Quote from cdcaveman:
your short one outright, and long the other outright.. with no margin relief..
You get margin relief. It's traded as one product, there is no legging. It has it's own ticker. I think the margins are $700 or so. I guess I should point out that the "most" liquid and often quoted duration is the 3 month treasury bill over the 3 month ED. I don't want Martin to come in here and bust my chops on a technicality. LOL.
BTW, here is a nice illustration of the TED spread in 2008. Notice how this bad boy broke out big time early in 2007 while stocks continued to make new highs for months on end. This was the early warning sign that credit was freezing.
