On the Transmission Mechanism of Monetary Constraints to the Real Side of the Economy

Contrary to the predictions of the theory underlying international finance, inflows of capital triggered by financial liberalisation have neither equalised real interest rates nor increased income growth in many emerging economies. We explain this puzzle by developing a model that combines the balance‐of‐payments constraint approach to economic growth with a less stringent version of the real interest rate parity hypothesis. The model’s foundations are based on robust empirical findings or well‐established macroeconomic models. We show that a perverse combination of income elasticities of demand for imports and exports generates slow income growth and high real interest rates. As domestic income grows and imports rise faster than exports, the real exchange rate is expected to depreciate in order to clear the balance of payments (or the foreign exchange rate market). An incipient capital outflow arises and interest rates increase. Faster adjustment in capital rather than in the goods market therefore generates a higher real interest rate differential between the domestic small open‐economy and the rest of the world. The long run analysis shows that a constant degree of risk aversion implies a positive equilibrium real interest rate differential that affects economic growth. A permanent increase in default risk driven by persistent current account imbalances thus impacts on long run growth. The model’s results are illustrated with evidence from the three major Latin America economies: Argentina, Brazil and Mexico.     

Speculative Efficiency and the Exchange Rate: Some Evidence Since the Float

This paper considers whether the speculative efficiency hypothesis holds in the foreign exchange market since the floating of the Australian dollar in December 1983. For the post-float period as a whole, the speculative efficiency hypothesis can be rejected in the 30-day market but not in the 15-day or 90-day markets. Evidence of a structural change in the market in February 1985—the time of the first major depreciation - was also found.     

The impact of interest rate and exchange rate volatility on banks' stock returns and volatility: Evidence from Turkey

This paper investigates the effects of interest rate and foreign exchange rate changes on Turkish banks' stock returns using the OLS and GARCH estimation models. The results suggest that interest rate and exchange rate changes have a negative and significant impact on the conditional bank stock return. Also, bank stock return sensitivities are found to be stronger for market return than interest rates and exchange rates, implying that market return plays an important role in determining the dynamics of conditional return of bank stocks. The results further indicate that interest rate and exchange rate volatility are the major determinants of the conditional bank stock return volatility.     

Tests of real interest parity in international currency markets

The purpose of this paper is to examine the behavior of real bilateral exchange rates for major currencies and test the hypothesis of real uncovered interest parity with risk premia, and forward looking expectations. It is plausible that the hypothesis of rational expectations cannot be rejected given the unit root nonstationarity of real exchange rates but it is not unlikely that unit root nonstationarity may be due to rational expectations in foreign exchange markets.     

Short-term eurocurrency rate behavior and specifications of cointegrating processes

This article presents empirical evidence on short-term behavior based on seven Eurocurrency market rates. Empirical analysis suggests that there is two-dimensional cointegration. First, the domestic short-term interest rate is cointegrated with longer-term interest rates within a particular country. Second, the domestic short-term interest rate is cointegrated with the comparable foreign short-term interest rate adjusted for the foreign exchange forward premium (discount). The empirical evidence confirms that an error-correction model combining both dimensional market-correcting processes better explains short-term interest rate movements.     

The reaction of spot and forward rates to new information

This paper examines the impact of new information on the term structure of exchange rates. In particular, the response of spot and forward exchange rates to anticipated and unanticipated weekly U.S. and Canadian money growth announcements, and the speed of adjustment of the foreign exchange market to these announcements are investigated. The results indicate that the unanticipated component of the announced changes in the U.S. money supply has an immediate negative effect on the foreign value of the U.S. dollar. This is entirely consistent with the assetmarket theory of exchange rate determination that postulates that exchange rates immediately adjust to reflect ‘new information’. The response of the forward market, however, appears to be weaker, lending support to the overshooting hypothesis.     

Foreign interest rate shocks and exchange rate regimes in East Asia

Using a theoretical dynamic stochastic general equilibrium model and an empirical panel vector autoregression, we assess the transmission of foreign real interest rate shocks on the volatility of various key macroeconomic variables in nine small open economies in East Asia taking into account the role of exchange rate regimes. Both the theoretical and empirical findings confirm the hypothesis that flexible exchange rate may work as a shock absorber when the economy is hit by foreign real interest rate shocks. The findings suggest a clear trade-off between the volatility of real exchange rate and real output to foreign interest rate shocks, both the US and G7 real interest rates, where the responses of real output are mitigated in countries that have more flexible exchange rate regime.     

