Of course, developing as a potential reserve currency created a substantial vulnerability. Both Japan and Germany were slow in liberalizing their domestic financial systems as they tried to limit capital inflows for a substantial period of time in order to avoid rapid currency appreciation and the consequent erosion of their export competitiveness.
当然，变成潜在储备货币的确会加剧波动性。在国内金融体系自由化方面，日本和德国当年的脚步都很慢；在相当长一段时期内，它们试图限制资本流入，以避免本币过快升值，削弱出口竞争力。
