Puerto Rico

It's been called the "Greece of the Caribbean." Puerto Rico is more than $72 billion in debt. But because it's not a state, it can't use bankruptcy protection to help it restructure its debt.

More than a century ago, Puerto Rico used to produce world-class coffee. Now farmers there are trying to rebuild the industry by focusing on growing higher-quality beans, which command higher prices.

The island's power authority owes $9 billion. Power costs are already high, but bondholders are pushing for rate hikes. That may deter employers, which would further hurt the territory's weak economy.

After years of recession and rampant tax evasion, the U.S. territory is desperate to renegotiate its $73 billion debt. But it can't declare bankruptcy, and plans to raise taxes face strong resistance.

Decades of industrialization have left the island reliant on imported food. But change is coming — from government subsidies for small farmers, to classes that teach school kids how to grow food.

The U.S. territory implemented an unusual version of the Affordable Care Act. Insurers must offer coverage to everyone. But there's no mandate for people to buy it, and there are no subsidies to help.
