An official with Iran's biggest state-owned Melli Bank told Reuters savings had declined by an unspecified amount, although he said this was a temporary phenomenon and that they would recover once the uncertainty over Trump's decision passed.
"When there is political uncertainty, its psychological impact on people causes a drop in savings. But it will pass after Trump's deadline," the official said before the announcement, declining to be named.
Trump said on Tuesday he would quit the deal and impose "the highest level of economic sanctions".
A senior Iranian central bank official said conditions within the banking system had deteriorated in the past year, and "we have still not passed the danger zone" but added that the central bank had "all the measures ready to prevent any crisis".
Officials with other leading lenders, Saman, Pasargad and Middle East Bank declined to comment.
The loss of confidence both reflects and contributes to wider problems threatening pragmatist President Hassan Rouhani in Iran's faction-ridden clerical establishment: investment has dried up as banks limit lending, growth is slowing and unemployment is at a record high, exposing Rouhani to growing criticism from hardliners.
"I am worried about a war," said Mina Abdelsalehi, 61, a retired teacher in Tehran. "I have changed all my savings into gold coins that I can cash easily if anything happens."
The rial currency lost close to half of its value in the six months to April in anticipation of a tougher U.S. approach, forcing Tehran to ban domestic foreign exchange transactions and limit foreign currency holdings to $12,000.
This failed to stop Iranians trying to buy hard currency on Tuesday, promoting a further slide in the rial, according to a foreign exchange website.
"Prices are going up almost every hour," said Ali Rasti, 45, owner of a real estate agency in Tehran. "People are worried and prefer to keep their money at home."
A separate Iranian banking official also said Iranians had taken out money. "Fearing a war and more sanctions, many Iranians have withdrawn their cash from banks," he said.
Mohammad Reza Pourebrahimi, head of parliament's economic committee, was quoted by the semi official ISNA news agency in March as saying capital outflows had been $30 billion in recent months. The International Monetary Fund said Iran's reserves were at nearly $112 billion in 2017/18.
DASHED HOPES
Iran had struggled to reap the benefits from the accord, which lifted international sanctions on the central bank and lenders in 2016 in return for curbs on its nuclear programme, but left U.S. restrictions in place to assuage fears it would benefit hardliners like the Revolutionary Guards (IRGC).
The IRGC, which reports directly to Iran's Supreme leader Ayatollah Ali Khamenei, controls vast segments of the economy including some banking interests as well as everything from ports management to telecommunications.
Iranian banks re-established relationships with more than 200 international counterparts, but any business active in Iran has to ensure there are no ties with IRGC interests to avoid fines or bars on trading in the United States.
"Money is moving but not as freely as governments had hoped," said Justine Walker, head of sanctions policy with trade association UK Finance, saying complications had multiplied since Trump became president. Euro transactions were taking place, she said, but sterling payments "remain challenging".
Sources involved in transactions said they rarely exceeded 200 million euros ($240 million) due to difficulties with clearing payments.
Nigel Kushner, chief executive of British law firm W Legal, said his clients exporting consumer goods to Iran had reported a 50 percent drop in purchases over the past two months. "There is a risk of further (bank) liquidity concerns," he said.
George Bennet, managing partner of financial services advisory firm OSACO Financial, which is active in Iran, said European lenders still in Iran were already nervous and limiting transactions to their largest and most valuable customers.
"The larger of the European banks currently doing business, which themselves are not large, with Iran will pull out of the market altogether," he said, when asked about the impact of the U.S. withdrawal.
OTHER CONSTRAINTS
Rouhani gambled on attracting foreign investment to help raise living standards but a raft of deals including plane purchases have been already been delayed.
FATF, a global group of government anti-money-laundering agencies, has kept Iran on its blacklist, adding to wariness by Western banks with dealing with Iran due to reputational risks.
Rouhani has struggled to reform the banking system, which, with 30 banks and other credit institutions, is more fragmented than those of other emerging markets and heavily burdened by bad loans.
Finance sources have estimated outstanding loans at around $283 billion and non-performing loans (NPLs) were estimated to have reached 12.5 percent in 2017 by US-based financial industry body the Institute of International Finance (IIF).
The latest official figure, 11.7 percent in 2016, equates to more than $30 billion. Some finance sources say NPLs could be even higher at close to 15 percent.
A textile factory owner in Mashhad said the government wanted to improve the economy but could not support business.
"How can I run my business when the dollar exchange rate is rising and I cannot get loans from the banks because of the high rates?" he said on condition of anonymity, explaining he had laid off around half his 65 employees to try to stay afloat.
"I am not sure how long I can keep the factory open."
