* Asian stock markets : tmsnrt.rs/2zpUAr4 * Nikkei bounces after suffering steep losses last week * Flash PMIs to show impact of Delta on manufacturing * Dollar holds near 10-mth highs, awaits Powell take on tapering * Oil prices find support after worst week in 9 months SYDNEY, Aug 23 (Reuters) - Asian shares and oil prices bounced on Monday as a wave of bargain hunting swept beaten-down markets and China reported no new locally acquired COVID-19 cases for the first time since July. A raft of “flash” manufacturing surveys for August out on Monday will offer an early indication of how global growth is faring in the face of the Delta variant, with analysts expecting some slippage especially in Asia. Japan’s factory activity growth slowed in August, while that of the services sector shrank at the fastest pace since May last year, highlighting the toll from COVID-19 measures on the economy. “Following a strong V-shaped recovery, there are many signs of slower growth,” says BofA’s chief investment strategist Michael Hartnett. “The U.S. yield curve is at a one-year low, emerging markets are negative YTD and both copper and oil are down double digits from recent highs.” He expects negative returns for stocks and credit in the rest of this year and suggests investors own defensive quality. Concerns over China’s economy have only intensified in recent weeks, while Beijing’s regulatory crackdown on the tech sector delivered a double blow to markets. More than $560 billion was wiped from Hong Kong and mainland China exchanges last week as funds fretted on which sectors regulators might target next. Beijing is considering pressing data-rich companies to hand over management and supervision of their data to third-party firms if they want U.S. stock listings, sources told Reuters. The impact has been evident in MSCI’s broadest index of Asia-Pacific shares outside Japan which sank 4.8% last week. The sheer speed and scale of the fall left it oversold, helping it rally 1.4% on Monday. Japan’s Nikkei also bounced 1.8%, but that follows a 3.4% slide last week to its lowest since December. Chinese blue chips firmed 1.2% from a three-week low. Nasdaq futures and S&P 500 futures both rose 0.3%, while EUROSTOXX 50 futures added 0.7% and FTSE futures 0.5%. TAPERING TIME? The spread of the Delta variant also has the potential to upset the timing of the U.S. Federal Reserve’s tapering plans. Dallas Federal Reserve President Robert Kaplan, a well-known hawk, said on Friday he might reconsider the need for an early start to tapering if the virus harms the economy. That adds an extra frisson of uncertainty to Fed Chair Jerome Powell’s speech at Jackson Hole this week, which has had to be moved online because of pandemic restrictions. “Our base case is that the FOMC will announce a taper in September if the August non-farm payrolls is strong,” said Joseph Capurso, head of international economics at CBA. “We anticipate the taper will be implemented in October or November, though the recent increase in Covid infections and deaths in parts of the U.S. may give Powell pause.” That is in marked contrast to the European Central Bank which is under pressure to add more stimulus, giving the dollar a leg up on the euro. “Unlike the Fed, we do not expect the ECB to shift away from its ultra-dovish monetary policy stance,” said Capurso. “We expect EUR to decline to a low of $1.12 in Q1 2022, before gradually appreciating.” The single currency regained some ground on Monday to $1.1720, after losing 0.8% last week to touch 10-month lows at $1.1662. The dollar index was trading at 93.323 having hit a 10-month peak of 93.734 last week. The dollar has been more restrained against the Japanese yen at 109.89, which is benefiting from safe haven flows. Global growth jitters took a heavy toll on commodities last week, with base metals, bulk resources and oil all falling. Gold was steadier at $1,787, still sidelined after a one-day plunge earlier in August. Oil recouped some losses on Monday, after suffering its worst week in more than nine months as investors anticipated weakened fuel demand worldwide due to a surge in COVID-19 cases. Brent rose $1.24 to $66.42 a barrel, while U.S. crude added $1.17 to $63.31. Editing by Shri Navaratnam and Jacqueline Wong Our Standards: The Thomson Reuters Trust Principles.
