Forex Supply Curve Shifts Quiz: Causes of Supply Changes

A rightward shift in the forex supply curve means that at every given exchange rate, more foreign currency is available in the domestic market than before. This reflects an increase in underlying supply driven by factors such as greater export revenues, increased foreign investment inflows, or higher remittance flows, rather than a change in the exchange rate itself.

The answer is False. A change in the exchange rate causes a movement along the existing forex supply curve, not a shift. The supply curve shows the relationship between the exchange rate and the quantity of foreign currency supplied. A shift only occurs when an underlying determinant changes, such as export volumes, foreign investment levels, or remittance flows, altering supply at every exchange rate level.

A significant increase in foreign tourists brings more foreign currency into the domestic market at every exchange rate level, as visitors convert their home currencies to spend locally. This increase in supply at all exchange rates shifts the entire forex supply curve to the right, reflecting a rise in the underlying availability of foreign currency rather than a movement along the existing curve.

Export subsidies reduce the price of domestic goods for foreign buyers, stimulating demand for exports. As export volumes rise, domestic sellers receive more foreign currency, which they convert into domestic currency. This increases the quantity of foreign currency supplied at every exchange rate level, shifting the forex supply curve to the right and increasing overall foreign exchange availability.

The answer is False. A reduction in foreign direct investment inflows means fewer investors are converting foreign currency into domestic currency, so less foreign exchange enters the domestic market. This decrease in supply at every exchange rate level shifts the forex supply curve to the left, not the right, reflecting the reduced availability of foreign currency from this source.

When a major trading partner enters a recession, it reduces its spending on imports, including goods from the domestic country. Lower export volumes mean the domestic country receives less foreign currency from abroad. With less foreign exchange flowing in at every exchange rate level, the forex supply curve shifts to the left, reducing the overall supply of foreign currency in the domestic market.

Greater foreign tourist spending, increased foreign acquisitions of domestic businesses, and a rise in service exports all bring more foreign currency into the domestic economy at every exchange rate level, shifting the supply curve right. Stricter capital controls on inbound investment would restrict foreign currency inflows, reducing forex supply and shifting the curve to the left rather than to the right.

The answer is True. During harvest season, agricultural exporters sell large volumes of produce to foreign buyers, receiving significant amounts of foreign currency that are then converted into domestic currency. This seasonal surge in export earnings temporarily increases the supply of foreign exchange at every exchange rate level, shifting the supply curve to the right until the seasonal export peak subsides.

A shift in the forex supply curve is caused by a change in an underlying determinant of supply such as export volumes, tourism inflows, or foreign investment. A movement along the curve occurs when the exchange rate changes, causing suppliers to offer more or less foreign currency at the new rate. These are fundamentally different responses to different types of economic changes.

When the domestic currency appreciates, domestic exports become more expensive for foreign buyers, reducing demand for them over time. As export volumes fall, domestic sellers receive less foreign currency from abroad. This sustained decline in foreign currency inflows reduces the supply of foreign exchange at every exchange rate level, eventually shifting the forex supply curve to the left.

Declining export competitiveness reduces foreign currency earnings, fewer foreign tourists bring less foreign currency, and higher domestic interest rates that deter inflows reduce forex supply, all shifting the supply curve left. An increase in export subsidies makes domestic goods more competitive abroad, encouraging more exports and increasing foreign currency inflows, which shifts the supply curve to the right.

The answer is False. A leftward shift in the forex supply curve means less foreign currency is available in the domestic market. With reduced supply of foreign currency relative to demand, the foreign currency becomes more expensive in domestic terms, meaning the domestic currency depreciates in value. A leftward shift in forex supply therefore puts downward pressure on the domestic currency, not upward pressure.

Removing barriers to foreign portfolio investment makes it easier for international investors to purchase domestic financial assets. To do so, they convert their foreign currency into domestic currency, increasing the supply of foreign exchange in the domestic market at every exchange rate level. This inflow of foreign investment shifts the forex supply curve to the right.

If a major trading partner introduces tariffs on the domestic country's exports, foreign demand for those goods falls. The domestic country sells less abroad and receives less foreign currency from export transactions. This reduction in foreign currency inflows at every exchange rate level shifts the forex supply curve to the left, reducing the overall availability of foreign exchange in the domestic market.

When more foreign currency flows into the domestic market, its relative abundance reduces its price in domestic terms, meaning the domestic currency becomes more valuable. Greater forex supply appreciating the domestic currency means the equilibrium exchange rate shifts in favor of the domestic currency. Higher domestic inflation is not a direct or automatic consequence of increased forex supply, making it incorrect to include it as a certain outcome.
