LONDON, June 29 (Reuters) - World stocks enjoyed a strong bounce on Friday with European shares recovering from a turbulent week as investors' fears of higher barriers to trade came closer to becoming reality.
MSCI's index of world stocks .MIWD00000PUS rose 0.6 percent by 1212 GMT, its strongest gain in three weeks, but its second quarter was still set to be in the red as investors priced in U.S. tariffs set to be implemented next week.
The U.S. administration is due to activate tariffs on Chinese goods worth $34 billion on July 6, likely prompting a tit-for-tat response from Beijing.
European stocks rallied strongly, with the pan-European STOXX 600 .STOXX up 1.1 percent and Germany's trade-sensitive DAX .GDAXI up 1.4 percent.
U.S. stock futures also extended gains, up 0.5 to 0.6 percent and recovering from a brief spike lower after Axios reported that U.S. President Donald Trump has repeatedly told aides he wants to withdraw from the World Trade Organization. was the latest sign of investors' heightened sensitivity to deepening divides over trade. Tariff disputes have already mauled assets from the Chinese yuan to European autos stocks, and wiped $1.75 trillion off the value of world stocks since June 12.
Investors pulled nearly $30 billion out of equity funds globally this week, the second-largest ever outflows according to Bank of America Merrill Lynch (NYSE:BAC), while U.S. equity funds suffered $24.2 billion of outflows as investors bet U.S.-led protectionism would backfire. GAIN, YUAN PAIN
The euro EUR= was set for its strongest day in a month after leaders at an EU summit reached an agreement on migration, rising 0.8 percent to $1.1658. The agreement eased a threat to German Chancellor Angela Merkel's ruling coalition over the issue. outcome of the summit tells us something about the severity of the situation," said Jan von Gerich, chief analyst at Nordea in Helsinki. "I'm not confident it will solve the underlying issues but there was a fear that the summit would fail and we could get a collapse of the German government, so that risk premium is being priced out."
While Asian stocks rose, the Chinese yuan suffered its worst month on record, losing 3 percent against the dollar in June as investors pulled money from a market likely to suffer from higher barriers to trade.
The yuan CNY=CFXS traded as low as 6.6441 to the dollar, its lowest since November, as investors speculated China may seek to devalue its currency to compensate for higher tariffs.
"We continue to believe that the yuan movements are largely reflecting EM FX movements, and are not a sign of a concerted effort to devalue," said BBH currency strategists.
Despite gains on Friday, the CSI300 and Shanghai Composite are the world's worst-performing major indexes this year.
In stark contrast to the yuan, the U.S. dollar was set for its strongest quarterly gains since Q4 2016, helped by the U.S. Federal Reserve's move to raise interest rates in June, and expectations of further hikes this year.
On the day the dollar index .DXY edged down 0.5 percent to 94.924 as the euro rose.
European bonds diverged, with the EU Summit migration agreement pushing Germany's Bund yields DE10YT=RR up while Italian 10-year government bond yields IT10YT=RR fell to a one-week low. yield on benchmark 10-year Treasury bonds US10YT=RR held steady at 2.8455 percent and the yield curve US2US10=TWEB flattened further to 32.17 basis points. Some investors see its flattening as a sign recession may be around the corner.
Intensifying trade tariff fears contrasted with a still strong picture of the global economy and robust company earnings growth.
"Our view for this year has been that asset markets would likely underperform the real economy as peaking growth momentum, tighter financial conditions, higher inflation and more volatility would act as a drag on valuations even as EPS trends remain solid," said Morgan Stanley (NYSE:MS) analysts.
Despite trade tensions, the STOXX 600 remained on track for its strongest quarter since Q1 2017, and Britain's FTSE 100 .FTSE was set for its biggest quarterly gain since 2010.
Oil prices extended their gains to fresh highs on a tighter market as U.S. sanctions against Iran threatened to remove a substantial volume of crude oil from world markets amid rising demand. crude LCOc1 rose 1.3 percent to $78.85 per barrel, while U.S. crude CLc1 held steady at $73.45 a barrel.
Emerging stocks .MSCIEF jumped 2 percent from a one-month low. The index was still set for its worst month since January 2016 as the rising dollar battered emerging economies, and outflows from EM debt and equity funds accelerated in June to $18 billion.
