Main factors of currency supply?

• A. Trade; Gov Policy; Speculation; Hot money
• B. International treaties; Weather; Population; Language
• C. Tourism; Education; Cultural exchange; Demographics
• D. Currency reserves; Exchange rates; Tax; Regulation

Answer: (A)

Currency supply in the foreign exchange market is driven by real flows and financial movements that push currency into or out of circulation. Trade affects supply because when a country runs a trade surplus, foreign buyers need domestic currency to pay for exports, and exporters convert foreign earnings into domestic currency, increasing the amount of domestic currency available in the market. Conversely, a trade deficit can reduce that supply.

Government policy, especially monetary policy, directly shapes the money base and thus how much currency is pumped into or withdrawn from the economy. Tools like open market operations and reserve requirements control the amount of currency banks can create and lend, influencing the overall supply.

Speculation and hot money involve short-term capital flows seeking quick gains. Large inflows bring more domestic currency into the market, while large outflows pull currency out, causing rapid shifts in supply independent of current trade or policy fundamentals.

Other listed factors don’t fit as primary drivers: international treaties, weather, population, and language don’t directly set how much currency is circulating; currency reserves, exchange rates, tax, and regulation describe tools or outcomes rather than the core forces shaping daily currency supply.
