Back at the start of August, when 10Y TSYs were trading just around 4.00%, Bill Ackman sparked a modest selloff in rates when, without telling the world something it didn't already know, he tweeted he was shorting 30Y due to "higher levels of long-term inflation including de-globalization, higher defense costs, the energy transition, growing entitlements, and the greater bargaining power of workers" the bond market could "reprice the long end of the curve in a matter of weeks, and this seems like one of those times."

The market reaction was instantaneous, with 10Y yields - after earlier breaching 5.00% for the first time since 2007 - certifying that they now trade as pennystocks, and tumbling more than 7bps on Ackman's tweet alone, down to 4.91%.
