Answer: Fall; rise foreign demand for domestic currency.
Step-by-step explanation:
The exchange rate must be fall to create a domestic currency surplus in an economy. For example:
Suppose, the ongoing exchange rate of India is $1 = Rs.70
So, if a person wants to buy a good worth of $2, then he have to pay Rs.140 for this good. When the exchange rate falls to $1 = Rs.60, now he have to pay only Rs.120 for this good. Hence, domestic currency surplus of Rs.20 created in an economy.
To maintain this level of fixed exchange rate, which created a domestic currency surplus, so government must increase the foreign demand for their domestic currency, to wipe out all the created domestic currency surplus in this economy.
