This article provides a comprehensive history of anchor or reference currencies, exchange rate arrangements, and a new measure of foreign exchange restrictions for 194 countries and territories over 1946–2016. We find that the often cited post–Bretton Woods transition from fixed to flexible arrangements is overstated; regimes with limited flexibility remain in the majority. Even if central bankers’ communications jargon has evolved considerably in recent decades, it is apparent that many still place a large implicit weight on the exchange rate. The U.S. dollar scores as the world’s dominant anchor currency by a very large margin. By some metrics, its use is far wider today than 70 years ago. In contrast, the global role of the euro appears to have stalled. We argue that in addition to the usual safe assets story, the record accumulation of reserves since 2002 may also have to do with many countries’ desire to stabilize exchange rates in an environment of markedly reduced exchange rate restrictions or, more broadly, capital controls: an important amendment to the conventional portrayal of the macroeconomic trilemma.

This paper examines the claim that exchange rate regimes are of little salience in the transmission of global financial conditions to domestic financial and macroeconomic conditions by focusing on a sample of about forty emerging market countries over 1986 to 2013. Our findings show that exchange rate regimes do matter. The transmission of global financial shocks to domestic credit and house price growth, as well as to banking sector leverage and domestic output, is magnified under fixed exchange rate regimes relative to more flexible (though not necessarily fully flexible) exchange rate regimes.

We review the findings of the literature on the benefits of international financial flows and find that they are quantitatively elusive. We then present evidence on the existence of a global cycle in gross cross-border flows, asset prices and leverage and discuss its impact on monetary policy autonomy across different exchange rate regimes. We focus in particular on the effect of US monetary policy shocks on the UK's financial conditions.

This paper studies the synchronization of financial cycles across 17 advanced economies over the past 150 years. The comovement in credit, house prices, and equity prices has reached historical highs in the past three decades. While comovement of credit and house prices increased in line with growing real sector integration, comovement of equity prices has increased above and beyond growing real sector integration. The sharp increase in the comovement of global equity markets is particularly notable. We demonstrate that fluctuations in risk premiums, and not risk-free rates and dividends, account for a large part of the observed equity price synchronization after 1990. We also show that US monetary policy has come to play an important role as a source of fluctuations in risk appetite across global equity markets. These fluctuations are transmitted across both fixed and floating exchange rate regimes, but the effects are more muted in floating rate regimes.

This book presents an economic survey of international capital mobility from the late nineteenth century to the present. The authors examine the theory and empirical evidence surrounding the fall and rise of integration in the world market. A discussion of institutional developments focuses on capital controls and the pursuit of macroeconomic policy objectives in shifting monetary regimes. The Great Depression emerges as the key turning point in recent history of international capital markets, and offers important insights for contemporary policy debates. Its principal legacy is that the return to a world of global capital is marked by great unevenness in outcomes regarding both risks and rewards of capital market integration. More than in the past, foreign investment flows largely from rich countries to other rich countries. Yet most financial crises afflict developing countries, with costs for everyone.

We develop a novel system of reclassifying historical exchange rate regimes. One key difference between our study and previous classifications is that we employ monthly data on market-determined parallel exchange rates going back to 1946 for 153 countries. Our approach differs from the IMF official classification (which we show to be only a little better than random); it also differs radically from all previous attempts at historical reclassification. Our classification points to a rethinking of economic performance under alternative exchange rate regimes. Indeed, the breakup of Bretton Woods had less impact on exchange rate regimes than is popularly believed.

This article aims to empirically examine the validity of two related hypotheses in the context of emerging markets. The first suggests that the flexibility and adjustment of the real exchange rate promote external stability, while the second posits that a flexible exchange rate facilitates such adjustment. To achieve this, two empirical methodologies are employed: first, an event analysis is used to identify current account adjustment episodes during the 1980–2021 period. Then, an econometric technique is applied to estimate the impact of exchange rate regimes on the current account imbalances: the System Generalised Method of Moments. The study concludes that countries with more flexible exchange rate regimes tend to experience smaller and less costly external imbalances. Moreover, the econometric analysis indicates that current account adjustments occur more rapidly in these countries compared to those with fixed or intermediate exchange rate regimes. These results suggest emerging markets should consider adopting more flexible exchange rate regimes to enhance external stability and reduce the economic costs of persistent imbalances. Policymakers could also enhance long-term economic stability and reduce the impact of external shocks by adopting counter-cyclical fiscal policies and creating sovereign wealth funds.

This study exploits a new long-run data set of daily bid and offered exchange rates in spot and forward markets from 1919 to the present to analyze carry returns in fixed and floating currency regimes. We first find that outsized carry returns occur exclusively in the floating regime, being zero in the fixed regime. Second, we show that fixed-to-floating regime shifts are associated with negative returns to a carry strategy implemented only on floating currencies, robust to the inclusion of volatility risks. These shifts are typically characterized by global flight-to-safety events that represent bad times for carry traders.

The traditional approach to monetary policy, which relied on one instrument to achieve a single goal, has proven ineffective during recent periods of global instability. In response to the challenges that this traditional framework could not address, non-standard monetary policy instruments have emerged. While they have somewhat alleviated problems, they cannot be considered a solution, as their long-term application could lead to the emergence of several other imbalances. Therefore, this paper explores a new framework for monetary policy based on two nominal anchors. The analysis focuses on two monetary regimes. The first is based on a modification of the inflation targeting regime, which would additionally include a nominal anchor in the form of an exchange rate. This is not a completely new regime, as some countries have already used an implicit exchange rate target alongside an inflation target. The second regime under consideration is entirely new and would be based on a monetary target and an interest rate target.

Domestic factors, such as credit and preference shocks, can explain the negative correlation between house prices and the current account in the U.S. and several other countries before the recent crisis. These shocks, however, cannot account for the fall of world real interest rates observed in the data. Expansionary monetary policy shocks in the U.S., coupled with exchange rate pegs to the dollar in emerging economies, are crucial to understanding the evolution of the real interest rate. Yet, monetary policy factors play virtually no role for house prices and the current account.
