The existence of unofficial exchange markets is often driven by several factors:
Government Restrictions: When a government imposes strict controls on certain commodities or currencies, it can create a demand for these items outside the official market. Economic Instability: In countries experiencing high inflation or political instability, the official exchange rates might not reflect the true value of the currency, prompting people to seek better rates in the unofficial market. Tax Evasion: Businesses and individuals might engage in unofficial exchanges to avoid paying taxes. Supply and Demand: Sometimes, the official market cannot meet the demand for certain goods or services, making the unofficial market a viable alternative.
