Credit Portfolio Management in the IFRS 9 / CECL and Stress Testing Era: The post-crisis world presents portfolio managers with the significant challenge to asimilate in day-to-day management the variety of conceptual frameworks now simultaneously applicable in the assessment of portfolio credit risk: The first major strand is the widespread application of regulatory stress testing methodologies in the estimation of regulatory risk capital requirements The second major strand is the introduction of new accounting standards (IFRS 9 / CECL) for the measurement and disclosure of expected credit losses
Release of version 0.3 of the Concentration Library: Further building out the OpenCPM set of tools, we release version 0.3 of the Concentration Library. This python library for the computation of various concentration, diversification and inequality indices. The below list provides documentation URL’s for each one of the implemented indexes Atkinson Index Concentration Ratio Berger-Parker Index Herfindahl-Hirschman Index Hannah-Kay Index Gini Index Theil Index Shannon Index Generalized Entropy Index Kolm Index The image illustrates a simple use of the library where the HHI and Gini indexes are computed and compared for a range of randomly generated portfolio exposures.
First Release: OpenCPM NPL Database: Further building out the OpenCPM set of tools, we took the European Banking Authority’s recommended Non-Performing Loan templates and created an #opensource production grade database for capturing NPL portfolio data sets. Motivation for Building an open source database based on EBA’s Standardized NPL Templates In a recent insightful piece Overcoming non-performing loan market failures with transaction platforms, Fell et al. dug deeply into the market failures that perpetuate the NPL problem.
Open Risk released version 0.1 of the Transition Matrix Library Motivation: State transition phenomena where a system exhibits stochastic (random) migration between well defined discrete states (see picture below for an illustration) are very common in a variety of fields. Depending on the precise specification and modelling assumptions they may go under the name of multi-state models, Markov chain models or state-space models. In financial applications a prominent example of phenomena that can be modelled using state transitions are credit rating migrations of pools of borrowers.
How much digital bank can we fit in a 50 euro bill? Much has been said about the impact of Big Data and high-end GPU computing on the provision of digital financial services. At Open Risk we wanted to explore the boundary of what is possible at the diametrically opposite end of the cost spectrum: What is the absolutely minimum cost for providing digital financial services? . In this post we begin the journey of finding out the answer to that question and it promises to be fascinating!

Fintech Risk Events: Fintech Risk Events is an open catalog of observed and publicized operational failures of fintech business models. The catalog aims to document, in due course, such events reasonably accurately, to allow risk managers understand the (potentially new) vulnerabilities of new financial services models. Scope The scope of the operational risk database is Fintech companies. By that we mean newly established financial services providers that operate exclusively via new (digital) platforms and are (mostly) unregulated.

Unbundling the Banks: A How To Guide: Talk of unbundling the banks is all the rage these days (if we believe the fintech startups). Yet upon closer inspection one gets the feeling that these optimistic people might not necessarily know exactly what they are trying to unbundle, the true complexity of a medium to large bank, which in turn reflects, at least in part, the complexity of our modern financial system.
Open Source Risk Data with MongoDB and Python: Open source software is all the rage those days in IT and the concept is making rapid inroads in all parts of the enterprise. An earlier comprehensive survey by Gartner, Inc. found that by 2011 more than half of organizations surveyed had adopted open-source software (OSS) solutions as part of their IT strategy. This percentage may have currently exceeded the 75% mark according to open source advisory firms.
Open Risk API: If you work in financial risk management you will most likely recognize where the following sentence is coming from: One of the most significant lessons learned from the global financial crisis that began in 2007 was that banks information technology (IT) and data architectures were inadequate to support the broad management of financial risks. This had severe consequences to the banks themselves and to the stability of the financial system as a whole For those lucky few risk managers not being affected by inadequate IT systems, the excerpt is from the Basel Committee’s Principles for effective risk data aggregation and risk reporting (2013).
Resources fo concentration risk management: Concentration Risk Management is a staple of risk management. Open Riskdeveloped a unique and novel set of risk management resources to assist with building in-house knowledge for managing credit concentration risks. Resources range from courses and online manuals to open source calculators and mobile eLearning games. In this post we have a brief summary of what is available, you can find more details by clicking on the embedded links
The periodic table of risk elements: You know the periodic table of elements, even if you flunked your science courses! It is the large colorful and blocky table that hanged on every school’s classrooms before becoming yet another mobile app. The periodic table is one of the early and iconic achievements of science. It lists all the pure chemical elements found in nature, the building blocks of all possible material substances.
Visualizing the Stress of US Banks: A recurring cycle of regulatory stress testing exercises has become the new normal in the banking world, at least on the two shores of the northern Atlantic. The periodicity of the European stress testing heartbeat has not yet been firmly established. Did we just miss a beat in 2015 (a so called palpitation) or will the European cycle have two (or more) years periodicity? Who knows.
Concentrating on Concentration Risk: Senior economists such as Ben Bernanke were still studying the Great 30’s Depression when the financial crisis struck in full force circa 2007. Given the complexity of the modern economic and financial landscape compared to the blessed good old days - we have no reports of FWMD (financial weapons of mass destruction) from back then - we can reasonably project that economists will be studying and pontificating on causes and remedies for the current crisis for the next 100 years or so
