Endogenous inflows of speculative capital and the optimal currency appreciation path

Abstract This paper examines the optimal appreciation path of an undervalued currency in the presence of speculative capital inflows that are endogenously affected by the appreciation path. A central bank decides its appreciation policy based on three costs: (i) misalignment costs associated with the gap between the actual and long‐run equilibrium exchange rates, (ii) short‐term adjustment costs due to resource reallocation, and (iii) capital losses due to speculative capital inflows. Our model finds (1) when speculators face no liquidity shocks, the central bank tends to appreciate the currency quickly to discourage speculative capital; (2) when speculators face liquidity shocks, the central bank optimally pre‐commits to a slower appreciation path, and the appreciation takes the longest time when the probability of liquidity shocks takes intermediate values; (3) the central bank tends to appreciate the currency more quickly when it conducts discretionary policy.     

A Model of Crises in Emerging Markets

This paper presents a perfect foresight model of speculative attacks on emerging markets. Credit constrained governments are assumed to have two objectives: to accumulate liquid assets in order to self-insure against shocks to national consumption and to insure poorly regulated domestic financial markets. This policy regime generates endogenous fiscal deficits defined to include the growth of contingent liabilities. The model sets out a sequence of yield differentials consistent with capital inflows followed by anticipated speculative attacks. The model suggests that a common shock generated capital inflows to emerging markets in Asia and Latin America after 1989.     

Macroeconomic adjustment with managed exchange rates and capital controls: Some lessons from China

This paper examines the performance of capital controls and exchange-rate management when the economy finds itself in dark corners. These are times when the real sector experiences a sequence of prolonged negative shocks from world demand, while the central bank faces low world interest rates on its foreign-exchange reserve holdings. We examine two regimes, one of a fixed exchange rate with strong capital controls and another with a more open capital account with a managed exchange rate. We show how this model replicates recent experiences of China as it moved from a relatively fixed exchange rate regime with strong capital controls to a more flexible exchange rate regime with a more open capital account. Our results show that capital-account liberalization should be accompanied by domestic price liberalization to avoid large losses in foreign exchange reserve and jumps in unemployment during dark corners in the more open regime.     

Capital Flows Adjustment Policy in Slovenia: Assessment of Design and Efficiency

During the last decade many Central and East European (CEE) countries experienced strong foreign capital inflows. Slovenia was one of them. Sources of inflows in Slovenia changed radically, even though privatisation-driven inflows were absent, in contrast to other CEE countries. Since such inflows could have significant adverse effects on the performance of the economy, some policy measures were taken. This article presents an empirically tested assessment of policy for adjustment to surges in capital flows during the last decade. Speculative reversals, a decline in external competitiveness, exchange rate appreciation, loss of control over the monetary base and inflation are just some of the detrimental effects that can be provoked by surges in capital flows if the economy suffers from fundamental sectoral deficiencies. Empirical results indicated that Slovenia quite successfully mitigated the listed effects of excessive foreign exchange inflows. Efficient combination of direct and indirect adjustment methods succeeded in preventing the still vulnerable economy from suffering a major financial crisis and nominal currency appreciation (which was not the case in some other CEE countries) although there was some real appreciation.     

The Short‐term Determinants of Capital Flows for a Small Open Economy: The Case of Greece

This paper presents the factors driving capital flows inwards and outwards of a small open economy such as Greece during the period 1983–2009. Apart from the determinants of capital flows the possibility of speculative attacks is also considered. Applying the ordinary least squares (OLS) method it is found that variables linked to external factors such as the differential of domestic and foreign interest rates and financial crises, such as the Asian and Russian financial turmoil of 1997 and 1998 respectively, are the main factors influencing capital inflows and outflows in Greece during the period 1983–2009. Additionally the results of probit analysis support that the same factors are significant in determining the probability of speculative attacks to the Greek economy.     

Financial Openness and the Dutch Disease

This paper studies the relationship between the degree of financial openness and Dutch disease effects of capital inflows in developing countries. The results reveal that an increase in financial openness leads to an appreciation of the real exchange rate. In particular, the study shows that an increase in inflow of foreign direct investments (FDI) results in an appreciation of the real exchange rate in more financially open countries only. The results also suggest that there is a trade‐off between the resource movement effect and the spending effect in more financially open economies following an increase in FDI inflows, such that the more the tradable sector expands relative to the nontradable sector, the greater is the real exchange rate appreciation.     

