Financial dollarization and systemic risks: New empirical evidence

This paper explores the persistence of financial dollarization in a group of 79 economies with different levels of development. Our main hypothesis is that a high level of domestic debt combined with default risk explains this persistence, even after a decline in inflation rates. Using the generalized method of moments (GMM) in a panel data analysis, our results show that inflation risks caused by increasing probability of default account for financial dollarization more than inflation rate itself. After the decrease in inflation rates, the foreign currency-denominated deposits remain large because of the high debt-to-GDP ratios, particularly in speculative-grade economies. High public indebtedness leads to expectations of default. Dollarization is a rational response to the future inflation associated with investors' expectations of default observed in highly indebted economies.     

Financial dollarization in Russia: causes and consequences

We review some aspects of financial dollarization in Russia, applying the main relevant theories to analyse the dynamics of several dollarization indicators. An econometric model of the short-run dynamics of deposit and loan dollarization is estimated for the last decade. We find that ruble appreciation was the main driver of the de-dollarization that occurred then and of the later episode of renewed dollarization. We estimate the overall (and sectoral) currency mismatches of the Russian economy. Evidence is presented for the significant currency risk vulnerability of the non-banking private sector.     

Financial dollarization: Short-run determinants in transition economies

This paper examines the determinants of financial dollarization in transition economies from a short-run perspective. Using aggregate monthly data of deposit and loan dollarization we study the drivers of short-term fluctuations in dollarization and test their importance at different levels of dollarization. The results provide evidence that (a) the positive (negative) short-run effects of depreciation (monetary expansion) on deposit dollarization are exacerbated in high-dollarization countries; (b) short-run loan dollarization is mainly driven by banks matching of domestic loans and deposits, currency matching of assets and liabilities, international financial integration, and institutional quality; and (c) both types of short-run dollarization are affected by interest rate differentials and deviations from desired dollarization.     

Dollarization of bank deposits: Causes and consequences

This paper assesses the benefits and risks associated with dollarization of bank deposits. We provide novel empirical evidence on the determinants of deposit dollarization, its role in promoting financial development, and on whether dollarization is associated with financial instability. We find that: (a) the credibility of macroeconomic policy and the quality of institutions are both key determinants of cross-country variations in dollarization; (b) dollarization is likely to promote financial deepening only in a high inflation environment; and (c) financial instability is likely higher in dollarized economies. The implications of these findings for financial sector and monetary policies are briefly discussed.     

The Impact of Deposit Dollarization on Financial Deepening

Banks in highly dollarized economies face risks that significantly affect their ability to perform their financial intermediation role. In these economies, dollarization plays a dual role: on the one hand, it provides a hedging instrument protecting the value of savings; on the other hand, it generates a currency mismatch on banks' balance sheets and increases default risk. Through these effects deposit dollarization can affect credit extension. This paper investigates the role of deposit dollarization on the financial depth of forty-four emerging market economies. Findings suggest that deposit dollarization has a consistent and negative impact on financial deepening, except in high-inflation economies.     

Financial dollarization: The role of foreign-owned banks and interest rates

Why in many economies households and firms borrow and make deposits in foreign currency? Expanding on the existing literature, our framework addresses this question allowing for interest rate differentials and access to foreign funds to play a role in explaining this process of asset substitution or financial dollarization. Using a newly compiled data set on transition economies and employing a standard panel as well as a panel-VAR methodology we find that increasing access to foreign funds leads to higher credit dollarization, while it decreases deposit dollarization. Interest rate differentials matter for the dollarization of both loans and deposits.     

Does Inflation Targeting Help Reduce Financial Dollarization?

We examine whether adopting an inflation‐targeting regime helps reduce financial dollarization as predicted by Ize and Levy Yeyati's ( 2003 ) portfolio model. To address the self‐selection problem of policy adoption, we apply a variety of propensity score matching methods to a large sample of 106 developing countries for the years 1985–2004. We find strong evidence that inflation targeting has large and significant treatment effects on lowering both actual financial dollarization and the model implied minimum variance portfolio dollarization. Our results are robust to alternative samples and model specifications and also to control for additional factors in postmatching regressions.     

