This type of financial modeling has become increasingly important for banks since the 2008 financial crisis, when it became apparent that many banks had taken on too much risk without properly assessing the potential downside. As a result, regulators around the world are requiring banks to use more sophisticated methods, such as VaR, to ensure they are managing their risk appropriately. This means that banks must now use more computing power than ever before to perform these analyses.
The result is an increase in energy consumption and heat generated by the high-performance computers used for VaR calculations. If not used efficiently, this heat can harm the environment and contribute to climate change. However, if used properly, it could represent a great opportunity for banks to reduce their carbon footprint and make a positive contribution to decarbonization efforts.
