Duration and convexity are two tools used to manage the risk exposure of fixed-income investments. Duration measures the bond's sensitivity to interest rate changes.

How to Calculate Convexity in Excel To calculate convexity in Excel, begin by designating a different pair of cells for each of the variables identified in the formula. The first cell acts as the ...

It turns out that all tax-exempt munis exhibit negative convexity near par, even if they are not callable. The driver of this phenomenon is the so-called de minimis tax effect.

A novel method based on Malliavin calculus is developed to approximate convexity adjustments in a general interest rate model. Convexity adjustments are calculated for commonly traded interest rate ...
