Ekonomiska sanktioner mot Iran : En undersökning av oljebranschens aktiemarknad efter hävda sanktioner mot Iran

Sammanfattning: As decided by the FN and UN, a set of sanctions against Iran’s nuclear development and human rights infringements have successively been implemented during the course of several decades, severely affecting the country’s trade and overall development. The industries most affected by these restrictions include the oil- and gas industries. The sanctions were removed on January 16th 2016, once more giving Iran the opportunity to trade freely with other countries. This quantitative event study uses data from the Iranian and American stock markets to examine whether there is a statistical significant change in the revenue of 30 oil companies from the two countries during a period of ten days surrounding January 16th. The result is then analysed using a t-test. The study shows that there is a statistically significant change in revenue for the Iranian oil companies, but not for the American. This is explained using the Efficient Market Hypothesis, previous research and external factors affecting the revenues of the companies and the overall movements of the stock market.
