LONDON/TOKYO, Oct 18 (Reuters) - Global shares edged higher on Friday, spurred by a rally in Chinese stocks on latest policy steps to boost demand and as robust U.S. economic data this week continued to bolster investor sentiment.

MSCI's index of global stocks edged up a quarter of a percent , with tentative early gains for European stocks .

Mainland Chinese blue chips had closed up 3.6%, their biggest daily gain in eight sessions, after the country's central bank launched two schemes aimed at boosting stocks. Weak data on China's economy helped keep sentiment in check.

Investors remain alert to potential market volatility, with war in the Middle East still looming large and the U.S. presidential election fast approaching. Several so-called 'Trump trades' have gained momentum in recent days as markets shorten the odds of a potential Donald Trump victory.

Traditional safe haven gold hit a fresh all-time high on the day, breaking above the $2,700 mark for the first time.

Third quarter earnings from major companies next week could also help set the tone for markets, after mixed results from a string of U.S. and European blue chips in recent days.

"(Have we had) higher rates for too long? That is very much on people's radar. There's a bit of a worry about aggregate demand," said Ross Yarrow, managing director of U.S. Institutional Equities at investment bank Baird.

Payrolls data due on Nov. 1 is likely to be the next big test for sentiment on the U.S. economy, Yarrow added.

The U.S. dollar index hovered close to an 11-week high versus major peers on the day, dipping slightly to 103.67, after climbing to 103.87 on Thursday for the first time since Aug. 2.

Data on Thursday showed U.S. retail sales rose a stronger-than-expected 0.4% last month, while a separate report showed initial jobless claims had dropped.

The 10-year U.S. Treasury yield stood at 4.0966%, little changed from Thursday, when it jumped 8 basis points.

The European Central Bank cut rates by a quarter point on Thursday, as expected, and four sources close to the matter told Reuters that policymakers were likely to cut again in December.

The euro was broadly unchanged at $1.0836 after sliding to $1.0811 in the previous session, the lowest since Aug. 2.

Sterling gained 0.3% to $1.3043, after data showed British retail sales unexpectedly rose in September.

The Bank of Japan said on Friday it must focus on the economic impact of unstable markets and risks from overseas, suggesting the central bank was in no rush to raise interest rates further.

The dollar eased 0.2% to 149.86 yen , after jumping above the psychological 150 barrier overnight for the first time since Aug. 1.

Oil prices were headed for their biggest weekly loss in more than a month on worries of lower demand, despite slight gains on the day.

Brent crude futures and U.S. crude futures edged higher, to $74.63 and $70.91 a barrel respectively.
