NEW YORK, March 31 (Reuters) - U.S. stocks gained on Monday as a regulatory overhaul in Washington propped up financial shares, but shares in Europe closed lower as renewed concern about the credit crunch hit bank stocks.
But the close of the first quarter saw a dismal performance for stocks in both the United States and Europe. Among U.S. indexes, the bluechip Dow fell 7.55 percent in the quarter, while stocks in Europe had their worst quarterly performance in over five years.
The persistent concerns about the global banking system also drove up prices of U.S. government bonds, capping their best quarter in five and a half years.
And in foreign exchange markets, the euro came close to a record high against the dollar as higher-than-forecast euro-zone price data reinforced expectations that the European Central Bank will not start cutting interest rates soon.
The dollar was headed for its biggest quarterly loss against the euro in four years.
In U.S. stocks, the three major indexes closed higher as investors exhibited cautious optimism regarding a White House plan to boost the Federal Reserve's role in overseeing financial institutions.
But there was broader skepticism that this and other measures to unclog the banking system, such as massive liquidity injections from global central banks, would do the trick.
"The Fed measures are lending some stabilization to the market, but it doesn't seem like the financing aspect for banks is getting any better," said Sean Murphy, bond trader with RBC Capital Markets in New York.

The Nasdaq Composite Index < > was up 17.92 points, or 0.79 percent, at 2,279.10.Equities found some comfort in data from Chicago purchasing managers showing that the Midwest factory sector, while still contracting, was do so at less severe pace.
In Europe, the pan-European FTSEurofirst 300 index closed down 0.26 percent at 1,262.14 points. The index is now down for five straight months, its worst run since a six-month stretch of declines from April to September 2002.
Banks were the worst performing sector in Europe after a Merrill Lynch research note said Switzerland's UBS<UBSN.VX>, one of the biggest casualties of the credit crunch among Europe's large banks, may see further write-downs.
"You can break the market down into two components. You've got the credit crunch affecting financials and then you've got the economic slowdown," said Kevin Lilley, a portfolio manager at Royal London Asset Management who helps manage 1.1 billion euros ($1.74 billion).
"We are now five years into this economic cycle and I think people's estimates are way, way too high," he said, adding: "It is difficult to see the market making major headway when there are going to be major downgrades coming through."
UBS shares fell as much as 4.8 percent after Merrill Lynch said it expected the bank to make a further $11 billion of first-quarter write-downs, resulting in a loss of 8.2 billion Swiss francs ($8.22 billion) in the first three months.
UBS ended down just 0.4 percent on Monday but has fallen nearly 50 percent this quarter, bearing the brunt of investor panic over write-downs.
The barrage of bad news from the banking sector was unrelenting. Over the weekend, Lehman Brothers <LEH.N> became embroiled in what it says was a fraudulent scam in Japan that the firm claims cost it $352 million.
The dispute arose as Lehman has been beset by market rumors that it could see a run on the bank similar to the one that dragged down rival Bear Stearns <BSC.N>. Lehman has said it has more than enough capital to do business in the current environment.
Persistent worries about the global financial system, bolstered Treasury debt prices, with benchmark 10-year notes <US10YT=RR> up 7/32 and offering a yield of 3.41 percent, down three basis points.
The need for funding by cash-strapped banks and other financial institutions put upward pressure on short-term borrowing costs as the first quarter drew to a close.
"From a credit market perspective, we still have a rocky road ahead, but much of the mess is behind us," Andrew Harding, director of taxable bonds at Allegiant Asset Management in Cleveland.
A reversal in the record-prone commodities sector continued, meanwhile, with oil prices plunging $5 to below $101 a barrel on expectations Iraqi oil flows disrupted by a bomb attack last week would be fully restored over the next day.
The drop in energy prices dented gold's appeal as a hedge against oil-led inflation.
In metals, June gold <GCM8> closed down $15 or 1.6 percent at $921.50 an ounce.
The losses in gold and crude oil came as the dollar reversed earlier losses against the euro, which had earlier flirted with record highs on expectations that the ECB would not start cutting interest rates soon.
A report showing annual euro zone consumer prices rose in March at their fastest pace since the euro was launched in 1999 earlier sent it as high as $1.5895, just shy of a record high set two weeks ago, before investors booked profits and pushed it back to $1.5776 <EUR=> in late New York trade.
"The euro's upward trend lost some momentum today but that doesn't change the underlying bearish dollar sentiment," said Matthew Strauss, currency strategist at RBC Capital Markets in Toronto.
"To call a bottom now is still a very risky call. It's too early to say the worst is behind us and the dollar's in for a sharp rebound." (Additional reporting by Steven C. Johnson and Richard Leong; Writing by Lucia Mutikani; Editing by Leslie Adler)
