Why to use ultibi

• Blazingly fast.

Why to use ultibi for FRTB

• The calculation goes as per FRTB SA Paper (Note: ultibi is not (yet) certified by ISDA. Always check the output against your own interpretation of the regulation) and aims to be fully compliant(although not certified). ultibi supports CRR2 parameter set out of the box. Switch between the two is as easy as setting jurisdiction to CRR2 or BCBS.

• ultibi is very flexible and allows you to override any of the prescribed parameters (such as girr_delta_rho_infl_base_low) via calc_params argument. This essentually means that you can define your own parameter sets as per any regulatory requirements (eg non BCBS/CRR2). This also means that you can stress test against changes in the values of the prescribed (aka hard coded by ISDA) parameters.