DOLLARIZATION FOR ARGENTINA

In January 1999, President Carlos Menem suggested replacing the Argentine peso with the U.S. dollar. President Menem's announcement has sparked a debate throughout Latin America and Eastern Europe about what has been termed "dollarization." That debate prompted U.S. Treasury Secretary Robert Rubin to deliver a major policy speech on alternative exchange-rate regimes on April 21, 1999 and the U.S. Senate Banking Committee to hold dollarization hearings the following day featuring Fed Chairman Alan Greenspan and Deputy Secretary of the Treasury Lawrence Summers.
This article presents a case for officially dollarizing Argentina. Dollarization is not new. Unofficial dollarization is widespread in emerging market countries; in fact, as much as 70% of the stock of U.S. dollars now circulates abroad. Twenty-eight countries and dependent territories are officially dollarized. Although official dollarization would result in Argentina losing seigniorage of about 0.22 percent of GDP, the author estimates that this cost would be more than offset by a reduction in interest rates that would increase Argentina's trend rate of GDP growth by about two percent.
After debunking the most common criticisms of dollarization, the article closes by offering recommendations about the specific form of dollarization and presenting a detailed dollarization statute for Argentina. The author proposes a competitive currency regime for Argentina, one in which all foreign money would be legal tender.     

Dollarization,Seigniorage, and Prices: The Case of North Korea

This study employs a general equilibrium monetary search model to examine the effects of the recent dollarization in North Korea on seigniorage and prices. Maximum seigniorage is generated at a high rate of money growth when dollarization is mild. However, under a high degree of dollarization seigniorage declines sharply when the money growth rate is high. Accordingly, seigniorage can be increased by de-dollarizing the economy through lowering the money growth rate. This finding implies that the post-2013 price stabilization may be a result of the restriction on printing of money with the aim of increasing seigniorage. This finding also recognizes that the North Korean authorities have little room for maneuver on monetary policy under the conditions of widespread dollarization.     

Systemic Risk, Dollarization, and Interest Rates in Emerging Markets: A Panel-Based Approach

This study investigates the impact of systemic risks and financialdollarization on real interest rates in emerging economies.Higher systemic risks induce both higher real interest ratesand increased dollarization. Using appropriate instruments forthe dollarization ratio, the study overcomes the simultaneousequation problem and correctly estimates a negative coefficientfor the dollarization ratio in the interest rate equation. Itconfirms the theoretical prediction that a strategy of "dedollarizing"the economy will raise the equilibrium domestic real interestrate if the strategy fails to address fundamental macroeconomicrisks. Even so, it also finds that this effect is small, aftercontrolling for the risks of dilution and default. The resultsbring to light the systemic-risk reasons for high interest ratesin emerging economies—and contribute to evaluating thedifficulties of dedollarization policies.     

Currency-Induced Credit Risk in a Dollarized Economy

We analyze the effects of exchange rate fluctuations on corporate credit default in a dollarized economy. The application, before an exogenous exchange rate shock, of a new regulation concerning currency-induced credit risk (CICR) in the Peruvian banking system created natural conditions for a comparison between exposed and unexposed corporate borrowers. We use firm-level data to find that CICR and debt dollarization have opposite effects on credit risk. While CICR increases default, debt dollarization reduces it. Our results suggest that banks transfer exchange risk as a hedging mechanism by lending to such borrowers in dollars only.     

What drives credit dollarization in transition economies?

This paper provides an in-depth analysis of the use of foreign currencies in the lending activities of banks in transition economies. The impact of bank and firm variables on credit dollarization is studied in an optimal portfolio allocation model and estimated using new aggregate data for 21 transition economies for the period 1990–2003. Empirical results provide evidence that credit dollarization is the combined outcome of domestic deposit dollarization and banks’ desire for currency-matched portfolios beyond regulatory requirements. The effects of international financial factors and natural hedges are less robust across alternative specifications. The paper further discusses the role of regulations in affecting the impact of these factors on credit dollarization and calls for more developed domestic forward foreign exchange markets.     

Dollarization and currency exchange

We use a dual currency money search model to study dollarization. Agents hold portfolios consisting of two currencies, one of which is risky. We use numerical methods to solve for the steady-state distributions of currency portfolios, transaction patterns, and value functions. As risk increases, agents increasingly use the safe currency as a medium of exchange—dollarization occurs. Furthermore, the safe currency trades for multiple units of the risky currency. This type of currency exchange, and the corresponding nominal exchange rate, are often observed in black market or unofficial currency exchange markets in developing countries. Due to decentralized trading, a distribution of exchange rates arises, whose mean and variance change in predictable ways when currency risk increases.     

