Monetary unions, external shocks and economic performance: A Latin American perspective

During the last few years there has been a renewed analysis in currency unions as a form of monetary arrangement. This new interest has been largely triggered by the Euro experience. Scholars and policy makers have asked about the optimal number of currencies in the world economy. They have analyzed whether different countries satisfy the traditional “optimal currency area” criteria. These include, among other: (a) the synchronization of the business cycle; (b) the degree of factor mobility; and (c) the extent of trade and financial integration. In this paper I analyze the desirability of a monetary union from a Latin American perspective. First, I review the existing literature on the subject. Second, I use a large data set to analyze the evidence on economic performance in currency union countries. I investigate these countries’ performance on four dimensions: (a) whether countries without a national currency have a lower occurrence of “sudden stop” episodes; (b) whether they have a lower occurrence of “current account reversal” episodes; (c) what is their ability to absorb international terms of trade shocks; and (d) what is their ability to absorb “sudden stops” and “current account reversals” shocks. I find that belonging to a currency union has not lower the probability of facing a sudden stop or a current account reversal. I also find that external shocks have been amplified in currency union countries. The degree of amplification is particularly large when compared to flexible exchange rate countries.     

Intraregional Cross-holding of Reserve Currencies： A Proposal for Asia to Deal with the Global Reserve Risks

Economists have put forward various proposals to deal with the growing risks of the global reserve currency system. In this paper we recommend that Asian economies hold each other＇s currencies as part of their foreign reserves. Different from crisis-fighting currency swap arrangements or crisis-rescuing fund mechanisms, this mechanism means that reserves wouM be held, with a regular arrangement in place and on an ongoing basis. We propose that the global reserve system shouM be pushed in the direction of diversification, which could be a transitional step toward a new single reserve system. This mechanism would not necessitate any currency being a globally accepted reserve currency but would mean that every currency carried some weight in the reserve system. Establishment of such a system would require significant development of regional bond markets and facilitation of macroeconomic surveillance among the economies.     

Comparing Exchange Market Pressure across Five African Countries

This paper compares the credibility of exchange rate arrangements for the five African countries which are members of the Community of Portuguese Speaking Countries and will be referred to as Afro-Luso. Our working hypothesis is that credibility necessarily implies low mean exchange market pressure (EMP), low EMP conditional volatility and low-severity EMP crises under financial-market integration. In addition, economic fundamentals must account for EMP dynamics. We also seek evidence of a risk–return relationship for mean EMP and of “bad news” (negative shocks) having a greater impact on EMP volatility than “good news” (positive shocks). Using our econometric models, we are able to rank Afro-Luso countries’ conditional volatility in ordinal terms. Our main conclusion is that countries with currency pegs, such as Guinea-Bissau (GB) and Cape Verde (CV), clearly have lower volatility when compared to those with managed floats and are therefore more credible. Moreover, EMP crises episodes under pegs are much less severe. We find that economic fundamentals correctly account for mean EMP in all countries and that the risk–return relationship is much more favourable for investors under currency pegs, as the increase in volatility is lower for the same rate of return. The exception to this finding is Mozambique (MOZ), which apparently has a risk–return profile akin to that enjoyed by countries with pegs. A plausible reason is that MOZ has the only managed float in our sample implementing monetary and exchange rate policy within the confines of an IMF framework, which establishes floors for international reserves and ceilings for the central bank’s net domestic assets. This intuition needs to be tested, however. EMP conditional volatility, meanwhile, is generally driven by changes in domestic credit (lowers it) and foreign reserve changes (raises it). The first effect is more pronounced under currency pegs, but also under MOZ’s managed float. “Bad news” increases volatility more that “good news” only in the case of CV’s currency peg, which we take to be another sign of its credibility. A few striking cross-country comparisons also emerge in our analysis. Among countries with managed floats, Angola (ANG) has the most severe EMP crises, MOZ the least severe and São Tomé &; Príncipe (STP) lies between the two extremes but closer to MOZ.

Renminbi Internationalization in the New Normal: Progress,Determinants and Policy Discussions

In the present paper we explore the internationalization of the renminbi with reference to the experiences of other monetary powers, and discuss its determinants, prospects and implications for China's development in the “new normal.” Specifically, after summarizing the major progress made thus far, we conduct a regression analysis, showing that economic size and financial conditions are significant determinants of the international currency status, while inertia and other unobserved factors also play important roles. These empirical findings enable us to undertake a scenario analysis focusing on the renminbi's potential to become a global reserve currency. Based on this quantitative research, we then revisit China's policy initiatives designed to promote its currency overseas. In our view, the internationalization of the renminbi, along with financial deepening and liberalization, should be regarded as a means to achieve China's goal of reaching a more sustainable and balanced model of development.     

