The Economist/Economic Intelligence Unit provides the following Country Briefing forecast for 2009:

# We have lowered our forecasts for Iraq's fiscal deficit, after raising our oil price projections. Nevertheless, we still expect the budget to return an average deficit of US$15.6bn in 2009-10.
# Real GDP growth in 2009-10 is forecast to slow, from an estimated rate of 7.8% in 2008 to an average of 5.7%, as a tighter fiscal stance has a knock-on impact across the economy.
# Iraq's current-account deficit forecast has narrowed slightly, owing to the revision to our oil price projections. We now expect that the current account will return a deficit of US$9bn in 2009, narrowing to US$6.4bn in 2010.
