澳大利亚10年期政府债券收益率周二触及15年高位，突破5%1。这一变化反映了全球债券市场的广泛上升趋势——美国10年期利率约为4.7%，较今年初上升近0.5%，30年期债券更是创近20年新高1。债券市场的压力源于政府债务规模的急剧扩张，美国国家债务已超过40万亿美元，澳大利亚联邦政府债务最近突破1万亿澳元1。与此同时，维多利亚州10年期债券利率攀升至5.55%1。
政府并非唯一的发债方。美国科技公司如亚马逊和微软约发行2400亿美元债券用于数据中心建设1，谷歌母公司Alphabet上月也发行了55亿澳元债券1。这种融资需求叠加政府大规模发债，进一步推升了全球利率水平。央行的工具受限，无法直接控制长期债券利率，仅能通过维持低通胀预期间接影响市场利率1。澳大利亚央行的通胀目标为2-3%1。美国财政部长斯科特·贝森特试图通过债券回购减少供应、降低市场利率1。
Australia's 10-year government bond yield reached a 15-year high, surpassing 5% this week, reflecting broader turbulence across global debt markets as governments issue record amounts of bonds 1. The United States 10-year yield stands at approximately 4.7%, up nearly 0.5% from the start of the year, while the 30-year bond has hit levels unseen in two decades 1. These movements mirror the scale of government indebtedness worldwide: the U.S. national debt exceeds $40 trillion, while Australia's federal government debt recently surpassed A$1 trillion 1.
The bond market upheaval extends beyond sovereign debt, as major corporations tap these elevated yields for capital needs 1. Tech giants including Amazon and Microsoft have issued approximately $240 billion in bonds for data center expansion, while Alphabet, Google's parent company, sold A$5.5 billion in bonds last month 1. Central banks face limited tools to manage the situation directly; the Reserve Bank of Australia cannot control long-term bond rates but can only indirectly influence market yields through expectations about inflation, which it targets at 2-3% 1. U.S. Treasury Secretary Scott Bessent has attempted to reduce market pressure by considering bond buyback programs to lower the available supply of bonds and ease upward pressure on yields 1.
