How Behavioural Biases Distort Risk Decisions with Svetlana Kardan
The same financial risk information can produce materially different committee decisions, depending on how it is presented. In this RiskMasters — The Download , Svetlana Kardan , former HSBC Group Head of IRRBB and creator of Psychology of Treasury , explores how behavioural biases and organisational dynamics influence Treasury risk management and decision-making under pressure. Drawing on her experience across financial markets and Asset and Liability Management, Svetlana identifies three particularly dangerous behavioural biases. Sunk cost bias can make reversing a losing position psychologically more difficult than continuing to accept further losses. Groupthink can create the appearance of consensus even when individuals privately disagree, while deference to authority can lead people to follow the most senior person rather than those with the most relevant information. The conversation also examines what happens when commercial ambitions, Treasury constraints and risk appetite pull in different directions. Without clear priorities agreed in advance, decisions can become dominated by the most influential voices rather than the organisation's established risk boundaries. Perhaps the most revealing insight concerns how the presentation of information shapes collective judgement . Svetlana explains that presenting a single Economic Value of Equity (EVE) sensitivity figure can encourage committee members to treat an estimate as fact. Presenting a range of outcomes instead invites discussion about assumptions and uncertainty. Even the sequence matters. Leading with the worst-case scenario can make subsequent outcomes appear reassuring, while presenting the base case first can make the same worst-case scenario seem extreme. The underlying financial position remains unchanged, yet the committee's response can be materially different. This raises a fundamental challenge for risk governance: accurate information does not necessarily guarantee objective decisions when its interpretation is influenced by behavioural biases, hierarchy and presentation. In this extract: Why sunk cost bias can prevent institutions from reversing deteriorating financial positions How groupthink creates apparent consensus while concealing individual disagreement Why deference to authority can override more relevant information during a crisis How competing commercial objectives, Treasury constraints and risk appetite influence decisions Why agreed decision-making priorities can prevent the loudest voice from dominating How presenting risk as a range rather than a single figure changes committee discussions Why the sequence of base-case and worst-case scenarios can materially influence collective judgement This extract comes from my CPD-accredited RiskMasters conversation with Svetlana Kardan , When Models Meet Behaviour: The Psychology of Treasury Risk . 🎧 Listen to the full episode of RiskMasters for the complete conversation on Treasury risk management, behavioural psychology, financial models, governance and decision-making under uncertainty. https://www.aevitium.com/post/cpd-svetlana-kardan-on-riskmasters
