Centre for Digital Finance (CDF)

Background

The rapid pace of technological innovation over the last two decades has changed the way we do business and finance. The Centre for Digital Finance (CDF) brings together researchers to investigate this new electronic world. This includes research in electronic financial markets and banking, which are by far the largest and most important electronic marketplaces in the world today. It also includes the business and financial aspects of technology research. The Centre’s members come from a variety of academic disciplines and it aims to foster a deeper understanding and awareness of the complex inter-relationship between business and technology through research, consultancy and education.

.

The Centre was established in 2014 and has developed a track record of regular publication in international journals and successful research grant applications. In addition, group members regularly disseminate their research via seminars, workshops and international conferences. We actively seek joint activities with other international research centres and institutions.

Vision 

The Centre for Digital Finance is to become a leading hub for innovative, collaborative and multidisciplinary research that transforms the existing understanding of challenges of technological innovations in finance and provides solutions for contemporary business problems.

Helping to Mend Britain’s Broken Pensions and Benefits System

22 May 2017
Professor Frank McGroarty and Dr Andrew Urquhart of the Centre for Digital Finance have been working with the pensions and benefits industry to help resolve well-documented problems in the sector. They organised and hosted a specialist focus group of influential representatives of public and private sector organisations to explore the important issue of “Interoperability”. This event was held at the Digital Catapult’s office in London on 16 May 2017 and was considered a great success by all participants.

In 2012, the Royal Society of Arts (RSA) published a report titled ‘Seeing Through British Pensions: How to Increase Cost Transparency in UK Pension Schemes’ which estimated the annualised average fee charged by UK pension providers to be “…. 1.7%, and [this] had been rising over previous years, and that trading costs were [an additional] 1.4%, making a[n average annual] total charge of 3.1%. This was for an equity fund but if such a charge was applied over the 25-year life of a pension fund, more than half the poten­tial pension benefit would disappear”. This report prompted the then Pensions Minister, Steve Webb, to impose a mandatory cap of 0.75% on charges for all new pension savings from April 2014 onwards. However, an Office of Fair Trading report of December 2014 showed that older pension products continued to be subjected to much higher ongoing servicing costs.

There are two roots to the problem of ongoing high pension charges. The first, as the RSA report highlights, is the lack of Transparency – i.e. the customers cannot see the costs clearly and so do not seek to challenge them. The second is lack of Interoperability – i.e. the systems of the different pension providers’ platforms do not communicate to each other and so even if a customer does wish to move assets from one pension scheme to another, it is difficult and costly to do so. These two factors together stifle competition, with the result that prudent and responsible pension savers in the UK face much lower pots of capital at retirement than they expect. Professor McGroarty and Dr Urquhart perceived an opportunity to do some impactful research, which could help to find a solution to these market inefficiencies.

Initial discussions with the industry suggested that there was a potential research project based on the Blockchain, which is the technology that underlies Bitcoin, about which Dr Urquhart has published, and in which both researchers have a keen interest. However, further discussions made clear that this idea was too radical for the current state of the industry. At present, the distribution of pension products in the UK is via platforms (siloes) dominated by the large insurance companies. The distribution process is highly intermediated and insufficiently automated, which means that product administration costs and product transfer costs are high. At the heart of the issue is that there are no common open standards to which pension platforms must adhere, which is the reason for the lack of interoperability in the sector. Agreeing to and complying with common standards would permit interoperability, which would be the first steps towards increasing automation and getting administration costs down. While the industry has known this for years, it has not done anything to bring about common standards. No player in the industry wants to take a lead because that would require a unilateral investment of time and resources into something that would produce no competitive advantage. Moreover, competitors would view any unilaterally introduced interoperability solution with suspicion. Furthermore, it is arguable that pension providers are satisfied with the prevailing high-fee status quo. Correspondingly, the various government stakeholders have historically taken the view that the industry has abundant capital and therefore is not a worthy candidate to receive any public resources.

