This paper assesses whether the international monetary system is already tripolar and centred around the US dollar, the euro and the Chinese renminbi (RMB). It focuses on what we call China's “dominance hypothesis”, i.e. whether the renminbi is already the dominant currency in Asia, exerting...

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...

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 propose a new and time-varying optimum currency area (OCA) index for the euro area in assessing the evolution of the OCA properties of the monetary union from an international business cycle perspective. It is derived from the relative importance of symmetric vs. asymmetric shocks that result...

This paper provides insights into the determinants of currency choice in cross-border bank lending, such as bilateral distance, financial and trade linkages to issuer countries of major currencies, and invoicing currency patterns. Cross-border bank lending in US dollars, and particularly in...

This paper studies export adjustment to negative shocks in currency unions. I consider the hitherto ignored role of trade costs and taxes in internal devaluations, which have been brought to the fore of international policy during the recent euro periphery crisis. Trade costs can limit the...

In the policy debate on the effectiveness of the Global Financial Safety Net, concerns have been raised that expectations of adverse effects of IMF programmes may deter countries from asking for an IMF programme when they need one, a form of "IMF stigma". We explore the existence of IMF...

While the consequences and effectiveness of IMF conditionality have long been the focus of research, the possible negative impact of IMF conditionality on countries' willingness to ask for an IMF programme - often termed "IMF stigma" - has recently received attention particularly from policy...

We add to the literature on the influence of the global financial cycle (GFC) and gyrations in capital flows. First, we build a new measure of the GFC based on a structural factor approach, which incorporates theoretical priors in its definition. This measure can also be decomposed in a...

This paper quantifies the economic influence that shocks to EMU cohesion, which in turn reflect the incomplete nature of the monetary union, have on the rest of the world. Disentangling euro area stress shocks and global risk aversion shocks based on a combination of sign, magnitude and...
