It seems the market responded to negative signals from developments both at the domestic and international fronts, according to the Donyaye Bourse website.
The market partly reacted to fears spawned from unofficial reports that the government may eliminate allocation of subsidized currency for importing basic goods and pharmaceuticals.
Despite mounting pressure on the government to scrap the policy, the government insists on staying put over fears that removing subsidized forex may push up prices of essential goods and medicine and lead to frustration among the people, especially those at the lower end of the economic ladder, according to Financial Tribune.
The investors were mainly disheartened by the statements by deputy health minister, Iraj Harirchi, on Tuesday, warning about the potential impact elimination of the policy could on the struggling insurance and pharmaceutical sectors.
Most of the domestic pharmaceutical companies import raw material using subsidized currency. Each subsidized USD is worth 42,000 rials.
Following the rumors, stocks in food and pharmaceutical companies came under sell-off pressure.
Apart from the shares of small companies, there was a partial sell-off in some commodity stocks influenced by sharp falls in global markets on Monday.
Global markets were responding to another escalation in the US-China trade war. China allowed its currency to weaken against the greenback, prompting the US government to label China a currency manipulator.
