Financial Risk & Network Theory

In collaboration with Journal of Network Theory in Finance

Financial institutions and markets are highly interconnected, but literature has only recently begun to emerge that maps these interconnections and assesses their impact on financial risks and returns. The conference "Financial Risk and Network Theory 2016" organised in collaboration with the new Journal of Network Theory in Finance (JNTF), continues the successful conferences in 2014 and 2015 in generating new collaborations in this emerging multidisciplinary field.

The Financial Network Visualisation Prize

We are keen to promote and encourage visualisation techniques as a way of helping people understand complex patterns of data in the comprehension of financial networks.

At last year's conference we were very impressed by the quality and range of visualisation techniques applied in the presentation of networks, and examples from the presentations were collected in a showcase of techniques; in 2015, we awarded the first Cambridge Centre for Risk Studies Prize for Financial Network Visualisation, for the best network visualisation presented at the Conference on 9 September.

View examples from the presentation showcase

2015's winning image was presented by keynote speaker Mark Flood in his talk On Counter Party Networks, featuring the holding company hierarchy over time for Wells Fargo BHC.

All the visualisations presented by the participants will be entered into the competition. The winning image will be reproduced as a large-scale framed poster for the presenter and their institution.

Research areas

Topics include but are not limited to the following:

  • Empirical network analysis that enables better understanding of financial flows, exposures and markets
  • Modelling and simulation techniques for measuring interdependent financial risks
  • New metrics and techniques for identifying central, vulnerable or systemically important institutions and markets in financial networks and informs regulatory strategies for improving financial stability
  • Network modelling of time-series data for financial risk management, asset allocation and portfolio management
  • Social network analysis (SNA) in finance, e.g. for making credit and investment decisions
  • Applied network visualisation techniques that improve the communication of financial risks and rewards
  • Analysis of counterparties and their risk exposure from interconnectivity with the financial system
