# Global Regulatory Harmonization Suite (GRHS)

## Overview

The GRHS establishes DBIS as a central harmonization authority aligning international regulations, sovereign banking laws, global AML/KYC frameworks, CBDC issuance standards, and trade finance and securities rules.

## Harmonization Pillars

### Pillar I – Monetary Harmonization
- FX stabilization rules
- Sovereign liquidity minimums
- CBDC interoperability requirements

### Pillar II – Legal Harmonization
- Standardized settlement law
- Unified arbitration and enforcement
- Cross-border recognition of DBIS authority

### Pillar III – Compliance Harmonization
- FATF-Plus standards
- Integrated sanctions regime
- AML/KYC equivalency protocols

### Pillar IV – Trade Harmonization
- ICC UCP/URDG/eUCP uniform adoption
- Standardized digital document formats
- Commodity and security tokenization rules

## Regulatory Equivalence Protocol (REP)

A sovereign may be declared **Regulatory Equivalent** if:

```
REP_SCORE = (compliance + transparency + AML_strength + CBDC_maturity) / 4 ≥ 95%
```

Grants:
- Fast-track settlement privileges
- Preferential liquidity access
- Reduced oversight frequency

## Usage Example

```typescript
import { grhsService } from '@/core/compliance/grhs';

// Initialize GRHS
await grhsService.initialize();

// Calculate REP score
const repScore = await grhsService.calculateREPScore(sovereignBankId);

// Assess compliance
const compliance = await grhsService.assessCompliance(sovereignBankId);

// Grant fast-track privileges
if (repScore.equivalent) {
  await grhsService.grantFastTrackPrivileges(sovereignBankId);
}
```
