It looks like some funds were buying some cheap insurance. The CBOE S&P put/call wasn't that out of the ordinary, so it looks like the BSC thing scared some folks today.
However, I can't recall seeing so many out of the money puts bought so close to expiration in probably more than 6-years.
They couldn't get to 1350 for expiration, so they may take it below 1250 post Fed.
Bonds seem to be pricing in a 1% or more Fed Funds cut even if the Fed Funds Futures are only pricing in 0.75%.
