According to Aureliano (2020), "The Forex market is the most active financial market on the planet, and also has the highest liquidity. Every day, traders from all the corners of the globe take part in foreign exchange transactions worth more than $4 trillion. Because this market touches every country's economy and is a highly interconnected marketplace, it is extremely sensitive to geopolitical events that can cause an immediate effect on the prevailing currency rates." (para. 2)

Given the powerful influence of geopolitical forces on trade of goods, services, and currencies as explained in Aureliano (2020),, is the concept of "free trade" still relevant in international economics today?
