The maintenance of money's value is said to depend on the monetary authorities. What might the monetary authorities do to devalue a currency in foreign exchange markets?

Answer: One thing that could be done to devalue a currency is to issue more currency into their markets.

Explanation:

Any asset or goods can be based on how scarce the product or assets it. The authorities in the foreign markets could make more currency and this will devalue the currency because the market will be saturated. The money/currency will still be at the same value as before but the purchasing power will be reduced since there is an added supply of money in the economy.
