VAST™ (Variable Assumptions Set Tool) is a mortgage risk analytical software designed for evaluating the price performance of Mortgage Servicing Rights (MSR), Whole Loans, and associated Hedge Instruments. It offers both prospective and retrospective analysis capabilities for mortgage asset classes across residential and commercial sectors, as well as long-dated interest rate derivatives. The software enhances users' understanding of market value risk, allowing control over model parameters such as term structure shape, basis spreads, forward time periods, volatility surfaces, and prepayment, foreclosure, and loss simulation models. VAST™ facilitates integration with various data sources, enables the storage of multiple scenarios for Yield Curve Environment (YCE) shocking, and can produce base and scenario cash flows. Its Interest Rate Model features a rich volatility surface of ATM Swaptions, and MIAC's calibration of market volatility structure promotes a zero-calibration error rate through reliable Monte Carlo paths and forward curve generation, demonstrating a strong correlation between the market and the model. All software solutions include comprehensive onboarding, onsite and online support with extended working hours, and benefit from the company's deep industry expertise.
