# AI tells a multinational corporation to settle trade in CNY (offshore) without considering the onshore-offshore RMB liquidity gap and the PBOC's daily fixing band

- **ID:** `banking/cny-on-offshore-liquidity-gap`
- **Domain:** banking
- **Category:** currency_exchange
- **Error Code:** `PBOC-CNY-LIQ-2001`
- **Verification:** ai_generated
- **Fix Rate:** 82%

## Root Cause

The PBOC sets a daily central parity rate (fixing) for onshore CNY (CNY) with a ±2% trading band, while offshore CNH (CNH) floats freely; the liquidity gap between onshore and offshore markets can reach 300-500 pips during stress periods (e.g., month-end, trade wars), causing settlement mismatches if the contract does not specify the currency variant

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|

| CIPS Phase 2 (2022) | active | — | — |
| HKEX USD/CNH Futures Contract Spec (2024) | active | — | — |

## Workarounds

1. **Specify the settlement currency as 'CNY (onshore)' or 'CNH (offshore)' in the trade contract; use a 'CNY fix' clause referencing the PBOC's daily fixing rate at 9:15 AM Beijing time** (95% success)

   ```
2. **Open a 'two-way' RMB account with a bank that has both onshore (CIPS) and offshore (CHATS) access, such as HSBC or Standard Chartered; execute the settlement via the appropriate channel based on the fixing rate** (85% success)

3. **Use a 'CNY futures' contract on the Hong Kong Exchange (HKEX) to lock in the offshore rate, then settle the physical trade at the futures price; this requires a margin account with a futures broker** (70% success)

## Dead Ends

- **** — Cross-currency swaps between CNY and CNH are limited to $1 billion daily notional due to PBOC capital controls; during high volatility, the swap market dries up, leaving the gap unhedged (75% fail)
- **** — The counterparty may be in a different jurisdiction (e.g., Hong Kong) and cannot access onshore CNY directly; the resulting FX conversion adds 100-200 bps in cost (80% fail)
- **** — Convergence only occurs during low-volatility periods; historical data shows CNH can diverge from CNY by up to 2% for weeks during trade tensions (e.g., 2019-2020) (85% fail)
