自中国政府推动人民币国际化以来,欧盟及其成员国对人民币国际化给予了积极支持和合作。其主要动因在于:欧元的应用范围比美元要窄,且不属于避险资产,长期来看,人民币国际化对欧元的影响相对较小;中国资本项目的开放能为欧洲市场参与者和欧盟带来潜在益处;中欧在币缘政治上没有根本利益冲突,中欧在减少美元货币权力对世界经济和政治的不利冲击方面有着共同利益,在建立多元国际货币体系方面有着共同诉求。因此,中欧货币合作前景可期。但是,欧盟对“一带一路”倡议的政治疑虑、美国对欧盟及其成员国外交关系的影响可能消解中欧货币合作的未来前景。

人民币国际化、自由化,是我国在《国际货币基金协定》法律框架下,逐步有序融入国际货币金融体系的过程。从国际货币基金组织法律体系的视角看,在人民币国际化的进程中,政府行使的货币规制权即汇率制度调整权、资本项目可兑换的管辖权和储备货币的决定权为人民币国际化提供了合法依据和指引。虽然这些权利在多边国际货币法律制度下的行使存在界限和约束,但是通过综合分析可以发现,这些义务和约束并不妨碍或限制我国在汇率制度调整上的自主性及资本项目规制上的自主性。

与《国际货币基金协定》相比,《美墨加协定》货币条款的主要发展有二,一是强化了汇率操纵预警机制,二是引入争端解决机制。汇率操纵预警机制和争端解决机制在一定程度上会限制发展中国家的货币主权,但也会对国际货币体系产生一些有益影响:透明度制度能够强化基金组织的监督机制;外汇储备数据透明度和报告制度有助于防范储备资产组合调整所带来的潜在风险;争端解决机制有助于促进国际经济关系的法治化。《美墨加协定》货币条款对未来其他经贸协定的缔结可能产生重要影响。从长远来看,《美墨加协定》货币条款透明度制度与人民币汇率制度的市场化改革具有相契性,该制度不会对中国的国际金融制度产生根本性的负面影响。
