根因分析
中国人民银行为在岸人民币设定每日中间价并允许±2%的波动区间，而离岸人民币自由浮动；在岸与离岸市场之间的流动性差距在压力时期（如月末、贸易战）可达300-500个基点，若合同未指定货币变体则会导致结算错配
English
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

-
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
-
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
-
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
无效尝试
常见但无效的做法:
-
75% 失败
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
-
80% 失败
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
-
85% 失败
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)
