The January effect in the foreign exchange market: Evidence for seasonal equity carry trades

In this study, we investigate monthly seasonality in the foreign exchange market. Given the well-known recurrent higher returns in some month than in others in stock markets around the world, we consider it likely that a seasonal outperformance of a country’s stock market over another is associated with similar seasonal patterns in capital flows and exchange rates. A seasonal profit (carry trade) opportunity can be created by the simultaneous appreciation of a country’s currency and the outperformance of its stock market. By focusing on the world’s key currency pairs, the US dollar-Deutsche mark and the US dollar-euro, and by using a Markov-switching framework, we document persistent January and December effects in the foreign exchange market from 1971 to 2017. Analysis of the German-US stock returns differential and their bilateral capital flows reveal similar month effects in 65% of the whole sample.     

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.     

Financial integration and exchange rate determination: a Brazilian case study

This paper investigates the impact on exchange rate determination of two recent changes in developing and emerging countries’ financial integration: first, the rising volume and heterogeneity of short-term portfolio flows; second, foreign investors’ increased exposure to domestic rather than foreign currency assets. In its analysis of Brazil, the paper shows that both changes have potentially destabilizing implications for the exchange rate and may create the risk of self-feeding bubble dynamics leading to large and sudden swings in exchange rates. The results have important implications for the regulation of international capital movements and choice of exchange rate regime.     

Liquidity management of foreign exchange reserves in continuous time

In order to cope with daily foreign currency exchange payments or trades and avoid liquidity crisis, central banks need to maintain the liquidity of foreign exchange reserves. In this paper, we develop a Foreign Exchange Reserves Liquidity Management (FERLM) model based on stochastic process by introducing a foreign exchange factor. We also generate a feasible target proportion of the liquidity reserve to total foreign exchange reserves, by seeking the balance between capital gains of holding foreign exchange reserves and losses of liquidity insufficiency.     

Transmission of monetary policy and exchange rate shocks under foreign currency lending

This paper analyses the differences in reaction of domestic and foreign currency lending to monetary and exchange rate shocks, using a panel VAR model estimated for the three biggest Central and Eastern European countries (Poland, the Czech Republic and Hungary). Our results point toward a drop in domestic currency loans and an increase of foreign currency credit in reaction to monetary policy tightening in Poland and Hungary, suggesting that the presence of foreign currency debt weakens the transmission of monetary policy. A currency depreciation shock leads to an initial decline in foreign currency lending, but also in loans denominated in domestic currency as central banks react to a weaker exchange rate by increasing the interest rates. However, after several quarters, credit in foreign currency accelerates, indicating that borrowers start using it to substitute for depressed domestic currency lending.

The foreign exchange constraint,suppression of the trade deficit and the shadow price of foreign exchange in a fix-price economy

The foreign exchange gap is analysed as a possible feature of a fix-price economy. The implications of closing the gap by means of import rationing are then discussed. Finally, a set of shadow rates of exchange is derived. These shadow prices are conditional on the prevailing regimes, and include the paradoxical possibility of a negative shadow rate of exchange.     

Exchange Rates and Outward Foreign Direct Investment: US FDI in Emerging Economies

This paper investigates the effect of exchange rates on US foreign direct investment (FDI) flows to a sample of 16 emerging market countries using annual panel data for the period 1990–2002. Three separate exchange rate effects are considered: the value of the local currency (a cheaper currency attracts FDI); expected changes in the exchange rate (expected devaluation implies FDI is postponed); and exchange rate volatility (discourages FDI). The results reveal a negative relationship between FDI and more expensive local currency, the expectation of local currency depreciation, and volatile exchange rates. Stable exchange rate management can be important in attracting FDI.

The comovement between exchange rates and stock prices in the Asian emerging markets

This study investigates the comovement between exchange rates and stock prices in the Asian emerging markets. The sample covers major institutional changes, such as market liberalization and financial crises, so as to examine how the short-term and long-term relations change after such events. The autoregressive distributed lag (ARDL) model proposed by Pesaran et al. (2001) is adopted, which allows us to deal with structural breaks easily, and to handle data that have integrals of different orders. Interest rates and foreign reserves are also included in the analysis to reduce potential omitted variable bias. My empirical results suggest that the comovement between exchange rates and stock prices becomes stronger during crisis periods, consistent with contagion or spillover between asset prices, when compared with tranquil periods. Furthermore, most of the spillovers during crisis periods can be attributed to the channel running from stock price shocks to the exchange rate, suggesting that governments should stimulate economic growth and stock markets to attract capital inflow, thereby preventing a currency crisis. However, the industry causality analysis shows the comovement is not stronger for export-oriented industries for all periods, such as industrials and technology industries, thus implying that comovement between exchange rates and stock prices in the Asian emerging markets is generally driven by capital account balance rather than that of trade.     

