Based on a dataset of 112 emerging economies and developing countries, this paper addresses two key questions regarding the accumulation of international reserves: first, has the accumulation of reserves effectively protected countries during the 2008-09 financial crisis? And second, what explains the pattern of reserve accumulation observed during and after the crisis? More specifically, the paper investigates the relation between international reserves and the existence of capital controls. We find that the level of reserves matters: countries with high reserves relative to short-term debt suffered less from the crisis, particularly if associated with a less open capital account. In the immediate aftermath of the crisis, countries that depleted foreign reserves during the crisis quickly rebuilt their stocks. This rapid rebuilding has, however, been followed by a deceleration in the pace of accumulation. The timing of this deceleration roughly coincides with the point when reserves reached their pre-crisis level and may be related to the fact that short-term debt accumulation has also decelerated in most countries over this period.

We explore the role of financial openness – capital account openness and gross capital inflows – and a newly constructed gravity‐based contagion index to assess the importance of these factors in the run‐up to currency crises. Using a quarterly data set of 46 advanced and emerging market economies (EMEs) during the period 1975Q1‐2011Q4, we estimate a multi‐variable probit model including in the post‐Lehman period. Our key findings are as follows. First, capital account openness is a robust indicator, reducing the probability of currency crisis for advanced economies, but less so for EMEs. Second, surges in gross (but not net) capital inflows in general increase the risk of a currency crisis, but looking at a disaggregated level, gross portfolio flows increase the risk of a currency crisis for advanced economies, whereas gross FDI inflows decrease the risk of a crisis for EMEs. Third, contagion has a very strong impact, consistent with the past literature, especially during the post‐ Lehman shock episode. Last, our model performs well out‐of‐sample, confirming that early warning models were helpful in judging relative vulnerability of countries during and since the Lehman crisis.

This paper revisits the bipolar prescription for exchange rate regime choice and asks two questions: are the poles of hard pegs and pure floats still safer than the middle? And where to draw the line between safe floats and risky intermediate regimes? Our findings, based on a sample of 50 EMEs over 1980-2011, show that macroeconomic and financial vulnerabilities are significantly greater under less flexible intermediate regimes—including hard pegs—as compared to floats. While not especially susceptible to banking or currency crises, hard pegs are significantly more prone to growth collapses, suggesting that the security of the hard end of the prescription is largely illusory. Intermediate regimes as a class are the most susceptible to crises, but “managed floats”—a subclass within such regimes—behave much more like pure floats, with significantly lower risks and fewer crises. “Managed floating,” however, is a nebulous concept; a characterization of more crisis prone regimes suggests no simple dividing line between safe floats and risky intermediate regimes.

This paper examines the effectiveness of capital outflow restrictions in a sample of 37 emerging market economies during the period 1995-2010, using a panel vector autoregression approach with interaction terms. Specifically, it examines whether a tightening of outflow restrictions helps reduce net capital outflows. We find that such tightening is effective if it is supported by strong macroeconomic fundamentals or good institutions, or if existing restrictions are already fairly comprehensive. When none of these three conditions is fulfilled, a tightening of restrictions fails to reduce net outflows as it provokes a sizeable decline in gross inflows, mainly driven by foreign investors.

In the run-up to the financial crisis the world economy was characterized by large and growing current-account imbalances. Since the onset of the crisis, China and the U.S. have rebalanced. As a share of GDP, their current-account imbalances are now less than half their pre-crisis levels. For China, the reduction in its current-account surplus post-crisis suggests a structural change. Panel regressions for a sample of almost 100 countries over the thirty-year period 1983-2013 confirm that the relationship between current-account balances and economic variables such as performance, structure, wealth and the exchange rate changed in important ways after the financial crisis.

I discuss how the unconventional monetary policy measures implemented over the past several years – quantitative and credit easing, and forward guidance – can be analysed in the context of conventional models of asset prices, with particular reference to exchange rates. I then discuss alternative approaches to interpreting the effects of such policies, and review the empirical evidence. Finally, I examine the ramifications for thinking about the impact on exchange rates and asset prices of emerging market economies. I conclude that although the implementation of unconventional monetary policy measures may introduce more volatility into global markets, in general it will support global rebalancing by encouraging the revaluation of emerging market currencies.

We study the long-run relationship between public debt and growth in a large panel of countries. Our analysis takes particular note of theoretical arguments and data considerations in modeling the debt-growth relationship as heterogeneous across countries. We investigate the issue of nonlinearities (debt thresholds) in both the cross-country and within-country dimensions, employing novel methods and diagnostics from the time-series literature adapted for use in the panel. We find some support for a nonlinear relationship between debt and long-run growth across countries, but no evidence for common debt thresholds within countries over time.

This paper examines when and why capital sometimes surges to emerging market economies (EMEs). Using data on net capital flows for 56 EMEs over 1980−2011, we find that global factors, including US interest rates and investor risk aversion act as “gatekeepers” that determine when surges of capital to EMEs will occur. Whether a particular EME receives a surge, and the magnitude of that surge, however, are largely related to domestic factors such as its external financing need, capital account openness, and exchange rate regime. Differentiating between surges driven by exceptional behavior of asset flows (repatriation of foreign assets by domestic residents) from those driven by exceptional behavior of liability flows (nonresident investments into the country), shows the latter to be relatively more sensitive to global factors and contagion.

