The value of the Syrian pound on the black market sank to 1,000 to the dollar at some money changers Tuesday, marking a new record low for the nosediving currency.

The drop comes amid a spiralling liquidity crunch in neighbouring Lebanon, which has long served as a conduit for foreign currency entering the heavily sanctioned government-held areas of Syria.

One currency exchange office in the Syrian capital Damascus told AFP he was selling dollars on the black market for 1,000 pounds for the first time on Tuesday.

A specialised website put the volatile rate at 975 pounds to the dollar -- more than double the official rate of 434 Syrian pounds posted by the central bank on its website.

At the start of the war in 2011, the rate stood at around 48 pounds to the dollar.

In the Old City of Damascus, a trader who preferred not to give his name said everything from food to transport had become more expensive in recent weeks.

"Prices have doubled in the past two months," the trader said.

"Everybody prices their items according to the new dollar exchange rate" on the black market, he explained.

Syria analyst Samuel Ramani said the pound had fallen by 30 percent since anti-government protests erupted in Lebanon on October 17.

An economic downturn has accelerated since the protests started, and a liquidity crunch has become more acute in a country that has long served as an economic and financial lifeline for dollar-starved Syrian businesses.

As Western sanctions tightened on Syria during the war, many in the country have opened businesses in neighbouring Lebanon, stashed their money in its banks and used the country as a conduit for imports.

But Lebanese banks started introducing controls on dollar withdrawals over the summer, straining the supply of the greenback to Syrian markets.

"Lebanese banks are significant for Syria's economy as they give Syria back door access to the US dollar," he told AFP.

"Based on commentaries from Syrian businesspeople, it appears as if the economic crisis in Syria is even worse than that in Lebanon as a result of the protests," Ramani said.

In another part of Damascus, a 30-year-old working in a shop selling computers and mobile phones imported from Lebanon said the store had to increase all prices.

"In the end this is going to be reflected in the market and most people won't be able to pay according to the new prices," the young salesman said.

"We fear further collapse," he added.

Syria's eight-year civil war has battered the country's economy, and depleted its foreign currency reserves.

An array of international sanctions have targeted President Bashar al-Assad's regime and associated businessmen since the start of the war in 2011.

Authorities estimate that since 2011, Syria's key oil and gas sector has suffered some $74 billion in losses.

The United Nations estimates the conflict has caused some $400 billion in war-related destruction.

It has also killed 370,000 people and displaced millions more.
