SYDNEY, Aug 27 (Reuters) - Asian shares touched two-year peaks on Thursday in the wake of Wall Street's record run as cheap cash drove up big-cap tech darlings, although Sino-U.S. tensions caused caution to creep in as the session progressed.
MSCI's broadest index of Asia-Pacific shares outside Japan .MIAPJ0000PUS turned flat after earlier reaching its highest since August 2018.
Japan's Nikkei .N225 eased 0.4% from levels not seen since mid-February, and South Korea .KS11 fell 0.8% as a jump in coronavirus cases ended four days of rises. S&P 500 futures ESc1 dipped 0.2%, although that followed five straight sessions of gains.
Asian investors turned more circumspect because of the military face-off in the South China Sea, as Washington blacklisted 24 Chinese companies while Beijing reportedly test fired missiles into the area on Wednesday. markets globally are still focused on the endless liquidity being pumped out by central banks.
Federal Reserve Chair Jerome Powell is expected to outline a more flexible approach to policy on Thursday including a shift to targeting an average inflation rate around 2% that will allow rates to stay super-low for longer. with U.S.-China tensions seemingly not a major concern, the deluge of fiscal and monetary support remains the overriding tail wind for risk assets with large cap the beneficiaries," said Rodrigo Catril, a senior FX strategist at NAB.
The Dow .DJI ended Wednesday up 0.3%, while the S&P 500 .SPX climbed 1.02% and the Nasdaq .IXIC 1.73%. Gains were again concentrated in the tech majors with Netflix Inc NFLX.O surging 11.6% and Facebook Inc FB.O 8.2%.
The liquid largesse from central banks has kept sovereign bonds well supported even as stocks reach new highs. Yields on 10-year Treasuries US10YT=RR have steadied at 0.68%, after finding solid bids around 0.73%.
At the same time, the prospect of even more easing from the Fed has kept the dollar on the defensive. Against a basket of currencies, it was stuck at 92.921 =USD on Thursday and uncomfortably close to the recent two-year trough of 92.124.
The euro held at $1.1832 EUR= and near its recent top of $1.1965, while the dollar backed off to 106.02 yen JPY= from a high of 106.57 earlier in the week.
