* U.S. stocks fall, trading volume lowest for the year
* Euro gains on expectations ECB will raise interest rates

NEW YORK, March 28 (Reuters) - The euro rose on Monday on expectations of higher euro-zone interest rates while U.S. stocks slipped late in the day as concerns about the Middle East and Japan outweighed positive economic data.
The euro rose above $1.41 after European Central Bank President Jean-Claude Trichet said inflation is above the bank's price stability target, adding to expectations interest rates could be raised as early as next month.
The single currency erased most of its gains later, however, pressured by worries that the defeat of German Chancellor Angela Merkel's party in a key state election means she will have less leeway to offer financial support for debt-stricken members of the euro zone.
Data showing U.S. consumer spending rose for an eighth straight month initially supported equities, allowing European markets to finish near flat. But U.S. stocks erased early gains and closed lower as lingering worries about unrest in the Middle East and Japan's nuclear disaster left investors cautious.
Trading volume was the lowest so far this year on the New York Stock Exchange and the Nasdaq. In Europe, volume in the FTSEurofirst 300 index reached only 60 percent of its 90-day average.
"It puts a cap on things for right now, at least until we start to see some earnings come out early in April. That might finally give us a little more upside, assuming that we have good earnings," said Janna Sampson, co-chief investment officer at OakBrook Investments LLC in Lisle, Illinois.
"At some point people have got to price in Japan's problems and the problems in the Middle East that we know about."
Fears of disappointing U.S. corporate earnings also increased late in the day after hotel operator Marriott International warned that higher gasoline prices may dampen demand for leisure travel. For details, see [

]Yields on two-year U.S. Treasuries notes rose after an auction of two-year notes, the first in three weeks, indicated higher yields may be needed to attract bidders on this week's five-year and seven-year note sales.
A $35 billion sale of two-year notes <US2YT=RR> priced one basis point wider than where the notes had traded ahead of the sale, though bidding by indirect bidders was relatively strong at around 33 percent.
