Secondly, the banks should calculate minimum capital required (Section A20.9 or A17.14 of guidelines in Appendix BR-3) by reference to the measure of market risk (i.e. specific risk plus general market risk) in accordance with the regulations contained in Section CA-1.4.

Thirdly, the amount resulting from the above requirement (Section A20.10 of guidelines in Appendix BR-3) should be multiplied by 28.57%. This is the minimum capital charge which should be supported by Tier 1 capital allocated to market risk weighted exposures (Section A20.12 of guidelines in Appendix BR-3); therefore, the balance amount in Tier 1 capital should be the amount allocated to support credit risk weighted assets (Section A20.6 of guidelines in Appendix BR-3).
