“New” monetary policy instruments and exchange rate volatility

Turkish economy has been suffering from rises in financial flows since the last two decades that these flows have raised financial stability challenges across emerging economies including Turkey. Regarding the ability of the central banks to decrease the financial risks including volatile exchange rate, the Central Bank of the Republic of Turkey has designed and implemented a new policy mix. In this study, we investigated the effect of new policy instruments (IRC, RRR and ROM) on the volatilities of US dollar, euro, British pound and basket rate for Turkish economy between January 2, 2002 and December 9, 2014 by using ARMA-GARCH, ARMA-EGARCH and SWARCH models. From the estimation results, we could not reach enough evidence that the IRC and RRR instruments could decrease the volatilities of exchange rates under investigation while the ROM instrument was successful, especially on US dollar and basket rate. We also found strong evidence in favour of asymmetric volatility, indicating that the positive shocks led to greater exchange rate volatility than negative ones.     

Third-country exchange rate volatility and Japanese–US trade: evidence from industry-level data

As an important economic power globally as well as within Asia, Japan is susceptible to fluctuations in the yen versus both the dollar and its neighbours’ currencies. The resulting risk, from both sources, might, therefore, have important effects on Japanese trade. This study incorporates third-country exchange rate volatility (both yen-renminbi and dollar-renminbi) into a reduced form trade model for industry trade between the US and Japan. As was the case with a previous study that did not include these effects, our cointegration analysis finds that most industries are unaffected by risk. Third-country effects are, however, significant in a number of cases. Interestingly, a large share of US industries find that exports increase due to third-country risk, suggesting that this volatility is encouraging traders to reorient their trade markets by substitution.     

Portfolio flows and the US dollar–yen exchange rate

This paper investigates the effects of portfolio flows on the US dollar–Japanese yen exchange rate changes over the period 1988:01–2011:04. Using a time-varying transition probability Markov-switching framework, the results suggest that the impact of portfolio flows on the dollar–yen exchange rate changes is state-dependent. In particular, the results show that portfolio inflows from Japan toward the US, more than monetary variables, strengthen the probability of remaining in the dollar–yen appreciation (low volatility) state. Therefore, credit controls on the flows can be used as a policy tool to pursue economic and financial stability.     

Money demand instability and real exchange rate persistence in the monetary model of USD–JPY exchange rate

This paper proposes a hybrid monetary model of the dollar–yen exchange rate that takes into account factors affecting the conventional monetary model's building blocks. In particular, the hybrid monetary model is based on the incorporation of real stock prices to enhance money demand stability and also, productivity differential, relative government spending, and real oil price to explain real exchange rate persistence. By using quarterly data over a period of high international capital mobility and volatility (1980:01–2009:04), the results show that the proposed hybrid model provides a coherent long-run relation to explain the dollar–yen exchange rate as opposed to the conventional monetary model.     

Foreign exchange market interventions and the $–¥ exchange rate in the long run

This article examines whether foreign exchange market interventions conducted by the Bank of Japan are important for the dollar–yen exchange rate in the long run. We rely on a re-examination of the empirical performance of a monetary exchange rate model. This is basically not a new topic; however, we focus on two new questions. First, does the consideration of periods of massive interventions in the foreign exchange market uncover a potential long-run relationship between the exchange rate and its fundamentals? Second, do Forex interventions support the adjustment towards a long-run equilibrium value? Our results suggest that taking periods of interventions into account within a monetary model does improve the goodness of fit of an identified long-run relationship to a significant degree. Furthermore, Forex interventions increase the speed of adjustment towards long-run equilibrium in some periods, particularly in periods of coordinated forex interventions. Our results indicate that only coordinated interventions seem to stabilize the dollar–yen exchange rate in a long-run perspective.     

Exchange rate volatility–economic growth nexus in Uganda

The global financial crisis has disrupted trade and capital flows in most developing economies, resulting in an increased volatility of exchange rates. We develop an autoregressive distributed lag model to investigate the effect of exchange rate volatility on economic growth in Uganda. Using data spanning the period 1960–2011, we find that exchange rate volatility positively affects economic growth in Uganda in both the short run and the long run. However, in the short run, political instability negatively moderates the exchange rate volatility–economic growth nexus. These results are robust to alternative specifications of the economic growth model.     

Do sticky prices increase real exchange rate volatility at the sector level?

We introduce the real exchange rate volatility curve as a useful device to understand the relationship between price stickiness and the fluctuations in Law of One Price deviations. In the presence of both nominal and real shocks, the theory predicts that the real exchange rate volatility curve is a U-shaped function of the degree of price stickiness. Using sector-level US–European real exchange rate data and frequency of price changes, we estimate the volatility curve and find the predominance of real effects over nominal effects. Good-by-good variance decompositions show that the relative contribution of nominal shocks is smaller at the sector level than what previous studies have found at the aggregate level, consistent with significant averaging out of good-specific real microeconomic shocks.     

