Published by Zeb BhamThree Japanese government officials have intimated that plans to sell the yen would be impeded by US opposition.Speaking to Bloomberg on condition of anonymity, the officials said it would be difficult to launch an effective strategy to bring the yen lower without US support.Two of the officials also added that while the yen is currently trading near a 15-year high, it will be volatility, rather than the strength of the currency, that would be the determining factor in whether the government intervenes directly in the currency.In an interview with the news agency, Takahiro Mitani, president of the Government Pension Investment Fund in Tokyo and a former executive director at the Bank of Japan, said coordinated currency intervention, which helped to set a floor for the yen in 2000, would be unlikely."This time, Japan isn't the only nation having trouble, and the US and Europe also have a fire under their feet. In that environment, it's not easy for Japan to gain support," he added.For more information on foreign exchange treasury services and risk management, visit our Corporate FX site.
