NEW YORK, July 21 (Reuters) - The dollar retreated from a three-month high against a basket of currencies on Tuesday on mild profit-taking, while commodity-related currencies stabilized on a pause in gold's recent sell-off.

The dollar is expected to strengthen again in the coming weeks as traders anticipate the U.S. Federal Reserve will raise interest rates by year-end.

"The tension is fading on the euro down there," said David Rodriguez, quantitative strategist at FXCM in New York. "The dollar is still in control."
The euro EUR= was up 0.4 percent at $1.0873 after retesting a near three-month low of $1.0808 set on Monday. It is down 2.3 percent so far this month.
The greenback was firm at 124.34 yen JPY= , hitting a five-week high of 124.48 late in the Asian session.
The dollar index .DXY dipped 0.2 percent to 97.782 after touching a three-month peak at 98.151 earlier Tuesday.
The pullback in the dollar was mitigated by a rise in U.S. Treasuries yields US10YT=RR on expectations of a Fed rate increase and heavy supply of corporate bonds. US/ USC/
Meanwhile, the gold market stabilized after a steep drop on Monday, helping commodity-linked currencies including the Canadian, New Zealand and Australian dollars.

RBA's view differed from New Zealand's, where Prime Minister John Key on Monday offered the currency some verbal support.
The Aussie dollar was up 0.2 percent at $0.7383 AUD= , while the kiwi rose 0.7 percent to $0.6604 NZD= .
Spot gold prices XAU= held above a five-year low on Tuesday but there was anxiety that their fall would resume toward $1,000 an ounce due to sluggish Chinese demand and a possible Fed rate hike that would raise the appeal of the dollar.
