Imports of goods and services jumped 8.9 percent to $8.27 billion in the period, the Bank of Tanzania (BOT) said in its monthly economic review for June. "The value of goods imported increased ... largely due to a rise in the value of imported oil, food stuffs, fertilisers and other consumer goods," the bank said. The value of imported oil increased to $1.9 billion compared to $1.4 billion in the preceding year, it said. During the period in question, the country bought 3.4 million tons of oil, compared with 2.7 million tons a year before. The east African economy's goods and services exports jumped 15.2 percent in June from a year earlier to $5.09 billion, with gold exports surging 67.4 percent to $1.38 billion. Tanzania is Africa's third-largest gold producer. Gold continued to outstrip tourism as Tanzania's biggest foreign exchange earner, making up 44.1 percent of exports, while manufactured goods made up 20.7 percent, the bank said. Tourism -- categorised as travel -- generated $1.23 billion, up from $1.16 billion a year before. The industry has traditionally been Tanzania's leading source of foreign exchange before being overtaken by gold in recent months. Traditional exports -- tea, coffee, cashew nuts and tobacco, among others -- earned $451.9 million, down 8 percent over the previous year, due to a decline in export volumes and a fall in cotton prices. Tanzania's economy is largely driven by mining, farming and tourism. But sectors such as manufacturing, telecommunications and financial services have been growing in recent years and contributing more. The central bank said bank credit to the private sector rose 14.1 percent in the year to June, compared with a 32.8 percent increase a year before. The bank said official gross reserves rose to $3.48 billion at the end of June -- or 5.5 months of import cover -- from $2.93 billion at end June 2009, boosted partly by funds from the International Monetary Fund's Exogenous Shocks Facility. The central bank aims for the country to have no less than five months of import cover.
