Abstract
Purpose – While changes in stock prices are said to affect exchange rates, exchange rate changes are
also said to affect stock prices The purpose of this paper is threefold First, the authors review all
empirical literature by dividing them into two groups of univariate and multivariate studies Second,
a table which summarizes the main features of each study is provided to help future researchers to
have easy access to summary of each study Finally, a new direction for future research is proposed.
This new direction relies upon non-linear ARDL approach and shows how to investigate symmetric vs
asymmetric effects of exchange rate changes on stock prices.
Design/methodology/approach – The paper reviews existing published work and provides
suggestions for future research.
Findings – The paper reviews existing published work and provides suggestions for future research.
An application reveals that exchange rate changes have asymmetric effect on stock prices.
Originality/value – This is the first review paper on the relation between exchange rates and
stock prices.

I Introduction
One of the areas in financial economics that has received the largest attention is the link
between foreign exchange market and the stock market The easiest way to infer the
link is by a reference to portfolio approach to exchange rate determination Under this
approach wealth is one of the main determinants of the exchange rate An increase in
stock prices usually increases public wealth This in turn increases the demand for
money and therefore, interest rates By attracting international investment, domestic
currency appreciates On the other hand, depreciation of domestic currency can boost
exports and eventually profit of exporting firms High profits once announced, can
cause share prices to rise Furthermore, depreciation raises cost of imported inputs
This can increase production cost even to firms that are not export oriented If higher
costs result in lower profits or expectation of lower profits, share prices could be
affected For this reason stock prices could move in either direction
Clearly if one needs to test the link between stock prices and exchange rates, one has
to concentrate on the current floating exchange rate system that began in 1973 For this
reason, almost all studies have engaged in empirical analysis using data from post-1973
period While some have concentrated on the link between stock prices and exchange
rates at bilateral level, some have included additional determinants of stock prices For
this reason, we review the empirical literature between the two variables at bilateral

Trang 3level in Section 2 In Section 3 we review studies that have included other variables
in their models In Section 4 we propose a direction for future research and finally,
we concluded in Section 5 A table is provided in which all features of the reviewedstudies are summarized[1]
II Review of bivariate studiesPerhaps the first study that concentrated on the relation between stock prices andexchange rates is that of Aggarwal (1981) who used monthly data during the period1974-1978 from the USA By using an aggregate index of stock prices and effectiveexchange rate of the dollar he showed that there is a positive relation between the twovariables, i.e., dollar depreciation or a decline in the effective exchange rate of the dollarcaused stock price to decline The implication is that more firms were hurt bydepreciation than helped Exactly opposite was concluded when Soenen and Hennigar(1988) looked into the response of stock prices of seven industrial sectors in the USA tochanges in the value of the dollar The seven sectors were selected on the belief thatthey were affected heavily by international trade The seven sectors were automobile,computer, machinery, paper, textile, steel and chemical The finding that the relationbetween stock price of each sector and the value of the dollar was negative implied that
as dollar depreciates, every sector exports more and rips profit from trade
None of the studies mentioned above accounted for integrating properties of the twovariables nor for cointegration between them Thus, their findings could suffer fromspurious regression problem To resolve the issue, Bahmani-Oskooee and Sohrabian(1992) used monthly data from the period of 1973-1988 to show that index of S & P 500and the effective exchange rate of the dollar are non-stationary variables Application
