The Vasicek Interest Rate Model is a mathematical model that tracks and models the evolution of interest rates. It is a one-factor short-rate model and assumes that the movement of interest rates can be modeled based on a single stochastic (or random) factor – the market risk Market Risk Market risk, also known as systematic risk, refers to the uncertainty associated with any investment • Market risk: the risk of unexpected changes in prices; • Credit risk: the risk of changes in value due to unexpected changes in credit quality, in particular if a counterparty defaults on one of their contractual obligations; • Liquidity risk: the risk that costs of adjusting ﬁnancial positions may increase sub-stantially; Vasicek model is a popular model that's used to measure Credit Risk as part of the Internal Ratings Based (IRB) approach.
