How to classify foreign exchange by source and use?

According to source use: it is divided into trade foreign exchange, non-trade foreign exchange and financial foreign exchange.

Trade foreign exchange, also known as physical trade foreign exchange, refers to foreign exchange derived or used in import and export trade, that is, international payment means formed by international commodity circulation.

Non-trade foreign exchange refers to all foreign exchange except trade foreign exchange, that is, all foreign exchange that is not derived from or used for import and export trade, such as labor foreign exchange, remittance, donation foreign exchange, etc.

Different from trade foreign exchange and non-trade foreign exchange, financial foreign exchange belongs to a kind of financial asset foreign exchange, such as inter-bank trading foreign exchange, which is neither derived from tangible trade nor intangible trade, nor used for tangible trade, but used for the management and manipulation of various currency positions. According to the market trend: it is divided into hard foreign exchange and soft foreign exchange, or strong currency and weak currency.
