Feb 2 (Reuters) - Gold and silver prices dropped on Monday as increased CME margin requirements ?added to the selling pressure following last week's selloff sparked by Kevin Warsh's nomination as the incoming Federal ?Reserve chair.

Spot gold was 3.2% lower at $4,708.19 per ounce by 1008 GMT, recovering ?from nearly a 10% fall earlier in the session. Bullion ?shed more than 9.8% ?on January 30, in its sharpest one-day drop since 1983.

Gold has lost about $900 since hitting an all-time-high ?of $5,594.82 on January 29, erasing most ?of this year's gains.

U.S. gold futures for April delivery were down 0.3% to $4,730.40/oz.

Spot silver lost 3.4% to $81.65, recovering from a fall of 15% ?earlier on Monday. It has shed ?about 33% ?since notching up an all-time-peak of $121.64 last week.

The CME announced hikes in margins on its precious metal futures on January 30 and said the ?changes were set to take effect after market close on Monday.

"The increase in margin requirements makes holding speculative positions less appealing now and this will also force a lot on the retail side of the market who do not have the extra liquidity to sell positions," said Zain Vawda, analyst at MarketPulse by OANDA.

"It ?is definitely ?creating a sort of feedback loop where as prices drop, more traders will face margin calls leading to more selling and even lower prices," ?Vawda added.

The dollar index edged higher last week after U.S. President Donald Trump named former Federal Reserve Governor Warsh as his Fed chair pick, making dollar-priced bullion more expensive for buyers overseas.

While investors expect Warsh to favour rate cuts, they anticipate he will tighten the Fed's balance sheet, a move typically supportive of the dollar.

Barclays said in a note on ?Monday it expects rate cuts, fiscal expansion, quantitative easing, fiat debasement and de-dollarisation to likely keep investment demand firm for gold.

Spot platinum fell by 4.3% to $2,070.64 per ounce after hitting a record $2,918.80 on January ?26, while palladium shed 2.1% to $1,662.68.
