* U.S. Treasuries gain on safe-haven bid
* Dollar rises vs euro as risk-aversion remains (Updates to close of European markets, updates U.S. markets)

NEW YORK, May 18 (Reuters) - The euro fell on Tuesday despite progress on a rescue package for debt-stricken Greece and U.S. stocks fell in choppy trade as the weakness of the euro stirred concerns about the impact on sales of technology companies with big overseas sales.
Investors' aversion to risk remained high, despite progress on a rescue package for Greece, driving up U.S. Treasury prices. Some analysts questioned the sustainability of the global economic recovery and the ability of the U.S. Federal Reserve to begin to move away from keeping short-term interest rates near zero percent.
European shares, however, rose, snapping two consecutive days of declines, after Greece received funds from the European Union to repay its immediate debt. Banks rebounded and were among the best performers after a flat performance on Monday.
But another wave of caution colored investor sentiment after the close of European markets, and U.S. safe-haven assets strengthened as investors worried about the long-term sustainability of the 750 billion euro ($925 billion) plan to rescue the debt-laden euro zone.
"It's a one-two punch: First is continuing concern over the euro and continuing concern over the viability of the (single currency) union, and then second is rotation out of large-cap tech," said Peter Kenny, managing director at Knight Equity Markets in Jersey City, New Jersey.

In economic news, ZEW economist Michael Schroeder said the euro zone rescue package would weigh on medium-term growth in Germany as budget cuts reduced demand.
Earlier, the ZEW Institute reported that its May German economic sentiment index fell more than expected in May. [
]U.S. Treasuries rose as the euro weakened against the dollar and Wall Street stocks fell from earlier gains. The 30-year bond rose a full point as investors viewed it as cheap relative to other Treasuries.
"There is some fine-tuning of risk positioning," said Michael Woolfolk, senior currency strategist at BNY Mellon in New York.
The 30-year bond <US30YT=RR> rose 1-5/32, its yield easing to 4.29 percent from 4.36 percent on Monday.
The benchmark 10-year U.S. Treasury note <US10YT=RR> was up 14/32, with the yield at 3.4385 percent. The 2-year U.S. Treasury note <US2YT=RR> was up 1/32, with the yield at 0.7854 percent.
The euro <EUR=> fell 0.31 percent at $1.2355 per dollar, while against the Japanese yen, the dollar <JPY=> was down 0.11 percent at 92.48.
Earlier, the euro had risen against the dollar on optimism that financial aid for Greece was coming through as planned.
"We believe the 'breather rally' in EUR merely represents a selling opportunity, as the currency will be plagued by austerity in some countries and loan guarantees out of the other countries -- hardly a recipe for a buoyant regional economy and/or stronger currency," said T.J. Marta, chief market strategist at Marta on the Markets LLC, long before the euro fell on the day.
Officials said Greece received a 14.5 billion euro emergency loan from the European Union and would use some of the money to repay in full an 8.5 billion euro bond maturing on Wednesday [
].That helped narrow the 10-year Greek/German government bond yield spread and cut the cost of insuring against a Greek default, supporting the euro.
U.S. crude oil futures rose sharply <CLc1>, rising 1.7 percent to $71.31.
