Visualising Money Trails: Inter-Bank Transfers in Forensic Audits

Tracing the movement of funds, or mapping money trails, is a core task for forensic investigators, auditors, and underwriters to uncover cases involving fraud, tax evasion, and financial irregularities. In India, financial crimes often involve complex layers of transactions, and bank statements are a valuable source that aid investigators in uncovering irregularities.

Bank statements are a chronological record of transactions and a gold mine for forensic auditors. Tracking money flow, how it enters, moves through, and exits an entity’s financial system through transfers, cheques, and bank-to-bank transactions, helps identify suspicious patterns that may signal potential fraudulent activities.  

The Reserve Bank of India (RBI) has reported a significant surge in bank frauds, with the amount involved rising 194 per cent, or almost three times, to Rs 36,014 crore in the year ended March 2025, compared to Rs 12,230 crore in the previous year.

This surge demands robust methods that not only detect fraudulent activities but also analyse complex financial movements at scale. Visualising money trails helps translate vast amounts of data related to complex inter-bank transfers into clear, compelling charts and graphics for actionable insights.

Forensic auditors rely on specific techniques to uncover these hidden financial activities.

The Critical Role of Inter-Bank Transfers in Uncovering Money Trails

Inter-bank transfers, the movement of funds between accounts held in two or more different banks, are one of the most valuable sources of evidence in investigating economic crimes. They create digital records that help forensic and enforcement auditors trace illicit fund flows.

Money trails that track inter-bank transfers can reveal hidden relationships, shell-company networks, fund diversion, laundering patterns, and transactions that fraudsters attempt to obscure within complex banking systems. Every bank transfer creates independent, time-stamped records that fraudsters find harder to manipulate.

Whilst inter-bank transfers provide invaluable evidence, analysing them presents distinct challenges for forensic teams:

• In the current scenario, the person or organisation under investigation is most likely to have accounts in multiple banks, numerous UPI and credit card lines, making it extremely cumbersome to track funds comprehensively without missing transactions.
• Each bank provides statements in different formats, making it extremely difficult to analyse and compare thousands of transactions consistently. Precisa’s Bank Statement Analyser eliminates this barrier by automatically extracting and standardising data from 850+ banks and 1200+ formats, allowing investigators to focus on pattern analysis rather than data wrangling.
• It is almost impossible to recognise complex circular transactions or identify subtle red flags through manual scrutiny. Hence, forensic teams require technology to aid them and support their expertise.

Inter-bank Transfers Expose Hidden Money Flows

Scrutinising these transfers reveals unusual patterns that expose hidden criminal activity. Frequent transfers of round sums, transfers to high-risk jurisdictions, or transactions inconsistent with known business activities help investigators in the following ways:

Unmasking Hidden Networks

Fraudsters use multiple accounts across different banks to conceal connections between shell companies, fake vendors, and family accounts, among other purposes. Tracking inter-bank transfers helps connect the dots and reveal money trails that are not visible when examining financial statements alone.

Smart Money Trail Detection feature from Precisa helps track inter-bank transfers and circular transactions between seemingly unrelated accounts without any manual intervention.

Detecting Layering

Money launderers use layering; they break funds into smaller transfers to hide their origin. Forensic auditors can uncover round-tripping, circular transfers, and first-in-first-out patterns by tracing the flow of funds.

Revealing Fund Diversion

Corporations often resort to over-invoicing, loan siphoning, and related-party transactions to divert funds. Inter-bank transfers track funds leaving business accounts, moving to shell companies, subsidiaries, or third parties, and help investigators detect fraud.

Inter-bank records are instrumental in uncovering embezzlement and theft by tracking if company or client funds were transferred to personal accounts.

Techniques for Visualising Money Trails

A combination of various techniques and tools aids investigators and auditors in visualising fund movement between different accounts and institutions in their investigations. Visual mapping, in the form of graphs and flow diagrams, turns complicated transaction data into clear trails that experts can follow. The discussion below focuses on these:

Network Graphs

Network graphs are dynamic, interactive maps that visually represent relationships between suspects, shell companies, and beneficiaries. These aid auditors in spotting hidden connections and complex networks, enabling them to see how accounts are connected and detect shared nodes.

The AML solution’s Advanced Transaction Intelligence feature conducts UPI transaction analysis by identifying Reference Numbers (RRNs) and producing detailed money trail visualisations, which allow investigators to map transaction paths within intricate financial networks.

Flow Diagrams and Timelines

These are graphical representations that track the sequence and movement of funds from source to destination across various banks and jurisdictions. Underwriters and investigators gain insights into the transaction timing and spot unusual patterns, such as rapid deposits and withdrawals, through timeline views.

The AML tool presents interactive charts and flow diagrams that illustrate how funds move between banks, enabling users to visually track money trails and identify complex transfer patterns across accounts or institutions.

First-In-First-Out (FIFO) Analysis

FIFO analysis maps accurate source-to-destination flows across accounts, which is crucial for identifying how illicit funds are layered to avoid detection and determining if money came from legal or illegal sources.

Automated tools aid forensic teams in spotting money laundering through transactional pattern analysis that identifies suspicious activity. Transaction data is presented in insightful charts, graphs, and dashboards, enabling lenders to quickly identify patterns, anomalies, and trends for more informed lending decisions.

Conclusion

Mapping inter-bank transfers and visualising money trails has become indispensable in the current scenario, as financial crimes become increasingly sophisticated. Leveraging advanced analytics turns complex inter-bank transaction data into clear, easy to understand visual insights, allowing investigators, underwriters, and auditors to effectively detect suspicious activities, unravel hidden networks, and respond proactively to emerging threats.
