This paper presents a new concept - the global roles of currencies. The concept combines the domestic and international (cross-border) use of currencies and therefore captures the overall importance of different currencies in a globalised economy.

We analytically derive optimal central bank portfolios in a minimum variance framework with two assets and "transaction demands" caused by sudden stops in capital inflows. In this model, the transaction demands become less important relative to traditional portfolio objectives as debt to reserve...

The notable increase in international reserve holdings over the past decade and their use during the global financial crisis of 2008/2009 has sparked renewed interest in the analysis of the optimal level of reserve holdings, in particular in countries which are subject to sudden stops. Less...

In this paper we evaluate the predictive power of the three most popular equilibrium exchange rate concepts: Purchasing Power Parity (PPP), Behavioral Equilibrium Exchange Rate (BEER) and the Macroeconomic Balance (MB) approach. We show that there is a clear trade-off between storytelling and...

This paper focuses on changes in the currency options market’s assessment of likely future exchange rate developments around the times of official interventions in the JPY/USD exchange rate. We estimate the options-implied risk-neutral density functions (RNDs) using daily OTC quotes for...

While up to the late 1990s Japanese foreign exchange intervention was fully sterilized, Japanese monetary authorities left foreign exchange intervention unsterilized when Japan entered the liquidity trap in 1999. According to previous research on foreign exchange intervention, unsterilized...