Purchasing power parity and uncovered interest parity: The Spanish case

This paper examines whether the purchasing power parity (PPP) hypothesis holds in the long run when traded and non-traded goods are distinguished. Moreover, this hypothesis is analyzed jointly with the uncovered interest parity (UIP). The period from January 1986 to December 1995 was studied using monthly data corresponding to the consumer price index, short- and long-term interest rates, and spot exchange rates for Portugal, France, Italy, Germany, and Great Britain with each relative to Spain. Using Johansen's multi-equational cointegration technique, it was found that PPP does not hold even with the explicit consideration of the distinction between traded and non-traded goods as well as the difference between domestic and foreign interest rates. Furthermore, these two factors generate a systematic deviation between exchange rates and PPP.     

Real interest rate equalization: some empirical evidence from the three major world financial markets

This article examines the linkage of real interest rates of the three major world financial markets (USA, Japan and the UK) with the use of cointegration methods. Unlike previous works, the investigation uses a trivariate vector autoregressive (VAR) model in which a constant term in the common stochastic trends space is excluded. Based on data generated after the liberalization of Japan's foreign exchange market at the end of 1980 (1981:1–1998:12), the article finds some empirical evidence indicating that the extent of the departure from the long-run real interest rate equalization (RIE) is not very large, although the null hypothesis of the long-run RIE is rejected in most cases.     

Using survey data to test market efficiency in the foreign exchange markets

The paper uses cointegration methods to test the market efficiency hypothesis (MEH) in the foreign exchange markets. Four exchange rates are considered-all relative to the US dollar: BP, DM, SF and JY. Survey data on expectations are used to see whether the violation of the MEH is due to expectational errors or risk premia. The results differ for the one-week ahead and the one-month ahead forecasts. With the weekly data we conclude that it is risk premia, and with the monthly data it is both expectational errors and risk premia that account for the violation of the MEH. Given the volatility of the exchange markets, it appears that forecasts over an extended period fail tests of rationality, but one-week ahead forecasts do not fail such tests.     

BLACK MARKET EXCHANGE RATES AND CAPITAL MOBILITY IN ASIAN ECONOMIES

This paper examines whether foreign exchange black markets have eroded the effectiveness of capital controls and contributed to an increase in the effective degree of capital mobility in a sample of Asian countries. Comparing the uncovered interest parity forecast errors between the official and black market exchange rates suggests that in those countries with more stringent capital controls, foreign exchange black markets have reached a maturity level to threaten the effectiveness of those controls.     

EXCHANGE RATE STABILISATION, LEARNING AND THE TAYLOR PRINCIPLE

The paper explores whether central banks can keep their interest rates independent from given foreign rates, and to what extent interest policies designed to stabilise nominal exchange rate changes can be applied instead of, or in addition to, the traditional interest rate response to inflation gaps. This modification of a Taylor Rule is analysed in a simple macro model with some New Keynesian features. Information is imperfect; agents cannot build rational expectations but try to learn 'true' market relations. Results show that the Taylor Principle can be generalised in an open economy with flexible exchange rates.     

Market reactions to U.S. weekly money supply announcements after the introduction of contemporaneous reserve requirements an empirical note

Movements across the nominal term structure of U.S. interest rates have continued to be positively correlated with weekly money surprises post-CRR. Bond and foreign exchange market evidence suggests that these may no longer be movements in the real term structure.     

UNIFICATION OF CHINA'S FOREIGN EXCHANGE RATES

This paper studies China's foreign exchange market before and after the 1994 unification of the official and swap exchange rates. Examining segmentation as well as linkages among the foreign exchange adjustment centers (FEACs) reveals that the linkages were not strong enough to eliminate or narrow price differentials among FEACs. Hence, improving the foreign exchange market's efficiency requires a reform to unify the swap rates. This paper discusses the unification's implications for inflation, monetary policy, and current account convertibility.     

