Context: Aftermath of the financial crisis

Financial System

understood as a network

Systemic risk:“too connected to fail”

Stress and increase of regulation

Extended mandate(s) to collect data

Need to process and analyze this

data

New paradigm of

data collection and analysis

Questions:

• How to make sense of data?

Questions:

• How to make data analysis actually operative in supervision and regulation?