of Engle and Granger (1987) cointegration analysis revealed that there is no long-runrelationship between the two variables However, application of the Granger causalitytest revealed that the two variables Granger cause each other in the short run.The Asian financial crisis of 1997 triggered a renewed interest in studying theinteraction between exchange rates and stock prices, mostly in developing countries.Granger et al (2000) concentrated on East-Asian countries of Hong Kong, Indonesia,Japan, South Korea, Malaysia, the Philippines, Singapore, Thailand and Taiwan and usedGranger causality test and Gregory-Hansen cointegration test to analyze the relationshipbetween stock prices and exchange rates They used daily data for the period 1986-1997and showed that exchange rate changes affect stock prices in Japan and Thailand ForTaiwan, the relationship was reversed, that is, stock prices affected exchange rates Theyfound bi-directional relationship between the two variables in Indonesia, South Korea,Malaysia and the Philippines, a finding similar to that of Bahmani-Oskooee andSohrabian (1992) for the USA However, Singapore failed to show any pattern ofrelationship Through Granger causality test it was inferred that exchange rates affectedstock prices in eight of the nine countries Following the same path, Nieh and Lee (2001)used daily data from the period 1993-1996 and explored the dynamic relationshipbetween stock prices and exchange rates in the G-7 countries (Canada, France,Germany, Italy, Japan, UK and USA) Engle-Granger and Johansen maximum likelihoodmethods of cointegration were applied Their results, again, supported the findings ofBahmani-Oskooee and Sohrabian (1992) and reported that there was no long-runrelationship between stock prices and exchange rates in all of the G-7 countries Theresults of VECM estimation suggests that the two financial variables do not havepredictive capabilities for more than two consecutive days and thus there is a short-runsignificant relationship which lasts only for one day for certain G-7 countries
Trang 4Continuing the same line of research, Smyth and Nandha (2003) examined the
relationship between stock prices and exchange rates in four South-Asian countries of
Bangladesh, India, Pakistan and Sri Lanka using daily data from 1995 to 2001 Like
previous studies, using Engle-Granger as well as Johansen’s cointegration techniques,
they were unable to find any long-run equilibrium relationship between the two
variables in any of the four countries Using Granger causality test they also concluded
that exchange rates Granger cause stock prices in India and Sri Lanka but for
Bangladesh and Pakistan they found no evidence of causality running in either
direction During a crisis period the fluctuations in stock prices and exchange rates are
high The Asian financial crisis of 1997 led to series of financial downfall To consider
experiences of other countries in the crisis region, Lean et al (2005) used weekly data
from 1991 to 2002 for Hong Kong, Indonesia, Singapore, Malaysia, South Korea, the
Philippines and Thailand to study the pre- and post-crisis scenario and the effect of
9-11 terrorist attack Japan was used as a control They applied both cointegration and
bivariate causality technique For all of the countries except for the Philippines
and Malaysia, they found no evidence of Granger causality between stock prices and
exchange rates in the period before Asian financial crisis During the crisis period, they
found evidence of causality between the two variables Results show no cointegration
between the variables before or during the Asian crisis of 1997 but after the 9-11
terrorist attack, weaker cointegration relationships between the variables were found
Phylaktis and Ravazzolo (2005) used monthly data from 1980 to 1998 for Hong Kong,
Indonesia, Malaysia, the Philippines, Singapore and Thailand They analyzed the
short- and long-run relationships between exchange rates and stock prices and the
avenues through which exogenous shocks affect these two variables They found that
exchange rates and stock prices are positively related using the method of cointegration
and Granger causality tests US stock price is the causing variable which acts as a
channel that links the exchange rates of the five countries to their stock market indices
Shifting to Europe, Obben and Shakur (2006) analyzed the relationship between
the performance of the stock market and exchange rates in New Zealand using a
cointegrating VAR approach using weekly data from 1999 to 2005 The five exchange
rates were those currencies that are used in the construction of New Zealand’s
trade-weighted index series They concluded that both in the short run and long run there is
bi-directional causality between the five exchange rates and a couple of share price indices
With regards to non-dollar exchange rates, Yau and Nieh (2006) used monthly data of
