capital flow

Short-term capital flows are often greatly influenced by exchange rates. When the local currency depreciates, domestic investors and foreign investors are unwilling to hold various financial assets denominated in local currency, and will convert them into foreign exchange, leading to capital outflow. At the same time, due to the continuous exchange of foreign exchange, the demand for foreign exchange is in short supply, which will push the local currency exchange rate further down.

On the other hand, when there is a trend of appreciation of local currency abroad, domestic investors and foreign investors try to hold various financial assets denominated in local currency, which will lead to capital inflows. At the same time, since foreign exchange has been converted into local currency, the oversupply of foreign exchange will further promote the exchange rate of local currency.
