About this book

This book presents empirical evidence that supports and facilitates a practical, integrated approach to how bank regulatory and selected macro-prudential tools interact with monetary policy to achieve price and financial stability. The empirical results contained in various chapters accompany in-depth historical analysis and counterfactual scenarios that enable proper policy evaluation and the interaction of bank regulatory, macro-prudential and monetary policy tools in South Africa. The presented evidence also identifies financial asset boom and bust episodes and the associated costly output losses. In addition, the authors explore the amplification of credit dynamics by commodity prices and sector credit re-allocation due to capital inflows shocks. The book’s empirical analysis uses a wide range of statistical and econometric approaches on granular data and economic variables to derive policy implications and recommendations. This in-depth quantitative analysis includes determining inverse transmission of global liquidity, as well as the effects of capital flows, lending-rate margins, financial regulatory uncertainty, the National Credit Act, bank capital-adequacy ratios, bank loan loss provisions, loan-to-value ratios and repayment-to-income ratios on the macro-economy.

1. Introduction
Abstract
The United States mortgages subprime crisis is acknowledged as the start of what became the global financial crisis in 2007. This period was followed by global recession and the Euro Area sovereign debt crisis. South Africa went into a brief but sharp recession in 2009. The subsequent period was characterized by elevated economic uncertainties and fragile recovery. In response to the financial crisis, central banks in advanced economies lowered policy rates to almost zero percent and embarked on various unconventional monetary policy interventions, injecting liquidity in global financial markets. The central assumption underlying this approach by central banks was not solely to normalize the functioning of interbank markets but to improve global output and demand conditions. The transmission of quantitive easing (QE) was supposed to stimulate economic growth, investment and expenditure, primarily by encouraging risk-taking by firms and households via the so called “real risk-taking.”