Does black market exchange rate volatility deter the trade flows? Iranian experience

Previous studies that investigated the impact of exchange rate volatility on the trade flows, employed official exchange rate data to construct a measure of exchange rate uncertainty. In this paper we show that in countries that there is a black market for foreign exchange, the black market exchange rate volatility could have adverse effect on the trade flows. We show this by using data from Iran and cointegration analysis.     

Real exchange rate and export performance in Argentina, 2002–2008

Between 2002 and 2008, Argentina experienced a phase of very high and sustained economic growth. During this period, macroeconomic policy aimed to preserve a stable and competitive real exchange rate (SCRER). There is controversy on whether the SCRER policy was a key factor fostering growth and, even more, on whether it helped promote the expansion of tradable activities and exports. We use a methodology to detect episodes of export surges among Argentina’s export industries and find that labor-intensive industries—especially low- and medium-technology manufactures—experienced the highest proportion of export surges within this period. We also find that between 1980 and 2015, the highest proportion of surges in total exports occurred during the 2003–8 period. The performance of export of services was also particularly dynamic during this period. This evidence suggests that the SCRER policy was instrumental for export surges in Argentina during 2002–8.     

Analyzing time–frequency relationship between interest rate,stock price and exchange rate through continuous wavelet

In this study we investigate and identify the patterns of co-movement of interest rate, stock price and exchange rate in India in the period between July 1997 and December 2010 using the cross-wavelet power, the cross-wavelet coherency, and the phase difference methodologies. Our empirical findings suggest that stock prices, exchange rates and interest rates are linked. The cross wavelet results show that stock price movements are lagging both to the exchange rate and interest rate fluctuations. The interest rate lead over the stock price movements is even clearer, especially after 2006, and it suggests that the stock market follows the interest rate signals. Comparing results of WTC and XWT, we find very clear results of phase difference of lead–lag relationship between stock prices, exchange rates and interest rates.     

The internal and external equilibrium exchange rate of RMB: 1982–2010

This paper estimates fundamental equilibrium exchange rate of RMB based on internal and external balance of China’s economy. The findings indicate that RMB real exchange rate is overvalued in the period of 1982–1991, but the extent of the undervaluation has an enlarging trend since 2004. Then, we put forward a new theory called “Prior Equilibrium Exchange Rate” and apply it to RMB, finding that real effective exchange rate of RMB need to be appreciated about 20% between 2008 and 2010, and the appreciation range of bilateral nominal exchange rate between RMB and the world’s key currencies depends on the objective functions of the government. Policy implication indicates that decision makers need to refer to equilibrium exchange rate which is derived from different theories and to make great efforts to adjust it towards equilibrium level and establish RMB “Prior Equilibrium Exchange Rate.” Meanwhile, policymakers should implement a potential objective interval system of exchange rate appreciation. The appreciation range of bilateral exchange rate of RMB against USD from 2008 to 2010 may be set between 6% to 10%.     

US–Indonesia trade at commodity level and the role of the exchange rate

Previous studies that assessed the impact of currency depreciation on inpayments and outpayments of Indonesia with her major trading partners did not find much significant results, especially in the trade with the United States. We wonder whether insignificant link between the real rupiah-dollar rate and Indonesia’s inpayments and outpayments with the United States is due to aggregation bias. To answer this question, we disaggregate the trade flows between the two countries by commodity and consider the sensitivity of inpayments of 108 US exporting industries and outpayments of 32 US importing industries from Indonesia. We find that most industries respond to exchange rate changes in the short run. In the long run, however, 32 inpayments schedule and 17 outpayments schedule are significantly affected. A 1% real depreciation of the dollar was found to improve US trade balance by 1.8%.     

Growth under exchange rate volatility: Does access to foreign or domestic equity markets matter?

Employing a firm-level dataset, this paper explores the effects of exchange rate volatility on the growth performances of domestic versus foreign, and publicly traded versus non-traded private manufacturing firms in a major developing country, Turkey. The empirical results using dynamic panel data estimation techniques and comprehensive robustness tests suggest that exchange rate volatility has a significant growth reducing effect on manufacturing firms. However, having access to foreign, and to a lesser degree, domestic equity markets is found to reduce these negative effects at significant levels. These findings continue to hold after controlling for firm heterogeneity due to differences in export orientation, external indebtedness, profitability, productivity, size, industrial characteristics, and time-variant institutional changes.     

Malaysia-EU trade at the industry level: Is there an asymmetric response to exchange rate volatility?

