NEW YORK, April 26 (Reuters) - The euro fell and Greek debt came under intense pressure on Monday on renewed jitters over Greece's bailout, while U.S. stocks mainly edged lower on fears that the financial reform making its way through Congress will curb bank profits.
U.S. government debt prices were little changed with investors unwilling to commit to a strong market position ahead of the Federal Reserve's two-day policy meeting that begins on Tuesday. [
]The euro fell against the U.S. dollar for the seventh of eight trading sessions and fell to a three-month low against sterling as investors fretted about the potential conditions attached to loans from the European Union and International Monetary Fund to Greece. Germany said aid could come in days if Greece agreed to painful new austerity measures.[
] [ ]Greece said on Sunday that 45 billion euros ($60.5 billion) in planned EU-IMF assistance would arrive in time to refinance an 8.5 billion euro bond on May 19.
"Aid for Greece still doesn't seem like a completed deal, so all the uncertainty about the timing and details of a Greek plan limits demand for euro," said Michael Malpede, analyst at Easy Forex in Chicago.
Greek borrowing costs hit a 12-year peak as fears mounted that the aid would come too late to avert the euro zone's first sovereign debt default.
"Until the cash is on the table investors will continue to demand very high risk premiums on Greek bonds," said Nick Stamenkovic, strategist at RIA Capital Markets in Edinburgh.
The euro fell 0.2 percent to $1.3362 after earlier hitting a session low of $1.3291 <EUR=>.
The weaker euro pressured gold prices, but news of limited gold sales by the International Monetary fund provided underlying support. Traders said the news on the IMF's gold sales, reported by the World Gold Council, confirmed a market view that renewed interest among central banks in the wake of currency volatility would help limit official-sector gold sales.
Spot gold <XAU=> hit a peak of $1,159.73 an ounce before sliding $4.55 to $1,152.30. U.S. gold futures for June delivery <GCM0> settled up 30 cents at $1,154 an ounce in New York.

"Most of the big banks' profits come from trading and if you restrict their trading profits, that's going to restrict their overall profits," said Keith Springer, president of Capital Financial Advisory Services in Sacramento.
Springer said that regional banks also will be hurt even more "because they can't make up the cost of the fees the financial reform is going to charge them."
Top European shares rose, with the FTSEurofirst 300 <
> index closing up 1 percent at 1,103.00 points.Optimism about economic growth and commodity demand helped European miners, which also benefited from a rise in key base metals prices.

U.S. Treasury debt prices began the day higher, spurred by safe-haven bids on Greek debt concerns, but caution ahead of the Fed's policy meeting on Tuesday and Wednesday muted gains.

The yield spread against German Bunds scaled 12-year highs as the cost of insuring against a default by Greece hit a record high. Sovereign credit risk fears also boosted the cost of insuring Portuguese debt to new highs.
The Greek/German 10-year bond yield spread <GR10YT=TWEB> <DE10YT=TWEB> climbed to 680 basis points, passing the previous record set last week of 611 basis points, and matching levels last seen in February 1998.