Japan and Taiwan from 1991 to 2005 to study the relationship among stock prices
of Taiwan and Japan and NTD/Yen exchange rate They applied Granger causality test
and found that there is bi-directional causality between the stock prices of Taiwan and
Japan but there is no significant causal relationship between the NTD/Yen exchange rate
and the stock prices of Japan and Taiwan From the Johansen method of cointegration it
was concluded that there was no long-run relationship among the three variables
However, Yau and Nieh (2009) revisited the issue by testing for cointegration with
threshold effect between the stock prices and the exchange rates in Japan and Taiwan
and the effect of US exchange rate on the financial market of Taiwan Using monthly
data from 1991 to 2008, they found evidence of a long-run equilibrium relationship
between NTD/JPY and the stock prices of Japan and Taiwan There was no short-run
causal relationship between the two countries financial assets which means that
exchange rate and stock price movements do not affect each other significantly in the
short run The results supported the traditional approach that a long-run positive
relationship runs from exchange rates of either Japan or USA to stock prices of Taiwan

Trang 5For seven Asian countries (Hong Kong, Japan, Korea, Malaysia, Singapore, Taiwanand Thailand), Pan et al (2007) applied the methods of Granger causality and Johansencointegration test to examine the linkages between stock prices and exchange ratesusing daily data from 1988 to 1998 They concluded that during the Asian financialcrisis period there is no long-run equilibrium relationship between exchange rates andstock prices For Hong Kong, Japan, Malaysia and Thailand there existed a significantcausal relationship from exchange rates to stock prices before the 1997 Asian financialcrisis and during the financial crisis period they found causal relationship fromexchange rates to stock prices for all countries except for Malaysia.
All studies reviewed above have assumed that the relation between a stock priceand an exchange rate is linear Ismail and Isa (2009) uses Markov Switching VARmodel and assume the two variables to be regime dependent They then studied thenon-linear relationship between exchange rates and stock prices in Malaysia usingmonthly data from 1990 to 2005 The Johansen cointegration test suggested evidence of
no cointegration between the variables Their analysis showed that a non-linear model
is more appropriate to model all the series than the linear model They also foundevidence of common regime switching behavior between the variables Whether linear
or non-linear relationship, it appears that no study finds evidence of long-runrelationship This is also true of Rahman and Uddin (2009) who used monthly datafrom 2003 to 2008 for Bangladesh, India and Pakistan and the method of Johansencointegration and Granger causality test Not only they found evidence of no long-runrelationship between stock prices and exchange rates, they also found no causalrelationship in either direction between the variables The implication is that marketparticipants cannot use information of one market to help to forecast the other market.Considering the experience of Australia, using daily data from 2003 to 2006,Richards et al (2009) studied the relationship between the two variables UsingJohansen cointegration test they showed that that both stock prices and exchange ratesare cointegrated in the long run The method of Granger causality test supported theportfolio balance model which says that changes in stock prices affect changes inexchange rates However, using weekly data from 1989 to 2006, Kutty (2010) wasunable to support cointegration in Mexico, though some evidence of short run Grangercausality was reported Considering the Chinese experience, the dynamic relationshipbetween exchange rates and stock prices was studied by Zhao (2010) using monthlydata from 1991 to 2009 Applying Johansen method of cointegration, the results showed
no stable long-run equilibrium relationship between the real effective exchange rateand the stock price The source and the magnitude of the spillovers were identifiedthrough vector auto-regression and multivariate generalized autoregressive conditionalheteroskedasticity models From the foreign exchange market to the stock market therewas no mean spillover effect but there was bi-directional volatility spillover effects.Further attempt was made by some studies to consider the link between the twovariables by using updated data To that end, Alagidebe et al (2011) used monthly datafrom 1992 to 2005 for Australia, Canada, Japan, Switzerland and UK Again, they found nolong-run relationship between the variables Through Granger causality test it was foundthat in Canada, Switzerland and UK, there is causal linkage from exchange rates to stockprices and in Japan there is causality running from stock prices to exchange rates In thesame line, Harjito and McGowan (2011) used weekly data from 1993 to 2002 for Indonesia,the Philippines, Singapore and Thailand and reported evidence of bi-directional causality
