Causality Analysis of South Africa Reserve Bank’s Monetary Policy Statements and Communication

This paper inspects whether the South Africa Reserve Bank’s (SARB) Monetary Policy Committee (MPC) statements trigger have a causality with newspaper reports from the Mail and Guardian between 2010 and 2021. The study examines whether SARB’s post MPC statements’ readability is reciprocated in the subsequent Mail and Guardian newspaper articles. Using the Flesch Reading Ease Score and Flesch-Kincaid Grade Level score as the methodology, there is a systematic unpacking of both SARB’s MPC statements and newspaper reports from the Mail and Guardian which yield a dataset which is subsequently used to create a computation. This computation is then used to examine whether SARB’s MPC statements Granger cause the subsequent Mail and Guardian newspaper articles. Resultantly, the results show that there is no Granger causality between the SARB’s MPC statements and the Mail and Guardian’s Flesch Reading Ease Score and Flesch-Kincaid Grade Level score.
