LONDON, Sept 11 (Reuters) - World stocks rose for the sixth straight day on Wednesday and bond prices fell as investors unwound safety bets, encouraged by hopes of a resolution to the Sino-U.S. trade standoff and signs Europe may be preparing to ease budget spending rules.
Higher-risk assets such as equities and emerging markets rose almost across the board at the expense of safe-haven plays such as gold and bonds, as political risk appeared to ease in Britain, Italy and Hong Kong.
U.S. President Donald Trump's firing of hawkish national security adviser John Bolton was also seen as a positive, as it could potentially lead to an easing of tensions with Iran.
There are hints China will go full-throttle with growth stimulating measures following a raft of dismal data: having already eased banks' cash curbs, it has now scrapped quota restrictions on two inbound investment schemes in order to lure more foreign capital.
Investors are also awaiting the European Central Bank's meeting on Thursday at which it is expected to cut interest rates and unveil more bond buying, though policymakers' comments have recently raised doubts about the extent of stimulus that could be delivered.
"We're seeing yields backing up and safe havens and defensive equities underperform so we are seeing a bit of rotation. I don't think it's a structural shift, it's just that markets went too far and too soon, and we are seeing alleviation of that move," said Justin Onuekwusi, a fund manager at Legal & General Investment Management.
"The market is being driven by two extremes: one if we get further deceleration in trade, the probability of recession becomes quite high. But if we get a (Sino-U.S. trade deal) we could see confidence coming back," he added.
By 0830 GMT, MSCI's world equity index was up 0.3% following 0.5-1.5% gains across Asian bourses, including Tokyo Seoul and Hong Kong while a pan-European equity index rose 0.7% to five-week highs.
Futures indicate a flat open on Wall Street however , as share markets come under pressure from sharply higher U.S. Treasury yields.
Currency markets too reflected the risk-on mood, the dollar strengthening to a six-week high against the yen and 0.25% versus a basket of currencies. The British pound hovered just off six-week highs of $1.2385 hit earlier in the week.
The yen had rocketed towards a 2019 high in August as investors fretted about recession and market selloffs. Forex traders often buy the yen in times of uncertainty because of Japan's vast current account surplus and because Japanese investors usually bring money home when global markets tank.
But since the start of September it's fallen almost 2%.
"Yen weakness has been reinforced overnight by speculation that China will implement further measures to ease the negative economic impact from the trade war with the U.S.," MUFG analysts told clients.
Broader risk appetite fed through into gains for the Australian dollar, which rose 0.1%. Emerging currencies touched the highest since mid-August, according to an MSCI index .
Expectations the ECB will push interest rates deeper into negative territory have weighed on the euro, which has shed 3% since June.
But some policymakers have played down the prospect of sizeable asset purchases, and analysts cited a report that the ECB may delay quantitative easing and tie it to upcoming economic data.
That alongside signs Germany might eventually ease its long-held opposition to loosening budget rules, lifted bond yields across the bloc.
Finance Minister Olaf Scholz said on Tuesday that Germany could counter economic crises by injecting billions of euros into the economy. That lifted Germany's 30-year borrowing costs above zero for the first time in over a month while 10-year bond yields too are 20 basis points above record lows reached a week ago.
"The recent market moves illustrate that expectations maybe went a bit too far, and with the ECB hawks on parade, doubts were raised on whether the ECB could meet the high expectation," Jan Von Gerich, chief analyst at Nordea, told the Reuters Global Markets Forum.
"I am still expecting a full package of measures."
U.S. 10-year Treasuries yields also rose back towards a one-month high of 1.745% hit on Tuesday while Japanese 10-year yields approached one-month high of minus 0.200%.
The U.S. Federal Reserve is expected to deliver a 25 basis-point cut when it meets next week, though any hopes of a 50 bps cut have receded almost to zero.
On commodity markets, Brent futures hovered near their strongest in six weeks, despite small losses on Tuesday after the sacking of Bolton as it raised the prospect of Iranian exports returning to the market.
Gold prices snapped a four-day losing streak to rise around 0.3% but they have shed more than 4%, or over $60, since scaling a more-than six-year peak of $1,557 on Sept. 4.
