The net surplus for 2010/11 after the transfer is KD3.13 billion, the final data showed.

In June, Kuwait\'s parliament approved a budget of KD19.4 billion for the 2011/12 fiscal year, the biggest since at least 2003 and a 19 percent jump from the previous year, basing it on an oil price of $60 per barrel. Analysts polled by Reuters in June forecast that given the higher oil prices, Kuwait will post a fiscal surplus of 20.2 percent of GDP in 2011/12, the highest in the Gulf. Concerned about regional unrest, Gulf oil exporters have boosted government spending to ease social tensions. Kuwait has seen limited protests and frequent challenges to the government by its parliament, the most outspoken in the Gulf Arab region.
