Let me see if I got this right after reading the article:
1. Banks still try to make money by attempting to outguess market changes and move money at opportune times. That's the whole point of financial markets.
2. This practice carries a risk that if you guess wrong on the timing, you can end up with less money then you started with.
3. JPMorgan guessed wrong in some complicated market movements and lost $2 Billion dollars.
4. The $2B in question was the bank's money, not government funds and not depositor's funds.
So freaking what? Sorry for the shareholders, and whoever inside JPMorgan this'll get pinned on, but how is this a regulatory issue? They took a risk, and flubbed it. BFD. It was their money to risk and lose.*
*Caveat: If they ask for tax payer funds to stay afloat, *expletive deleted*ck 'em. That's what risk is about. I said that with Goldman Sachs and Chevy too though.
