The Southern African Customs Union is the oldest customs union in the world and the member states form a currency union with the South African Rand being the regional currency anchor. Therefore, currency movements amongst SACU member are dependent on the developments on the Rand which, in turn, can affect stock market development in the region. We examine the time-frequency relationship between exchange rates and stock market returns in SACU countries using continuous wavelet transforms. Our empirical analysis is two-staged. Firstly, we employ wavelet power spectrum to examine the time-frequency properties of the individual series. Secondly, we use wavelet coherence analysis and phase dynamics to examine the synchronization between the variables in a time-frequency space. Our findings show stronger (weaker) exchange rate-stock returns relations are found during periods of higher (lower) inflation whereas we observe a stronger (weaker) relationship during periods of lower interest rate environment. Moreover, we find more significant long-run relationships for countries with more independent monetary policy (South Africa and Botswana) whereas these relations are more prominent over the short-run for countries with pegged exchange rates (Eswatini and Namibia). We also observe that periods of oil and currency shocks impact the exchange rate-stock returns relationship in SACU countries with pegged exchange rates (Eswatini and Namibia). Our findings bear important implications for different stakeholders. For instance, this study has implications for exchange rate policy as it addresses the issue of whether the exchange rate can be used to improve market performance or exchange rate developments spillover into the stock market. Furthermore, corporate managers and stock market participants would be interested in our findings as it identifies periods of market inefficiency when exchange rates can be used to beat the stock market.

From 1996 to 2016, Brazil faced great fluctuations in both its exchange and interest rates and simultaneously a huge growth of its agriculture has taken place. Examining the literature that deals with the relationships among these three variables (interest rate, exchange rate and agriculture GDP) we verified that monetary and exchange shocks can affect directly and/or indirectly (through relative prices) the agriculture GDP. However, these effects can be coincident or contrary between them. What actually happened in Brazil from 1996 to 2016? This article aimed to access the direct and indirect effects of monetary and exchange rate shocks on Brazil´s agriculture GDP taking into consideration years ranging from 1996 thru 2016. Using quarterly data for the 1996-2016 period, autoregressive vector models (VAR and VEC) were estimated. The exchange rate and monetary shocks were analyzed considering three different interest rate types, namely: the current Brazil´s Federal Funds Rate (Nominal SELIC rate), real interest rate of agricultural loans, and ex-ante real interest rate. We also analyzed the effect of the exchange rate separately on prices paid and on prices received by the agriculture (both make up the relative prices of agriculture) using an ARDL (Distributed Lag Self-Regressive Model) model with monthly data. Our econometric results revealed that both direct and indirect effects of monetary shocks were negative on the agriculture growth while the direct and indirect effects of exchange rate shocks were mutually contradictory themselves on the Brazil´s agriculture GDP. Because of the technical changes that have taken place during the 2000s and the 2010s, which turned some of the most representative crops more dependent on imported inputs, and the hedging behavior that the firms have adopted during the first two decades of the 21st century, which protects them from exchange oscillations, the agricultural sector lost sensitivity to the exchange rate variations in some extent. Regarding policy implications, it could be said that monetary policy can be efficient in the promotion of the agricultural sector, and, in fact, Brazilian government has been doing such through the rural credit subsidized interest rate. Exchange policy, on the other hand, proved to be inefficient in favoring the agriculture, or, in other words, the government can freely exercise exchange policy without regards to harm the agricultural sector.

