Coin World news: Jane Foley, an analyst at Rabobank, said speculation that Japanese authorities may intervene in the yen by taking advantage of thin trading volumes on Friday in the U.S. is gaining momentum. In fact, Japanese authorities are not taking any action, which may be even more surprising. She said that further intervention appears to be inevitable, but intervention alone is unlikely to be sufficient to change the market’s negative view of the yen. The yen’s weakness is partly driven by the stronger U.S. dollar, but a rise in Japan’s stock market may prompt foreign investors to strengthen their hedging measures against the risk of further yen depreciation.
