Financial regulators say that decline is due to fluctuations in foreign exchange rates and asset prices.

金融监管机构表示，这种下降是由于外汇汇率和资产价格的波动。

There are many factors that contribute to changes in price, like government regulations, supply and demand and foreign exchange rates.

影响价格变化的因素有很多，例如政府法规、供求关系和汇率。

Floating exchange rate refers to the exchange rate that is determined by the supply and demand in the foreign exchange rate, and the government does not assume the obligation to maintain the exchange rate level.

浮动汇率是指由外汇汇率中的供求关系决定的汇率，政府不承担维持汇率水平的义务。
