The rise in Treasury yields should accelerate in Oct and Nov.

There is no resistance at all up until here. Consider the 10y paper is already at 2% or slightly below. And it may happen before the election. The question is, what will happen after that: technically we can go further and further in wave C, easily smashing 3.2%. If this happens, then we have a true trend change, and the 40-year long bullish cycle in Treasuries will be over.
