What's the hardest (longest-running) financial calculation?

Thanks for the links, EdS2, people here are sure to enjoy them.

For built-in functionality, you can be sure that the IRR computation is the hardest, as it involves finding a root of a usually large polynomial (degree 20 or more is typical and up to ~1,500^th degree is possible on such a small calculator, see the details here).

And as I said, for financial calculations complexity can be enormous. Have a look at these two (no need to read them, just have a look from top to bottom to ascertain the complexity):

      Pricing the zero-coupon bond (pricing of interest rate derivatives)

      Qualitative behaviour of a financial dynamical system (variables are interest rate, investment demand, price index and average profit margin)