in Thailand and Singapore They also found cointegration between exchange rates andstock prices and cointegration among the stock markets of all four countries
Trang 6By using weekly data from 1999 to 2010 for the countries of Australia, New Zealand,
Japan, Switzerland, USA, UK and Euro Zone, Katechos (2011) examined the
relationship between stock markets and exchange rates in the light of the global equity
market returns The method of maximum likelihood regression with GARCH was
applied and results showed that there is a link between the exchange rates and the
global stock market returns but the characteristics of the currencies determine the sign
of the relationship The value of currencies with higher rates of interest is positively
related to global equity returns and the value of currencies with lower rates of interest
is negatively related to global equity returns Larger is the interest rate differential
more is the explanatory power of the model Sticking to weekly data, Lean et al (2011)
used weekly data from 1990 to 2005 for Hong Kong, Indonesia, Japan, Korea, Malaysia,
the Philippines, Singapore and Thailand and examined the interactions of exchange
rates and stock prices by allowing for structural breaks They applied the methods of
panel Lagrange Multiplier (LM) cointegration, Gregory-Hansen test for cointegration
and Granger causality test to find little evidence of long-run equilibrium relationship
between exchange rates and stock prices Only in Korea, exchange rates and stock
prices were cointegrated The predictive power of the two variables is limited only to
short run, though not for all countries Again, using weekly data during 2000-2008
period, Lee et al (2011) considered the experience of Indonesia, Korea, Malaysia, the
Philippines, Taiwan and Thailand to examine the relationship between the two
variables and the effect on their correlation due to stock market volatility They used
the method of Smooth Transition Conditional Correlation GARCH model to show
that in Indonesia, Korea, Malaysia, Thailand and Taiwan there are significant price
spillovers from stock market to foreign exchange market Stock market volatility does
affect the correlation between the stock and foreign exchange markets For all the
countries except for the Philippines, the correlation becomes higher when the stock
market becomes more volatile
Using rolling regression analysis, Kollias et al (2012) studied the link between the
two variables The advantage of using rolling regression is, with the sample size
remaining same, at a time, the sample period moves forward by one observation
Hence it takes into account of the new information available They used daily data
from 2002 to 2008 for European countries and showed that there is no long-run
relationship between the two variables The direction of causality depends on the
condition of the market There is causality running from exchange rates to stock
prices under normal situation whereas causality might run from stock prices to
exchange rates during crisis situations
Deviating from standard approaches, Tsai (2012) employed quantile regression
approach on monthly data from 1992 to 2009 for Singapore, Thailand, Malaysia, the
Philippines, South Korea and Taiwan The method of quantile regression helps to
study the relationship under different market conditions (“different quantiles of
exchange rates”) Exchange rates and stock prices are negatively related when the
exchange rates are extremely high or low So depending on the conditions of the
market, the relationship can change Considering exchange rates other than against
the US dollar, Wickremasinghe (2012) examined the relationship between stock
prices and the Sri Lankan exchange rates against the Indian rupee, the Japanese yen,
the British pound and the US dollar The results produced no evidence of any
long-run relationship between any of the four exchange rates and stock prices in
Sri Lanka There was only evidence of unidirectional causality running from stock
prices to Sri Lankan exchange rate against US dollar Through variance

Trang 7decomposition analysis it was inferred that most of the variance of the stock price isexplained by Indian rupee[2].
