The General Ledger As a Key Component of a Banking Platform

What is a General Ledger and Why is it Important?

A General Ledger (GL) can be thought of as the ultimate financial journal for a digital banking platform. It records every transaction, tracking incoming and outgoing money, and monitors the overall financial status. Simply put, the General Ledger is the reliable cornerstone of any digital banking platform. It ensures:

• Transparency
• Regulatory compliance
• Smooth operations

It is comparable to the beating heart of a company’s financial system, consistently keeping everything running as it should.

Risks and Consequences of Non-Compliance with General Ledger Standards

Non-compliance with market and security requirements can lead to potential issues. Here are the top five problems that can arise in case of a malfunctioning or non-existent General Ledger:

• Loss of Client Funds. A malfunctioning GL could cause erroneous transaction processing, potentially leading to a loss of client funds. This is one of the most serious issues and could even lead to legal complications.
• Data Integrity Issues. If the GL doesn’t function correctly, the accuracy and consistency of financial data could be compromised. This can cause incorrect balances and transactions to be recorded incorrectly or not at all.
• Lack of Immutable Record. One of the main features of a GL is the immutability of its data. Without a fully functional GL, historical financial data could be altered, leading to inaccuracies and potential fraud.
• Lack of Funds Segregation. Without a reliable GL, separating client funds from the platform’s operational funds could become difficult. This could potentially risk customer funds and breach financial regulations.
• Regulatory Violations. The GL is essential for complying with financial regulations. A malfunctioning or non-existent GL could lead to regulatory penalties or legal consequences.

Operating with Multiple Bank Providers: The General Ledger as the Source of Truth

The General Ledger functions as the ultimate source of truth within a digital banking platform. No matter how many banks are integrated or how frequently service providers change, the GL persistently retains a transparent and consistent record of all transactions. For instance, your digital banking system might incorporate integrations with various banks or BaaS to bring together diverse banking products. None of these external, integrated banks should know the actual balance of the end user. Predominantly, they are responsible for providing access to payment networks. As a result, it’s crucial to ensure your system processes all transactions as the sole source of truth for your end users.

The ‘plug-in and plug-out’ mechanism used to incorporate various bank providers into the platform guarantees that each bank’s operations remain independent, providing necessary services without jeopardizing the integrity of the GL. Whether these integrations facilitate SWIFT transactions, local transfers, or deposit services, they interact with the platform, yet all transactions are ultimately logged and stored in the GL.

From the perspective of the end user, these changes are virtually imperceptible. They can carry on with their transactions, completely unaware of the back-end switches between providers, while the GL continues to keep an accurate record. Hence, in a dynamic environment marked by numerous integrations and continuous changes, the General Ledger remains the immutable, definitive, and dependable source of truth. The consistency of the GL ensures that no matter how frequently bank providers change, the integrity of the data remains unimpaired, rendering the digital banking platform a trustworthy and reliable system for users.

The General Ledger in Action with Finhost

At Finhost, we utilize tools and approaches that handle data differently than traditional relational databases due to its immutable nature. We maintain a complete and verifiable history of all data changes using a cryptographic hash function (SHA-256) to create a secure output that verifies the integrity of these transactions. Moreover, we regard it as a main component in the system, constantly maintaining and updating it according to all compliance and modern approaches.