Enhanced Special Drawing Rights: How China Could Contribute to a Reformed International Monetary Architecture

Since the end of the Bretton Woods era, the world has operated on a de facto system of free‐floating exchange rates, with the US dollar as the dominant international currency. The system, characterized by large pro‐cyclical capital flows and chronic imbalances, is inherently unstable, and has contributed to repeated crises, recessions and geopolitical tensions. One potentially “least‐difficult” line of reform would be to allow the evolution of a multi‐currency system, underpinned by an expanded role for Special Drawing Rights (SDRs). Attempts to promote wider use of the SDR have foundered on the liquidity premium. However, for Chinese corporations and institutions, at present restricted in their capital account activities, the SDR liquidity premium would appear less daunting. The Chinese authorities could provide policy encouragement for the use of SDRs by their institutions. This initiative, supported by China's Special Administrative Region Hong Kong, would kick‐start an international SDR ecosystem, and encourage even broader use of SDRs, to the benefit of international monetary stability.     

The Yen,the US dollar,and the trade weighted basket of currencies: Does the choice of anchor currencies matter in identifying incidences of speculative attacks?

Early constructions of a single crisis index known as the exchange market pressure (EMP) index have largely been based on the fluctuations of the real or nominal exchange rate of a currency against the US dollar—the most commonly accepted anchor currency in the global market. Hardly any studies have however tested the sensitivity of this crisis index to the choice of different “anchor” currencies. To address this pertinent issue, our study considers the EMP indices of the Indonesian rupiah, Malaysian ringgit and Thailand baht constructed by adopting three different exchange rates—the real effective rate, the local currency against the US dollar, and the local currency against the Japanese yen for the period of 1985–2003. The test results indicate that the reported incidences of speculative attacks are highly sensitive to the choice of anchor currencies.     

In the Eyes of the State: Negotiating a “Rights-Based Approach” to Forest Conservation in Thailand

Recent debates about governance, poverty and environmental sustainability have emphasized a “rights-based” approach, in which equitable development is strongly associated with individual and communal rights. This paper reviews this approach and explores its practical application to Thailand's “Community Forestry Bill,” which seeks to establish communal rights of access and conservation in forest reserve areas. The paper examines conflicts concerning watershed forests and mangroves in Thailand, and argues that efforts to support rural livelihoods through community rights have been undermined by a state that has frequently supported commercial interests or opposed decentralization to minority groups. The paper documents how civil society organizations may negotiate rights within the wider public spheres in which rules, rights, and “community” are established, and defended.

Nominal debt and inflation stabilization

The “fiscal theory of currency crises” ( Daniel 2001 ; Corsetti and Ma?kowiak 2005, 2006 ) claims that with long‐term nominal debt, a government can delay the timing of an inevitable currency crisis that results from a fiscal shock. The present paper shows that, in contrast, long‐term nominal debt might have destabilizing effects when a government introduces an inflation stabilization policy. It is shown that a stabilization policy that is successful in the absence of long‐term nominal debt can cause a crisis when long‐term nominal debt exists. The model implies that a government with a large stock of long‐term nominal debt must overcome a high fiscal hurdle for a successful stabilization policy. This difficulty is avoidable if long‐term debt is indexed to inflation.     

Backward participation in global value chains and exchange rate driven adjustments of Swiss exports

This paper examines the effect of exchange rate movements on export volume, export revenues and propensity to export taking into account the extent of foreign value added content of exports (“backward integration”) in global value chains (GVCs). Using both product-level and firm-level panel data, our results suggest that Swiss exports (intensive margin) and the export probability (extensive margin) are negatively affected by a currency appreciation. However, this adverse effect is mitigated in sectors and firms that are more integrated in GVCs, which could be explained by the “natural hedging” of exchange rate movements. Our findings are robust to the use of different measures of natural hedging and GVC integration and also hold across various specifications and estimation methods that control for sample selection, firm heterogeneity, heteroskedastic errors and persistence in export behavior. The dynamic specifications also reveal that export hysteresis driven by a currency appreciation is a concern particularly for firms that are not established in export markets.     

Are Central Bankers Currency Manipulators?

The term “currency manipulator” has been used by the United States to describe the monetary practices of nations such as China and Japan and by Germany to describe U.S. monetary policy. This charge transcends monetary regimes and includes both traditional monetary policy and that in the service of industrial or developmental strategies that center on export led growth. While the latter clearly has a negative effect on employment and economic growth in the rest of the world, the increased international mobility of capital, combined with the wide-spread use of flexible exchange rates, has led to the same external effects from the normal conduct of monetary policy. Acknowledging and dealing with these negative external effects will lead to improved and less tension-filled international economic relations than calling nations “currency manipulators.”.     

Bank Indonesia and The Recent Crisis

This paper is a personal note describing the crisis as it unfolded while the writer was a key player in Indonesia's macroeconomic management. The crisis is seen as multi-faceted. It originated externally from a shock in the currency market that triggered a downward spiral from currency depreciation to fully-fledged crisis. The currency shock that hit the rupiah in July 1997 exposed in sequence the flaws embedded in the banking sector, the economic system, the social and the political system, flaws that had been obscured by long years of good economic performance. Through a complicated process of contagion and feedback effects—market disturbances, policy responses and market reactions—Indonesia deteriorated from a relatively well managed economy to the “worst case” among the Asian crisis economies. The paper discusses this process, the IMF's role, the bank closure issue, the currency board controversy and the author's dismissal as Governor of Bank Indonesia.     

