The Venezuelan government decided to devalue it's currency the bolivar 32% against the dollar. This has the immediate impact of making it's exports cheaper and be able to pay off its debts in cheaper currency. On the flip side, it will cause massive inflation.
Welcome to a country run by a socialist government.
So overnight if you were a hard working Venezuelan middle class person, all of your hard earned bolivars has now suddenly lost 46% of its value. If instead you had held your savings in gold instead of bolivars you would have had at least preserve your wealth.
The same thing is happening here in teh United States, just not overnight. Someone could have $20,000 in the bank and be able to buy lets say $20,000 worth of wheat, or oil, or cotton, gold, or some other commodity. However, if there were a massive Venezuelan currency devaluation, then you would still have the $20,000 in your ban and you would still be able to buy $20,000 worth of commodities. However, if inlfation hits in the $20,000 you would not get as much of the commodity after the devaluation than before it.
Today socialist or socialist leaning governments are in charge of the United States, Europe, Japan, and may other parts of the world. As long as they remain in power, we will have more currency devaluation.
