The need to constantly control intraday liquidity positions, carry out stress-tests (“what-if” simulations) and comply with regulatory requirements is very heavy on resources. And is seen as not sustainable in the long term.
The large and diverse range of sources throughout the bank, to perform these calculations leads to reconciliation issues
The liquidity team cannot easily access the most granular level of data they need to properly manage liquidity requirements in a timely manner (with liquidity changing very quickly in stressed conditions). They have to go through many requests to their IT colleagues or use shortcuts (with their simulations are not as pertinent as an access to the entire dataset would allow).
