That process began in April 2009, when China launched the pilot RMB Trade Settlement Scheme (RTSS), which enables enterprises, especially larger ones, to channel their funds between Mainland China and Hong Kong. As a result, an offshore RMB market, known as the CNH market, was created in Hong Kong alongside the onshore market, now dubbed the CNY market.
事实上，12月人民币的突然贬值反应出中国跨境资本流的自由化。这一过程始于2009年4月，当时中国开始试点人民币贸易结算机制（RTSS），企事业单位（尤其是大型企事业单位）可以在大陆和香港之间转移资金。结果，离岸人民币市场，即CNH市场，在香港被建设起来，与在岸市场（现在称为CNY市场）并行。