Discussions with individual stakeholders led Professor McGroarty and Dr Urquhart to the conclusion that greater engagement was necessary from all key stakeholders, but particularly from government stakeholders who need to form an alternative vision to the status quo and provide leadership on this important public welfare issue. As academics who were independent of the industry, Professor McGroarty and Dr Urquhart believed they could help to mediate a solution. The Centre for Digital Finance planned, organised and hosted an invitation-only specialist focus group of pensions and benefits industry stakeholders at the offices of the Digital Catapult in London on 16 May 2017. The event was attended by senior representatives from: Department of Work and Pensions, Department of Business, Energy and Industrial Strategy, British Standards Institute, UK Accreditation Service, All Party Parliamentary Group on Fintech, Competition and Markets Authority, Digital Catapult, Government Digital Service, Cabinet Office, Pensions Regulator, Pensions Administration Standards Association, Transparency Task Force and SBC Systems (UK) Ltd.

A poll of the attendees at the close of the event showed that all unanimously agreed that they had gained a deeper understanding of the importance of Interoperability in the pensions and benefits industry because of the Centre for Digital Finance’s event. In addition, the participants concluded that a government-led steering group should be formed to take the issue of interoperability standards forward. A number of the attendees have already committed to serve on this steering group. This was the best possible outcome from this meeting. Professor McGroarty and Dr Urquhart expect this steering group to succeed in introducing a set of common open standards for interoperability among pensions and benefits platforms in the near future and that this would provide the setting for the Blockchain research project they originally proposed.

A second PhD student from CCFBA gains prestigious internship at the IMF

25 April 2017

Over the past twelve years, five PhD students from the Centre for Computational Finance and Business Analytics (CCFBA) and Southampton Business School have been successful in achieving internships at the International Monetary Fund (IMF). The five PhD students are Klaus Schaeck (2005), Sarah Odesanmi Sanya (2008), Mohammed Amidu (2010), Mohamed Bakoush (2016) and Hana Bawazir (2017).

What they all have in common is that their PhD supervisor is or was Professor Simon Wolfe. This success places the University alongside Oxford, Cambridge and the LSE in terms of PhD students being offered internships.

Interns return to their studies with an enlightened vigour after experiencing three months working at the Fund. In addition, the experience prepares students for very high achievement in their future careers. Prof Klaus Schaeck (Bristol University) is an expert on banking, Sarah Sanya is a fulltime Economist at the IMF, and Mohammed Amidu is head of the Department of Accounting and Finance (University of Ghana).

Both Mohamed Bakoush and Hana Bawazir are currently PhD students in CCFBA, Mohamed is working on financial stability whereas Hana is researching bank liquidity.

Chartered Association of Business Schools Conference

03 April 2017

Professor Frank McGroarty attended the Chartered Association of Business Schools conference on 28 and 29 March 2017. In an exchange with Jonas Nystrom (Head of Science and Innovation, HM Treasury) Frank extracted an admission that funding for Academic Research, which had previously been provided by the European Union, has not been ring-fenced by the government from other post-Brexit funding. In addition. Frank asked Paul Mason of Innovate UK why the Financial Services industry was poorly supported by public research funding - citing his recent experience with the Digital Catapult who pulled back from a research project on pensions that they had previously committed to being involved in. He made the point that not all entities in the financial services world are well-endowed banks and that there is need for publicly funded research on matters that affect public welfare, e.g. pensions servicing costs. Paul suggested that there may be a softening in the position of Innovate UK on this matter and that Frank should seek to re-kindle his conversation about pensions with the Digital Catapult

Research Projects

We conduct high-quality research to gain a greater understanding of financial market complexity, electronic financial markets and banking and quantitative modelling. Current projects include:

  • Professor Frank McGroarty's successful bid to the European Union’s Seventh Framework (F7) Programme to fund IoT Lab, a European project that aims to researching the potential of crowdsourcing to extend IoT testbed infrastructure for multidisciplinary experiments with more end-user interactions. The €3.35m grant is being used to provide an accurate economic and business opportunity analysis for the IoT testbed, as well as cost and efficiency monitoring tools. It will then compare the various models and explore innovative business models and an opportunities analysis. Finally, the project will analyse and optimise the economic dimension of the project.
  • A project led by Professor Frank McGroarty and Dr Sha Liu, funded by a Web Science Institute Research Collaboration Stimulus Fund Grant of £15,000, and a further £15,000 from industry partner Channel Creator. The funds are being used to acquire a subscription to a data service provided by Visible Technologies, a brand leader in aggregation, storage and analytics of social media data. The immediate objective is to prepare a more substantial and complete research proposal on 'measuring financial sentiment in social media', which provides a unique opportunity to apply web science research in building the tools through which the finance industry will view the read-write web.
