The dollar remained near its highest level in six months at the beginning of Wednesday's session, as concerns about China and global growth affected risk appetite, while the yen approached its lowest level in ten months.

The yen recorded 147.66 yen to the dollar in the early hours of Asian trading, which is slightly lower than 147.8 to the dollar, which was the lowest level since the fourth of November, which it touched overnight. It had been hovering around the 145 level against the dollar during the past few weeks, which pushed traders into a state of cautious anticipation for signs of intervention.

Against a basket of other major currencies, the dollar index rose 0.067 percent to 104.80, a level not far from the six-month high of 104.90 that it touched overnight.
