Market observers say less political tensions on the global scene in recent days has impacted gold coin prices, even though the drop in gold prices in international markets also is seen as a contributing factor.
According to Reuters, gold prices dipped more than 2% on Friday as hopes for a global economic rebound got a boost from stronger-than-expected US non-farm payrolls data, reducing demand for safe havens.
Referring to gold prices in international markets, Ebrahim Mohammadvali, head of TGJU, forecast some stability in gold prices in the coming weeks if nothing out of the ordinary happens.
"We expect a gram of 18-carat gold to remain in the vicinity of 7 million rials in the coming days."
In a talk with Radio Saham, Mohmmadvali stressed that gold prices in the domestic market are largely influenced by currency prices and less by trends in international markets.
