Global markets remained volatile as a retreat in U.S. Treasury yields helped Wall Street recover, while Asian equities traded mixed amid elevated oil prices, a strong dollar and concern over fiscal and geopolitical risks. Hong Kong's Hang Seng Index fell 2.7%, or 667 points, to 23,943, its lowest since July, while Japan's Nikkei declined about 0.9%. The 10-year Treasury yield briefly reached 5.34%, its highest level since 2002, before easing toward 5.25% after Federal Reserve Vice Chair Philip Jefferson urged patience. Futures markets reduced the implied chance of an October Fed rate increase to roughly 25% from 70% a week earlier. Brent crude remained above $102 a barrel and the dollar index stayed near 102, a 17-month high. Investors awaited September U.S. payrolls, with economists expecting 90,000 jobs, 4.1% unemployment and 3.2% annual wage growth. Corporate results also drove sharp stock moves, including gains for Accenture and Micron and a decline for Nike after its outlook disappointed.
