Wouldn't it have to? You can't take out a loan for a VC venture for less than 5% considering the extreme risk involved in a poorly run fund. I'd imagine debt financing would be cost prohibitive even if you found a bank crazy enough to loan you the money.
Are you sure that banks don't somehow have a hand in these funds. I don't know -- just guessing that easy money has something to do with all of the cash getting tossed around right now.
