NEW YORK/LONDON, March 30 (Reuters) - Gold prices pared gains on Wednesday as the metal struggled to rise toward all-time highs, weighed down by profit taking amid an initial decline in crude oil prices and technical weakness.
Bullion, which has dropped in each of the past four sessions, was also pressured by signs of monetary tightening by the U.S. Federal Reserve and the European Central Bank and nervousness ahead of Friday's U.S. nonfarm payroll report.
"Some investors may have been spooked by oil's decline and liquidated their positions in gold, as they have been trading oil and gold in pairs," said Phillip Streible, senior market strategist with MF Global's Lind Waldock unit.
Earlier in the session, gold and oil fell sharply in tandem after data showed swelling crude inventories. However, gold remained about $10 below its session high even as U.S. crude futures recouped most of their losses.

Spot gold <XAU=> gained 0.2 percent to $1,418.65 an ounce by 12:05 p.m. EDT (1605 GMT), having earlier touched a high of $1,430. U.S. gold futures for April delivery <GCJ1> rose 0.2 percent to $1,418.80.
Bullion's failure to capitalize on new record highs on recent strong volume suggested some investors are skeptical about the metal's investment appeal, analysts said.
A Reuters poll showed that gold's decade-long price rally, which took the metal to record highs last week, looks set to plateau in the second quarter as more downside risks for bullion emerge. [

Silver <XAG=> climbed 0.6 percent to $37.30 an ounce, sending the gold/silver ratio to below 38, the lowest level since 1983.

"Recent (silver) trading has been driven also by technical and momentum trading, rather than the fundamentals," said Daniel Major, an analyst at RBS.
Industrial demand for silver is set to rise to 665.9 million ounces by 2015 from $487.4 million ounces last year, metals consultancy GFMS said in a report prepared in conjunction with the Silver Institute. [
]MONETARY TIGHTENING IN FOCUS
Bullion hit a record $1,447.40 an ounce last week, after months of unrest across North Africa and the Middle East, with violence continuing to simmer in Libya, Bahrain, Syria and Yemen. [
]While this is limiting any correction in the gold price, the precious metal has struggled to eke out fresh gains as financial markets digest hints from the euro zone and U.S. authorities they may be set to tighten historically loose monetary policy.
"Gold players are anxiously waiting for policy signals from the U.S. and to see what the ECB (European Central Bank) actually does next week in its monthly meeting," said Credit Agricole analyst Robin Bhar.
"It would take an extraordinary event for the ECB not to hike, and in the U.S. tightening rather than keeping this accommodative bias (is likely). Those two factors do put a non-interest bearing asset like gold at a disadvantage."
Platinum <XPT=> gained 1.3 percent to $1,757.60 an ounce, while palladium <XPD=> was flat at $748.50.
