Calculation of the capital requirements for structural FX risk

In the context of article 352.2,  when there is an investment in a subsidiary denominated in foreign currency and this subsidiary has invested in other subsidiary denominated in the same foreign currency must this exposure be always exempted from capital requirements calculation?

EBA explains in EBA Guidelines on the treatment of structural FX under Article 352(2) of Regulation (EU) No 575/2013 (CRR) page 97 example 7 a case where a company invests in a company denominated in a foreign currency, and the guidelines determine that the maximum open position must be 0 because the CET1 of the institution is not sensitive to changes in the FX rate.  Following this criteria, in the case of a subsidiary which invest into another subsidiary  denominated in foreign currency which is the currency of its main operations must be the same conclusion, the net open positions must be 0.  For example: Parent co is denominated in EUR and invests in subsidiary A which is denominated in USD. Subsidiary A invests in subsidiary B which is also denominated in USD. Parent co Monetary Assets in EUR                              30.000 Historical Assets in USD  subsidiary A    1.000 Monetary Liabilities in EUR                        28.000 CET1 in EUR                                                   3.000   Subsidiary A Monetary Assets in USD                                            10.000 Historical Assets in USD subsidiary B                    1.000 Monetary Liabilities in USD                                       10.000 CET1 in USD                                                                  1.000   Subsidiary B Monetary Assets in USD                                            4.000 Monetary Liabilities in USD                                       3.000 CET1 in USD                                                                  1.000
