Total U.S. trade was up 2.79% through May, but trade in South Florida was down 5.32%, according to Coral Gables-based WorldCity, which crunched Census Bureau Data.

A continuing factor in the less-than-stellar South Florida numbers was lower trade in gold as commodity prices for the metal have slumped.

Global trade in the Miami Customs District fell to $47.67 billion through the first five months of 2014, WorldCity found. Exports decreased 6.91% while imports fell 3.27%.
