Typically I have seen that when everyone is on one side of the trade its quite easy for the market to make fools of the participants. The speculative short position on US treasuries, specifically the 10 year, is massive (and for good reason).
While I remain a longer bear view on these treasuries I think we might end up seeing a short squeeze before we see 3% yields.
The 10 year is showing some signs this could accelerate and hurt alot of bears who need to cover their positions.