The 2014–15 Financial Crisis in Russia and the Foundations of Weak Monetary Power Autonomy in the International Political Economy

ABSTRACT

This article contributes to international political economy debates about the monetary power autonomy (MPA) of emerging market and developing countries (EMDs). The 2014–15 Russian financial crisis is used as a case study to explore why an accumulation of large international reserves does not provide protection against currency crises and macroeconomic adjustments in EMDs. The analysis centres on the interplay between two dimensions of MPA: the Power to Delay and the Power to Deflect adjustment costs. Two structural factors condition Russia’s low MPA. First, the country’s subordinated integration in global financial markets increases its financial vulnerability. The composition of external assets and liabilities, combined with cross-border capital flows, restrict the use of international reserves to delay currency crises. Second, the choice of a particular macroeconomic policy regime embraced the financialisation of the – mainly state-owned – Russian banking sector, thus making it difficult to transform liquidity inflows into credits for enterprises. Russia’s main comparative advantage, hydrocarbon export revenues, is not exploited. The type of economy created due to the post-Communist transition means that provided ‘excessive’ liquidity remains in the financial system and is channelled into currency arbitrage. This factor increases exchange rate vulnerability and undermines Russia’s MPA.

Capital Inflows,Exchange Rate Flexibility and Credit Booms

Historically, capital flow bonanzas have often fueled sharp credit expansions in advanced and emerging market economies alike. Focusing primarily on emerging markets, this paper analyzes the impact of exchange rate flexibility on credit markets during periods of large capital inflows. It is shown that bank credit is larger and its composition tilts to foreign currency in economies with less flexible exchange rate regimes, and that these results are not explained entirely by the fact that the latter attract more capital inflows than economies with more flexible regimes. The findings thus suggest countries with less flexible exchange rate regimes may stand to benefit the most from regulatory policies that reduce banks' incentives to tap external markets and to lend/borrow in foreign currency; these policies include marginal reserve requirements on foreign lending, currency‐dependent liquidity requirements and higher capital requirement and/or dynamic provisioning on foreign exchange loans.     

Surviving Asymmetry in Capital Flows and the Business Cycles: The Role of Prudential Capital Controls

Past literature of different strands has pointed to a potential asymmetry: while portfolio capital inflows are largely irrelevant to the economy, capital outflows can cause recession. In a model with a convex investment and portfolio balance adjustment cost, and endogenous credit‐in‐advance constraint, we find that investment is determined solely by opportunity cost of physical capital unrelated to portfolio capital inflows when the constraint is slack. However, once credit availability is tightened up by capital outflows, the negative liquidity constraint dominates the opportunity‐cost factor, causing an economic downturn. Financial fragility against capital outflows is an outcome of pecuniary externalities, which, however, can be moderated by prudential capital controls. Even when exchange rates float freely, capital controls ease the macro‐stabilizing burden of monetary policy, as they help shield the economy from financial instability. Prudential tax on foreign debt is most preferred, and works the best when the exchange rate float is managed.     

Macroeconomic Effects of Capital Account Liberalization: the Case of Korea

The macroeconomic effects of capital account liberalization in Korea are examined. Simple data analysis suggests that capital account liberalization substantially changed the nature and composition of capital flows. Based on the VAR model, the authors find the following stylized facts. First, after capital market liberalization, capital flows become less driven by current account imbalances and therefore become more autonomous. Second, capital account liberalization significantly changes the effects of capital flows on macroeconomic variables. Third, capital account liberalization is highly related to consumption and investment booms, and subsequent appreciation of nominal and real exchange rates, which leads to the current account worsening. Finally, there is strong evidence of sterilized foreign exchange market intervention in response to capital inflows.     

Balance of payments accounting and exchange rate dynamics

The balance of payments is an accounting identity. Many wonder how the current and capital accounts, which add up to zero, can influence exchange rates. This paper shows how payment flows arising from balance of payments imbalances affect the demands for different currencies in the foreign exchange market over time. Based on a dynamical system approach, the paper demonstrates how international payments evolve depending on the joint dynamic behaviour of different balance of payments components. It finds that international payments and exchange rates interact in fundamentally different ways depending on whether a country restricts its capital inflows and outflows, whether capital flows are accommodating or autonomous and whether the exchange rate is fixed, flexible or, say, governed by a crawling peg. Empirical evidence from major industrial countries as well as from countries hit by currency crises support the paper's theoretical predictions.     

