美债专题跟踪（2025.12.1-2025.12.5）：日央行释放加息信号触发美债抛售，10年期美债收益率大幅上行

Report Industry Investment Rating No relevant content provided. Core Viewpoints - The 10-year US Treasury yield is expected to continue to rise slightly this week due to factors such as the risk of a "hawkish rate cut" by the Fed, market concerns about inflation control under a potential radical rate cut scenario, and the ongoing fermentation of the Bank of Japan's December rate hike expectation [7][8]. Summary by Directory 1. Last Week's US Treasury Yield Trend Review - In the week of December 1, 2025, the 10-year US Treasury yield increased significantly. On Monday, the Bank of Japan's clear rate hike signal and a large number of corporate bond issuances led to a 7bp increase to 4.09%. On Tuesday, it remained unchanged at 4.09%. On Wednesday, the unexpected decrease in US private sector employment in November pushed it down 3bp to 4.06%. On Thursday, factors like low initial jobless claims and a record high in US government debt led to a 6bp increase to 4.11%. On Friday, a rebound in the December Michigan consumer confidence index caused a 3bp increase to 4.14%, a 12bp increase compared to November 28 [1]. 2. Short-Term Trend Outlook - This week, the 10-year US Treasury yield may continue to rise slightly. The market has fully priced in a 25bp rate cut by the Fed in the December meeting, but the risk of a "hawkish rate cut" is high. Concerns about inflation control under a potential radical rate cut by "shadow chairman" Hassett and the Bank of Japan's rate hike expectation will also push up the yield [7][8]. 3. 10Y - 2Y Yield Spread - As of December 5, compared with November 28, all maturities of US Treasury yields except the 1-year yield increased. The 10Y - 2Y US Treasury term spread widened 3bp to 58bp [9]. 4. Sino-US Yield Spread - As of December 5, compared with November 28, the inversion of the Sino-US 10-year Treasury yield spread widened 11bp to 229bp. In the short term, the 10-year US Treasury yield will continue to rise slightly, while the 10-year Chinese Treasury yield is expected to fluctuate within a narrow range, so the deep inversion will continue [12].
