Given venezuela's past behavior all 16 exchanges will probably be heavily nationalized.
Venezuela seized a General Motors factory in the country last year and has always had a strong anti-capitalist stance which contributed towards venezuela being in the crisis it is in now. Venezuela faces the same issue russia faced under stalin and china faced under mao. Replacing a private sector with government run enterprises(or heavy state regulation) doesn't work as socialism fails to create value or address economic and financial demand as efficiently as markets which are incentivized via competition.
Google and apple are examples of this. Both are large corporations that began and were run out of someone's garage. This defines the most efficient method of creating value. Allowing people to create their own business, patent their own ideas and innovate in a way limited by their own imagination. The trouble with states like venezuela is socialists have all the power, they want to limit competition, run and control everything with an iron fist in a way which satisfies their egos/greed rather than solves problems or deals with issues faced by society.
Socialists in venezuela have waged a passive aggressive war against capitalism for decades and only succeeded in the limiting the private sectors ability to create value and solve economic problems. This in turn led to an economic downturn which began well before price of oil began to decline and has little or nothing to do with petrol prices imo.
Venezuela seizes GM plant as crisis escalatesAmid turmoil punctuated by skyrocketing prices, unemployment, low oil prices and failed economic policies, the government seizure put an abrupt end to GM's operations -- a fate that other companies have faced.
"GM is not the first and they’re not going to be the last because the government of Venezuela is desperate for any assets they can take," said Peter Quinter, Miami-based chair of law firm GrayRobinson's Customs and International Trade Law Group. "It really is a vicious cycle they're in."
The Venezuelan government has previously seized assets belonging to U.S. companies, including those of cleaning products maker Clorox in 2014, glassmaker Owens-Illinois in 2010 and nationalized a rice mill operated by Cargill.
GM denounced the South American country's actions as an "illegal judicial seizure of its assets" and vowed a legal battle, but the company's protections are minimal in a country with a dubious commitment to the law.
https://www.usatoday.com/story/money/2017/04/20/general-motors-venezuela-plant-seizure/100684954/ If exchanges in the country are nationalized or heavily regulated by the venezuelan government, I'll go out on a limb here and predict they will be run far more inefficiently with more corruption than other exchanges and as a result they will have a difficult time competing as their userbase and trading volume will likely be low.
