摘要翻译：
研究了世界60种货币的汇率时间序列的相关矩阵。给出了金、银和铂的最小生成树(MST)图。对这些图形以及四种不同的货币组（主要的、流动的、较少流动的和不可交易的）讨论了像缩放一样的逆幂。美元和相关货币的比例变化最大。

英文摘要：
  Correlation matrices of foreign exchange rate time series are investigated for 60 world currencies. Minimal Spanning Tree (MST) graphs for the gold, silver and platinum are presented. Inverse power like scaling is discussed for these graphs as well as for four distinct currency groups (major, liquid, less liquid and non-tradable). The worst scaling has been found for USD and related currencies.
