Global roles of currencies

This paper presents a new concept – the global roles of currencies. The concept combines the domestic and international (cross-border) use of currencies and therefore captures the overall importance of different currencies in a globalised economy. The measure of a currency’s global role is based on the size and stage of development of the underlying economy, as well as the size and stage of development of its financial markets and the scope of financial instruments available in this currency. The paper applies the concept to 22 currencies of advanced and emerging economies. The results confirm the well-known ranking for the leading currencies – in particular the US dollar and the euro – but give considerably greater weight to currencies of emerging economies than the results obtained from the international debt market, which has so far been used as the basis for measuring the international role of currencies in capital markets. The paper also discusses this established measure in detail, arguing that in view of financial globalisation, an indicator based on currency shares in the international debt market alone represents a decreasing share of international financial market activity, as this market excludes government debt, other domestic debt and equities, which are in- creasingly of interest to international investors. The paper also presents an empirical application of the new global concept to examine cross-border portfolio holdings in debt and equity markets across advanced and emerging economies. It finds that the global role indicator is positively correlated with such holdings and, especially for emerging economies, fares better than the established international debt market indicator. The findings suggest a positive relationship between domestic financial development and international financial integration.

Strengthening the Governance of the International Monetary Fund: How a Dual Board Structure Could Raise the Effectiveness and Legitimacy of a Key Global Institution

After having been at the helm of the international monetary system for decades, the International Monetary Fund was sidelined in policy debates in the past few years. One reason for the IMF not having taken a more central role in addressing key global policy issues in recent years relates to its internal governance. This paper focuses specifically on the structure and functioning of the Executive Board. The paper argues that Executive Board, although uniquely placed to provide authoritative guidance to IMF member countries, exert peer pressure and give economic policy advice, is overwhelmed by its tasks and responsibilities and too large to be an effective forum for true international economic dialogue. The paper makes the point that the highly diverse tasks of the IMF require different governance structures in order to be implemented effectively. We believe that the optimal number of governing bodies for the ongoing IMF work is not one, but that it is two, duly distinguishing between multilateral matters from country-related matters. Specifically, we propose to split the tasks that are predominantly systemic in nature from those that are predominantly country-focused and technical and believe that this can be done. Two different Boards would be dealing with these issues: a Systemic Issues Board and a Country Issues Board. The paper also discusses how such a dual board structure could be implemented in practice.IMF; Governance

The external and domestic side of macroeconomic adjustment in China

This paper sheds new light on the external and domestic dimension of China’s exchange rate policy. It presents an open economy model to analyse both dimensions of macroeconomic adjustment in China under both flexible and fixed exchange rate regimes. The model-based results indicate that persistent current account surpluses in China cannot be rationalized, under general circumstances, by the occurrence of permanent technology or labour supply shocks. As a result, the understanding of the macroeconomic adjustment process in China requires to mimic the effects of potential inefficiencies, which induce the subdued response of domestic absorption to permanent income shocks causing thereby the observed positive unconditional correlation of trade balance and output. The paper argues that these inefficiencies can be potentially seen as a by-product of the fixed exchange rate regime, and can be approximated by a stochastic tax on domestic consumption or time varying transaction cost technology related to money holdings. Our results indicate that a fixed exchange regime with financial market distortions, as defined above, might induce negative effects on GDP growth in the medium-term compared to a more flexible exchange rate regime.

How insurers differ from banks: a primer on systemic regulation

This paper aims at providing a conceptual distinction between banking and insurance with regard to systemic regulation. It discusses key differences and similarities as to how both sectors interact with the financial system. Insurers interact as financial intermediaries and through financial market investments, but do not share the features of banking that give rise to particular systemic risk in that sector, such as the institutional interconnectedness through the interbank market, the maturity transformation combined with leverage, the prevalence of liquidity risk and the operation of the payment system. The paper also draws attention to three salient features in insurance that need to be taken account in systemic regulation: the quasi-absence of leverage, the fundamentally different role of capital and the ‘built-in bail-in’ of a significant part of insurance liabilities through policy-holder participation. Based on these considerations, the paper argues that if certain activities were to give rise to concerns about systemic risk in the case of insurers, regulatory responses other than capital surcharges may be more appropriate

