LONDON, June 26 (Reuters) - Modest gains from Europe's main bourses relieved nervy investors on Tuesday, after the latest escalation in an increasingly global trade storm pummeled Wall Street and sent China into 'bear' market territory.
A 0.3 percent rise from the FTSE in London .FTSE and 0.4 percent gains from Frankfurt .GDAXI and Paris .FCHI was a welcome sight after another bumpy Asian session had extended a sell-off that has now wiped $1.5 trillion off world stocks. .T .SS
China's yuan had slumped to a near six-month low against the dollar, while 0.5-0.8 percent fall on big share markets .CSI300 .SSEC .SS left them down 20 percent from their January peaks, a threshold that defines a 'bear' market.
The dollar hovered near a 12-day low against a six-strong group of other top world currencies .DXY having drifted down versus the euro EUR=EBS , yen JPY= and pound GBP=D4 despite a modest uptick in U.S. bond yields. FRX/
"The sell off in risk assets has eased, but it is certainly not the last storm we are likely to see coming from that direction," said Societe Generale (PA:SOGN)'s global macro strategist Kit Juckes.
The tense atmosphere also kept metals on the defensive as financial markets worried about the wider global economic fallout of the U.S. administration's "America First' agenda.
U.S. Treasury Secretary Steven Mnuchin had ramped up the rhetoric again on Monday saying on Twitter that restrictions on investing in U.S. tech firms would apply "to all countries that are trying to steal our technology." Street had tumbled, with the S&P 500 .SPX and Nasdaq .IXIC suffering their steepest losses in more than two months, and the Dow Jones closing below its 200-day moving average for the first time since June 2016. .N
The so-called FAANG stocks, which have led momentum in U.S. stocks, were hammered too after having hit record intraday highs last week. Facebook FB.O dropped 2.7 percent, Amazon (NASDAQ:AMZN)
Asia then followed albeit in smaller scale. Tech-heavy indexes such as South Korea's KOSPI .KS11 and Taiwan's weighted index .TWII fell 0.45 percent and 0.55 percent, respectively.
Taiwan Semiconductor Manufacturing Co 2330.TW was down 1.8 percent, South Korean chipmaker SK Hynix Inc 000660.KS lost 1 percent and Chinese tech giant Tencent Holdings 0700.HK shed 0.3 percent.
"Unlike the seemingly spur-of-the-moment tweets by President Trump and the retaliatory exchange of tariffs, Washington's bid to protect intellectual property is an issue at the heart of a trade row between two powers battling for future global supremacy," wrote Yoshimasa Maruyama, chief market economist at SMBC Nikko Securities in Tokyo.
"It's turning out to be a long-term bearish factor for the financial markets, as the United States is unlikely to back down at least through its midterm elections (in November)."
CARS WARS
Another sign of the dust gradually settling in Europe was the first rise in European car shares in eight days. Carmakers are another likely target of U.S President Donald Trump's tariff plans.
The euro dipped back having reached a near two-week high of $1.1722 EUR= while the dollar was beginning to find some traction again against the yen JPY= . It was last at 109.67, having fallen to a two-week low of 109.365 yen. The yen often attracts safe-haven bids in times of political tension and market turmoil.
Brent crude oil futures LCOc1 were up 0.15 percent at $74.83 on uncertainty over Libya's capacity to deliver on exports commitments. Brent futures had fallen 1 percent overnight as receding investor risk appetite weighed on commodities. O/R
Oil prices were capped after OPEC and its allies on Friday agreed to increase global supplies, albeit modestly.
Trade concerns kept copper on the London Metal Exchange CMCU3 near a 2-1/2-month low of $6,702.5 per tonne brushed on Monday. Spot gold shed 0.1 percent to $1,263.62 an ounce XAU= .
