According to Masrour Barzani, the Kurdistan Region's oil revenue was previously 1 billion 179 million dollars a month, or 1 trillion 700 billion dinars.
KRG Prime Minister Masrour Barzani said on his official account on (X) that "the delay in exporting oil from the Kurdistan Region has hurt Iraq’s economy as a whole—over $25 billion in lost revenue to date."

If Masrour Barzani's statement is interpreted:
Oil exports from the Kurdistan Region were suspended on March 25, 2023. Since then, it has been one year, 9 months, and 10 days.
This means that the oil revenue of the Kurdistan Region was 25 billion dollars within one year, 9 months, and 10 days.
If we divide the $25 billion by that period, it is $1.179 billion per month, or 1 trillion 768 billion dinars monthly.
Although oil revenues vary according to the daily price, this interpretation is for the 25 billion dollars, for the period when oil exports were suspended, that is, from March 25, 2023, to today, as Masrour Barzani has mentioned.
