A high-performance financial risk analysis plugin combining sparse inference for efficient market signal processing with graph neural networks for transaction network analysis. The plugin enables real-time anomaly detection, portfolio risk scoring, and automated compliance reporting while maintaining the explainability required by financial regulators (SEC, FINRA, Basel III).
## Features
- **Portfolio Risk Analysis**: Calculate VaR, CVaR, Sharpe ratio, Sortino ratio, and max drawdown
- **Anomaly Detection**: Detect fraud, AML violations, and market manipulation in transactions
- **Market Regime Classification**: Identify current market regime through historical pattern matching
- **Compliance Checking**: Automated verification against Basel III, MiFID II, Dodd-Frank, AML, and KYC
- **Stress Testing**: Run historical and hypothetical stress scenarios on portfolios
## Installation
### npm
```bash
npm install @claude-flow/plugin-financial-risk
```
### CLI
```bash
npx claude-flow plugins install --name @claude-flow/plugin-financial-risk

## Security Considerations
### Regulatory Compliance
This plugin is designed for financial regulatory compliance:
| Requirement | Implementation |
|-------------|----------------|
| **PCI-DSS Compliance** | No storage of PAN/CVV in plugin memory |
| **SOX Compliance** | Immutable audit logs for all risk calculations |
| **Data Encryption** | AES-256 for data at rest, TLS 1.3 in transit |
| **Key Management** | HSM or secure enclave for cryptographic keys |
| **Segregation of Duties** | Separate roles for trading, risk, and compliance |
### Role-Based Access Control
```typescript
const roles = {
TRADER: ['portfolio-risk', 'market-regime'],
RISK_MANAGER: ['portfolio-risk', 'anomaly-detect', 'stress-test', 'market-regime'],
COMPLIANCE_OFFICER: ['compliance-check', 'anomaly-detect'],
AUDITOR: ['compliance-check'], // Read-only with full audit access
QUANT: ['portfolio-risk', 'market-regime', 'stress-test']
};
```
### Audit Logging (SOX/MiFID II)
All calculations are logged with:
- Timestamp with microsecond precision
- User ID and role
- Transaction IDs affected
- Portfolio state hash
- Model version used
- Input/output hashes for reproducibility
Logs are retained for 7 years per MiFID II requirements and available for regulatory inspection within 72 hours.
### WASM Security Constraints
| Constraint | Value | Rationale |
|------------|-------|-----------|
| Memory Limit | 1GB max | Handle large transaction datasets |
| CPU Time Limit | 60 seconds | Allow complex risk calculations |
| No Network Access | Enforced | Prevent data exfiltration |
| No File System Write | Enforced | Analysis-only mode |
| Sandboxed Data Access | Enforced | No direct database queries |
### Input Validation
All inputs are validated using Zod schemas:
- Stock symbols: `/^[A-Z0-9.]{1,10}$/`
- Position quantities: between -1 billion and 1 billion
- Transaction amounts: between -1 trillion and 1 trillion
- Batch limits: maximum 100,000 transactions per request
- Timestamps: ISO 8601 format, within reasonable date range
- Entity identifiers: Alphanumeric with limited special characters
### Rate Limiting
```typescript
const rateLimits = {
'portfolio-risk': { requestsPerMinute: 60, maxConcurrent: 5 },
'anomaly-detect': { requestsPerMinute: 100, maxConcurrent: 10 },
'stress-test': { requestsPerMinute: 10, maxConcurrent: 2 },
'market-regime': { requestsPerMinute: 120, maxConcurrent: 10 },
'compliance-check': { requestsPerMinute: 30, maxConcurrent: 3 }
};
```
## Performance
| Metric | Target |
|--------|--------|
| Portfolio VaR calculation | <100ms for 10K positions |
| Transaction anomaly scoring | <5ms per transaction |
| Market regime classification | <50ms for 1-year history |
| Compliance check | <1s for full entity scan |
