Abstract: Implementing robust data lake architectures for Internal Liquidity Stress Testing (ILST) and Internal Liquidity Monitoring System (ILMS) represents a transformative approach to liquidity risk management in financial institutions. This comprehensive solution integrates S3-compatible storage, Apache Spark, Hive catalog, Apache Iceberg, and Dremio to address persistent challenges in data volume handling, integration complexity, and analytical limitations. The architecture enables financial organizations to centralize disparate data sources, enhance analytical capabilities, facilitate real-time monitoring, support historical analysis, and strengthen regulatory compliance. Through systematic implementation following established methodologies—including thorough assessment and planning, robust data modeling and governance, phased deployment, seamless system integration, and comprehensive automation—institutions can maximize the benefits while effectively mitigating challenges related to data security, technical complexity, change management, data quality, and performance optimization. The evidence demonstrates that financial institutions implementing such architectures experience significant improvements in operational efficiency, analytical depth, risk management effectiveness, and regulatory reporting accuracy, ultimately strengthening their overall liquidity risk management capabilities in increasingly complex and regulated financial environments.
