近期10年期国债收益率备受关注，但短期政府债券收益率也出现了大幅波动。
The yield on the 10-year note has gotten a lot of ink lately, but the yields on shorter-term government bonds have also been swinging.
其重要性在于：短期美国政府债务深受市场对美联储未来货币政策预期的影响。
Why it matters: Shorter-term U.S. government debt is heavily influenced by market expectations for what the Federal Reserve will do next on monetary policy.
最新情况显示，两年期国债等短期债券收益率波动剧烈，反映出经济背景的不确定性。
The latest: And those yields — for instance on the two-year note, shown above — have been volatile, reflecting an uncertain economic backdrop.
此外，随着经济前景变得模糊，市场仍在试图揣摩美联储的后续行动。
On top of that, the market is still trying to figure out how the Fed will behave as the economic outlook turns foggy.
道明证券美国利率策略主管Gennadiy Goldberg表示，美联储清楚必须收紧政策，但尚不确定收紧的速度和幅度。
What they're saying: "The Fed knows they're going to have to tighten policy. They just don't know how quickly and how far," Gennadiy Goldberg, head of U.S. rates strategy at TD Securities, tells Axios.
他认为美联储可能需要采取更多行动，但同时也试图淡化其意图通过紧缩政策扼杀经济的说法。
"They'll probably need to do more," Goldberg says. "But at the same time, I think they're pouring some cold water on the narrative that they're looking to kill the economy in the process.
总之，美联储的不确定性在市场中得到了映射，这也是债券市场波动剧烈的部分原因。
They're not." Bottom line: That uncertainty at the Fed is being mirrored by the markets, which is part of the reason why bonds have been so volatile.
