Who drives whom - sukuk or bond? A new evidence from granger causality and wavelet approach

Sukuk is a highly appealing alternative instrument of conventional bond in the financial market over the last two decades. To a certain extent, the market players assume sukuk as the same as bond. However, sukuk has its own fundamental asset backed principles, whereas bond is backed by debt. The objective of the study is to examine the Granger-causality and lead-lag relationship between sukuk and bond by using the data of the Malaysian Government securities return for both conventional and Islamic instruments. The data for every working day of 7 years covering the period from January 31, 2007 to December 31, 2013 were collected from Bloomberg database. The yield returns of both securities have been plotted for each six months of a year. This study applied both Granger-causality and dynamic co-movement techniques such as, continuous wavelet transforms (CWT) coherence for analyzing the temporal evolution of the frequency content of both securities by decomposing each period into different time scales. The empirical findings of the paper reveal that with a bit of exception, there is a causal relationship between sukuk securities and conventional bonds for a given period of time. For robustness, this study applied the wavelet coherence approach and found that bond is led by sukuk in the long term investment horizon rather than in the short term. Our findings relating to the lead-lag relationship between sukuk and bonds have important implications in terms of policy regulations and investment management. Future research and market practices could reinvestigate the differences between these two securities across different markets and types
