Pricing Options on Interest Rate Instruments

Interest rate modeling has quickly become one of the main areas in financial markets. The models have grown in sophistication in response to development of new products and structures. Almost all pricing of securities and the risk management function including marking-to-market relies on interest rate modeling of some description. The information on interest rates, usually conveyed from the options markets, is important for other markets as well, such as the more established credit risk, commodities, equities, and the more recent ones such as inflation derivatives and insurance derivatives. Many models have been developed over the years, and their advantages and disadvantages should be appreciated and understood when they are applied.
