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...

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. The measure of a currency's global role is based...

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

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...

The paper provides a measure of exchange rate anchoring behavior across 149 emerging market and developing economies for the 1980-2010 period. An extension of the Frankel and Wei (2008) methodology is used to determine whether exchange rates are pegged or floating, and in the case of pegs, to...

The paper assesses the extent to which the Group of Seven (G7) has been successful in its management of major currencies since the 1970s. Using an event-study approach, the paper finds evidence that the G7 has been overall effective in moving the US dollar, yen and euro in the intended direction...

This paper examines the cross-dynamics of volatility term structures implied by foreign exchange options. The data used in the empirical analysis consist of daily observations of implied volatilities for OTC options on the euro, Japanese yen, British pound, Swiss franc, and Canadian dollar,...
