I really love macroeconomics, especially when it's about political themes. This Sunday 1 July 2012 Europe is starting a full oil embargo against Iran. It will not import oil from Iran.
Iran will lose 30% of its exports, while Europe loses 6% of its oil imports. This means tight supply of oil and a rising oil price (8%) as a consequence.
Oil imports into Europe can be found here: http://ec.europa.eu/energy/observatory/oil/import_export_en.htm
You can see that the biggest oil exporter to Europe, namely Russia (30%) will be the ultimate winner here. That's why investing in Russia is a good thing. For example: Gazprom. I discussed this stockpick here.
The oil embargo also increases the chance of Iran blocking the Strait of Hormuz, which will be benefiting the oil price and the Baltic dry index.
