Dollar extends gains versus yen, up most in nearly 2 years
The dollar was up 3.1 percent at 85.63, on track for its biggest daily gain in nearly two years. It fell below to a 15-year low beneath 83 yen overnight, which prompted the Bank of Japan to begin selling yen in the market for the first time in six years. The euro was also up 2.9 percent at 111.10 yen, its biggest one-day gain since February 2009.