David Hume on Banking and Hoarding

David Hume opposes banks and favors hoarding. The only bank he reluctantly approves of is a public, 100% reserve bank. Other banks increase money supply and prices, hindering exports and economic growth. For Hume, a 100% reserve public bank would lead to “the destruction of paper‐credit” ([1752] 1985, p. 285), fostering economic growth instead by preventing inflation. Additionally, a 100% reserve bank hoards a large quantity of gold and silver, which is available in case of national emergency.     

Interest-Rate Spread and Public-Debt Dynamics in a Two-Country Monetary-Union Portfolio Model

Tracking, monitoring and steering the evolution of public debt over time will be a major policy challenge for almost all governments in the advanced countries in the years to come, in particular for those belonging to the European Monetary Union. In this paper I study public debt dynamics in a two-country monetary union where a representative, risk-averse wealth-owner optimizes his/her portfolio of sovereign bonds issued in the common currency. I obtain two main results with respect to the standard country-by-country approach. First, the interest-rate spread between the two countries is endogenized as the higher-debt country pays a risk premium which is proportional to the level of its own debt with respect to the debt of the other. Second, its debt dynamic path becomes nonlinear and dependent on the evolution of the other country’s debt. The most important policy implication is that “dynamic interdependence” is not fully considered in the implementation of EMU fiscal rules, but it may may jeopardize their goal of convergence and stability of debt stocks.     

The economics of convergence: Towards monetary union in Europe

The Economics of Convergence: Towards Monetary Union in Europe. —In this paper, the literature on monetary integration has been surveyed in order to discover the economic rationale of the Maastricht convergence requirements. The traditional theory of optimum currency areas is silent on the need for Maastricht-type convergence requirements. Similarly, the “new” view of monetary integration using credibility concepts cannot easily be used to justify these convergence requirements. It is also argued that the dynamics of the convergence requirements will almost certainly lead to a “Great Divide” of the European Union. The paper concludes that less emphasis should be put on prior convergence conditions and more on strengthening the functioning of the future monetary institutions in the Union.     

Optimal currency shares in international reserves: The impact of the euro and the prospects for the dollar

Foreign exchange reserve accumulation has risen dramatically in recent years. The introduction of the euro, greater liquidity in other major currencies, and the rising current account deficits and external debt of the United States have increased the pressure on central banks to diversify away from the US dollar. A major portfolio shift would significantly affect exchange rates and the status of the dollar as the dominant international currency. We develop a dynamic mean-variance optimization framework with portfolio rebalancing costs to estimate optimal portfolio weights among the main international currencies. Making various assumptions on expected currency returns and the variance–covariance structure, we assess how the euro has changed this allocation. We then perform simulations for the optimal currency allocations of four large emerging market countries (Brazil, Russia, India and China), adding constraints that reflect a central bank's desire to hold a sizable portion of its portfolio in the currencies of its peg, its foreign debt and its international trade. Our main results are: (i) The optimizer can match the large share of the US dollar in reserves, when the dollar is the reference (risk-free) currency. (ii) The optimum portfolios show a much lower weight for the euro than is observed. This suggests that the euro may already enjoy an enhanced role as an international reserve currency (“punching above its weight”). (iii) Growth in issuance of euro-denominated securities, a rise in euro zone trade with key emerging markets, and increased use of the euro as a currency peg, would all work towards raising the optimal euro shares, with the last factor being quantitatively the most important.

The internationalization of the RMB: where does the RMB currently stand in the process of internationalization

Renminbi (RMB) internationalisation has been a topic for lively discussion since China accelerated its promotion of the RMB's status as a leading international currency in 2009. China has undertaken some concrete steps to push forward RMB internationalisation such as the Pilot Scheme of Cross‐Border Trade Settlement in the RMB, RMB Qualified Foreign Institutional Investor, Dim Sum bonds, and bilateral currency swap agreements. Where the RMB stands in the process of becoming an international currency is assessed by reviewing the progress China has made and analysing the challenges China faces in internationalising its currency. Based on this assessment, a roadmap for internationalising the RMB is drawn from two perspectives: the functions of the RMB as an international currency and the scope of RMB use in the global financial system. A possible roadmap for RMB internationalisation is to begin from RMB settlement in cross‐border trade, followed by regionalisation of the RMB, and finally globalisation. With respect to achieving the functions of an international currency, the RMB should first become a settlement currency, then a denomination currency, and lastly, a reserve currency.

Mercantilism and China's hunger for international reserves

This paper is motivated by the popular view that the surge in China's foreign exchange reserves is due to a distortionary exchange rate policy aimed at keeping the real exchange rate undervalued to support export-led growth. It undertakes an in-depth empirical investigation to quantify how much “mercantilist” and “precautionary” motives have contributed to the reserve build-up in China during 1998Q4-2011Q4. A substantial problem is that theory is consistent with employing two vastly differing approaches to defining and estimating the role of mercantilist reserve accumulation. A priori, either method could generate misleading results. The study shows, however, that the distinction between the two approaches is immaterial in China's case. The results suggest that mercantilism accounts for less than 10% of reserve accumulation. Precautionary motives and other factors seem to be the dominant determinants of the surge in China's international reserves.
