Here’s a simplified example of how machine learning can analyse trends from ISO 20022 payment data:

Data Collection: Gather ISO 20022 payment data from various sources such as banks, financial institutions, or payment processors. This data typically includes information like transaction amounts, timestamps, sender and receiver information, transaction types, and any relevant metadata.

Data Preprocessing: Clean and preprocess the raw ISO 20022 data. This step involves tasks such as handling missing values, encoding categorical variables, scaling numerical features, and splitting the data into training and testing sets.

Feature Engineering: Extract relevant features from the ISO 20022 data that can help in detecting trends. These features could include transaction frequency, average transaction amount, transaction volume per customer, transaction patterns over time, and so on.

Model Selection: Choose appropriate machine learning algorithms for trend detection. Commonly used algorithms for this task include time series analysis techniques like ARIMA (AutoRegressive Integrated Moving Average), machine learning algorithms like decision trees, random forests, or more advanced methods like deep learning with recurrent neural networks (RNNs) or Long Short-Term Memory (LSTM) networks.

Training the Model: Train the selected machine learning model on the preprocessed ISO 20022 data. The model learns to identify patterns and trends in the data based on the provided features.

Validation and Evaluation: Validate the trained model using a separate validation dataset or through cross-validation techniques. Evaluate the model’s performance using appropriate metrics such as accuracy, precision, recall, or F1-score.

Trend Detection: Once the model is trained and validated, it can be used to detect trends in new ISO 20022 payment data. The model can identify patterns such as increasing or decreasing transaction volumes, unusual spikes in transaction amounts, changes in customer behavior, and other trends that may be of interest to financial institutions or businesses.

Continuous Monitoring and Improvement: Continuously monitor the model’s performance over time and retrain it periodically with updated data to ensure that it remains accurate and effective at detecting trends in ISO 20022 payment data.

ISO 20022 Structured Data: Enhancing Cross-Border Payments

ISO 20022 offers a structured framework for exchanging financial messages, enabling richer and more standardized data to accompany payment instructions. This structured data includes not only essential payment details but also additional information such as structured postal addresses, remittance data, and purpose codes. Leveraging this structured data can significantly enhance the efficiency, transparency, and accuracy of cross-border payments.

> Structured Postal Addresses

In cross-border payments, accurate address information is crucial for routing payments to the correct beneficiary. ISO 20022 facilitates the inclusion of structured postal addresses within payment messages, ensuring consistency and completeness. These structured addresses can include elements such as street name, city, postal code, and country code, providing financial institutions with the necessary information to process payments accurately.

> Structured Remittance Information

Remittance information refers to details provided by the payer to the payee, specifying the purpose or context of the payment. ISO 20022 allows for the inclusion of structured remittance data within payment messages, enabling standardized formats for describing payment references, invoice numbers, and other relevant information. This structured remittance information streamlines reconciliation processes for both the payer and the payee, reducing manual effort and minimizing errors.

> Purpose Codes

Purpose codes are standardized identifiers used to categorize the purpose of a payment, such as salary payments, supplier invoices, or tax payments. ISO 20022 supports the inclusion of purpose codes within payment messages, providing clarity and consistency in the classification of transactions. These purpose codes facilitate regulatory compliance, financial reporting, and data analysis, enabling financial institutions to track and monitor payment activities more effectively.

Use Cases with Structured Data and Machine Learning

> Address Verification and Correction

Machine learning algorithms can be employed to validate and correct structured postal addresses included in payment messages. By analyzing historical address data and employing address validation techniques, ML models can identify inaccuracies or inconsistencies in address information and suggest corrections in real-time. This ensures that payments are routed correctly and reduces the risk of payment delays or errors due to invalid address information.

> Automated Remittance Matching

Machine learning algorithms can automate the process of matching structured remittance information with corresponding invoices or payment references. By training on historical data and learning patterns in remittance information, ML models can accurately identify relevant transactions and reconcile them with corresponding accounts receivable or payable records. This automation streamlines reconciliation processes for businesses, reducing manual effort and accelerating cash flow.

Purpose Code Classification and Reporting

Machine learning algorithms can classify payment transactions based on purpose codes included in payment messages, enabling automated categorization and reporting. By training on labeled data sets and learning patterns in purpose code usage, ML models can accurately categorize transactions according to their intended purpose, such as payroll, vendor payments, or tax remittances.