The relationship between investment and large exchange rate depreciations in dollarized economies

We use a simple financial friction in an economy with high degree of liability dollarization - and currency mismatch - to show that the negative balance-sheet effect of an exchange rate depreciation may be observable only if the magnitude of the depreciation is large enough. This result justifies the difficulty to find strong empirical evidence for balance-sheet effects and suggests the convenience of including a “large depreciation” term in empirical analyses. We review some of the related empirical literature and provide some new evidence of this large depreciation effect.     

The hysteresis of currency substitution: Currency risk vs. network externalities

It is widely documented that currency substitution (using foreign money in transactions) increases in periods of high inflation but does not decline once inflation is reduced. The paper uses survey data from Bulgaria, which experienced this phenomenon, to investigate the origins of this ratchet effect. We find that expected devaluation of the domestic currency, while relatively high, does not play a major role in sustaining the dollarization of transactions. Conversely, preferences for the use of foreign money are strongly influenced by people's perception that foreign money is already widely used in the economy.     

Dollarization does promote trade

This study re-evaluates the treatment effect of dollarization on trade while explicitly controlling for self-selection of policy adoption. Employing a variety of propensity score matching methods, we show that dollarization not only increases bilateral US trade with dollarized countries, but promotes a dollarizer’s bilateral trade with other dollar-zone countries as well.     

Dollarization in Emerging Markets: Evidence from Georgia

This paper studies dollarization using the implications of three versions of a money-in-utility function model. These versions accentuate the roles of the exchange rate, the interest rates on foreign and domestic currencies time deposits, and domestic and foreign inflation. Monthly Georgian data for the period 1996-2007 are employed in the analysis. Findings indicate that the U.S. dollar is a strong substitute for the domestic currency and has a significant share in domestic liquidity services. The historical dollarization is well explained by the exchange rate model.     

Dollars, Debt, and International Financial Institutions: Dedollarizing Multilateral Lending

Financial dollarization is increasingly seen as a concern becauseof its tendency to contribute to financial crises and outputvolatility. As a result the debate on financial dollarizationhas shifted in favor of a more proactive stance on dedollarization.While often neglected, lending from international financialinstitutions is an important source of financial dollarizationin emerging economies and must be considered in any dedollarizationstrategy. This article revisits old and new arguments in favorof international financial institution lending in the localcurrency and argues that any such initiative should rely, atleast initially, on demand from residents seeking stable returnsin units of the local consumption basket but who are reluctantto take on sovereign risk. Superior enforcement capacity enablesinternational financial institutions to intermediate these savings,currently invested in dollarized foreign assets, back into thelocal economy. The international financial institutions canoffer investment-grade local currency bonds and use the proceedsto dedollarize their own lending to noninvestment-grade countries,thereby reducing financial dollarization and fostering the developmentof local currency markets.     

Conditional versus unconditional persistence of RNOA components: implications for valuation

Financial analysis often involves decomposing variables into components, emphasizing the structured hierarchy among ratios. We distinguish between unconditional persistence (a variable’s autocorrelation coefficient), and conditional persistence (the power of a variable’s persistence to explain the persistence of a variable higher in the hierarchy). We argue that a variable’s conditional persistence determines the magnitude of its market reaction, allowing us to predict the relative magnitude of the market reaction to a ratio depending on its hierarchal level in the analysis. We examine the market reaction to the DuPont ratios and find that, while the unconditional persistence of asset turnover (ATO) is larger than that of operating profit margin (OPM), the conditional persistence of OPM is larger than that of ATO. Thus, we predict and find that the market’s reaction to OPM is stronger than that to ATO. We further decompose OPM and ATO into their second-order components and show that the market reaction depends on a component’s conditional persistence.     

How persistent is private equity performance? Evidence from deal-level data

The persistence of returns is a critical issue for investors in their choice of private equity managers. In this paper, we analyse buyout performance persistence in new ways, using a unique database containing cash flow data on 13,523 portfolio company investments by 865 buyout funds. We focus on unique realized deals and find that persistence of fund managers has substantially declined as the private equity sector has matured and become more competitive. Private equity has, therefore, largely conformed to the pattern found in most other asset classes in which past performance is a poor predictor of the future.
