign exchange and gold options or warrants, plus/minus the weighting indicated in Article 351 of Regulation (EU) No 575/2013 or, where appropriate, plus/minus the weighting indicated in Article 354 of Regulation (EU) No 575/2013;
- (d)
for commodity options (warrants), plus/minus the weighting indicated in point (a) of Article 360(1) of Regulation (EU) No 575/2013.
- (a)
- (3)
The price change scenarios in the underlying shall be defined by a grid of at least seven points which includes the current observation and divides the range indicated in paragraph 2 in equally spaced intervals.
- (4)
The second dimension of the scenario matrix shall be defined by volatility changes. The range of changes in volatilities shall be between plus/minus 25 % of the implied volatility, where implied volatility shall be understood as referred to in Article 4(2). That range shall be divided into a grid of at least three points which include a 0 % change and where the range is divided into equally spaced intervals.
- (5)
The scenario matrix is determined by all possible combinations of points, as referred to in paragraphs 3 and 4. Each combination shall constitute a single scenario.