Testing the relative purchasing power parity hypothesis: the case of Korea

This study examines the relative purchasing power parity (PPP) hypothesis using the data from the Korean won–US dollar and the Korean won–Japanese yen foreign exchange markets. We extract proxies for inflation from stock market returns of Korea, the United States and Japan based on the method used by Chowdhry, Roll and Xia in 2005. We explicitly test the relative PPP hypothesis in light of the short-run price volatility using monthly, bimonthly and quarterly data from 1 January 1998 to 31 December 2012. Our findings suggest that the empirical test results from the entire sample period do not support the relative PPP hypothesis. However, the results from the sample period excluding the Asian Financial Crisis period show that the relative PPP hypothesis holds for the Korean won–US dollar market with a moderate magnitude of inflation impact, but not for the Korean won–Japanese yen market. Abrupt changes in exchange rates during the crisis period may have affected the relationship between inflation and exchange rates. This result also suggests that factors other than inflation might have affected the Korean won–Japanese yen exchange rate.     

Robust tests for unit roots in the foreign exchange market

Empirical studies that have tested for unit roots in foreign exchange rate data have assumed independent and identically distributed errors in order to apply Dickey-Fuller test procedures. This assumption ignores the temporal dependence of the error sequence present in many simple efficient market tests, as discussed in Hansen and Hodrick (1980), as well as Krasker (1980). In this paper we apply unit root test statistics that allow for heterogeneously distributed and mildly dependent error processes, and thus provide superior tests of the unit root hypothesis in the case of foreign exchange rates.     

The impact of foreign macroeconomic news on financial markets in the Czech Republic, Hungary, and Poland

In this paper, we investigate the effects of euro area and US macroeconomic news on financial markets in the Czech Republic, Hungary, and Poland (CEEC-3) from 1999 to 2006. Using a GARCH model, we examine the impact of news on daily returns of 3-month interest rates, stock market indices, exchange rates versus the euro, and the US dollar. First, both US and European macroeconomic news has a significant impact on CEEC-3 financial markets. Second, the process of European integration is accompanied by an increasing importance of euro area news relative to US news. Third, there are country-specific differences: for example, the Czech stock market is relatively more affected by foreign news since the Copenhagen Summit in December 2002. In general, our results support the hypothesis of a deepening euro area influence on the CEEC-3 over time and a corresponding reduction in the relative importance of US shocks.     

From Peg to Float: Exchange Market Pressure and Monetary Policy in the Czech Republic

Exchange market pressure (EMP) in the Czech Republic is calculated for 1995–2006, when the Czech National Bank transitioned to inflation targeting (IT). EMP is a useful indicator of incipient foreign exchange market pressures, a signal of the need for policy adjustments and a clear delineator of monetary policy regime change. VAR estimates clearly identify quite different policy responses during the two regimes. During 1995–98, interest rate and domestic credit responses to EMP were statistically significant and in accord with traditional theory, i.e. domestic credit creation and interest rates were managed to maintain the exchange rate target as if policymakers were explicitly responding to changes in EMP. During the 1998–2006 IT regime there is a link between domestic credit creation and EMP, with no interest rate effects. Exchange market interventions were incidental and supportive of IT goals. Impulse response functions mirror the VAR and Granger causality results.     

Forward Speculation, Excess Returns, and Exchange Rate Variability: The Role of Risk Premiums

The paper reconsiders the unbiasedness hypothesis in the foreign exchange market. Within the context of a conventional model of exchange rates, risk premium shocks are constrained to have no permanent effects on the spot rate. Using monthly data from the post-floating period, the paper estimates risk premiums for the dollar rates of the yen, mark, and pound. Risk premium innovations seem to explain a modest proportion of short-term variability of exchange rate changes and excess returns. However, risk premiums may explain serial correlations in excess returns.     

人民币升值对中国股票市场的影响机制分析

汇率和股票价格波动之间具有很强的相关性,汇率的变动会通过贸易、货币供应、利率、心理预期等机制引起股价的波动。虽然受外汇管制、金融市场发展程度及市场开放度的影响,人民币汇率通过传统的传递机制对中国股票价格波动受到一定限制,但在人民币持续升值的压力下,外资以直接和间接方式对国内股票市场造成的冲击已是不争的事实。
