Abstract

The purpose of this paper is to provide a new set of tools for policy makers at central banks. Based on the Garman-Kohlhagen formula for currency options, this research extends it with the Taylor-rule expression used for inflation targeting, thus obtaining the corresponding Call and Put options and higher-degree partial derivatives known as "Greeks" for key variables such as the policy target domestic interest rate and the output gap.