Competition Among Banks, Capital Requirements and International Spillovers

The design of prudential bank capital requirements interacts with the industrial organization of the banking sector, in particular, with the level of competition among banks. Increased competition leads to excessive risk-taking by banks which may have to be counteracted by tighter capital requirements. When capital requirements are internationally uniform but the levels of competition among banks in different countries are not, international spillovers arise on financial integration of these countries. This result begs a more careful analysis of the effect of financial liberalization on the stability of banking sectors in emerging countries. It also calls into question the merits of employing uniform capital requirements across countries that diverge in the industrial organization of their banking sectors.

The new IMF approach to capital account management and its blind spots: lessons from Brazil and South Korea

As emerging economies experience a boom in capital inflows, governments are increasingly concerned about their downsides. Even the IMF (International Monetary Fund), long a stalwart proponent of financial liberalization, has engaged in a new debate on capital flow management. Drawing lessons from empirical case studies on Brazil and South Korea, this paper finds that the new IMF framework remains insufficient in two main aspects. First, by defining ‘capital flow management measures’ (CFMs) as a temporary instrument embedded in an overall strategy of financial opening, the organization insists on the general advantages of financial liberalization, which poses serious limits to emerging economies’ policy space. Second, the Fund keeps on stressing a separation of prudential financial regulation, which should be permanent, and temporary CFMs. Yet, the case studies presented here show that, especially for emerging markets with rather open and sophisticated domestic financial markets, both types of measures are interdependent and overlapping. Additionally, we demonstrate the relevance of a third type of regulation, lying on foreign exchange (FX) derivatives instruments, which may also be required to effectively manage foreign investors’ portfolio reallocations and their impact.     

Sustainability of Monetary-cum-Exchange Rate Policy in China

This paper theoretically considers the long-run sustainability of China’s monetary-cum-exchange rate policy under the impossible trinity. Two different models are examined: One sterilizes current net foreign assets (NFAs) and the other focuses on NFAs realized in the previous period. Under the de facto opening of financial flows, sterilization yields a negative risk premium in uncovered interest parity (UIP) that triggers a feedback increase among capital inflows. Here, stability depends on the magnitudes and the combination of structural and policy parameters. It is shown that if current capital inflows are sterilized, the monetary-cum-exchange rate policy in China offers a sustainable solution for exchange rates that are relatively stringently managed. However, such a solution can be obtained for relatively flexible or moderately managed rates if sterilization policy is implemented on the previous period’s inflows.     

Speculative attacks with unpredictable or unknown foreign exchange reserves

During a currency crisis, speculators usually do not know the value of a central bank's foreign exchange reserves. In this paper I show that modelling speculators as having imperfect knowledge of reserves enriches the predictions of the classical model of speculative attacks. With realistic lags in reserve reporting and costs to unsuccessful speculation, successful speculative attacks will involve a jump depreciation, unsuccessful attacks may occur, attacks may occur when fundamentals are improving, attacks may not be preceded by large increases in interest rates, and fixed exchange rates may be abandoned with no attack and no decline in the money supply.

Why peg? The role of capital mobility and financial intermediation

Many economists argue that the growth of international capital mobility has made the maintenance of pegged exchange rates more costly, forcing developing states to choose alternative arrangements. But some states do not simply abandon pegged exchange rates as their exposure to capital mobility rises. Some states abandon pegs long before a crisis can erupt, while others maintain pegs until the speculative pressures became unbearable. Why, in an environment of growing capital mobility, do some states maintain pegs longer than others do? One reason is that the more that bank lending dominates investment in a country, the more likely that state is to hold on to a pegged exchange rate. When banks have accumulated significant amounts of foreign debt they lobby for exchange rate stability. In a bank‐dominated financial system, a concentrated banking sector can organize easily and use its crucial role in the economy to exert influence over economic policy. This article presents new evidence from statistical tests on 61 developing countries that confirm that states with deeper banking systems are more likely to peg their exchange rates, in spite of growing capital mobility.     

Exchange rate policies during transition from plan to market

This paper reviews the exchange rate policies adopted in the early years of transition, paying attention to the dilemmas concerning the degree of convertibility, the initial choice of exchange rate regime and the required scale of devaluation. The initial liberalization and devaluation were then followed by a period of real exchange rate appreciation, which was accompanied by improving export performance; this second phase has policy implications that are briefly discussed. Throughout, a key constraint is the inability of the central bank to target simultaneously monetary aggregates, interest rates and the exchange rate. In the presence of large capital inflows the authorities have to manage the exchange rate and domestic monetary policy in order to keep inflation acceptably low while maintaining international competitiveness.