Most of the papers reviewed so far concentrated either on developed or ondeveloping countries However, Buberkoku (2013) considered both developed anddeveloping countries and used monthly data from 1998 to 2008 to study therelationship between stock prices and exchange rates for countries like Australia,Canada, England, Germany, Japan, Singapore, South Korea, Switzerland and Turkey.The methods used were Engle-Granger and Johansen cointegration test and Grangercausality test The results showed that in the long run there is no relationship betweenthe variables in the considered countries, except for Singapore In the short run, stockprices affect exchange rates in Canada, Switzerland and Turkey Causality runs fromexchange rates to stock prices for Singapore and South Korea But for Australia,England, Germany and Japan there was no causal relationship in either directions
To test for sensitivity of the results to data frequency, Tsagkanos and Siriopoulos(2013) used both daily and monthly data from 2008 to 2012 for European Union andUSA to study the relationship between the two variables during the financial crisis of
2008 to 2012 They applied methods of structural non-parametric cointegratingregression, Johansen cointegration test and Granger causality test They found thatmovements in stock prices affect movements in exchange rates in EU in the long runand in USA in the short run Paying special attention to the crisis period, Caporale et al.(2014) focussed on the banking crisis period of 2007-2010 to analyze the connectionsbetween stock prices and exchange rates For Canada, Euro area, Japan, Switzerland,
UK and USA, they used weekly data which were sub-divided into time periods: the crisis period (2003-2007) and the crisis period (2007-2011) Using Bivariate UEDCC-GARCH models they found that in the short run there is unidirectional Grangercausality from stock returns to exchange rate changes in the USA and the UK; in theopposite direction in Canada, and for the Euro area and Switzerland there isbi-directional causality Causality-in-variance from stock returns to exchange ratechanges is found in the USA and for the Euro area and Japan it is in opposite direction,while there is evidence of bi-directional feedback in Switzerland and Canada Duringthe recent financial crisis, dependence between the two variables has increased.Finally, in this bivariate models Yang et al (2014) used daily data from 1997 to
pre-2010 for India, Indonesia, Japan, Korea, Malaysia, the Philippines, Singapore, Taiwanand Thailand to study the relationship between stock returns and exchange rates.They applied Granger causality test in quantiles and they found that during theAsian financial crisis, all the countries except for Thailand there are feedbackrelations between exchange rates and stock prices and in Thailand, stock returns leadexchange rates The causal effects are heterogeneous across different quantiles anddifferent periods and most of the stock and foreign exchange markets are negativelycorrelated
The findings by bivariate studies reviewed above could be biased due to otheromitted variables from the models The next group of studies try to address this issue
by including other macro variables in their model
III Multivariate modelsOver the past recent years due to the trend of the globalization, capital flows amongdifferent international markets has increased which has also led to the increase in closerelationship between the stock markets and the foreign exchange markets Empiricalstudies have also focussed on examining the effect of different macroeconomic
Trang 8variables on stock market The analysis of the effects of different macroeconomic
variables like inflation, GDP, industrial production index, money supply, oil prices,
interest rates, foreign capital, exchange rates, etc are important since they can help
policy makers of an economy to better formulate policies Investors find important and
interesting to see how and which variables cause the stock prices to fluctuate Using an
APM model, Chen et al (1986) examined the effect of different macroeconomic variables
(industrial production, inflation, risk premia, etc.) on the stock returns of the USA and
found that macroeconomic variables have significant effect on expected stock returns
Fama and French (1993) examined four to five factors that affect stock returns and
stock prices
Tian and Ma (2010) studied the relationships among stock prices and macroeconomic
variables like exchange rates, money supply, industrial production and consumer price
