Sukuk and monetary policy transmission in Indonesia: the role of asset price and exchange rate channels

Purpose The purpose of this study is to empirically analyze the role of sukuk in the monetary policy transmission mechanism through the asset price and exchange rate channels in the Indonesian economy. Design/methodology/approach Using the monthly data from January 2003 to November 2017, this study uses a multivariate vector error correction model causality framework. To examine the role of sukuk in the monetary policy transmission mechanism through the asset price channel, this study uses the variables of consumption, inflation, interest rates, economic growth and the composite stock price index. Meanwhile, to examine the role of sukuk in the monetary policy transmission mechanism through the exchange rate channel, this study used variables of inflation, interest rates, economic growth, foreign investment and exchange rate. Findings This study documented that sukuk has no causal relationship with inflation through asset price and exchange rate channels. Nevertheless, sukuk has a bidirectional causal relationship with economic growth through asset price and exchange rate channels. Sukuk is also documented to have a causal relationship with monetary policy variables of interest rate and stock prices through asset price and exchange rate channels. Finally, a unidirectional causality is recorded running from the exchange rate to sukuk in the exchange rate channel. Research limitations/implications The finding of independence of the sukuk market from interest rates provides evidence that the trading of the sukuk in Indonesia has been in harmony with the Islamic tenets. Practical implications The relevant Indonesian authorities need to enhance both domestic and global sukuk markets as part of efforts to promote the sustainability of Islamic capital market development in Indonesia. Originality/value To the best of the authors’ knowledge, this study is among the first attempts to empirically investigate the role of sukuk in monetary policy transmission through asset price and exchange rate channels in the context of the Indonesian economy.
