Why is Venezuela's economy such a wreck? It's a problem with much deeper and broader roots than just the turmoil in oil markets. Here's the answer in five charts:
Oil production is declining. The chart above, part of a presentation from professor Francisco Monaldi at Harvard University's Kennedy School of Government, shows that back in the '90s, Venezuela was producing nearly 3.5 million barrels of oil per day. But then Hugo Chavez came to power in 1999, and he curtailed investment in the energy sector, using the money instead for social programs.
That's led to a sharp decline in production, to only 2.6 million barrels per day. Even worse, Venezuela doesn't get paid for almost half of the oil (1.2 million barrels) it produces because it's given away to places like Cuba, or supplied to the domestic market at below-market prices.
With all that spending, despite high oil prices, Venezuela incurred massive deficits. This chart shows that even as oil hit record prices, providing a windfall in revenue, the country managed to have a deficit of more than 17 percent of GDP in 2012.
In order to spend more than it earned, Venezuela has borrowed money—lots of it. Foreign debt stands at $106 billion.
Perhaps most shockingly, Venezuela has so little to show for all that borrowing. After a whole series of booms and busts (dating back to even before Chavez came to power) Venezuela's GDP per capita is at the same level now that it was in the early 1970s.
