Currency Forwards: Econ vs. Deriv

We are given two formulas for currency forwards, one in ECON and one in DERIV. The two should yield the same number, right?

Not exactly.

The Econ formula uses LIBOR (nominal) rates, whereas the Derivatives uses effective rates.

However, once you account for the difference in the rates, they give the same answer.

Got it. Thanks!

My pleasure.
