On 1 July 2012, the European Union’s sanctions against Iran kick in.  This includes European shipping insurers (who dominate the market) ending insurance on ships carrying Iranian oil.

20 June 2012, the Japanese Diet has passed a law that allows the government to cover Japanese tanker ships transporting oil from Iran.

The law was unanimously passed by the Upper house, and will provide up to $7.6 billion USD in coverage.  Many Japanese insurance companies expressed concern for providing enough insurance due to the warmongering by the U.S. and EU against Iran.

The government insurance policy goes into effect several days before the EU sanctions on 1 July.