Proximity and linkages among coalition participants: a new voting power measure applied to the International Monetary Fund

Voting power methodology offers insights to understand coalition building in collective decision making. Using cooperative game theory, Banzhaf (1965) developed an index to capture the numerical importance of voters in coalition building. This voting power index is still widely used today in applications to international politics. Yet, it assumes that voters are symmetric and focuses on particular voters only. This paper proposes a new measure of voting power which account for the numerical proximity between voters by capturing how often they appear in winning coalitions together. The index is also developed to account for the relative importance of coalitions and the relative linkages among coalition participants. We present an application to the governance structure of the International Monetary Fund, with linkages being represented by bilateral trade between voters. The results are able to explain several important features of the functioning of this particular voting body, and may be useful for other applications of international politics.

The search for Columbus’ egg - finding a new formula to determine quotas at the IMF

The International Monetary Fund (IMF) is undergoing profound changes, not only in its policies, but also in its internal governance. These changes reflect the structural developments in the global economy, and in particular the growing role of emerging economies that demand a greater say at the Fund. In addition, the Fund has recognised that it needs to strengthen the voice of developing economies in order to increase ownership of IMF programmes and policy recommendations from this very large country group. At the heart of IMF governance lies the distribution of its quota: quotas are the percent share at the IMF that are attributed to the various members. Quotas play a central role in the Fund, because they determine not only member countries’ financial contributions, but also their rights to draw on IMF financial support and their voting rights within the institution. Therefore, quotas are essentially a matter of representation, visibility, and influence of countries at the IMF. Quotas are being calculated as a function of various economic variables and also include a certain degree of judgement. This paper provides a systematic analysis of the way IMF quota have been calculated in the past and of the current challenges of reform. It shows the importance for individual variables for specific country groups and the sensitivity of changes in the formula of overall distribution. The paper provides an extensive and comprehensive overview of various technical issues involved in choosing an appropriate quota formula. It analyses the current quota system and its functioning, and shows which countries and groups are most under and over-represented. It also puts forward an analysis of the various avenues of quota-reform that are currently under discussion.

Home bias in global bond and equity markets: the role of real exchange rate volatility

This paper focuses on the role of real exchange rate volatility as a driver of portfolio home bias, and in particular as an explanation for differences in home bias across financial assets. We present a Markowitz-type portfolio selection model in which real exchange rate volatility induces a bias towards domestic financial assets as well as a stronger home bias for assets with low local currency return volatility. We find empirical support in favour of this hypothesis for a broad set of industrialised and emerging market countries. Not only is real exchange rate volatility an important factor behind bilateral portfolio home bias, but we find that a reduction of monthly real exchange rate volatility from its sample mean to zero reduces bond home bias by up to 60 percentage points, while it reduces equity home bias by only 20 percentage points.

External imbalances and the US current account: how supply-side changes affect an exchange rate adjustment

The influential work of Obstfeld and Rogoff argues that a closing-up of the US current account deficit involves a large exchange rate adjustment. However, the Obstfeld-Rogoff model works exclusively via demand-side channels and abstracts from possible supply-side changes. We extend the framework to allow for endogenous supply-side changes and show that this fundamentally alters the mechanism of the adjustment process. Allowing for such an extension attenuates quite significantly the implied exchange rate adjustment. The paper also provides some empirical evidence of variations in the supply-side structure and correlations with the exchange rate and the current account. The policy implications are that measures to foster a supply-side reaction would facilitate the external adjustment by alleviating an exclusive reliance on demand and exchange rate changes, with the latter being potentially destabilising for the global financial system.

The effective exchange rates of the euro

This paper details the methodological framework underlying the construction of the effective exchange rate (EER) indicators of the euro. This framework yields two sets of indicators - (i) one nominal and several real EER indices against a narrow reference group of euro area trading partners based on different price and cost deflators; and (ii) a nominal and a real EER index against a broad reference group of countries based on consumer prices. The narrow group consists of 12 industrial and newly industrialised euro area partner countries, while the broad group is made up of 38 trading partners including emerging market economies and economies in transition. In addition the paper computes national competitiveness indicators for the individual euro area participating countries. Finally, recent developments in the international price and cost competitiveness of the euro area as well as of euro area countries are briefly discussed on the basis of the constructed indices.
