More details out this week from failed Greece debt talks have thrust the talk of "capital controls" back into the global financial conversation.
Earlier reports out of Germany hinted at the possibility that Athens would be required to impose capital controls if no cash-for-reform deal was reached by the weekend, though Greece officials denied that was the case.
But just what are capital controls?
Technically, a capital control is a roadblock put in place by a government to restrict the flow of money out of or into its country. They can be directed at individuals, industries, companies, banks, and other governments and effect currencies, equities and debt.
Emerging markets are where capital controls are most often put in place as a developing economy does not usually have enough currency, gold or other capital needed during a crisis. Though Greece may not necessarily be a developing economy, it meets the standard for lacking capital as the country struggles to devise a way to pay the 1.5 billion euros it owes the IMF by June 30. And that's just the first payment among many.
