According to the different objects of supervision, the forms of foreign exchange market supervision are divided into direct supervision and indirect supervision. Direct supervision means that the foreign exchange regulatory agencies directly control the demand and supply of the foreign exchange market in quantity. In countries under strict control, all foreign exchange earnings must be sold to foreign exchange banks designated by the state, and all foreign exchange expenditures must be approved. Compared with direct supervision, indirect supervision mainly adopts some measures that indirectly affect the supply and demand of foreign exchange, including setting up a foreign exchange stabilization fund and intervening in the market exchange rate; Import license and quota system.
