Executive Head: Interest Rate Risk In The Banking Book

Summary

As the Head of Interest Rate Risk in the banking book, my primary responsibility is to maintain margin stability and protect the bank from interest rate fluctuations. This role requires understanding of key risk factors, including portfolio composition, funding structures, and macroeconomic indicators across various jurisdictions. Prior to my tenure at Absa Treasury, I served as a Risk Advisory Consultant at ING Bank and ABN AMRO Bank in the Netherlands. My responsibilities included developing balance sheet forecasting models to provide the Executive Committee with strategic insights into margin management, liquidity risk, and interest rate risk in the banking book, as well as swaps hedging and scenario analysis. I initiated and led risk projects to successful completion, notably in the behavioral modeling of mortgages and savings. Additionally, I have occupied several roles at Nedbank Group Limited, including Manager: ALM Risk Modeler and Credit Risk Analyst. In my capacity as a Credit Risk Analyst, I contributed to various areas such as impairments forecasting and the oversight of Nedbank Group's credit portfolio, ensuring compliance with credit policies, procedures, and standards. I have also been an active member of several bank management committees, including the Home Loans Credit Committee and the Property Finance Credit Committee.
