The Impact of Deposit Modeling on Interest Rate Risk in the Banking Book (IRRBB) sensitivity metrics: a worked illustration
by Chih Chen, East West Bank, August 2024
The BTRM is particularly chuffed when one of our Alumni go on to publish with us, and even more so when the subject matter is such a topical one! Chih Chen, who is with East West Bank in San Francisco, has written a particularly helpful piece on modelling of customer deposit behaviours and how this of value in the IRRBB space. Quoting from the Abstract, we note that, “The banking industry is inherently exposed to interest rate risk, which arises from the mismatch between the interest-rate sensitivities of assets and liabilities. This mismatch can lead to significant fluctuations in a bank’s Net Interest Income (NII) and Economic Value of Equity (EVE) when interest rates change. In recent years, the dynamic nature of deposit behaviors has emerged as a significant factor influencing interest rate risk in the banking book. Conventional Asset Liability Management (ALM) modeling approaches for NII and EVE often overlook the evolving nature of deposit behaviors, leading to inaccurate assessments of a bank’s exposure to interest rate changes.”
All ALCO members, as well as Treasury and Treasury Risk teams in banks, will want to read this article and thereby gain some further insight into what all this means for their bank’s NII and EVE sensitivities.

The Changing Business Landscape: Balance Sheet Management Priorities for Resilient Banks
by Dr Diyama Abu Laban & Professor Moorad Choudhry, March 2024
Banks come in very many different shapes and sizes.
In the 2020s there are banks that offer a sophisticated digital-only service with not just financial products accessible via their “app” but also the goods and services of partner firms in different industries. At the same time, there are banks
that do not offer any kind of digital service via desktop internet or app at all, and whose customers continue to interact with it via physical branch, post and/or telephone. Innovation, together with efficient and helpful customer service, are
the preserve of only some banks.
And yet…

Quantum Computing: Applications to banking
by Giuseppe Colucci, January 2021
Many financial institutions are currently investigating the possibilities of benefiting (and securing themselves) from the quantum leap, i.e. the advent of quantum computation on a large scale.
Portfolio optimisation, Monte Carlo simulations and pricing derivatives are only a few of the many applications for which a quantum computer will outperform even the fastest supercomputers.
This brief article presents an overview of the applications of quantum computing to banking.

SOFR Overnight Index Swap Curve Construction
by Ioannis Rigopoulos, December 2020
We are very excited about this article written by Ioannis Rigopoulos from Deriscope, which will be of interest to any market practitioner involved in transitioning from USD Libor to Secured Overnight Financing Rate (SOFR) and using SOFR-linked interest rate swaps for hedging.
In a paper notable for its accessibility and instant applicability, the author presents a step-by-step guide to constructing the SOFR OIS yield curve, with some very handy Excel inputs and outputs exhibits shown as well. There is also useful discussion of the practical issues associated with constructing a continuous discount function, and the author solves these issues neatly.
For those requiring a refresher on the SOFR rate and its calculation there is detail on that too. Very highly recommended.

Bond Markets: “Dirt” in the Clean Price.
by K. Boovendran, September 2020
Bond market pricing follows age-old and time-honoured principles of corporate finance and present value. A dealer of fixed income securities focuses on yield, and the price is calculated by using the PV principle. Accuracy is taken for granted. However the whole concept of bond mathematics makes a number of assumptions, which are not necessarily realistic.
The author finds two discrepancies in the calculation of dirty price and accrued interest which causes the clean price to be distorted. He shows how and why the formulae used are incorrect, and that the present value factor is over-estimated by the use of inappropriate formulae. This results in over-payment of the dirty price to the seller. Within the dirty price, there is over-payment on account of accrued interest, with the issue being that often full accrued interest is paid instead of its present value. Both these factors distort the clean price, leading to improper accounting of the transactions.
The author suggests a modified compounding formula to rectify the distortions. Both the existing and suggested formulae have been tested for their accuracy. The author concludes by discussing comparative advantages of using the modified compounding formula and the practical implications for fixed income fund managers.

Hedge Fund Returns Replication
by Jaafar Husain – Quant Analyst, Bank ABC, October 2017
In this article we will introduce an effective statistical approach to replicate hedge fund returns. The approach is based on a carefully designed stepwise regression procedure. The objectives of the regression procedure are to 1) identify the strategies and markets to which a hedge fund manager is exposed, and 2) to analyze the progression of these exposures over time. While a hedge fund manager will continually change their overall exposure to exploit market anomalies, we wouldn’t expect a manager who for many years traded in the long/short equity space to suddenly switch to the stressed equity space. The regression procedure is designed to capture such strategy drifts.

Establishing A Broad Client Liabilities Strategy
by David Castle, September 2016
One of the key tenets of a coherent strategic ALM policy is an integrated approach to raising customer liabilities. When we say integrated we mean an articulated strategy that seeks to create the optimum liabilities mix and one that complements the asset mix side of the balance sheet. The sixth in our series of Working Papers is authored by David Castle and is entitled “Establishing a Broad Client Liabilities Strategy”. Mr Castle presents one way to make an excellent start in getting such an optimising process underway.”
