LONDON, March 3 (Reuters) - Gold fell 1 percent on Thursday as European Central Bank chief Jean-Claude Trichet said the bank will exercise "strong vigilance" over inflation, raising the prospect that it may lift interest rates as soon as next month.
Spot gold <XAU=> fell as low as $1,417.22 an ounce and was at $1,422.55 an ounce at 1508 GMT, against $1,434.49 late in New York on Wednesday. The metal fixed at $1,421.50 at 1500 GMT.
U.S. gold futures for April delivery <GCJ1> fell $15.50 an ounce to $1,422.20.
The metal had retreated from the previous session's record highs earlier with investors seizing a chance to take profits after the Arab League said a Venezuelan proposal to end conflict in Libya was under consideration. But prices still found residual support from unrest in the region.
Trichet said that inflationary pressures have increased over the last month, risks are to the upside and "strong vigilance" is required. His remarks pushed the euro <EUR=> sharply higher versus the dollar. [
]"This is the type of language that in previous rate hike cycles preceded a rate hike," said currency strategists at Action Economics. [
]Widespread low interest rates, which have knocked the appeal of other assets such as cash on deposit, have burnished gold's appeal in recent years, helping drive prices to record highs. [
]Euro zone interest rate and German Bund futures fell on Thursday after Trichet said it was essential to keep a firm anchor on inflation expectations. [
]VTB Capital analyst Andrey Kryuchenkov said while a number of factors were still supporting gold, including violence in Libya, any suggestion that interest rates were set to rise was likely to put pressure on the metal.
"Due to civil unrest in the Middle East/North Africa region, the downside is still limited," he said. "Yet (the ECB comment) is still important, as it gives you a sense of things to come. Rates will have to rise, and currency yields (will be) up."
LIBYA SIMMERS
An earlier retreat in risk aversion had already weighed on gold, pulling prices back from the record $1,440.10 an ounce they hit on Wednesday, after the Arab League said a Venezuelan proposal to end the Libyan conflict was under consideration.
Oil prices slipped sharply after the report, retreating further from the 2-1/2 year high they hit last week on fears the unrest in Libya would spread further across the oil-producing region. [
]Spot gold has risen by 10 percent in the six weeks since unrest in Tunisia and Egypt spilled into Libya, Yemen, Bahrain and, most recently, Oman and Iran.

Thursday's correction notwithstanding, the situation is still likely to underpin gold prices, as analysts are sceptical over the latest news.
"I doubt a Chavez-brokered deal would have much impact from a political perspective as he has little legitimacy in the international political sphere," said Cedric Chehab, head of commodities analysis at Business Monitor, a research group.
"In terms of risk, we expect any rise in tension to raise oil prices, which will likely see risk aversion rise, and result in lower commodity prices, particularly for those correlated to risk appetite and the industrial cycle such as base metals. Gold and silver would remain supported as investors continue to move into 'safe haven' assets," he said.
Silver <XAG=> fell 0.8 percent to $34.39 an ounce, shy of Wednesday's 31-year high at $34.96.
Platinum <XPT=> eased 0.5 percent to $1,836.24 an ounce, while palladium <XPD=> was up 0.3 percent at $818.97. (Editing by Anthony Barker)
