What is Bank Statement Analysis?

Bank statement analysis is the systematic process of reviewing, interpreting, and extracting meaningful insights from bank statements. It involves categorizing transactions, identifying patterns, detecting anomalies, and assessing financial health and behavior.

Primary Objectives

  • • Assess creditworthiness and repayment capacity
  • • Detect fraudulent transactions and suspicious patterns
  • • Verify income stability and cash flow
  • • Identify risk factors in lending decisions
  • • Ensure compliance with regulatory requirements

Types of Bank Statement Analysis

Corporate account analysis for business loans, vendor assessment, and commercial credit evaluation.

Compliance & Fraud

Regulatory compliance checking and fraud detection for anti-money laundering and financial crime prevention.

Key Elements to Analyze in Bank Statements

Multi-Account Analysis

Always analyze statements from all accounts. Single account analysis misses 60% of critical insights like loan repayments, investments, and inter-account transfers.

Trend Analysis Over Time

Compare 12-24 months of statements to identify seasonal patterns, business cycles, and long-term financial health trends.

Cross-Verification

Verify declared income against actual credits, and cross-check with IT returns, Form 26AS, and other financial documents.

Automated Tools Implementation

Leverage AI-powered tools for initial processing while maintaining human oversight for complex cases and final decision-making.

Regulatory Compliance Considerations

Bank statement analysis must comply with various Indian regulations including RBI guidelines, PMLA, KYC requirements, and data protection laws.

RBI Guidelines

  • • Loan application scrutiny
  • • Enhanced due diligence
  • • Income assessment norms

PMLA Compliance

  • • Suspicious transaction reporting
  • • KYC verification
  • • Record keeping requirements

Data Protection

  • • Consent for processing
  • • Data minimization
  • • Secure storage practices
