Big $ has ways to make markets pump in order to offload before the unwind begins.

Remember BLK is one of the biggest dealers in UST's, they're trying to sell T bills for cash so they can use their discount to buy the call options off of ppl they sell the T bills to.

BLK has a vested interest in yelling that rates should go higher until the fed has to capitulate on rate caused problems. At which time they're holding all those calls... BLK was shorting T bills through puts, don't think they won't also buy calls on them as well.
