Nonlinear effect of Islamic financing on economic stability: A Case of equity and debt financing

Abstract

The main purpose of this study is to differentiate between the effects of two major categories of financing of Islamic banks on the economic stability of the selected countries. This study determines the nonlinear effect of equity-based and debt-based financing of Islamic banks to assess how the stability of the economy can be achieved. This study acquires the data on Islamic banking product-wise financing at a national level from the Islamic Financial Service Board (IFSB), and the data on industrial production index is selected from International Financial Statistics for selected countries. The sample size comprises of all the countries included in the IFSB. The data ranges from 2014Q1 to 2019Q4. The economic stability is estimated using the GARCH volatility approach, and the nonlinear ARDL model is used to determine the causal effect of Islamic banking product wise financing. This study clarifies the empirical relationship between Islamic banking equity-based financing and debt-based financing and whether macroeconomic stability is linear or quadratic in terms of the marginal effect of financing, which helps policymakers to constitute strategies for expanding the size of Islamic banking financing. The results identified the inverted U-shaped effect of equity-based financing types on output instability. At the same time, both financing types are not causing price instability. The outcomes are instruments for the central bank to optimize the Islamic banking financing structure to achieve the goal of product-wise financing of economic stability.
