This paper develops a three‐currency model to study the determinants of the demand for assets and liabilites denominated in an international currency and to shed light on the prospects for the renminbi as a budding international currency. We show that interest rate differentials would be only one of the factors shaping the renminbi's position, while other factors, including the correlation between foreign countries' economic growth and their bilateral exchange rates against the renminbi, and the correlation between exchange rates of the renminbi with other international currencies, would also be important. A broad interpretation of these findings is that the renminbi will likely be attractive to investors from high‐income economies and fund‐raisers from emerging market economies.
