最新报道:The U.S. Treasury's 30-year bond auction in August 2025 recorded weak demand with a bid-to-cover ratio of 2.27, falling below the 10-year average amid persistent inflation, geopolitical tensions, and Federal Reserve policy uncertainty. Rising yields at 4.81% are increasing U.S. borrowing costs, potentially triggering a cycle of higher debt issuance and market instability. Analysts warn of amplified systemic risks from leveraged strategies and liquidity constraints, advising investors to hedge duration exposure through short-term Treasuries or TIPS while monitoring Fed policy shifts.
