We empirically test Gabaix and Maggiori (2015)'s prediction that currencies are repriced by the country's external capital dependence when financial constraints of FX intermediaries change. Using solvency indicators, we develop a novel intermediary constraints index capturing riskbearing...

Pakistan's political economy has been characterized by some interesting and arguably unique features in recent decades. The combination of two stands out, in particular: (1) lifetime uncertainty for elected governments, and (2) a high degree of certainty that, due to reasons that are largely...

This paper examines whether and how expectations have contributed to the turbulent path of the Turkish lira since 2008. We derive uncertainty measures surrounding gross domestic product (GDP) growth, inflation, the interest rate, and exchange rates based on survey data from Consensus Economics....

The 1944 "Bretton Woods Agreement" gave birth to the new international financial system marked by the centrality of the US dollar which is a crucial pillar of the global power of the United States. Over the past eight decades, the asymmetry of the shrinking US economic weight in the world...

The rapid growth of international trade has promoted equally rapid economic development and globalization. It has also brought some problems. To earn foreign exchange from other countries, some countries have adopted export tax rebate policies and other subsidies to enhance the international...

Since the beginning of the 1980s, a continuous process of integration of national and regional markets into one global market for goods, services and capital can be noticed. Both economic theory and market practice indicate that the level of the exchange rate primarily depends on macroeconomic...

FX trade settlement data from CLS provides the most comprehensive view of the opaque market of OTC currency trades. We use the flows of investment funds and non-financial corporates and develop trading signals where the former reflects speculative strategies, while the latter trade for liquidity...

We show that FX interventions attenuate global financial cycle (GFC)’s spillovers. We exploit GFC shocks and Brazilian central bank interventions in FX derivatives using three matched administrative registers: credit, foreign credit to banks, and employer-employee. After U.S. Taper Tantrum...

Over 85% of all foreign exchange (FX) transactions involve the US dollar. I show that the US dollar dominates FX trading volume because of strategic avoidance of price impact. To demonstrate this, I leverage the fact that non-dollar currency pairs can be traded indirectly by using the US dollar...

Borrowing in foreign currency has historically induced a large currency mismatch on emerging economies' balance sheets, leading to financial instability and economic crises. Nonetheless, emerging market sovereigns still borrow a substantial amount in foreign currency. In fact, in this paper, we...

This paper explores the role of restrictions on the use of international reserves as economic sanctions. We develop a simple model of the strategic game between a sanctioning (creditor) country and a sanctioned (debtor) country. We show how the sanctioning country should impose restrictions...