index using monthly data from 1995 to 2009 for China They employed the ARDL
method of cointegration Their results show that prior to financial liberalization of 2005,
no cointegration exists between the major foreign exchange rates and the Shanghai
stock price index After the liberalization, cointegration exists Money supply and
exchange rates affect stock prices with positive correlation in China and also previous
month CPI Granger causes stock prices Using Johansen method of cointegration,
Chortareas et al (2011), for countries like Egypt, Kuwait, Oman and Saudi Arabia
examined the role of oil prices as a link between the stock markets and exchange rates
They used monthly data from 1994 to 2006 and their results show that when oil price is
not considered, there is no long run cointegration between exchange rates and stock
prices Inclusion of oil prices show no cointegration between exchange rates and stock
prices when full sample period is considered Before the oil price shock of 1999, no
cointegration among the variables was found After the shock, exchange rates, stock
prices and oil prices are cointegrated in Egypt, Oman and Saudi Arabia But for
Kuwait, there is long-run relationship only between stock prices and oil prices Real
exchange rates are positively related to stock prices in Egypt and Oman and in
Saudi Arabia they are negatively related Oil prices have long-run positive effect on
stock prices The model employed by Liu and Tu (2011) included exchange rate and
foreign capital as determinants of stock prices They used daily data from 2001 to 2007
from Taiwan to study the relationships among the variables and to analyze whether in
these markets the properties of asymmetric volatility switching and mean-reverting
exists or not They found that the movements of the exchange rate and the stock price
index are affected by overbuying and overselling rates of foreign capital All of the
three conditional means exhibit asymmetric mean-reverting behavior (negative returns
reverting quicker than positive returns) The volatility of the three markets exhibited
GARCH effects
The model employed by Parsva and Lean (2011) included like interest rates, inflation
rates and oil prices as main determinants of stock prices in Egypt, Iran, Jordan, Kuwait,
Oman and Saudi Arabia Using monthly data from 2004 to 2010 they estimated their
model using Johansen method of cointegration and Granger causality test They found
that in the long run, all variables are cointegrated Both in short run and long run there is
bi-directional causality between stock prices and exchange rates for Egypt, Iran and
Oman before the crisis In Kuwait causality runs from exchange rates to stock prices in
the short run Comparing the pre- and post-crisis periods, there was not much distinction
in the behavior of exchange rates and stock returns Oil price was also included in a
model by Basher et al (2012) who used monthly global data from 1988 to 2008 to examine
the relationship among stock prices in emerging markets Additionally, they included

Stock prices and exchange
rates
Trang 9global real economic activity as one of the variable which affects oil prices Using astructural VAR model and through the analysis of impulse response function they foundthat positive shock to oil prices decreases emerging markets stock prices and US dollarexchange rates in the short run Exchange rates respond to changes in oil prices in theshort run, a positive shock to oil prices leads to decrease in trade-weighted exchangerates Oil price decreases with increase in oil production but a positive shock to realeconomic activity increases the price of oil Along similar lines, Eita (2012) employedJohansen’s method and quarterly data from 1998 to 2009 for Namibia to examine thedeterminants of stock prices The results showed that stock prices are affected byeconomic activity, exchange rates, inflation, interest rates and money supply Stockprices increase with increase in economic activity and money supply and stock pricesdecrease with increase in inflation and interest rates Exchange rates, GDP, moneysupply and inflation move stock market away from equilibrium Similarly, Inegbedion(2012) considers the experience of Nigeria by using data from 2001 to 2009 By applyingCochran-Orcutt Autoregressive Model, the results show that exchange rates and stockprices are negatively related The relationship of stock prices with interest rates andinflation, respectively are not significant But the joint effect of all the variables on stockprices is significant[3].
