NEW YORK, April 6 (Reuters) - The euro rallied on Wednesday ahead of an expected interest-rate hike in the euro zone, while the weaker dollar and safe-haven appeal drove gold to another record high.
The slumping greenback and geopolitical unrest earlier sent Brent crude to a fresh 2-1/2 year high above $123 a barrel before turning lower as some said its recent gains were overdone.
The euro climbed against the dollar to its highest in more than a year one day before the European Central Bank is widely expected to raise its benchmark interest rate by 25 basis points to curb inflation pressures.
The ECB has held rates at a record low 1.0 percent since July 2008. The Bank of Japan, on the other hand, is expected to keep interest rates low at its policy meeting on Thursday following last month's massive earthquake and tsunami, and the yen slid to an 11-month low against the euro and a six-month low versus the dollar. <ECBWATCH>
Among other commodities, silver rallied to a 31-year high for a third consecutive day. Inflation fears have boosted precious metals, as oil and corn prices reached new peaks in recent days. A weaker greenback also makes dollar-priced assets more affordable to holders of the euro and other currencies.
"It is unquestionable that the demand for precious metals derives from the devaluation of the leading currencies -- the dollar, the pound and the euro," said Angelos Damaskos, a fund manager at Sector Investment Managers.
The euro rose as high as $1.4350 <EUR=>, according to Reuters data, its highest since late January 2010. It last traded up 0.9 percent at $1.4342. Against the yen <EURJPY=R>, it was up 1.3 percent at 122.35 yen.
Spot gold <XAU=> hit a record $1,461.91 an ounce and was later up 0.3 percent at $1,455.34 an ounce. Silver <XAG=> rose as high as $39.75. Brent crude <LCOc1> was down 39 cents at $121.83 a barrel after hitting its highest level since August 2008. U.S. crude <CLc1> was slightly lower around $108.27.
STOCK MARKET CONSOLIDATION
Global equities gained on a generally brighter economic picture though U.S. stocks were little changed in the early afternoon before the start of earnings season next week.
Portugal added support after the battered euro zone peripheral economy successfully sold six- and 12-month treasury bills but had to pay a steep price in interest. [
]Emerging markets also rose, helped by renewed interest due to higher expectations for interest rates in developed markets. Shares of European banks rose after the successful Portuguese debt auction. [

"It's a consolidation week."
Pado said that earnings could push the S&P 500 to 1,385 by early May.
Data showing that German industrial orders soared above expectations in February brightened the outlook for Europe's top economy. Orders grew by 2.4 percent on the month, compared to the Reuters forecast for an increase of 0.6 percent. [
].Portugal sold a total of 1.005 billion euros ($1.43 billion) in 12-month and six-month T-bills, but yields rose sharply from last month's auctions.
The 12-month T-bill yield rose to 5.902 percent from 4.331 percent in the auction three weeks ago, while the yield on the shorter maturity rose to 5.117 percent from 2.984 percent in a sale in early March.
Demand, however, outstripped supply by 2.6 times for the 12-month t-bills and by 2.3 times for the six-month T-bills. (Additional reporting by Edward Krudy, Nick Olivari, Frank Tang and Barani Krishnan in New York, with Dmitry Zhdannikov in London; Editing by Jan Paschal)