THE EAST ASIAN CURRENCY CRISIS: CAUSES AND LESSONS

Financial deregulation and capital-account liberalization preceded speculative currency attacks in Thailand. A combination of de facto fixed exchange rates and high rates of interest generated excessive capital inflows, which led to too much liquidity chasing bad investments. The under-supervised and over-guaranteed financial sector extended loans excessively, particularly for non-productive, speculative purposes. Non-transparent practices, in the form of weak disclosure of institutions' true balance sheets and insider relations, masked these poor investments. The buildup of short-term, unhedged debt left East Asian economies vulnerable to a sudden collapse of confidence. Currency attacks ran down official foreign exchange reserves. Rapid capital outflows and the consequent depreciation of currencies exacerbated the strains on private sector balance sheets. The policy lessons are to (i) use macroeconomic policy to avoid excessive capital inflows and currency overvaluation, (ii) strengthen the financial system, with proper disclosure and accounting requirements, stringent loan classification and provisioning rules, and capital adequacy requirements, prior to capital-account liberalization, (iii) stabilize exchange rates based on currency baskets that reflect trade and investment linkages, and (iv) develop regional. financial cooperation with regional surveillance and peer pressure to maintain policy discipline.     

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.     

Smuggling, non‐fundamental uncertainty, and parallel market exchange rate volatility

Abstract.  We explore a model where smuggling and a parallel currency market arise, owing to government restrictions that prevent agents from legally holding foreign exchange. Despite such restrictions, agents are able to diversify their savings, holding both domestic and parallel foreign cash, basing their portfolio allocation on current and prospective parallel exchange rates. We attribute movements in parallel rates to non‐fundamental uncertainty. The model generates equilibria with both positive and negative parallel premia and correlations between illegal trade and the premium. The model has the novel implication that currency speculation drives smuggling, affecting real activities in all sectors of the economy. JEL classification: F31     

Bond risk premia, macroeconomic fundamentals and the exchange rate

We propose a two-country no-arbitrage term-structure model to analyze the joint dynamics of bond yields, macroeconomic variables and the exchange rate. The model allows to understand how exogenous shocks to the exchange rate affect the yield curves, how bond yields co-move in different countries and how the exchange rate is influenced by interest rates, macro-economic variables and time-varying bond risk premia.Estimating the model with US and German data, we find that time-varying bond risk premia account for a significant portion of the variability of the exchange rate: apparently, a currency tends to appreciate when investors expect large capital gains on long-term bonds denominated in that currency. A number of other novel empirical findings emerge.

Currency restrictions,government transaction policies and currency exchange

Summary. We study how currency restrictions and government transaction policies affect the values of fiat currencies in a two country, divisible good, search model. We show that these policies can generate equilibria where both currencies circulate as medium of exchange and where currency exchange occurs between citizens of different countries. Restrictions on the internal use of foreign currency can cause the domestic currency to be relatively more valuable to domestic agents while taxes on domestic currency create an incentive for home agents to hold foreign currency. We demonstrate that some policies increase prices and lower welfare while others do the reverse. Received: September 5, 2001; revised version: March 1, 2002     

The demand for money and the real exchange rate misalignments in emerging European countries: A nonlinear approach

This paper investigates the extent to which domestic and foreign money balances in emerging European countries are influenced by foreign exchange considerations. A well-specified and stable relationship between real money demand and the exchange rate can be perceived as an important part of a successful monetary policy. This study examines the long-run determinants of real exchange rates (RERs) associated with the behavioral equilibrium exchange rate (BEER) approach and identifies currency misalignments in these countries. The misalignment is later used to test the nonlinear behavior of the demand for money. The results indicate that the RER misalignments have a significant impact on domestic money demand. When the currencies are overvalued, there is a reduction in domestic money demand, and when they are undervalued, there is an increase in domestic money demand. Furthermore, it can be concluded that overvaluation causes an increase in foreign money demand indicating a shift of preference from domestic to foreign currency.     

OPTIMAL EXPORT AND HEDGING DECISIONS WHEN FORWARD MARKETS ARE INCOMPLETE

This paper examines the behaviour of the competitive firm that exports to two foreign countries under multiple sources of exchange rate uncertainty. There is a forward market between the home currency and one foreign country's currency, but there are no hedging instruments directly related to the other foreign country's currency. We show that the separation theorem holds when the firm optimally exports to the foreign country with the currency forward market. The full‐hedging theorem holds either when the firm exports exclusively to the foreign country with the currency forward market or when the relevant spot exchange rates are independent. In the case that the relevant spot exchange rates are positively (negatively) correlated in the sense of regression dependence, the firm optimally opts for a short (long) forward position for cross‐hedging purposes.     

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.

A prototype model of the foreign exchange market of Canada: Forecasting capital flows and exchange rates

A balance-of-payments structural model of the foreign exchange market of Canada, endogenizing capital flows, the spot and forward exchange rates and the entities of the monetary sector, is developed using quarterly data for 1971–81. The capital flows have been disaggregated into ten categories and the exchange rates of the Canadian dollar have been analysed against five major currencies. While the model does not adhere strictly to purchasing power or interest rate parity, it does recognize them and it also incorporates other economic fundamentals, expectations and risk. Government interventions, although generated endogenously, are quantified implicitly and globally. The model tracks the post-Bretton Woods in-sample experience and generates ex post predictions reasonably well.
