Разработка системы регуляторной отчетности

Разработка системы регуляторной отчетности

Регуляторная отчётность — не разовая задача при получении лицензии, а ongoing compliance обязательство. Регулятор ожидает периодические отчёты, и пропуск дедлайна или ошибка в данных — нарушение лицензионных условий.

Типы регуляторной отчётности

Periodic reports (периодические): квартальные и годовые отчёты регулятору о деятельности. Включают: объём транзакций, количество клиентов, инциденты, AML статистику.

Suspicious Activity Reports (SAR): при обнаружении подозрительной активности. В большинстве юрисдикций — 15-30 дней с момента обнаружения.

Currency Transaction Reports (CTR): в США при транзакциях > $10,000 наличными/крипто. Не все юрисдикции требуют аналог.

Incident Notifications: при major security incidents, breaches — уведомить регулятора в течение 4-72 часов.

Annual compliance report: годовой отчёт о состоянии AML программы, включая audit findings.

Архитектура reporting системы

  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 {
  // Автоматическое создание периодических отчётов
  async generatePeriodicReport(
    type: "QUARTERLY" | "ANNUAL",
    period: DateRange,
    jurisdiction: string
  ): Promise<RegulatoryReport> {
    
    const [
      transactionStats,

    const reportData = this.formatForJurisdiction(jurisdiction, {
      period,
      transactions: transactionStats,
      customers: customerStats,
      aml: amlStats,
      incidents: incidentLog,
    });

SAR автоматизированное формирование

class SARService {

    const user = await this.db.getUser(alert.userId);
    const transactions = await this.db.getAlertTransactions(alertId);
    
    // Автоматически генерируем narrative на основе alert данных
    const narrative = this.generateNarrative(alert, user, transactions);
    
    const sar: SAR = {
      id: crypto.randomUUID(),
      alertId,
      status: SARStatus.DRAFT,
      
      filingInstitution: {

  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 `

Deadline management

// Calendar напоминаний для 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 * * *") // каждый день в 9:00
async checkReportingDeadlines() {
  const upcomingReports = await this.db.getUpcomingReports(30); // следующие 30 дней
  
  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);
    }
  }
}

Полная система регуляторной отчётности с автогенерацией периодических отчётов, SAR workflow и deadline management — 3-4 недели разработки.
