A framework to minimize systemic indebtedness : a financialisation theoretical perspective

Abstract

The purpose of this study is to develop an indebtedness framework that explains the effects of financialisation and household indebtedness on economic development. For this purpose, the study empirically examines annual South African data covering the years 1990-2017 to look at the effect of financialisation before and after the 2007/08 financial crisis. South Africa adopted an inflation targeting monetary policy regime in the 1990s before the global economic crisis in response to the global financial crisis of 2007-08. Examining data from 1990-2017 made it possible to look at the effects of financial deregulation policies that were introduced post the 2007-08 financial meltdown.

The study addressed three objectives. The first objective sought to establish the extent of financialisation in the South African economy pre and post the 2008 financial crisis. To achieve this objective, annual time series data from 1990-2017 on financialisation variables was split into two, before and after the financial crisis. Graphical presentations of the four financialisation variables (financial deregulation, foreign financial inflows, asset price volatility, and shift to market-based finance) showed that there was a difference in financialisation before and after the 2008 financial crisis. Analysis of variance showed that there is a statistically significant difference between the foreign financial inflows’ series before and after the financial meltdown of 2008 (t-test value -6.527, p ≤ 0.0001). (1990-2008). The findings also showed that there was no statistically significant difference between asset price volatility before and after the financial meltdown of 2008. Interestingly, there is a statistically significant difference between stock market value traded in the period from 1990-2008 and 20092017 after the financial crisis (t = -4.295, p ≤0.001).

The second objective sought to examine the causal direction between financialisation and household indebtedness. Contrary to a priori expectations, the findings showed that financial deregulation, foreign financial inflows and shift to market-based finance do not Granger cause indebtedness. However, the findings showed that the null hypothesis that asset price does not Granger cause household indebtedness was rejected. This implies that there is a causal direction between asset price volatility and household indebtedness

Lastly, the third objective of this study was to explain the effects of financialisation and indebtedness on economic development to inform the indebtedness framework that this study set out to develop. Using annual data for the period of 1990 to 2017, the third objective was addressed by examining the effect of household indebtedness and financialisation on economic development. These effects were tested using OLS regression and error correction modelling technique (ECM) for each of the four financialisation variable: (1) financial deregulation measured using the financial reform index; (2) foreign financial inflows measured using stock of foreign liabilities as percentage of GDP; (3) asset price volatility; and (4) shift to market-based finance, measured using stock market value traded as percentage of GDP.

The findings showed that foreign financial inflows and asset price index when regressed with household indebtedness showed a statistically significant effect on economic development in a long-run model. The indebtedness framework was duly presented showing that economic development is likely to be negatively and strongly affected by financialisation as experienced in asset price volatility and foreign financial inflows.
