NEW YORK, March 27 (Reuters) - Stock prices fell around the globe on Friday as investors decided to take the money and run after a stunning 20-percent rally from lows earlier this month, while political strains punished the euro.
The dollar scored its best day in more than two months against the euro, bolstered by a growing view that the European Central Bank may be the next to purchase its own bonds to stimulate growth.
A stronger dollar hurt oil and gold. As has often been the case since the start of the economic crisis, the rising dollar also coincided with weakening stocks.
Wall Street capped a strong week on a down note as investors booked profits in the wake of the recent surge, and bank shares dropped after bank executives indicated March had been a tougher month than the previous two.
After a meeting with President Barack Obama, the chief executives of JPMorgan Chase & Co's <JPM.N> and Bank of America Corp's <BAC.N> poured cold water on investor hopes for a rebound in the first quarter.
"Given that's kind of where this rally started in the second week of the month with Citigroup and Bank of America indicating they had a good first two months, it would make sense that his comments would have a negative impact," said Peter Jankovskis, director of research at OakBrook Investments LLC in Lisle, Illinois, referring to JPMorgan chief executive Jamie Dimon.

CRUDE PRESSURED

The dollar's strength against the euro and easing stock markets helped pressure crude, along with a consultancy report of OPEC producing over the group's output target in March.
In the fixed income markets, prices for 30-year U.S. Treasury debt rose as traders made more bullish bets in hopes of profiting from the Federal Reserve's planned purchases of long-dated government securities.
But other maturities ended flat to lower, as traders booked earlier gains tied to the Fed's $7.5 billion purchase of debt maturing in the next two to three years.
The Fed has embarked on a program to buy up to $300 billion over the next six months in an effort to ease credit conditions throughout the world's largest economy.
On Friday, the Fed bought $7.5 billion in Treasuries maturing in the next two to three years, matching the amount of intermediate issues in its debut purchases on Wednesday.
The 30-year long bond <US30YT=RR> rose 28/32, with the yield at 3.608 percent.
"The mantra of 'Buy what the government buys' has infiltrated the market," said Richard Schlanger, portfolio manager with Pioneer Investments USA in Boston. "People are trying to get ahead of the Fed."
