Financialization and unconventional monetary policy: a financial-network analysis

Over the last decades, both advanced and emerging economies have experienced the emergence of the phenomenon known as financialization, that, until some time ago, was generally considered beneficial for the economy. The 2007-2008 crisis and the severe post-crisis recession called into question the assumptions underlying the positive perception of the role played by financialization in the economy. In particular, the effects of financialization on financial stability and inequality are now widely recognized. A recent debate focused on the effectiveness of unconventional monetary policy tools in transferring their effects on the financial sphere to the economic sphere (e.g., via stimulating the transmission of resources from the banking system to the real economy). Among these unconventional policy measures, Quantitative Easing (QE) has been recently implemented by the European Central Bank (ECB). In this context, two questions deserve more attention in the literature. First, to what extent QE may generate net flows of additional resources to the real economy. Second, to what extent QE may also alter the pattern of intra-financial exposures among financial actors and what are the implications in terms of financialization. Here, we address these two questions by mapping and analyzing the euro area multilayer macro-network of financial exposures among institutional sectors across financial instruments (i.e., loans, bonds, equity, and insurance and pension schemes) and we illustrate our approach on recently available data. We then test the effect of the implementation of ECB's QE on some novel measures of financialization that we derive from the time evolution of the financial linkages in the multilayer macro-network of the euro area.