In bilateral and multilateral surveillance, countries are often urged to consider alternative policies that would result in superior outcomes for the country itself and, perhaps serendipitously, for the world economy. While it is possible that policy makers in the country do not fully recognize the benefits of proposed alternative policies, it is also possible that the existing policies are the best that they can deliver, given their various constraints, including political. In order for the policy makers to be able and willing to implement the better policies some quid pro quo may be required—such as a favorable policy adjustment in the recipients of the spillovers; identifying such mutually beneficial trades is the essence of international policy coordination. We see four general guideposts in terms of the search for globally desirable solutions. First, all parties need to identify the nature of spillovers from their policies and be open to making adjustments to enhance net positive spillovers in exchange for commensurate benefits from others; but second, with countries transparent about the spillovers as they see them, an honest broker is likely to be needed to scrutinize the different positions, given the inherent biases at the country level. Third, given the need for policy agendas to be multilaterally consistent, special scrutiny is needed when policies exacerbate global imbalances and currency misalignments; and fourth, by the same token, special scrutiny is also needed when one country’s policies has a perceptible adverse impact on financial-stability risks elsewhere.

Taking a historical perspective of economic changes, this paper argues that muddling through crises-induced reforms characterizes well the evolutionary process of forming currency unions. The economic distortions facing the euro include structural challenges in the labor and product markets, and financial distortions. While both structural and financial distortions are costly and prevalent, they differ in fundamental ways. Financial distortions are moving at the speed of the Internet, and their welfare costs are determined more by the access to credit lines and leverage, than by the GDP of each country. In contrast, the structural distortions are moving at a slow pace relative to the financial distortions, and their effects are determined by inter-generational dynamics. These considerations suggest that the priority should be given to dealing with the financial distortions. A more perfect Eurozone is not assured without successfully muddling through painful periodic crises.

International financial linkages, particularly through global bank flows, generate important questions about the consequences for economic and financial stability, including the ability of countries to conduct autonomous monetary policy. I address the monetary autonomy issue in the context of the international policy trilemma: countries seek three typically desirable but jointly unattainable objectives: stable exchange rates, free international capital mobility, and monetary policy autonomy oriented toward and effective at achieving domestic goals. I argue that global banking entails some features that are distinct from broad issues of capital market openness captured in existing studies. In principal, if global banks with affiliates established in foreign markets can reduce frictions in international capital flows then the macroeconomic policy trilemma could bind tighter and interest rates will exhibit more co-movement across countries. However, if the information content and stickiness of the claims and services provided are enhanced relative to a benchmark alternative, then global banks can weaken the trilemma rather than enhance it. The result is a prediction of heterogeneous effects on monetary autonomy, tied to the business models of the global banks and whether countries are investment or funding locations for those banks. Empirical tests of the trilemma support this view that global bank effects are heterogeneous, and also that the primary drivers of monetary autonomy are exchange rate regimes.

We analyse global and euro area imbalances by focusing on China and Germany as large surplus and creditor countries. In the 2000s, domestic reforms in both countries expanded the effective labour force, restrained wages, shifted income towards profits and increased corporate saving. As a result, both economies’ current account surpluses widened before the global financial crisis, and that of Germany has proven more persistent as domestic investment has remained subdued.

In contrast to earlier recessions, the monetary regimes of many small economies have not changed in the aftermath of the global financial crisis. This is due in part to the fact that many small economies continue to use hard exchange rate fixes, a reasonably durable regime. However, most of the new stability is due to countries that float with an inflation target. Though a few have left to join the Eurozone, no country has yet abandoned an inflation targeting regime under duress. Inflation targeting now represents a serious alternative to a hard exchange rate fix for small economies seeking monetary stability. Are there important differences between the economic outcomes of the two stable regimes? I examine a panel of annual data from more than 170 countries from 2007 through 2012 and find that the macroeconomic and financial consequences of regime‐choice are surprisingly small. Consistent with the literature, business cycles, capital flows, and other phenomena for hard fixers have been similar to those for inflation targeters during the Global Financial Crisis and its aftermath.

  • Much has been done since 2010 to reduce macroeconomic imbalances in the Euro Area periphery and to bolster economic and financial integration at the EU level
  • Stronger exports may now be stabilizing output after two years of contraction, but headwinds remain with fiscal adjustment continuing and bank lending constrained
  • Market sentiment, underpinned by OMT, has improved with better economic news
  • Challenges remain, however, including the need to restore full bond market access for Portugal as well as Ireland and agree further financing and relief for Greece
  • Italy remains at risk over the longer term, with a return to durable growth requiring deeper structural reforms that political divisions are likely to impede
  • Progress mutualizing sovereign and bank liabilities looks likely to remain limited, leaving Euro Area members vulnerable to renewed weakness in market sentiment
