LONDON, Aug 2 (Reuters) - The dollar index hit a three-month low on Monday, hurt by worries that the U.S. economy's recovery is losing steam, while the high-yielding Australian dollar reached a three-month high, buoyed by a rise in equities.
The dollar has been hobbled by concerns over the U.S. economy after recent economic data undershot market expectations, while European numbers and many company results have been stronger -- keeping investors buying riskier assets.

Analysts said the perceived better risk sentiment outside of the United States was unlikely to be maintained if the world's biggest economy continues to underperform.
"We're seeing a disconnection as U.S. data stays weak yet risk appetite is strong. Weak U.S. data will translate into risk aversion at some point," said Tom Levinson, fx strategist at ING.
The dollar index, which measures the greenback's value against a basket of currencies, hit a three-month low of 81.354 .DXY, dipping below support near 81.44, which is roughly a 50 percent retracement of its November to June rally.
"A close below the 50 percent retracement level would open up a move to the 200-day moving average at 80.70. There is slight potential for further dollar weakness," said Michael Hewson, analyst at CMC Markets.
