The Obama administration estimates relief from some sanctions in exchange for a temporary pause in Iran's nuclear enrichment program will amount to just $7 billion. That's a meager amount for the economy of a nation of nearly 80 million people—it's less than one month's worth of Iran's oil production and just 7 percent of Iran's overseas cash that remains frozen under the sanctions.
Still, Iranians see the move as a much needed step toward a more normal economy after years of crippling inflation and job losses.
"Markets operate on a psychological basis," says Ray Takeyh, an Iran expert at the Council on Foreign Relations and former U.S. State Department senior adviser. "The psychology of Iranian commerce has changed."
Rahmat Dehghani, a glazier, says he has been invited to discuss a new hotel project in the northeastern city of Mashhad, 550 miles (900 kilometers) east of the capital, Tehran.
"For months, the owner had delayed any discussion about his project since the future was not clear for any investment," he said.
The Iranian economy was already struggling under the weight of corruption, mismanagement and costly food, energy and cash subsides for the poor when the U.S.
Oil sales plummeted by about 1.5 million barrels per day, depriving Iran of about $80 billion since early 2012, according to the White House. At the same time, much of the revenue Iran did earn from exports to a few Asian countries that were allowed to buy Iranian oil remained out of the country. The sanctions required oil buyers to pay into locked bank accounts that Iran can access only to purchase non-sanctioned goods or humanitarian supplies.
Manufacturers found it increasingly difficult to buy crucial components to make products or keep factories running. Inflation and unemployment soared and Iran's national currency, the rial, lost more than half its value.
"People can't save, they can't invest, it's hard to buy a home, no one can trust the currency, no one knows what they really earn," says Anthony Cordesman, a Middle East and energy expert at the Center for Strategic and International Studies.
At the same time, Iran is believed to have provided the regime of Syrian President Bashar Assad with billions of dollars in economic aid and fuel over the past three years as Syria's civil war erupted.
Public grumbling grew. Prices for staples such as chicken and lamb climbed out of reach of many low-income Iranians. Late last year, Iranian riot police were deployed at key intersections in Tehran after sporadic protests flared.
That frustration led to the election of President Hassan Rouhani, who campaigned on economic reforms. Iranians blamed former President Mahmoud Ahmadinejad for mismanagement and corruption that many believe was at least as damaging to the economy as the West's sanctions.
The bleak conditions may have also forced Rouhani—backed by Iran's supreme leader Ayatollah Ali Khamenei—to back the nuclear deal struck Sunday in Geneva between Iran and the U.S., Russia, China, France, the U.K. and Germany.
Rouhani, in an address delivered this week on the occasion of his first 100 days in office, said the Iranian economy contracted 6 percent in the last year. That compares with a 4.7 percent decline in the U.S. economy during the Great Recession, which lasted from December 2007 to June 2009.Rouhani pledged to halt the recession by March of next year and reduce inflation to an annual rate of 25 percent by the end of next year.
The White House says the nuclear deal keeps in place "the overwhelming majority of the sanctions regime." Almost all of Iran's approximately $100 billion in foreign exchange holdings remains inaccessible or restricted by sanctions.
That means for the vast majority of Iranians, the deal will do little to alleviate the cost of daily life. Inflation hovers around 35 percent, pushing the price of goods ever higher. Officially, unemployment is around 13 percent, though that number is widely thought by experts to be much higher.
"Iran will continue to bleed financially," said risk consultancy Eurasia Group in a report.
But sanctions will be suspended on gold and precious metals, Iran's auto sector and petrochemical exports. Restrictions on oil exports will get no tighter, as they were slated to, and restrictions on insurance were loosened, which will help make it easier for Iran to sell the oil it can. The agreement also gives Iran's aviation industry a boost by allowing airlines to buy needed parts.
And, importantly, the deal began to restore some confidence in the Iranian economy after an extraordinarily dark period. The public reaction to the deal was largely positive, and the rial immediately gained about 3 percent against the dollar, according to money exchangers in Tehran.
Amin Naderi, who imports sportswear, has been shrinking his business for months in fear that the economy would continue to slide and fewer people would buy his product. Now, he says, the situation is looking brighter.
When—and whether—a brighter outlook will turn into real gains for Iranians, though, remains to be seen. Reza Ghazinouri, a former Iranian student activist now at the Washington-based human rights group United For Iran, says Iranians seem overwhelmingly happy with the deal and what it could mean for the economy. But with sanctions relief so limited, he worries hopes are too high.
"A very very small percentage of people are unhappy with this," he says. "The rest of the people are really happy. But they are hoping too much."
