NEW YORK, Jan 21 (Reuters) - Share prices dropped sharply on Thursday after U.S. President Barack Obama proposed new limits on top bank risk profiles, spurring safe-haven U.S. Treasury purchases but undercutting gains for the U.S. dollar.
Obama said he is ready to fight the financial sector and its lobbyists for rules that would bar banks from owning, sponsoring or investing in hedge funds or private equity funds for their own profit, causing a bank share sell-off. For more see [

]"If you look at bank earnings over the last few years, what some of the more astute banks have been able to do is to smooth (out) their earnings using trading activity," said Subodh Kumar, chief investment strategist at Subodh Kumar & Associates in Toronto.
"Presumably this (proposal) is going to hold that down. So the ability to generate revenues just by trading on their own accounts is going to go down."

The potential for a redrawing of how Wall Street banks operate had a ripple effect across asset classes.
The proposals caused a sell-off in the U.S. dollar. It fell sharply against the yen and relinquished gains against the euro, which earlier hit a six-month low against the U.S. currency.
"The dollar is taking it on the chin after these comments, as the implication is they are negative for bank profitability. Everyone was looking for the dollar to continue rallying but the mood has definitely soured," said Shaun Osborne, senior strategist at TD Securities in Toronto. [
