MIDEAST MONEY-Iran weighs reform to stem currency crisis

* Authorities propose centralised currency exchange

* New system could resemble managed float of rial

* Government hopes to end influence of speculators

* But unclear if authorities can supply enough dollars

* Unofficial trade might continue at much weaker rate

DUBAI, Sept 12 (Reuters) - Iran is hoping that radical

reform of its currency market will help to stabilise the rial,

which has been badly battered by Western economic sanctions,

speculators and inconsistent government policy.

The rial's unofficial rate plunged to record lows around

25,000 to the U.S. dollar this week, less than half its value a

year ago, as Iranians rushed to convert their savings into hard

currencies. They fear the sanctions, imposed over the country's

disputed nuclear programme, will prevent the central bank from

preserving the value of the rial.

To combat the slide, authorities have proposed establishing

a currency exchange that would bring together major traders and

replace the small, scattered money changers which dot Iran's

cities.

The new system, if it takes effect, could be tantamount to a

"managed float" of the rial in which the central bank would not

fix the exchange rate but would buy and sell currency in the

market to ensure the rate did not become too volatile.

"What's important is that the price of currency is set in a

transparent market and competitive environment with the supply

and demand approach," Mahmoud Dodangeh, a board member of Iran's

National Development Fund (NDF), was quoted as saying this month

by the Iranian Students' News Agency.

But the proposal has run into heavy criticism from Iran's

private sector. Businessmen argue it would do nothing to solve

the country's underlying economic problems, including

double-digit inflation and near-total exclusion from the

international banking system because of the Western sanctions.

Asadollah Asgaroladi, a wealthy exporter of Iranian

pistachios, dried fruit and caviar, expressed doubts about the

new system at a meeting last week of the Tehran Chamber of

Commerce, and in subsequent media interviews.

The currency exchange "will create a new channel for

corruption", Asgaroladi told Fars news agency. "According to the

information that has come out so far, it seems that most of the

trades in this bourse will be on the part of the government."

HARD CURRENCY

The rial currently trades at two key rates: the government's

official "reference" rate, at which only a limited amount of

dollars is available from the central bank, and a much weaker

rate determined by an unofficial market, where the vast majority

of Iranians obtain their foreign currency.

In January the government tried to close the unofficial

market by announcing an 8 percent devaluation of the official

rate to 12,260 and saying it would stamp out black market

traders.

But the move backfired by alarming ordinary Iranians and

accelerating their scramble for hard currency, pushing the

unofficial rate even lower. In March, authorities backtracked

and said they would let unofficial trading continue.

The rial's slide threatens to push up inflation and fuel

capital flight from Iran. It has also inflamed political

divisions, with legislative foes of President Mahmoud

Ahmadinejad accusing his administration of foot-dragging and

worsening the crisis.

"If the government had launched the currency exchange last

year through the central bank, we wouldn't be witnessing a

currency shock in the market," Gholamreza Mesbahi-Moghaddam,

head of parliament's planning and budget committee, was quoted

as saying by Fars this week.

Authorities blame much of the rial's weakness on

speculators, and argue the new system would break their hold.

The exchange would be open to "certified" buyers and

sellers, according to government officials quoted in Iranian

media this month. Futures contracts - agreements to trade the

rial at certain prices on future dates - would become available

later on, letting traders lock in prices and ensuring stability.

Ordinary people in need of dollars, such as travellers and

students, would buy hard currency from designated banks at

prices determined by the exchange, Reza Azimi, director for

monetary and fiscal policies at the Ministry of Economics, was

quoted as saying by economic daily Donya-e Eqtesad.

"Currently, market factors do not determine prices," he

said. "A few people inside and outside the country have become

the decision-makers."

State media said the exchange might be launched at the end

of the current Persian calendar month, or Sept. 21. The scheme

seems to have replaced a previous plan, announced last month by

central bank governor Mahmoud Bahmani, to devalue the official

rate once again.

SCEPTICISM

It remains to be seen, however, whether the government will

go ahead with the plan for the exchange in the face of technical

challenges and scepticism from some in the private sector.

The NDF's Dodangeh said authorities hoped the price of the

rial on the new exchange would settle somewhere between the

current unofficial and official rates.

To ensure stability, he said, the government would provide

the exchange with an initial $5 billion of foreign currencies

drawn from the NDF, a body which invests in infrastructure and

is funded by oil revenues.

But to function effectively, the exchange will need to

persuade the mass of Iranians that it is producing fair rial

rates based on market supply and demand. Otherwise, people will

be reluctant to use the exchange-determined rates and continue

to buy and sell dollars through the black market.

"As long as there are multiple rates for the rial, they

can't establish the bourse" because there will be no confidence

in the values quoted by the exchange, a Tehran money changer

told Reuters by telephone, declining to be named because of the

political sensitivity of the issue.

Some Iranian businessmen argue the proposed exchange would

merely create a third rate alongside the official and unofficial

rates, Donya-e Eqtesad reported. These businessmen speculated

the unofficial rate might drop to 30,000.

Another big question is whether the supply of dollars in

sanctions-hit Iran would in the long term be large enough to

meet demand at the rates determined by the exchange.

At the end of last year, Iran had $106 billion of official

foreign reserves, enough to cover an ample 13 months of imports

of goods and services in normal times, according to the

International Monetary Fund.

But those reserves may now have started falling as the

economic sanctions hurt Iran's ability to export oil and make

financing its other foreign trade more costly. Analysts estimate

Iran's oil exports may have dropped by about 1 million barrels

per day from roughly 2.3 million bpd last year.

Nader Habibi, an economist at the Crown Center for Middle

East Studies at Brandeis University in the United States,

estimated the government now had about $50 billion to $70

billion of hard currency reserves remaining.

Some Iranian members of parliament and importers, including

Mesbahi-Moghaddam, told local media this week that the central

bank had for the last several weeks failed to supply enough

dollars to meet demand. This fuelled market speculation that the

central bank might be cutting back its supply because it was

concerned about a drop in its reserves.

Central bank chief Bahmani, however, insisted the official

exchange rate would remain available for use by importers who

needed dollars to buy essential goods.
