Interest is not a derivative of a debt instrument such as an obligation.

The most common example quoted is slowing the rise of the rate of increase in inflation. Inflation is change in price, i.e. first derivative.

Similarly, finance people don’t consider interest rates/yields to be derivatives. So, on a bond “duration” is the first derivative of price with respect to yield, and “convexity” is the second derivative.
