Retail banks and big data

A report from the Economist Intelligence Unit Retail banks and big data: Big data as the key to better risk management Retail banks and big data: Risk and compliance executives weigh in Big data as the key to better risk management Big data as the key to better risk management The business of banking depends on evaluating risks and then acting on those insights In theory, more information should yield better risk assessments, which is why big data and its associated tools couldn’t have arrived at a better time The ability to harness larger and more diverse data pools in support of business decision-makers holds the promise of both reducing losses by managing risks and increasing revenue by highlighting business opportunities Successfully managing risks today requires that bankers identify, access and analyse trusted data and share their results across the bank The growth of risk As recent headlines bear out, risks increase with complexity, and complexity has grown across every dimension of the banking industry Banking has become more concentrated, which means that a handful of giant institutions must coordinate a diverse array of products, processes, technologies, organisational structures and legal contracts Financial innovation leads to new instruments and specialties Markets are more interconnected and © The Economist Intelligence Unit Limited 2014 information traverses those connections more rapidly As a result, when things go wrong, volatility can switch markets from tranquil to turbulent almost instantly, leading to “volatility clustering” that can result in liquidity crises like those seen in the 2007-2009 financial crisis or the 2001 bursting of the dotcom bubble Clearly, the landscape of banking risks is vast “We have identified 13 different types of systemic risk: cyber-risk; high-frequency trading risk; counterparty risk; collateral risk; liquidity risk; and the list goes on,” says Mike Leibrock, vicepresident of systemic risk at the Depository Trust Clearing Corporation (DTCC), which provides clearing and settlement services to large banks “And there is an entire category of interconnectedness risks, which arise from linkages among a handful of key banks for clearance and settlement activities.” As regulators—and therefore also the institutions that they regulate—focus as never before on identifying, measuring, and managing emerging risks across the financial system, data management practices are also changing Retail banks and big data: Risk and compliance executives weigh in Big data as the key to better

Intelligence Unit survey, July, 2014 The promise and potential of big data Banks are experts in manipulating the rows and columns of numbers captured from past transactions and stored in vast data warehouses On a daily or even intra-day basis, banks package these facts in the form of reports for credit or finance officers to review for trends and outliers Big data is different It is vast in scope, varied in form and instantaneous in velocity, encompassing data from mobile devices, social media applications and website visits as well as information from third-party providers of credit, spending, auto and legal data It promises to reveal hidden consumer behaviors that may not be immediately apparent even to those with highly sophisticated knowledge and experience Big data potentially allows banks to measure and manage risk at an individual customer level, as well as at a product or portfolio level, and to be much more precise in credit approvals and pricing decisions To learn more about the intersection between big data and risk management at banks, the Economist Intelligence Unit (EIU) surveyed 208 risk management and compliance executives at retail banks (29%), commercial banks (43%) and investment banks (28%) in 55 countries on six continents The results demonstrate that growing numbers of bankers are embracing the analysis and sharing of big data, but that they still face challenges in applying the results to delivering superior risk management performance—especially around liquidity and credit risk © The Economist Intelligence Unit Limited 2014 The survey asked executives to rate their own institution’s performance in controlling and mitigating risk Those that rated their institution above average were also more likely to use: l basic big data tools to integrate, manipulate and access structured and unstructured data (35% for the above-average risk managers versus 7% of those rated average or below) l more advanced big data tools such as predictive analytics and visualisation (33% versus 8%) In other words, banks that perform better are more likely to use a variety of different methodologies, including both basic and advanced analytics, to understand and manage their risks Moreover, they’re more likely to bring large amounts of data to bear on risk management problems Investments in big data to support risk management In addition to the four regions, survey respondents came from three types of institutions: 43% from commercial banks and the rest divided evenly between retail and investment banks All three are more concerned about liquidity and credit risk than other types of risk At the same time, the importance they assign to different types of risk varies by industry and region l Retail banks are more concerned about credit risk (53% versus 43% among commercial and investment banks) l The commercial banks tend to be slightly more concerned about market risk (28% versus 23% among investment and retail banks) Retail banks

Banks are in the business of selling liquidity Pursuing profits necessarily thins capitalization and leaves little margin for error “The common feature of the financial services industry—banks, brokerage firms, hedge funds—is that there is a small amount of equity and a large amount of financing supporting the firm’s assets,” says Robert Chersi, former CFO of Fidelity Investments and now a professor of finance at Pace University in New York “Financial services firms rely on other people to finance them, and most of that financing is short-term It can disappear in an instant.” Credit and liquidity risk represent two faces of the same phenomenon Banks borrow via shortterm instruments in order to finance the longerterm instruments that they sell to their customers That leverage can be lost quickly as funding is withdrawn At best the bank is left without products to sell; at worst, as occurred with Lehman and Barings, the liquidity whipsaw can destroy the bank—but this kind of disaster scenario is typically preceded by expectations that the bank’s creditors will default The problem with forecasting liquidity crises to date is that liquidity risk has been difficult to model “It’s a risk that only materialises in extreme situations and is very much a binary risk,” says Michael O’Connell, a managing director at Aon Risk Solutions But according to survey respondents, the use of big data offers the promise of linking seemingly unconnected external events in real time—events that could presumably precede a In which risk areas will your organisation face the greatest challenges in the next three years?

