TOKYO, Aug 7 (Reuters) - Asian shares steadied slightly on Wednesday as investors caught their breath from a searing week-long selloff, with steps taken by Chinese authorities to contain a sliding yuan helping calm fears of a full-blown Sino-U.S. trade and currency war.
MSCI's broadest index of Asia-Pacific shares outside Japan was up 0.05% in early trade after tumbling 8.26% in the previous eight sessions. Japan's Nikkei bucked the trend to slip 0.26%.
On Wall Street on Tuesday, the S&P 500 gained 1.30% and MSCI's broad gauge of stocks across the world rose 0.50%, its first gain in seven sessions.
The rebound came as the People's Bank of China took steps on Tuesday to stabilise the yuan with a firmer-than-expected fixing and a bond sale to signal that the authorities wished to stem the rout.
Comments from Larry Kudlow, director of the White House National Economic Council, also soothed sentiment. Kudlow said on Tuesday the Trump administration wants to continue trade talks with China and is still planning to host a Chinese delegation for talks in September.
The yuan had fallen sharply on Monday, going past the symbolic 7-per-dollar level, and prompting Washington to label Beijing a currency manipulator in a major escalation of the year-long trade dispute between the world's two largest economies.
In early Asian trade on Wednesday, the offshore yuan was flat at 7.0533 yuan per dollar, off Tuesday's low of 7.1400, its weakest level since international trading in the Chinese currency began in 2010.
Many investors believe Trump cannot afford prolonged instability in financial markets since his reputation was staked so closely on economic growth and the success of the U.S. stock market.
"Global financial markets have been shaken by concerns that escalating U.S.-China trade tensions, which now has triggered a currency war, would cool the world economy substantially," Masahiro Fukuda, investment director at Fidelity.
"While we cannot rule out the possibility of political negotiations leading to unexpected outcomes, we think it is unnecessary to worry about recession as various fiscal and monetary stimulus should support the economy of the two courtiers," he said.
Overall, however, market sentiment remained fragile and with no clear end in the trade standoff in sight, some investors expect a rocky session ahead.
Goldman Sachs said it no longer expects a trade deal to be struck before the November 2020 U.S. presidential election, while Morgan Stanley warned that more tit-for-tat tariffs could tip the world economy into recession by the middle of next year.
That rather grim backdrop supported safe-haven assets, with gold hitting a six-year high of $1,477 per ounce in early Wednesday trade. It last stood at $1.474.7.
U.S. bonds have also retained much of their gains made in the past week. The 10-year Treasuries notes yielded 1.695 percent, compared to above 2 percent just a week ago, as investors bet on another rate cut by the Federal Reserve in September.
In the currency market, the dollar was traded at 106.33 yen , down 0.13% from late U.S. levels, but off Tuesday's seven-month low of 105.52.
The euro stood flat at $1.1203. The Australian dollar fetched $0.67605, just a stone throw from its seven-month low of $0.6748 touched on Monday.
The New Zealand dollar was little changed at $0.6527 . The Reserve Bank of New Zealand is widely expected to cut interest rates for the second time this year, by 25 basis points to all-time low of 1.25 percent on Wednesday, to counter pressure on the economy from global trade disputes.
Oil prices also weakened, with global benchmark Brent crude slipping to seven-month lows, as trade tensions between the U.S. and China intensified worries about weakening world demand.
Brent crude futures fell 0.36% to $58.73 a barrel, near its low on Tuesday of $58.55, a trough last seen in early January. (Editing by Shri Navaratnam)
