LONDON  - World shares steadied on Friday after selling in the tech sector triggered their biggest fall in over a month, while the yen slid to a two-week low as the Bank of Japan signaled its stimulus was staying in place.

It was set to be the second week of falls for MSCI's widely tracked world index, although Europe, which has been the star performer in the first half of the year, was trying to end it on an upnote.

London, Frankfurt and Paris climbed between 0.3 and 0.5 per cent and the euro, the pound and the Swiss franc rose against the dollar in the currency markets. 

Greece's 10-year government borrowing costs fell to their lowest in almost a month in bond markets as well, as euro zone finance ministers and the International Monetary Fund approved a long-delayed 8.5 billion euro lifeline for Athens, albeit keeping them hanging on for debt relief.

"The things that we were worried about at the start of the year which were French elections and potentially a Greek deal not getting done, we have had all the good news on that now," said State Street Global Markets' strategist Michael Metcalfe.

He said the dollar's rise for the week suggested markets had now priced in that positive news - France's new President Emmanuel Macron is expected to get a parliamentary majority at the weekend too - and were thinking where to go next.

The Japanese yen hit a two-week low against the dollar after the Bank of Japan left its mass money printing program unchanged, maintaining the contrast with the U.S. Federal Reserve, which signaled further tightening this week.

It was trading 0.3 per cent lower at 111.23 yen  per dollar, while the euro was buying $1.1173 compared with almost $1.13 earlier in the week.

The yen's drop helped Japan's Nikkei advance 0.7 per cent, narrowing its loss for the week to 0.3 per cent.

"The market was relieved that there was no mention of an exit strategy, at least for now," said Yoshinori Shigemi, global market strategist at JPMorgan Asset Management.

SUBMERGING MARKETS

MSCI's broadest index of Asia-Pacific shares outside Japan ended down roughly 0.85 per cent for the week though for emerging markets more broadly it was looking like being the worst week of the year so far.

Russian stocks steadied on Friday but have been hammered more than 4 per cent this week and the rouble  is down for a third straight week, on talk of increased Western sanctions and as oil prices have stumbled back again. 

Overnight, the Nasdaq led losses on Wall Street, dragged lower again by shares including Apple (.AAPL.O) and Alphabet (GOOGL.O) that tumbled on bearish analysts' reports.

The broader S&P 500 index fell 0.2 per cent and the Dow Jones Industrial Average slipped 0.1 per cent though future's prices pointed to a modest recovery later. 

"It was a brutal day for the tech sector once again as investors are increasingly more worried about the (Federal Reserve) tightening cycle and how that would put a number of firms in trouble," Naeem Aslam, chief market analyst at ThinkMarkets in London, wrote in a note.

The number of Americans filing for unemployment benefits fell more than expected last week, and better-than-expected business conditions numbers also bolstered the case for the Fed to continue raising rates after its second hike of the year on Wednesday.

Sterling added almost 0.2 per cent to $1.2775. On Thursday, it jumped to as high as $1.2795 on signs of a shift in the Bank of England's stance on keeping interest rates at record lows.

In commodities, oil remained subdued however on continued worries over rising U.S. gasoline inventories adding to already elevated global supply.

Global benchmarks Brent and U.S. crude hovered at US$47.34 and US$44.74 a barrel, on track for 2.4 and 2.8 per cent drops for the week respectively. It will also be their fourth consecutive week of falls.

The dollar's strength kept gold lat at $1,255 an ounce, failing to make up Thursday's 0.6 per cent drop. It is poised to close the week with a 1 per cent loss, its second weekly decline.
