LONDON, July 7 (Reuters) - Gold slipped 1 percent in Europe on Monday as the dollar firmed to a one-week high amid expectations the European Central Bank will not raise interest rates further and oil prices eased more than $2 a barrel.
Gold <XAU=> fell to $920.70/921.70 an ounce at 1021 GMT from $932.00/933.00 an ounce in London on Friday when the U.S. markets were closed for Independence Day holiday.
The precious metal hit good support at its session low just above $918, but could be vulnerable to further weakness.
"The euro is a bit weaker, the dollar is stronger and the oil price is slipping a bit," said Commerzbank analyst Eugen Weinberg. "But also we are seeing that the equity markets are in better shape."
"There has been a strong negative correlation between the gold price and the equity markets," he added. "Risk aversion has led to an inflow into gold, so higher equity markets could see a lower gold price."
With equities now see-sawing, any further recovery could pressure gold.
The dollar is also bouncing higher, striking a one-month high against a basket of currencies on Monday morning. [
]Investors were cheered by last week's better-than-expected U.S. jobs data, and are now looking ahead to comments this week from Federal Reserve Chairman Ben Bernanke.
A firmer dollar typically pressures gold, which is bought as an alternative investment to the U.S. currency. A stronger greenback also makes dollar-priced commodities such as precious metals more expensive for holders of other currencies.
Oil prices also weakened in response to a firming dollar, adding pressure to gold, which is often bought as a hedge against oil-led inflation.
Crude fell below $143 a barrel, although losses were limited by concerns about the ongoing dispute between Iran, the world's fourth largest oil exporter, and the West over the Islamic Republic's nuclear programme. [
]While in the short term weaker oil prices are pressuring gold, in the longer run near-record crude prices are seen as a major supportive factor for the precious metal.
"Oil prices at these levels should anchor precious metal investment demand as investors seek portfolio protection against rising global inflation expectations," said Standard Bank analyst Manqoba Madinane in a note.
In fundamental news, London-based ETF Securities said the amount of gold it holds to back its Physical Gold exchange-traded fund has risen 15 percent in the last week to a record 1.459 million ounces.
The rise reflected gains across its physically backed precious metals ETFs, with its platinum and palladium holdings also rising to new records and silver ticking up 1 percent. [
]Platinum group metals prices are also sliding, with platinum shedding 1.5 percent to a one-month low and palladium just under 1 percent weaker, as investors took profits after the metals' recent gains, amid fears demand may slacken.
The PGMs are chiefly used in the manufacture of autocatalysts. Investors fear that falling car sales as the U.S. ecoonomy falters could hit PGM consumption hard.
"Fears over weaker auto demand impacting PGM demand, as well as weaker gold prices, have pulled down platinum," said Fairfax investment bank analyst John Meyer.
"Despite the weaker pricing, producers remain under considerable pressure due to the power shortages in South Africa," he added.
Lonmin, the world's number three platinum producer, has reopened a smelter it closed last week for repairs, taking some support from platinum prices.
The company said it will lose 5,000-10,000 ounces of refined platinum sales due to the shutdown. [
]Spot platinum <XPT=> hit a low of $1,967.50 an ounce, its weakest level since June 5. It later recovered to trade at $1,977/1,997, down from $1,999.00/2,019.00 in London.
Platinum has lost 13 percent in value since hitting a record of $2,290 in March. The metal, also used in jewellery, had rallied after a power crisis in main producer South Africa disrupted mining and sparked fears of a supply deficit.
Spot palladium <XPD=> slipped to $446.50/454.50 an ounce from $450.00/455.00 an ounce, while silver <XAG=> dropped to $17.87/17.93 an ounce from $18.02/18.12 late in London -- well below an 11-week high of $18.46 hit last week.
