为什么汇率会变动？

汇率是指不同国家或地区之间的货币兑换比率。由于不同国家的经济状况、货币政策、贸易关系等因素的影响，汇率会不断发生变化。以下是一些影响汇率变动的因素：

首先，一个国家的经济状况是影响汇率的重要因素之一。当一个国家的经济增长强劲时，其货币通常会升值，因为该国具有更高的信誉和更强的偿付能力。相反，当一个国家经济衰退或通货膨胀时，其货币通常会贬值，因为该国的信誉和偿付能力受到损害。英文翻译为：Why do exchange rates change?

Exchange rate refers to the ratio at which currencies of different countries or regions are exchanged. Exchange rates change constantly due to various factors such as economic conditions, monetary policy, trade relationships, etc. Here are some factors that affect exchange rate fluctuations:

Firstly, a country's economic condition is one of the important factors that affect exchange rates. When a country's economy grows strongly, its currency usually appreciates, as the country has higher creditworthiness and stronger repayment ability. Conversely, when a country experiences economic recession or inflation, its currency usually depreciates because the country's creditworthiness and repayment ability are damaged.
