I don't think so -- Citi is unlikely to have a major liquidity problem since they've attracted major investments from overseas and have billions of dollars in assets from their retail and commercial banks.

Lehman might be next... their stock was off 13% or so on Friday, and their credit default swaps are trading around 500 basis points... people aren't very upbeat.

Citi's problem isn't liquidity, it's solvency. One look at what terms they took that major investment from overseas is enough to tell that you should be very far from anything that loses value when citi blows up.