Foreign reserves and interest rates were added as additional variables into therelation between stock price and exchange rate to explore the effects of portfolioadjustment by Lin (2012) Using monthly data during 1986-2010 and the ARDLapproach, the model was estimated for Asian emerging countries of India, Indonesia,Korea, Philippines, Taiwan and Thailand During crises periods, in terms of long runcointegration and short-run causality, the co-movement between exchange rates andstock prices became stronger Spillover effect was mostly from stock price shocks toexchange rates Further analysis showed that the co-movement is generally driven bycapital account balance than the trade balance Separately, Pakistan was the country ofconcern by Aslam and Ramzan (2013) who studies the effects of the real effectiveexchange rate index, CPI, per capita income and discount rate on the stock prices.Applying NLS and ARMA techniques revealed that while discount rates and inflationnegatively affected Karachi stock price index, per capita income and real effectiveexchange rate index affected positively Discount rate impacted stock index the most.This study helps to understand how effectively a country can control itsmacroeconomic variables for better performance of the stock market In the samevein, commodity prices are introduced into the relation between the exchange rate andstock market by Groenewold and Paterson (2013) who employed monthly data during1979-2010 from Australia Their results showed that when commodity prices are notconsidered, there is no cointegration between exchange rates and stock prices With theinclusion of commodity prices, all the three variables are cointegrated in the long run.When only exchange rates and stock prices are considered, there is no causalitybetween them in either direction In the short run, exchange rates affect commodityprices and commodity prices in turn affect stock prices
Different macro variables in Pakistan were also considered by Khan et al (2013) whoused monthly data from 1998 to 2008 The macroeconomic variables considered weremarket returns, CPI, risk-free rate of return, industrial production and M2 The resultsshowed that both stock prices and exchange rates affect each other in the short run butthere is no long run association between the variables In the long run, market returnand risk-free return are not related to stock prices but there is some association ofindustrial production and stock prices There exists both short run and long-run
Trang 10relationship between stock prices and inflation and money supply Boonyanam (2014)
explored the relationship between different monetary variables with stock prices
The monetary variables included were nominal bilateral exchange rate in terms of Baht
per US dollar, CPI, narrow money and 14 days repurchase rate and the methods used
were multivariate cointegration, VECM and variance decomposition analysis Monthly
data from 1999 to 2012 was used for Thailand and the results show evidence of
long-run relationship between stock prices and monetary variables In the short run,
narrow money and interest rate affect stock prices There is one way causality from
exchange rates to stock prices and from interest rates to stock prices There was also
positive relationship between CPI and stock price
Rather than using stock prices, Moore and Wang (2014) examines the source of the
relationship between stock return differentials and real exchange rates using monthly
data for Australia, Canada, Indonesia, Japan, the Philippines, Malaysia, Singapore,
South Korea, Thailand and the UK At the first stage, the dynamic conditional
correlation (DCC) is derived between the two variables and then the derived DCC is
used to regress on the interest rate differentials and the trade balance With the help of
bivariate GARCH model with DCC they found that there is a negative relationship
between the relative stock prices and real exchange rates There exists time-varying
correlation between stock return differentials and real exchange rate changes The US
stock market influences the foreign exchange market and local stock market Trade
balance is the major determinant of the dynamic correlation for Asian market and
interest rate differential is the key factor for developed countries For the countries
where capital mobility is low, economic integration acts as the cause of the linkage and
thus it supports the flow-orientated model But where capital mobility is more, financial
integration acts as the cause of the linkage which in turn favors the stock-oriented
model Finally, the case of Turkey is considered by Tuncer and Turaboglu (2014) who
used quarterly data from 1990 to 2008 to examine the short run and long-run
relationships between stock prices and GDP, treasury bills rates and exchange rates
They employed the method of Johansen test for cointegration to study the long-run
relationship and found evidence of long-run relationship between stock prices and the
other variables In the short run, stock prices and real effective exchange rate affect
GDP but there is no causality relationship from treasury bills to GDP There is
causality from real effective exchange rates to stock prices All the variables do not
affect exchange rates in the short run hence exchange rate is comparatively an
exogenous variable
In sum, the literature on the relation between stock prices and exchange rate is vast
From the review of more recent studies it is clear that the link between the two
variables is dependent on the data frequency and period chosen, the countries studied,
and other macro variables, etc But in general most of the papers concluded that in the
short run, stock prices and exchange rates are related but there is no relationship
between them in the long run Other macroeconomic variables like, CPI (inflation rate),
interest rates, discount rates, oil prices, money supply, industrial production, GDP and
foreign capital also are found to affect stock prices Table I provides the main features
of each study reviewed
IV A new direction for future research
The models reviewed in the previous section and all studies listed in Table I have one
common feature They have all assumed that the effects of exchange rate changes on
