We were under pressure again today but managed to push higher so far tonight. Mortgages continue the monster rollover from their Dec 109 and 110 calls into the March 110 and 111 calls, all told about 50,000 at each strike this week. PIMCO is now selling the March 106-111 strangle in the 10yr options for 43 ticks, this could end up being about 150,000 short over the next few months. We have had our volatility bid as we traded to the upside with the convexity buying (but now vol is drifting back toward 4% in the 10yr). Now we are almost back to the 4.65% 10yr cash yield level where it all started. PCE tomorrow should be telling of whether this curve can flatten anymore past -10 basis points.
