The mortgage guys continue to buy calls as we dip. As of late though Countrywide is pretty much set in their position. They are long about 50,000 May 110 calls and both April 109 and 110 calls at least 20,000 a piece. They setup this position in mid-to-late January and haven't done much size since. On the other hand, Wells Fargo waited on their convexity hedging and bought calls as we began to breakdown from above the 109 handle. He is currently long about 30-40,000 June 110 calls and another 30-40,000 of the May 110 calls. Countrywide has yet to roll any of his position into the June (would imagine will do 109's and maybe even some 108's) and neither of them are active on the put side at all. As for implied vol, we have had an uptick as of late but still at historically low levels, would imagine if we can break to 106 in the next few weeks it may catch a solid bid. The biggest players in 30yr options continue to buy the April 111-115 strangle versus selling the June 109-117 strangle (about an 8,000 lot position that he scalps over a month or so period every expiration cycle for the last few months). He sold this initially with the June at 3 ticks over and is taking a little beating with the June now 10 ticks over, so back month vol was a little more bid than he anticipated. Yes, I think the inverted curve is correlated with higher implied vols because this was very unexpected (especially in 10's/30's) by some of the bigger hedge funds who put on steepning bets on the 10-30yr swaps and cash spreads.
