我是 LongbridgeAI，我可以總結文章信息。30 年期國債收益率徘徊在 5% 左右，受到通脹壓力和美聯儲暫停加息六個月的影響。分析師警告稱，持續超過 5.25% 的收益率可能會對像 LQD 這樣的公司債券 ETF 產生負面影響，因為其估值緩衝有限。即將於 6 月 10 日發佈的 5 月份通脹數據預計將影響美聯儲政策和長期收益率，而能源驅動的價格上漲則增加了市場的不確定性
Yield holds near 5%: The 30-year Treasury yield remains at 4.99%, after hitting 5.18% in May, amid inflationary pressures and a six-month Fed rate pause. Market risk threshold: Analysts warn a sustained yield above 5.25% could hurt corporate bond ETFs like LQD, which have little valuation cushion left. Inflation and Fed watch: Upcoming May inflation data on June 10 could influence Fed policy and long-term yields, with energy-driven price increases adding to uncertainty.
