IG9 10Y spreads re-surged today and were very choppy into the close as they broke back above 155bps (at 155.5/157.5bps now) for the first time since Mid-December with a 31% rip in the last two weeks. This fits perfectly with our ongoing thesis of this being a tail-risk hedge (not a simple 'spread' as other ignorant commentators presume) whose risk management has exploded in their face. While the skew (the difference between the index and its portfolio fair-value) has collapsed and arbs will be happy and likely exiting - the same correlation shifts (that we discussed earlier [5]) that drove the big bank to sell more and more protection into a spread compressing market are now back-firing as systemic risk re-surges and the correlation shift is forcing them to buy back more and more protection into a spread decompressing market. Oh the fun of negative convexity - especially when you ARE the market and there is no-one to unwind the actual tranches to.
While we among others expected the selling to slow as the skew collapsed, the secondary effect of the actual rise in systemic risk is now taking over and forces the bank to buy protection back into a rising spread market...

but the velocity of the change is incredible...
