周五亚洲时段美债涨势加快，美国科技股抛售推动投资者涌向美国政府债券这一避险资产。
A rally in Treasuries gathered pace in Asia on Friday as a selloff in US tech stocks drove investors to the safety of US government debt.
美债收益率全线下跌至少4个基点，延续纽约时段的跌势。澳大利亚和新西兰债券跟随走势，两国基准10年期国债收益率均下跌逾5个基点。
Treasury yields dropped at least four basis points across the curve, extending declines from the New York session. Australian and New Zealand debt tracked the moves, with yields on the respective benchmark 10-year notes falling more than five basis points.
科技巨头Alphabet Inc.等公司业绩令人失望，强化了市场对人工智能交易可持续性的怀疑，避险情绪因此升温。10月以来基准美债收益率已下跌约40个基点，有望录得自2月以来首次月度下跌。
The flight to safety gained momentum after disappointing earnings from tech giants such as Alphabet Inc. reinforced doubts about the sustainability of the artificial intelligence trade. Benchmark Treasury yields have dropped about 40 basis points in October to head for their first monthly decline since February.
“债券早盘上涨，本周科技股财报出炉后又掀起一轮避险潮，”国民澳洲银行悉尼利率策略主管Kenneth Crompton表示。
“Bonds are rallying this morning with another safe-haven swoon after the tech results this week,” said Kenneth Crompton, head of rates strategy at National Australia Bank in Sydney.
