LONDON, April 14 (Reuters) - Gold eased on Thursday as the dollar extended its biggest one-day rally in over a month, though losses were limited by a retreat in oil prices and European stocks, which supported interest in the metal as an alternative asset.
The precious metal has eroded all its early gains for the week after touching a three-week high at $1,262.60 an ounce on Tuesday, under pressure from a rebound in the U.S. currency.
Spot gold XAU= was down 0.2 percent at $1,240.76 an ounce at 0936 GMT, while U.S. gold futures GCv1 for June delivery were down $5.70 an ounce at $1,242.60.
The metal has steadied after its biggest quarterly rise in nearly 30 years, driven by a retreat in expectations that the Federal Reserve will push ahead with rate hikes this year.
That would lift the opportunity cost of holding non-yielding assets, while boosting the dollar, in which gold is priced.
"The big shock for the gold market, and commodities markets in general, was the big move higher in the dollar yesterday," Danske Bank analyst Jens Pedersen said. "Overall I see gold prices remaining fairly stable around current levels."
"What risks the gains in the gold market this year reversing is the Fed starting to push ahead with rate hikes, but I don't see them hiking before September," he said. "If the recent slide in the dollar is sustained, gold will keep these gains."
The dollar rose another 0.2 percent versus a currency basket as improved risk sentiment led investors to trim positions in low-yielding currencies like the yen and the euro. FRX/
European stocks eased 0.2 percent, however, weighed down by a half-percent drop in oil prices as the International Energy Agency trimmed its forecast for demand growth and on signs that a producers' meeting this weekend will not yield a concrete plan to reduce oversupply. .EU O/R
Bullion-backed exchange-traded funds have seen outflows of late following sharp inflows earlier in the year. Holdings of the world's largest gold-backed ETF, SPDR Gold Shares GLD , fell 5.05 tonnes on Wednesday to their lowest in a month.
"Gold is weakening on a recovery in investor risk appetite. The sharp (equities) rally and the levelling off of gold-ETF demand recently argue for some period of price consolidation," HSBC said in a note.
"It is possible this consolidation turns into liquidation, but we think any continued sell-off, though likely, should be modest."
Among other precious metals, silver XAG= was down 0.3 percent at $16.14 an ounce, after reaching its highest since late October the previous day. Platinum XPT= was down 0.4 percent at $990.50 an ounce, while palladium XPD= was down 0.4 percent at $540.55 an ounce.
