Not sure why the 10y yield should go down if the Fed starts hiking (setting aside any near-term volatility)
FED
It's popular to suggest the 10y yield will fall if the Fed hikes rates this week.
Unless this is a "one and done" hike, though, history suggests the 10y will rise as the hike cycle progresses.
The 10y has risen in every modern hike cycle (especially early in the cycle).
