Step 1: Understanding the Concept:
A flexible (floating) exchange rate system is determined by the market forces of demand and supply of foreign exchange.
Step 2: Detailed Explanation:
Statement 1 is True: In a flexible system, if there is a BoP deficit (excess demand for foreign currency), the exchange rate rises (depreciation of domestic currency).
This makes exports cheaper and imports costlier, eventually correcting the deficit. The reverse happens for a surplus.
Statement 2 is False: Overvaluation or undervaluation is a characteristic of a Fixed Exchange Rate System, where the government sets a rate different from the market equilibrium.
In a purely flexible system, the currency is always at its market-clearing value, so "official" over/under valuation does not exist in the same sense.
Step 3: Final Answer:
Statement 1 is correct regarding the self-correcting nature of BoP, while Statement 2 is incorrect as it describes a fixed rate problem.
