Chebyshev for IMA-FRTB

In this talk we present results obtained within the systems of a tier-1 bank for a capital calculation within FRTB IMA, using Chebyshev tensors to massively accelerate and economise the calculation while retaining a high level of accuracy required by the regulation.

CVA and IMM for exotics and large portfolios

Computing CVA and/or IMM capital for exotic products is computationally challenging. It can also be difficult for large portfolios of vanilla products. In this video, we see how Chebyshev methods can increase the performance of existing Monte Carlo engines by orders of magnitude, facilitating the fast and efficient computation of CVA and IMM numbers for exotics and large portfolios
