Use Case: Real-Time Risk Management Forecasting

The Challenge

A consumer banking institution handles a high volume of transactions, including credit card transactions, loan approvals, and fund transfers. These transactions are subject to various risks, including fraud, default, and regulatory compliance issues. The bank aims to proactively predict and mitigate these risks using real-time insights.

  2. Real-Time Analytics:
    • ClickHouse enables instantaneous analysis of incoming data streams. It quickly processes and aggregates data, allowing risk analysts to monitor trends and anomalies in real time.
  3. Machine Learning Integration:
    • Advanced machine learning models are integrated with ClickHouse. These models utilize historical data to train and continuously refine risk prediction algorithms.
  4. Fraud Detection:
    • ClickHouse rapidly processes and analyzes credit card transactions as they occur. It compares transaction patterns against historical data to detect anomalies and potential fraud in real time.
  5. Default Prediction:
    • ClickHouse’s sub-second query performance enables the bank to evaluate the creditworthiness of loan applicants almost instantly. Predictive models assess factors such as credit scores, income, and payment history to forecast default risks.
  6. Regulatory Compliance:
    • ClickHouse aids compliance teams by analyzing large datasets against regulatory requirements. It ensures that transactions adhere to anti-money laundering (AML) and Know Your Customer (KYC) guidelines.
  7. Customized Dashboards:
    • Risk analysts and business leaders can access real-time dashboards powered by ClickHouse. These dashboards display current risk exposure, trend analysis, and key risk indicators.
