Qatar will maintain its position as the fastest growing economy, with its real GDP expected to soar by around 21 percent, said QNB Capital in a study, an affiliate of Qatar National Bank. The country's budget surplus is projected to rise to $8.5 billion (4.9 percent of GDP) in 2011/2012 before easing slightly to $7.5 billion (3.8 percent of GDP) in 2012/2013,” said the study. “Based on our forecasts for growth and Qatari oil prices, we expect that actual revenue will grow by around 18 percent to $51 billion in 2011/2012 and by a further 3.8 per cent to $53 billion in 2012/2013.” Qatar had projected a surplus of QR9.7 billion ($2.6 billion) in its current fiscal year, which started on April 1. Expenditures were estimated at QR117.9 billion and revenue, mostly from the sale of oil and liquefied natural gas, at 127.5 billion. Qatar recorded its highest fiscal surplus during 2009-2010 because of a surge in revenue. Despite an increase in spending, the surplus leaped to an all time high of around QR46.3 billion in the 2009
