Video, five minutes. I think we don’t have anything to worry about. The repo thing sounds like a lot of hype to me. The “spike” they talk about was probably a freak thing that doesn’t matter. If anything TPTB need to worry about, it would Joe Sixpack neglecting to make payments on house and car loans.
