Monthly PMI Decreases After Seasonal Spike 

The Purchasing Managers' Index for Iran’s overall economy declined in the third month of the current fiscal year (May 22-June 21) after surging in the preceding month.
The first fiscal month (started March 21) typically sees a decline in economic activity every year as it starts with the Iranian New Year holidays, as businesses only have 15 working days. 
The latest survey of the Statistics and Economic Analysis Center of Iran Chamber of Commerce, Industries, Mines and Agriculture — the sponsor and coordinator of Purchasing Managers' Index reports in Iran — shows the index (known by its Farsi acronym Shamekh) settled at 54.73 in the month to June 21 from 56.17 registered in the previous month, indicating a 1.44-point or 2.56% decline.
