There has been a lot of worry that the increasingly penurious Venezuelan government may cancel the Petrocaribe program that helps Caribbean nations (and El Salvador) buy Venezuelan oil. The fear is that fragile Caribbean economies will collapse if Caracas withdraws its support.
I think these worries are misplaced.
Petrocaribe finances Caribbean oil purchases on a sliding scale. When the price is between $30 and $40 per barrel, it will finance 25% of the purchase price. When the price is $90 per barrel (as it was back in July), Petrocaribe finances 40% of the purchase price. The terms are laid out in Article IV the Petrocaribe Cooperation Agreement.
Upshot: the price of Venezuelan oil is currently $39 per barrel with no subsidy. Six months ago, Caribbean countries had to shell out $59 in cash for a barrel of oil valued a hair below $99. It is true that if Petrocaribe holds the Caribbean countries will have to stump only $29 in cash ... but at the end of the day, $39 < $59.
Meaning that even if Venezuela abandons its Bolivarian ideals and dumps its Caribbean allies, the Caribbean countries will still be better off than they were last year.
