Are you sure you are doing it right? Interest rate curve construction: a review of the modern framework

About this event


The term structure of interest rates is central to many valuation or risk management models. However, the construction of interest rate curves is no trivial task, and demands an in-depth understanding of the interest rate derivatives markets. It is our experience that some financial institutions do not pay enough attention to that question, and end up using very simplistic approaches, such as linear interpolation on swap rates.

In this workshop, we examine the genesis of the need for a modern multi-curve bootstrapping framework, which takes into account the larger basis spreads and the collateral agreements, which are now widely used.

We then review several market standard approaches to construct interest rate curves under this modern framework, and show the pros and cons of each methodology. In particular, we suggest “optimal choices” depending on the targeted application.