% of all respondents using Big Data tools 31 Preventing credit card fraud 26 Guarding against loan defaults 24 Meeting liquidity requirements Supporting compliance and reporting Anticipating market trends the chances of default (cited by 45%) The executives didn’t just highlight the opportunity— they also went further in saying that big data had helped them achieve useful results When asked about success in applying big data to risk management activities, the top two results were related to credit The problem is that data inevitably goes stale: “When you apply for a mortgage, you provide the bank with current information on your assets and your employment,” says Ozgur Kan, who heads the Berkeley Research Group’s Credit Risk Analytics practice “After that, they not collect more information about you, and don’t really know whether there was a change in your circumstances.” That leads to scenarios tailor-made for behavioural models powered by data from a mix of sources: payment behavior, interactions with the bank via the website or call centers, anything available from the three big credit bureaus, and potentially social media activities and other public sources of information While there has always been a large volume of data on default and recovery rates for borrowers and loan structures, that data can now be supplemented by behavioural information, from both internal and external Source: Economist Intelligence Unit survey, July, 2014 sources, and often updated on a timelier basis In-house data typically covers what was purchased, the amount, the date, time and location, and aspects such as recent changes of address or authorisations for others to use cards Data from external data sources (such as credit scores, location data, or online behavior patterns) can not only increase accuracy, but also cut down on false positives (which can reduce revenue, as they cause the bank to deny valid transactions) Of course, the costs of outside data acquisition can be high, and internal data offers an advantage that outside data can never replicate: It typically revolves around customer touchpoints—emails, website usage, call centers—and offers a deep view into the organisation’s interaction with customers that third-party vendors cannot replicate Says Mr Thomas “We can text mining on phone calls and merge that with transactional, demographic and product data, and the result is a robust data set that enables us to have a much better understanding of who our customers are, what their patterns are, and what sorts of triggers we might need to identify.” Limiting the discussion to avoiding losses—the traditional focus of risk managers—fails to give big data its due “It’s not just for risk, and it’s not just Which of the following areas presents the biggest opportunities for Big Data to improve performance in preventing credit fraud?

% of all respondents We have separate analytics teams that combine analytical and subject matter expertise focussed on specific areas of risk management We have a centralised analytics team that responds to requests for service from risk and compliance users throughout the organisation We have a multidisciplinary analytics centre of excellence that develops specialised skills, standards and best practices for the organisation 38 29 19 Each functional area or business line employs its own risk analysts We not have a structured approach to the use of risk analytics 48 Source: Economist Intelligence Unit survey, July, 2014 © The Economist Intelligence Unit Limited 2014 Retail banks and big data: Risk and compliance executives weigh in Big data as the key to better risk management two centralised approaches (more so among commercial and investment banks than among retail banks) They’re also slightly more likely to use the service-center approach and a great deal more likely to adopt an analytics centre of excellence approach Among top performers, 27% also have analytics centres of excellence that cut across disciplines and functions, compared with 17% of lowerperforming firms Conversely, these high performers are less likely to use separate analytics teams that focus on a single area of risk management, which is the most common approach across all banks Key takeaways Risks grow as markets become more tightly linked, banks become more concentrated, and banking organisations become more complex Regulators are demanding more metrics, more transparency, and better documentation of data Although banking has always been built on data, today’s data is bigger, faster and more varied, requiring new and different tools Moreover, big data also holds more promise for mitigating risk and recognising opportunities, especially when novel and diverse data sources are integrated into traditional risk management, underwriting and sales frameworks Banks see liquidity and credit risk as presenting the biggest challenges They also see those two types of risk as offering the biggest potential for improvement Many survey participants hope that big data can help the bank anticipate liquidity crises However, the more common applications revolve around predictive modeling for fraud prevention and closer monitoring of borrowers to predict loan defaults Almost all banks are investing in big data to improve their risk management, but the banks that a better job at managing risk are moving more aggressively As big data and risk expertise grows more specialised, the best-performing banks— especially commercial and investment banks—are moving towards more centralised units that can develop expert skills, common standards and best practices that support and enhance their organisations Finally, the same big data infrastructure used to mitigate risks can also be used to pursue new sources of revenue “Whether it’s guarding against fraud or selling something new, being able to pull data from 80 different businesses enables us to get ahead of problems before they’re problems,” says Wells Fargo’s Mr Thomas About the survey?
