Iran's President Hassan Rouhani has said last month's nuclear deal with world powers has already had a positive impact on the country's economy.
Mr Rouhani's comments came while presenting next year's budget to parliament.
He said after the "success" of the talks, people showed more interest in investing in businesses and the stock exchange.
The nuclear deal eases some sanctions in return for a halt to parts of Iran's uranium enrichment programme.
Western sanctions over the country's suspect nuclear programme last year dealt a heavy blow to the economy, especially the currency.
The 68 billion-dollar (£41.7bn) budget predicts a US dollar set to 26,000 Iranian rials. The rial is currently 29,000 to the dollar. Parliament will decide on the budget within months.
