MANILA, July 22 (Reuters) - Gold fell on Wednesday for a seventh session in eight, reflecting sustained downward pressure on the metal days after its steepest drop in almost two years, with more losses seen ahead as the demand outlook dims.
A looming hike in U.S. interest rates has dented gold's appeal as an investment, encouraging more sellers in the market after Monday's 4-percent rout. Holdings in top gold fund SPDR Gold Trust dropped further, marking their lowest since 2008.
"The long-term downtrend is still in place and more people are selling," said Mark To, head of research at Hong Kong's Wing Fung Financial Group.
"We can't see any bullish factor. Inflation is well contained and we don't see a systemic crisis that might push people to buy gold."
Spot gold XAU= fell 0.7 percent to $1,093.71 an ounce by 0610 GMT.
It touched a session low of $1,090.55, just shy of Monday's trough of $1,088.05 - its lowest since March 2010 - following a selloff exacerbated by huge volumes traded on the Shanghai Gold Exchange.
The Shanghai rout happened after investors dumped more than $500 million worth of bullion in New York in four seconds during the early Asian trading hours, when typically only tens of contracts of gold are traded. ID:nL1N10203C
U.S. gold for August delivery GCcv1 was down 0.8 percent at $1,094.20 an ounce, after falling as much as 1.3 percent, marking its 10th consecutive session of losses.

"The next price target may be $1,000. That's a sensitive level but it would not be surprising to see a test of the power of that support," said To.
Holdings in SPDR Gold Trust GLD , the world's largest gold-backed exchange-traded fund, fell further to 22.17 million ounces on Tuesday, the lowest since August 2008.
"Gold and by association, the precious metals complex, has done itself no favours ... over the last couple of days, and a market that was already in the doldrums, will find it hard to recover any lustre in the near future," wrote David Govett, head of precious metals at broker Marex Spectron.
Spot platinum XPT= was down almost 1 percent at $969.20 an ounce and palladium XPD= fell a similar degree to $620, both trading near multi-year lows. Silver XAG= eased 0.5 percent to $14.75 an ounce.
