为什么要储备外汇？

外汇储备是指一国政府持有的可兑换货币资产，通常包括美元、欧元、日元等。外汇储备是一个国家国际储备的重要组成部分，对于该国的经济和金融稳定具有重要意义。那么，为什么要储备外汇呢？

首先，外汇储备的主要作用是维持汇率稳定。当一国货币汇率下跌时，该国政府可以通过使用外汇储备干预市场，购买本国货币，以稳定汇率。这可以防止货币大幅贬值，从而避免经济动荡。英文翻译：Why Do Countries Stock Foreign Exchange?

Foreign exchange reserves refer to the convertible currency assets held by a country's government, usually including currencies such as the US dollar, the euro, the Japanese yen, etc. Foreign exchange reserves are an important component of a country's international reserves and play a significant role in maintaining economic and financial stability. So, why do countries stock foreign exchange?

Firstly, the main function of foreign exchange reserves is to maintain exchange rate stability. When the currency exchange rate of a country falls, the government can intervene in the market by using foreign exchange reserves to purchase the domestic currency to stabilize the exchange rate. This can prevent sharp depreciation of the currency and thereby avoid economic turbulence.
