Open economy macroeconomics typically abstracts from portfolio structure. But the recent experience of financial globalization makes it important to understand the determinants and composition of gross country portfolios. This paper presents a simple approximation method for computing equilibrium financial portfolios in stochastic open economy macro models. The method is widely applicable, easy to implement, and delivers analytical solutions for optimal gross portfolio positions in any combination of types of assets. It can be used in models with any number of assets, whether markets are complete or incomplete, and can be applied to stochastic dynamic general equilibrium models of any dimension, so long as the model is amenable to a solution using standard approximation methods.
