彭博9月8—10日調查122名市場參與者，77.8%認爲10年期美債收益率升至5.00%—5.75%會觸發標普500年內回調10%；但選擇最多的是5.00%—5.25%，佔29.5%，中位受訪者的閾值實際落在5.25%—5.50%。因此，5%更像風險區間的入口，並非華爾街公認的機械“崩盤線”。

Brent rose 3% to $104.74/bbl and WTI climbed 2.8% to $99.33/bbl after an attack prompted a precautionary shutdown of Saudi Arabia's east–west oil pipeline and a Gulf regional meeting was postponed.

U.S. Treasury yields were mostly lower as investors awaited a likely Federal Reserve rate increase on Wednesday; only the ultra-long Treasury ticked higher. TD Securities says it expects the FOMC to raise policy rates 25bps in September, marking the start of a tightening cycle, and forecasts cumulative hikes of 75bps through Q1 2027, with further increases penciled in for October and January. 2‑year Treasury yield down 3.3bps at 4.610%; 10‑year down 1bp at 4.964%; 30‑year up 0.8bp at 5.362%.
