Cointegration Analysis Between Stock Exchange and TL/FX Saving Deposits, Gold, Housing Markets in Turkey

Abstract

The paper asks whether the return of Borsa Istanbul100 index has long term relations with U.S. Dollar to Turkish Lira (TL) exchange rate, London Bullion Market Association (LMBA) gold fixing price, interest rate on TL saving deposit, and real house price index over the period of 2000:01-2014:07 in Turkey. We first test stationary of time series through Augmented Dickey Fuller, Phillips-Perron, Zivot-Andrews, and Lee-Strazicich unit root tests. Then, we perform Johansen cointegration test and multiple structural breaks cointegration test of Maki (2012). Johansen cointegration test suggests that there is a long term relationship among the variables, but Maki cointegration estimation do not provide evidence for the existence of cointegration. According to the latter result, we may argue that TL/FX saving deposits, gold, and housing markets in Turkey, having probably different investment dynamics and investor profile, may not integrate or compete with stock market under the impacts of structural breaks. This outcome may also imply that the policies on the development of stock market and contributions of stock market to the growth may have some structural limitations.
