Fedwire Interbank Payment Network (Fall 2001) was one of the first network views into any financial system.""Of a total of around 8000 banks, the 66 banks shown comprise 75% of total value. Of these, 25 banks completely connected""The chart was subsequently used e.g. in congressional hearings to showcase the type of information that should be collected by financial institutions after the financial crisis. ""The research is cited in ~300 academic publications."

Journal
New Journal ‘Network Theory in Finance’ is launched in March 31, 2015""Editor in Chief: Kimmo Soramäki""Editorial Board: Andrew Haldane, Franklin Allen, Ignazio Angeloni, etc."""“Journal of Network Theory in Finance is an interdisciplinary journal publishing rigorous and practitioner-focused research on the application of network theory in finance. The journal connects academia, regulators and practitioners in solving important issues around financial risk” !"2nd Annual conference on 9 September 2015 at the University of Cambridge.
The FNA Software consists of FNA Platform and FNA Apps. "FNA Platform is the server side workhorse for analysis, simulation and visualization of financial networks used by all FNA Apps.
FNA Software FNA Apps master particular uses cases with an interactive user experience.

Network MapsBig data problem: Three billion messages exchanged among banks in 231 countries. We focus on aggregated links among countries. "Analysis and visualization a challenge. We don’t want to show much information (as below).
Evolution of Links
Of the 1054 links gained until 2007, in 74% one (or both) were rated as medium or low on the United Nations Human Development Index.
Of the 990 links lost after 2007, 80% involved at least one country listed as an offshore financial center.
Total Messages
The number of messages is 5.5% lower (post-crisis than they would have been had the pre-crisis trend continued unabated throughout the entire period.
The cost of financial crisis $5tr?
Communities
Are there meaningful subgroups among the countries? "Can we group the countries so that messages are sent mostly within groups? "Modularity - measure of concentration of links within communities vs. between communities.

The research was the first to tap into this large database of payments flows. "We looked at a broad array of topics with the question: How could the data be useful, and to whom? "Information perhaps most value for senior management and strategy development. "Due to short history of data, predictive models were weak.
Summing up
Other Insights from Payment Data
Identifying Supply Chains
Supply Chain data can be identified from payment data. """""Supply chain information can be used e.g. for: - better credit scoring models - allocation of credit lines - insurance applications (casualy, business disruption - etc. "
Nowcasting GDP - the Swift Index
Identifying interbank loansCentral banks identify information for financial stability analysis from interbank payment systems using the ‘Furfine’ Algorithm.

Payments are Big Data""Do you have IT systems to readily access and analyze payments data? ""What kind of insights would be useful to find from the data? e.g control risks/fraud, find new business opportunities, identify key clients? ""Can you think of any information products that could be developed with your data?
FNA Platform Over a decade in making and with a wider selection of financial network algorithms than any other software, the FNA Platform offers a comprehensive end-to-end solution for advanced analysis and visualizations of financial networks. "FNA Platform is the backbone of all FNA Apps and available as a cloud-based solution with a RESTful API, as an enterprise installation, as a Desktop software and as a Java library.
Cutting-edge analytics Calculate hundreds of graph metrics, perform cluster analysis and carry out predictive stress tests and simulations. "Complete documentation with over 500 pages of manuals describing the platform’s functionality with examples, tutorials and real-life applications. "End-to-end automation Develop scripts for fully automated and regular analytics or use FNA REST API from external applications. "Easy integration tap to data most common online data sources and vendors directly, or from local databases.
