Shadow banking is the creation or transfer – by banks and non-bank intermediaries – of bank-like risks outside the banking system. In Italy the shadow banking system is fully regulated, mostly following the principle of same business-same rules or ‘bank-equivalent regulation’. After an overview of the topic, we describe the Italian shadow banking system and the related regulatory and supervisory framework in place before the financial crisis and the subsequent enhancements. A quantitative representation of Italian shadow banking is also provided. The paper argues that through a wide and consistent regulatory perimeter, based on the principle of ‘bank-equivalent regulation’, it is possible to setup a well-balanced prudential framework, where both bank and non-bank regulation contribute to reducing systemic risks and regulatory arbitrage.
