The effect of imports and exports on currency

CFA Level III
#1

If the Korean market is experiencing a decrease in export goods, while the US is experiencing a rise in exports and both trends will affect the value of the won relative to the USD…

Why would this cause the won to depreciate relative to the USD? Would a decrease in exports mean that less people are buying the won to purchase korean goods and at the same time - more people would be buying the USD to purchase US goods. As a result, the won depreciates and USD appreciates?

Is my logic correct?

So from my understanding, a fall in exports usually would imply low GDP growth. If there’s low growth, you won’t attract foreign investments in your country and hence your currency loses value and depreciates.
