LONDON, Dec 3 (Reuters) - A darkening outlook for the euro zone economy clipped global stocks on Wednesday and helped send the 30-year euro zone government bond yield to an historic low as investors looked for aggressive interest rate cuts in Europe this week.
Wall Street was set to track European bourses lower with U.S. stock index futures all in the red.
The euro stayed on the back foot a day before the European Central Bank, Bank of England and Sweden's Riksbank are all widely expected to cut borrowing costs.
Supporting those expectations, economic reports on Wednesday showed the euro zone's services economy fell deeper into recession in November than initially thought and inflationary pressures eased. (For details please double click on)
"This is a horrible survey across the board, showing that the euro zone service sector is being hit ever harder by the financial crisis, muted consumer spending and markedly weaker activity in key export markets," said Howard Archer, economist at IHS Global Insight.
A separate report revealed that retail sales in the region dropped by a worse-than-expected 0.8 percent in October from the previous month.
The FTSEurofirst 300 index of top European shares fell 0.6 percent with Britain's FTSE 100 index down 0.1 percent and Germany's DAX shedding 1.0 percent.
MSCI world equity index eased 0.2 percent.
Earlier, Japan's Nikkei managed to eke out a 1.8 percent gain following a rebound on Wall Street on Tuesday, and MSCI's index of other Asian stock markets put on just 0.4 percent.
The news flow in Asia was negative too with Australia's economy growing at its slowest pace in eight years in the third quarter.
Thailand slashed rates by 100 basis points and South Korea took steps to help local banks through a cash crunch. See
Central banks worldwide are cutting rates to fight recession. They are also considering more measures to stabilise financial markets and restore battered consumer and investor confidence, including help for struggling U.S. auto makers.
The ECB meets on Thursday and most economists expect an interest rate cut of 50 basis points, while the Bank of England is forecast to cut rates by an aggressive 100 basis points.
Sweden's central bank is likely to slash rates by a record 100 basis points, or possibly more, on Thursday when it announces the result of its meeting, which it brought forward by almost two weeks.
EURO PRESSURED AS ECB CUT EYED
Also under pressure, the euro fell 0.5 percent against the dollar on the day to $1.2643 and was also weaker against the yen , while the dollar climbed 0.5 percent against a basket of major currencies. The yen was also broadly firmer.
"The slew of dour fundamental data has raised expectations that the ECB will cut rates by more than the consensus forecast of 50 basis points, which could lead to the euro breaking from its current range," said John Rivera, currency analyst at Forex Capital Markets in a research note.
"The single currency has traded between $1.2400 and $1.3000 since late October and it may take an aggressive move from the central bank to sink it below support."
U.S. and euro zone bond yields were mostly higher on the day, reversing an early move lower, but yields have been trending down as demand for less risk assets mounted.
The 30-year euro zone government bond yield plumbed 3.319 percent earlier, a record low according to Calyon, before returning to 3.407 percent, while the 10-year euro zone bond yield hit a 3-year low of 3.004 percent, before edging up to 3.101 percent.
The benchmark 10-year U.S. Treasury note yield rose 4 basis points on the day to 2.746 percent, but held near a five-decade low of around 2.65 percent set on Monday.
Oil steadied near $47 a barrel after touching a 3-1/2 year low of $46.82 on Tuesday but stayed on shaky grounds given the risk that weekly data due out later in the session could show further signs of weakening U.S. oil demand.
Gold slipped towards $774 an ounce, down from $781.50 late in New York on Tuesday as a firmer dollar against the euro dented the metal's appeal as a currency hedge. (Additional reporting by Rafael Nam in HONG KONG; Editing by Victoria Main)
