This study divides the world into currency zones according to the co-movement of each currency with the key currencies. The dollar zone groups economies that produce well over half of global GDP. The euro zone now includes almost all of Europe and some commodity producers, but remains less than...

The traditional approach to international finance is to view capital flows as the financial counterpart to savings and investment decisions, assuming further that the GDP boundary defines both the decision-making unit and the currency area. This "triple coincidence" of GDP area, decision-making...

We propose a "debt view" to explain the dominant international role of the dollar. We develop an international general equilibrium model in which firms optimally choose the currency composition of their nominal debt. Expansionary monetary policy in downturns prevents Fisherian debt deflation...

This study investigates how variation in the determinants of the renminbi's daily fixing since the August 2015 exchange rate reform maps on to variation in the co- movement of the renminbi with regional and other emerging market currencies. We first identify three post-reform periods of RMB...

We develop a general equilibrium model with intermediaries at the heart of international financial markets. In our model, intermediaries bargain with their customers and extract rents for providing access to foreign claims. The behavior of intermediaries, by tilting state prices, generates an...

We employ a rarely available high-frequency micro dataset to study the impact of foreign exchange intervention on domestic credit growth. We find that sterilised purchases of dollars by the central bank dampens the flow of new domestic corporate loans in Colombia. Slowing the pace of currency...

Official reserve managers have a big stake in the debate over safe assets: their portfolios just about define such assets. This paper conveys the message that reserve managers need not worry about a shortage of safe assets. The debate turns first on whether demand for dollar safe assets will...

Is systematic monetary policy a driver of the forward premium puzzle, i.e. the tendency of high interest-rate currencies to appreciate, thus strongly violating Uncovered Interest Parity (UIP)? We address this question by studying a battery of monetary policy rules in a small open economy that is...

We investigate global factors associated with bank capital flows. We formulate a model of the international banking system where global banks interact with local banks. The solution highlights the bank leverage cycle as the determinant of the transmission of financial conditions across borders...

One area where international monetary cooperation has failed is in the role of surplus or creditor countries in limiting or in correcting external imbalances. The stock dimensions of such imbalances - net external positions, leverage in national balance sheets, currency/maturity mismatches, the...
