Value at Risk (VaR)<\/b><\/h2>\n<p><b>Value at Risk (VaR)<\/b><span style=\"font-weight: 400;\">:\u00a0 It is one of the most widely used measures in <\/span><span style=\"font-weight: 400;\">financial risk management<\/span><span style=\"font-weight: 400;\">, serving as a benchmark to estimate potential losses within a portfolio or investment over a given period of time under normal market conditions. At its core, VaR provides an answer to a very practical question: <\/span><i><span style=\"font-weight: 400;\">\u201cWhat is the worst expected loss that could occur over a specific time horizon at a given level of confidence?\u201d<\/span><\/i><\/p>\n<p><span style=\"font-weight: 400;\">While calculating the historical mean provides a vital baseline estimate for potential cost overruns, relying on the average alone is statistically insufficient for final budgeting decisions. Knowing the mathematical average tells us where the historical centre of gravity lies, but it does not indicate the likelihood <\/span><i><span style=\"font-weight: 400;\">(at what confidence?)<\/span><\/i><span style=\"font-weight: 400;\"> of our specific project landing near that number. Because capital infrastructure projects are highly volatile, we cannot assume our project will neatly match the mean. To establish a defensible budget, we must move beyond a single average value and determine the exact statistical confidence interval\u2014quantifying the probability that our project will remain within a specified funding range.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In a standard trading style, VaR quantifies the maximum loss that is unlikely to be exceeded with a certain degree of confidence. For instance, if an analyst states that a portfolio has a one-month VaR of $1 million at a 95% confidence level, this can be interpreted to mean that, 19 out of 20 months, the portfolio is expected to either make a profit or, at worst, lose no more than $1 million. Conversely, in the remaining 5% of the time, losses could exceed this threshold, which reflects the tail risk that VaR does not capture.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Unlike a standard trading style VaR, which explicitly includes a specific time parameter, a Reference Class Forecasting (RCF) model calculates a maximum cost overrun at a chosen confidence level over the entire lifecycle of the project. To account for this missing temporal dimension and prevent eroded purchasing power, risk managers overlay macroeconomic inflation projections onto the RCF-adjusted cost overruns.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The concept of <\/span><i><span style=\"font-weight: 400;\">confidence level<\/span><\/i><span style=\"font-weight: 400;\"> is central to understanding VaR. A confidence level represents the degree of statistical certainty with which the estimate is made. A 95% confidence level suggests a high probability that actual outcomes will remain within the projected limits, while a 95% level offers even greater assurance.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, as the confidence level increases, the corresponding VaR estimate also rises because it must account for a broader range of adverse scenarios. This increase is driven by the dependence of VaR on the statistical Z-Score: the higher the confidence level, the larger the Z-Score, and thus, the higher the estimated potential loss. Importantly, VaR does not grow linearly with confidence but rather at an accelerating rate, since covering rarer extreme events requires progressively larger buffers.<\/span><\/p>\n<p><span style=\"text-decoration: underline;\"><b>Estimating VaR<\/b><\/span><\/p>\n<p><span style=\"font-weight: 400;\">Below are the methods on how VaR is measured :\u00a0<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-7908 size-medium\" src=\"https:\/\/www.theirmindia.org\/blog\/wp-content\/uploads\/2026\/07\/p5_5-300x99.png\" alt=\"Estimated VaR\" width=\"300\" height=\"99\" srcset=\"https:\/\/www.theirmindia.org\/blog\/wp-content\/uploads\/2026\/07\/p5_5-300x99.png 300w, https:\/\/www.theirmindia.org\/blog\/wp-content\/uploads\/2026\/07\/p5_5-1024x338.png 1024w, https:\/\/www.theirmindia.org\/blog\/wp-content\/uploads\/2026\/07\/p5_5-768x253.png 768w, https:\/\/www.theirmindia.org\/blog\/wp-content\/uploads\/2026\/07\/p5_5.png 1086w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<table>\n<tbody>\n<tr>\n<td><strong>Parametric VaR<\/strong><\/td>\n<td><strong>Non-Parametric VaR<\/strong><\/td>\n<td><strong>Implied Volatility<\/strong><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Parametric VaR, also known as delta-normal VaR, assumes that asset or portfolio returns follow a specific statistical distribution, most commonly the normal distribution<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Non-parametric VaR avoids assumptions about the distribution of returns and instead relies on actual market data to model risk.

Stress Testing<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Stress testing is a critical <\/span><a href=\"https:\/\/www.theirmindia.org\/what-is-enterprise-risk-management-erm\" target=\"_blank\" rel=\"noopener\"><b>enterprise risk management<\/b><\/a><span style=\"font-weight: 400;\"> tool used to evaluate <\/span><span style=\"font-weight: 400;\">organisational resilience,<\/span><span style=\"font-weight: 400;\"> and the financial resilience of capital projects under extreme but plausible economic and delivery conditions. A key motivation for stress testing stems from the observation that during major macroeconomic shocks or systemic industry failures, correlations between <\/span><span style=\"font-weight: 400;\">project risks<\/span><span style=\"font-weight: 400;\"> rise sharply.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">There are two main approaches to conduct stress testing:\u00a0<\/span><\/p>\n<table>\n<tbody>\n<tr>\n<td><b>Historical Crisis<\/b><\/td>\n<td><b>Hypothetical or pre-determined stress scenarios<\/b><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Risk managers apply cost overruns and contractor defaults from past crises (like COVID-19 or the 2008 crash) to current projects. This tests pipeline resilience against real-world systemic shocks.<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Risk managers simulate forward-looking, extreme shocks like hyperinflation, extended approval delays, and tier-1 contractor insolvencies etc., This checks project vulnerability against unprecedented market threats.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><span style=\"font-weight: 400;\">Now the main question is &#8211; &#8220;Are extreme economic crises not already covered in Reference Class Forecasting (RCF) uplifts?
