Asian shares sank on Tuesday, as worries about the Chinese property sector weighed on markets from Hong Kong to Australia, while Japanese investors sold chip stocks on their return from a holiday-extended weekend. Benchmark U.S. Treasury yields hovered near 16-year peaks and the dollar held close to six-month highs as traders braced for a Federal Reserve rate decision on Wednesday, in a week that also sees policy decisions from the Bank of Japan and Bank of England, among others. Japan's Nikkei tumbled 1.1% under the weight of big losses for chip-related stocks including Tokyo Electron and Advantest.
