Regulatory Reporting System Development

Development of Regulatory Reporting System

Regulatory reporting is not a one-time task when obtaining a license, but an ongoing compliance obligation. The regulator expects periodic reports, and missing a deadline or data error constitutes a license violation.

Types of Regulatory Reporting

Periodic reports: quarterly and annual reports to the regulator about activities. Include: transaction volume, number of customers, incidents, AML statistics.

Suspicious Activity Reports (SAR): upon discovery of suspicious activity. In most jurisdictions — 15-30 days from discovery.

Currency Transaction Reports (CTR): in the US for transactions > $10,000 in cash/crypto. Not all jurisdictions require equivalent.

Incident Notifications: upon major security incidents, breaches — notify regulator within 4-72 hours.

Annual compliance report: annual report on the state of AML program, including audit findings.

Reporting System Architecture

interface RegulatoryReport {
  id: string;
  type: ReportType;
  period: { from: Date; to: Date };
  jurisdiction: string;
  regulatorEmail: string;
  dueDate: Date;
  status: "DRAFT" | "REVIEW" | "SUBMITTED" | "ACKNOWLEDGED";
  data: ReportData;
  submittedAt?: Date;
  acknowledgedAt?: Date;
  submissionReference?: string;
}

class RegulatoryReportingService {
  // Automatic creation of periodic reports
  async generatePeriodicReport(
    type: "QUARTERLY" | "ANNUAL",
    period: DateRange,
    jurisdiction: string
  ): Promise<RegulatoryReport> {
    
    const [
      transactionStats,
      customerStats,
      amlStats,
      incidentLog,
    ] = await Promise.all([
      this.aggregateTransactionStats(period),
      this.aggregateCustomerStats(period),
      this.aggregateAMLStats(period),
      this.getIncidents(period),
    ]);
    
    const reportData = this.formatForJurisdiction(jurisdiction, {
      period,
      transactions: transactionStats,
      customers: customerStats,
      aml: amlStats,
      incidents: incidentLog,
    });
    
    return this.db.createReport({
      type,
      period,
      jurisdiction,
      data: reportData,
      dueDate: this.calculateDueDate(type, period),
      status: "DRAFT",
    });
  }
  
  private async aggregateTransactionStats(period: DateRange): Promise<TransactionStats> {
    return this.db.query(`
      SELECT 
        COUNT(*) as total_count,
        SUM(usd_amount) as total_volume_usd,
        AVG(usd_amount) as avg_transaction_usd,
        COUNT(DISTINCT user_id) as unique_users,
        asset,
        direction
      FROM transactions
      WHERE created_at BETWEEN $1 AND $2
      GROUP BY asset, direction

  }
  
  private async aggregateAMLStats(period: DateRange): Promise<AMLStats> {

    ]);
    
    return {

Automated SAR Generation

class SARService {
  async createSAR(alertId: string, context: SARContext): Promise<SAR> {
    const alert = await this.db.getAlert(alertId);
    const user = await this.db.getUser(alert.userId);
    const transactions = await this.db.getAlertTransactions(alertId);
    
    // Automatically generate narrative based on alert data
    const narrative = this.generateNarrative(alert, user, transactions);
    
    const sar: SAR = {
      id: crypto.randomUUID(),
      alertId,
      status: SARStatus.DRAFT,
      
      filingInstitution: {
        name: process.env.COMPANY_NAME,
        vatNumber: process.env.COMPANY_VAT,
        address: process.env.COMPANY_ADDRESS,
        contactEmail: process.env.AML_OFFICER_EMAIL,
      },
      
      subject: {
        name: `${user.firstName} ${user.lastName}`,
        dob: user.dateOfBirth,
        address: user.residenceAddress,
        idNumber: user.documentNumber,
        nationality: user.nationality,
      },
      
      suspiciousActivity: {
        type: this.mapAlertTypeToSARCategory(alert.triggerRules),
        dateRange: {
          from: transactions[0]?.timestamp,
          to: transactions[transactions.length - 1]?.timestamp,
        },
        totalAmount: transactions.reduce((sum, t) => sum + t.usdAmount, 0),
        currency: "USD",
        description: narrative,
      },
      
      supportingTransactions: transactions.map(t => ({
        date: t.timestamp,
        amount: t.amount,
        asset: t.asset,
        usdValue: t.usdAmount,
        txHash: t.txHash,

      })),
      
      createdAt: new Date(),
      dueDate: new Date(Date.now() + 15 * 86400000), // 15 days
    };
    
    await this.db.saveSAR(sar);
    return sar;
  }
  
  private generateNarrative(alert: Alert, user: User, transactions: Transaction[]): string {
    const totalUSD = transactions.reduce((sum, t) => sum + t.usdAmount, 0);
    const dateRange = `${formatDate(transactions[0].timestamp)} to ${formatDate(transactions[transactions.length-1].timestamp)}`;
    
    return `
Customer ${user.firstName} ${user.lastName} (DOB: ${user.dateOfBirth},

${this.describePatterns(alert, transactions)}
Based on the foregoing, this activity is being reported as suspicious.
    `.trim();
  }
}

Deadline Management

// Calendar reminders for compliance team
const REPORTING_CALENDAR: ReportingSchedule[] = [
  { jurisdiction: "Estonia", type: "QUARTERLY", dueDays: 30, recipients: ["[email protected]"] },
  { jurisdiction: "Estonia", type: "ANNUAL", dueDays: 60, recipients: ["[email protected]", "[email protected]"] },
  { jurisdiction: "Lithuania", type: "QUARTERLY", dueDays: 30, recipients: ["[email protected]"] },
];

@Cron("0 9 * * *") // every day at 9:00
async checkReportingDeadlines() {
  const upcomingReports = await this.db.getUpcomingReports(30); // next 30 days
  
  for (const report of upcomingReports) {
    const daysUntilDue = Math.ceil((report.dueDate - Date.now()) / 86400000);
    
    if ([30, 14, 7, 3, 1].includes(daysUntilDue)) {
      await this.sendDeadlineReminder(report, daysUntilDue);
    }
  }
}