This paper uses the global vector autoregressive (GVAR) modelling approach to study (1) the effects of negative output shocks on Bangladesh's following trading partners on Bangladesh's economy: the United States, China, Eurozone, India and Saudi Arabia (2) positive global oil price shocks. To represent Bangladesh's macroeconomics, the GVAR model contains four key macroeconomic variables as endogenous variables. They are (1) real gross domestic product (GDP), (2) real exchange rate, (3) short-term interest rates, and (4) inflation. The specified GVAR model is estimated using quarterly data from 32 countries/regions from 1993Q4 to 2016Q4. The findings of this paper are consistent with theoretical predictions that external shocks can and will be transmitted to an open economy operating under a fixed or managed floating exchange rate system. For example, quantitatively, if the real output of Bangladesh's trading partners' falls by 1%, its output will fall by 0.39%, while the inflation rate of Bangladesh's trading partners' rises by 1%, and Bangladesh's inflation rate will increase by 1.38%. Although the negative output shock of the US economy will not significantly affect the Bangladeshi economy, the negative output shock of the Chinese economy will have a negative and significant effect on the Bangladeshi economy. The negative output shock on the US economy has caused the real exchange rate of Bangladesh's currency to appreciate and raised its short-term interest rate, although it is not statistically significant. Contrarily, a negative output shock to China or other economies devalues the real exchange rate of the Bangladeshi currency, although it is not statistically significant. However, Bangladesh's interest rates have not responded to negative output shocks from its trading partners (except the United States and Saudi Arabia), and they are not statistically significant. One policy implication of Bangladesh's inflation being overly sensitive to external inflation shocks is that Bangladesh can and should make its currency exchange rate more flexible to protect its economy from external price shocks. Unexpectedly, the external oil price shock did not seem to have a significant impact on the Bangladeshi economy. One explanation is that the impact of foreign inflation on Bangladesh's economy may have reflected the impact of oil prices. [ABSTRACT FROM AUTHOR]

The transmission mechanisms of monetary policy through the exchange-rate channel become operative when any change in the policy interest rate under inflation targeting leads to a change in the real interest rate. This change in the real interest rate, in turn, changes the real exchange rate, which affects the trade and capital flows and hence real output. Although such a linkage between the interest rate and trade-capital flows is well-developed in advanced economies, it remains debatable whether the suggested monetary policy transmissions mechanism involving the interest and exchange rates operates in emerging market economies, such as Thailand. This paper uses quarterly data for Thailand over the period 2000Q2-2017Q4 to investigate the extent to which the interest rate is effective in affecting the real exchange rate and trade flows under the present inflation targeting strategy of monetary policy in this country. The paper specifies and estimates a structural vector autoregression (SVAR) model with six endogenous variables, namely real output, prices, interest rate, real exchange rate, real exports and real imports, in the presence of two external variables, namely the world oil price and the US federal funds rate. The empirical results suggest that the change in the policy interest rate that the central bank of Thailand (Bank of Thailand) deploys as the instrument of monetary policy for price stability under flexible inflation targeting does not make significant contributions to the forecast error-variances of other endogenous variables in the system. These findings raise doubt about the effectiveness of the interest rate in influencing the real exchange rate and through it, trade flows, real output and the prices. However, as suggested in the extant literature on open-economy macroeconomics, both real output growth and inflation maintain feedback relations with changes in the real exchange rate, real exports and real imports.

Previous literature believes that a commercial depreciation is associated with higher financial premium and more depletion of foreign reserves. This study re-investigates this belief. Analytical results indicate that a commercial depreciation with higher financial premium and more depletion of foreign reserves depend on the combined influences of the conditions that individuals are impatient as well as foreign interest rates are bigger than time preference rates rather than only policies of commercial depreciation. Non-distortion taxation does not solve the balance-of-payments difficulties. An exact negative relationship between foreign reserves and the financial premium cannot be found. [ABSTRACT FROM AUTHOR]

Globalization of the early 1990s is thought to have caused the loss of monetary-policy independence in India. I find that Indias monetary-policy independence is anchored in the exchange-rate regime along with its state of foreign-exchange reserves, and not necessarily in globalization per se. India significantly followed US interest rates even in the absence of globalization in the 1960s when the country faced foreign-exchange constraints and maintained a fixed exchange rate. From the mid 1970s to the early 1990s, India exercised monetary-policy independence under a floating exchange-rate regime. The loss of monetary-policy independence since the early 1990s is not attributable to globalization per se, but mainly to the stable exchange-rate policy of India, which heavily resembles the policy of the 1960s.

The purpose of this paper is to re-examine the empirical relationship among alternative monetary aggregates (Ml and M2), output, prices, interest rates and exchange rates in India. The results of a five-variate vector error correction model are indicative of a bi-directional causality between each of the monetary aggregates and prices. Our findings of a feedback relationship make each of the monetary aggregates a poor intermediate target and informational variable. Moreover, contrary to most recent research in this area, the results are supportive of the real business-cycle view and the Keynesian monetary accommodation hypothesis rather than the monetarists' theory of the business cycle.
