The Iranian economy is predicted to grow by 1-2% this year (from March 21, 2014, to March 20, 2015). Inflation should drop from 37% the previous year to 25% this year, Iran.ru reports. Iran has been declining in the past 2-3 years.
Lifting sanctions will not have an immediate effect on economic recovery. Iran has hardly seen any investment in the petroleum industry or power plant construction in the past years. The situation may stay the same this year.
