Finance officials from seven of the world's biggest economies have agreed to take rare coordinated action to weaken the Japanese yen. The yen surged to record levels following last week's earthquake and tsunami and the resulting nuclear emergency in Japan. The Finance leaders from the Group of Seven major industrialized nations made the decision during a phone conference today. The yen immediately dropped in value following news of the joint market intervention. Meanwhile, the Bank of Japan said it will pump an additional thirty seven billion dollars into Japan's financial system to stabilize money markets that have been shaken. The injection of money is the latest in a series of attempts by the Japanese central bank to ensure that financial institutions in disaster-stricken parts, the country do not run out of funds.
