Credit risk modelling using Merton's Model has long been the go-to framework for assessing default probability in loans or bonds.However, in today's volatile financial markets, static assumptions and unstructured data make Merton's Model less reliable.To overcome these limitations, integrating generative AI and hybrid models can provide a fresh approach to credit risk modelling.These techniques involve processing unstructured data, generating realistic stress scenarios, and combining structural models with data-driven methods.
