The June 2015 long bond contract has jumped nearly 10 full points. Reuters reports that a bid for 500 lots hit at 2:08 pm were the culprit.
Looks like some kind of fat finger. Gotta fade that.

Liquidity is very light outside of the front month but it’s showing bid at 151-05 still.

Update: Now there’s talk that yesterday’s settlement price was wrong and the cheapest-to-deliver basket was wrong. I still struggle to understand why there should be an 11-point difference in the March/June prices.
Update 2: The CME changed the delivery basket. What seems to be the problem, and what could explain the huge difference in price between the March/June contracts is that they’ve changed the cheapest-to-deliver basket.

So if it’s not a fat finger, I’d like to know what that 500-lot was priced at.
