Why the dollar is—and will remain—the dominant global currency The U.S. dollar's dominance seems under threat. The near collapse of the U.S. financial system in 2008–2009, political paralysis that has blocked effective policymaking, and emerging competitors such as the Chinese renminbi have heightened speculation about the dollar’s looming displacement as the main reserve currency. Yet, as The Dollar Trap powerfully argues, the financial crisis, a dysfunctional international monetary system, and U.S. policies have paradoxically strengthened the dollar’s importance. Eswar Prasad examines how the dollar came to have a central role in the world economy and demonstrates that it will remain the cornerstone of global finance for the foreseeable future. Marshaling a range of arguments and data, and drawing on the latest research, Prasad shows why it will be difficult to dislodge the dollar-centric system. With vast amounts of foreign financial capital locked up in dollar assets, including U.S. government securities, other countries now have a strong incentive to prevent a dollar crash. Prasad takes the reader through key contemporary issues in international finance—including the growing economic influence of emerging markets, the currency wars, the complexities of the China-U.S. relationship, and the role of institutions like the International Monetary Fund—and offers new ideas for fixing the flawed monetary system. Readers are also given a rare look into some of the intrigue and backdoor scheming in the corridors of international finance. The Dollar Trap offers a panoramic analysis of the fragile state of global finance and makes a compelling case that, despite all its flaws, the dollar will remain the ultimate safe-haven currency.

This update of the guidelines published in 2001 sets forth the underlying framework for the Reserves Data Template and provides operational advice for its use. The updated version also includes three new appendices aimed at assisting member countries in reporting the required data.

This paper presents a rule for foreign exchange interventions (FXI), designed to preserve financial stability in floating exchange rate arrangements. The FXI rule addresses a market failure: the absence of hedging solution for tail exchange rate risk in the market (i.e. high volatility). Market impairment or overshoot of exchange rate between two equilibria could generate high volatility and threaten financial stability due to unhedged exposure to exchange rate risk in the economy. The rule uses the concept of Value at Risk (VaR) to define FXI triggers. While it provides to the market a hedge against tail risk, the rule allows the exchange rate to smoothly adjust to new equilibria. In addition, the rule is budget neutral over the medium term, encourages a prudent risk management in the market, and is more resilient to speculative attacks than other rules, such as fixed-volatility rules. The empirical methodology is backtested on Banco Mexico’s FXIs data between 2008 and 2016.
