BGM Finding Skew May 2023 Update

We are pleased to announce the latest Finding Skew update for May 2023 is now available. A historical regression approach can be used to imply a market skew over a time series of pre-selected benchmark European swaption volatilities. Our paper outlines a process to estimate skew and applies this process to estimate recent skew patterns in both the CEV and Displaced Diffusion BGM model extensions based on recent 2023 market data.

Deposit Decay Modelling & Liquidity Stress Testing in PolyPaths

As a reminder, PolyPaths has a flexible framework for modelling Deposits where users can define a repricing formula based on either rate level or rate changes period-over-period. Alternatively, our Deposit Decay API allows users to integrate own internal models that forecast dynamic decay rates into PolyPaths. Once modelled, Deposits as well as other securities, can be run using PolyPaths ALM, which has several features including capabilities to measure liquidity risk. Within ALM users can customize Strategies which allow different outlooks on the balance sheet such as targeting growth levels, changing the mix of asset or liability types, or using strategies in forecasting liquidity stress.
