China wobble knocks stocks, bitcoin eyes $10,000

By Jemima Kelly

LONDON (Reuters) - World stocks edged lower on Monday, led by a fall in Chinese share prices and a sell-off in South Korean tech stocks that kept risk appetite muted, while the euro hit a two-month high against the dollar on optimism around German coalition talks.

Away from the main markets, bitcoin's vertiginous ascent showed no signs of abating, with the cryptocurrency soaring to another record high just a few percent away from $10,000 after gaining more than a fifth in value over the past three days alone .

But those gains were not enough to pull up the MSCI world equity index , which tracks shares in 47 countries. The index was down 0.1 percent on the day.

In Asian trading, Shanghai shares <.SSEC> fell 0.9 percent to a three-month low, having already been on a shaky footing due to a rout in the domestic bond market and fresh moves to reduce risks in the asset management industry that may bring a sea change for banks. [.SS]

"The Chinese stock market drop is reminiscent of the selloff that we saw in the summer of 2015, and that is causing some investors to become cautious going into the thin year-end markets," said ING currency strategist Viraj Patel, in London.

The dollar fell a quarter of a percent against the yen, a currency that is traditionally sought at times of investor uncertainty. The dollar was trading at 111.27 yen , close to a 2-1/2-month low.

The euro climbed as high as $1.19965 , its strongest since mid-September, boosted after German Chancellor Angela Merkel - whose chances for a fourth term were plunged into doubt a week ago when coalition talks collapsed - was handed a political lifeline by the Social Democrats.

It has also been given a leg up in recent months by signs that Europe's economic recovery is gaining speed, with upbeat data from Germany lifting the single currency on Friday.

But it edged back to $1.1930 in European trading, flat on the day, with a Merkel ally saying on Monday that the "grand coalition" talks may not begin until next year, potentially prolonging the uncertainty in Europe's largest economy. [nL8N1NX1LC]

In Germany, the 10-year Bund yield dipped 1 basis point to 0.35 percent .

"There is optimism about the formation of a grand coalition in Germany, and economic surprise indices for the bloc are at an all-time high," said Antoine Bouvet, rates strategist at Mizuho.

"That means there could be more investment in Europe, driving the currency higher, and the corollary to that is for market expectations for ECB policy has to be more dovish."

TECH SHARES SLUMP

Earlier, Asian stocks retreated from a decade high, with MSCI's broadest index of Asia-Pacific shares outside Japan falling 0.7 percent.

The index had risen to its highest since 2007 on Thursday, with equity markets having enjoyed strong support this year thanks to corporate earnings rising on the back of an improving global economy.

Strength in tech shares had pushed the S&P 500 and Nasdaq to record highs on Friday, but observers noted that demand for tech-related products such as semiconductors could eventually slacken.

"Global sales of semiconductors expanded greatly in the third quarter. But demand could slow in the fourth quarter as a reaction to this sharp increase, and there are warning signs such as reversals in price trends," wrote Yoshimasa Maruyama, chief market economist at SMBC Nikko Securities in Tokyo.

Losses were limited though as expectations that OPEC and other key exporters will agree this week to extend production limits provided support.

Bitcoin surged almost 5 percent to trade as high as $9,721 on the Luxembourg-based Bitstamp exchange, before easing back to just below $9,500 in volatile trade.

The digital currency has seen an eye-watering tenfold increase in its value since the start of the year, and has more than doubled in value since the beginning of October.

"$10k is on the cards and bitcoin seems to be straining at the leash to reach it," said Charles Hayter, founder of cryptocurrency data analysis website Cryptocompare.
