Asian share markets faced a testing time on Monday after Wall Street suffered its worst starting week in history and doubts over Beijing’s policy choices sent investors into the arms of the safe-haven yen and sovereign bonds. Indeed, currency markets were already seeing wild swings with the South African rand (ZAR=D3) collapsing over 10 percent at one stage. MSCI’s broadest index of Asia-Pacific shares outside Japan lost 0.6 percent, led by a 1.7 percent dive in Australian stocks (.AXJO).
