Any thoughts???

Quote from nysetrader78:
Interesting points SethArb.......ones that I have already pondered given that I am a prop trader and not only have seen my P&L swing drastically (thankfully to the upside for the most part also) but even more so with other large BP traders around me.
However, the original concern was more along the lines of whether the Prop firms would be able to continue to secure the BP they need via access to loans and leverage without and issues related to excess cost and availability.
Maybe Don can clarify this, but my understanding of Prop leverage is that the firm pools the traders capital and their own invested capital, and then borrow the remaining money needed on a daily basis to meet their capital requirements. I believe the max legal leverage for the firm itself is somewhere around 6 or 7 to 1.....correct me if Im wrong Don. This total aggregate BP for the firm is then allocated to the traders as they see fit obviously.
So my question is, will it become considerably more expensive for the Prop firms to borrow the remaining capital needed, drastically changing their level of profitability? Also is it possible that they will not be able to borrow this money at any cost due to lack of liquidity? Maybe I am stretching here, but it seems like a relevant point given our current state of affairs.