Aftab et al. (Empirica 43:461–485, 2016) in this journal assessed the impact of exchange rate volatility on Malaysia-EU trade at commodity level using the linear ARDL approach of Pesaran et al. (J Appl Econom 16:289–326, 2001) and did not find significant effects in most of the 81 Malaysian exporting and 66 importing industries. In this paper, we argue for asymmetric effects of exchange rate volatility on the same industries’ trades which implies using Shin et al.’s (Festschrift in Honor of Peter Schmidt, Springer, New York, 2014) nonlinear ARDL approach. While we find short-run asymmetric effects of volatility in almost all industries, we find evidence of adjustment asymmetry in 17 exporting and nine importing industries. We also find significant impact or short-run cumulative asymmetry in 12 exporting and six importing industries. The most important finding is significant long-run asymmetric effects in 36 Malaysian exporting industries and 25 Malaysian importing industries. Clearly, trade flows react to an increased exchange rate volatility differently than to a decreased volatility.     

A model of exchange rate policy: evidence for the US dollar–Greek drachma rate 1975–87

This paper represents an attempt to model movements of the exchange rate between the US dollar and Greek drachma. A stuctural model is set up, and then a reduced-form error correction(EC) speicifcation is derived. On the basis of co-integration test, the results do not support the existence of al long-run equilibrium relationship between the exchange rate and price differential. Furthermore, the instrumental variable estimation of the EC model indicates that the monetary authorities have pursued a short-run anti-inflationary exchange rate poilicy that appreciates the exchange rate in the presence of wage inflation as an attempt to mitigate the depreciating pressures on the domestic currency and thus to ease the adjustment required on Greek producers.     

Unconventional monetary policy and the dollar–euro exchange rate: further evidence from event studies

New evidence is presented on the impact on the US dollar–euro (USD–EUR) exchange rate of the unconventional monetary policy conducted by the US Federal Reserve (FED) and the European Central Bank (ECB). To that end, we employ an event study approach using daily the USD–EUR exchange rate for the period from 2 January 2007 to 31 January 2015. Our results indicate that the announcement and subsequent implementation of such measures by the ECB would have caused in general an appreciation of the dollar, while those by the FED would have caused a depreciation of the dollar.     

ECB monetary policy and the DM–dollar exchange rate: evidence from a Bayesian VAR

Since the start of the European Monetary Union (EMU) in January 1999, the DM has depreciated considerably against the currencies of major industrial countries. Whether there is a systematic failure of vector autoregressive (VAR) models fitted to the pre-EMU period to predict forward looking variables in the year 1999 is investigated. Conditional forecasts are used in order to capture the potential effects of real shocks and to assess the ECB's reaction to these shocks. The findings suggest that neither real shocks nor the actual ECB-policy reaction can explain the exchange-rate devaluation. This points to important effects of increased uncertainty following the regime shift resulting in an increased risk premium in the foreign exchange market.     

Unconventional monetary policy and the dollar–euro exchange rate: first results from time-series analysis

This article examines the impact on the US dollar–euro (USD–EUR) exchange rate of the unconventional monetary policy conducted by the US Federal Reserve (Fed) and the European Central Bank (ECB). To that end, we make use of time-series analysis to obtain a reasonable long-run and short run representation of the data generation process and use dummy variables to study how announcements about monetary policy changes can affect the USD–EUR exchange rate. Our results indicate that the announcement and subsequent implementation of such measures by the ECB would have caused an appreciation of the dollar, while those by the Fed would have caused a depreciation of the dollar.     

A cautionary note in using patterns of shocks to determine optimal exchange rate policy. An exploration of Nepalese and Indian exchange rate relations: 1964–1994

Nepal and India are developing countries in Asia whose (hard) peg has existed for almost forty years as well as no restriction on capital mobility between both countries. However, empirical results suggest that Nepal and India do not face symmetric patterns of shocks and are thus not suitable for a fixed exchange rate under this criteria. One possible explanation may be that the monetary authority plays some role in the short run to reduce the cost of the exchange rate regime. This suggests that some caution should be used in basing optimal exchange rate policy on this single criteria.     

China–US economic and trade relations,trade news,and short-term fluctuation of the RMB exchange rate

The trade war between the US and China affects the fluctuation of RMB exchange rate. We collect news on China–US trade policies and talks from January 2017 to July 2020. Results show that China–US dialogue and tariff imposition have the greatest impact on the percentage of RMB appreciation and depreciation. Additionally, tariff relaxation and increasing enterprise restrictions can cause a sharp appreciation and depreciation. “Policies” events and trade news from the US influence RMB fluctuations the most significantly. Finally, positive events cannot significantly cause RMB appreciation, but negative events can significantly cause RMB devaluation.
