Arbitrage: Why are MtGox and BTC-E USD/BTC prices so far apart?

[ihsotas]

Here's the current state of affairs, as of 4:09 PDT. MtGox is at 116, and has been over 114 for hours. BTC-e is at 108 and has been below 109 for some time as well. Why is no one holding USD and BTC in both places and arbing the heck out of these two markets?

People want to get their money out of MtGox and BTCs are easier to get out, so the price is higher there.
It's just the risk of the law suit/seizure against Mtgox.
If you don't mind that, yes you could make quite some money.

The MtGox / Bitstamp market, currently a 4.7% premium to hold dollars at MtGox.

Certainly something to watch over the next few days.

Price is high on Mt Gox because people are starting to worry about their dollars being frozen or seized on Mt Gox, so they buy bitcoins and withdraw those bitcoins to another exchange or to their own wallets.
