The price of Nickel is down...
Cuba holds 16 percent of the world’s nickel reserves and is currently the world’s sixth largest nickel exporter. In 2005, nickel export revenues totaled $1 billion. In 2007, the profit from nickel exports surpassed tourism profits with a gross of $2.2 billion.
However, with the price of Nickel having fallen by nearly 65%, from $34,000 to $12,000 a ton, Cuba's hard currency shortage will be even more severe than previously expected.
