TOKYO, Jan 13 (Reuters) - The dollar steadied on Wednesday as the rush to safe haven currencies such as the yen and the euro halted temporarily after Chinese authorities intervened heavily to stem the yuan's fall.
U.S. stock prices also managed to eke out gains for second day, helping to easing investor anxiety on the global economy, though gloom is still all over the news with oil prices hitting a 12-year low.
Traders are also not sure if the yuan and Chinese share markets are beginning to bottom out soon after their wild swings so far this year had many investors worried the Chinese economy may be losing momentum - beyond Beijing's control.
The dollar index edged up to 99.023 .DXY =USD from this week's low of 98.252 set on Monday.
Against the yen, the dollar fetched 117.80 yen JPY= , extending its rebound from a 4 1/2-month low of 116.70 yen touched on Monday.

"If the dollar/yen rises further, I would like to sell it into the rally," he said.
