Convexity measures the curvature of the price-yield curve. Positive convexity is beneficial as it means prices rise more when yields fall than they drop when yields rise.

Convexity Properties

  • - Higher convexity = Better protection against rate changes
  • - Convexity adds value (always positive adjustment)
  • - More important for large yield changes
  • - Callable bonds have negative convexity at low yields
