Impact of Forex Rate Volatility on Prices

Over the past decade, goods and services in Iran suffered at least two bouts of price shocks following unprecedented volatility in the currency market due to foreign economic sanctions.
But apparently the impact on diverse industries varies in terms of both the pace at which prices are affected and the extent of price surge. Say, for example, how far the price of a product soars due to rise in forex rates. 
The Monetary and Banking Research Institute -- affiliated to the Central Bank of Iran - has examined the spillover effect of currency rate fluctuations on prices of goods and services in the domestic market. 
Drawing on prices of 2,369 products made by companies listed in the stock market during 2005-2018, and the Production Price Index reported for 734 other items by official bodies, the MBRI concluded that the goods were influenced mostly by currency rate fluctuations.
