Draghi sounded more like Federal Reserve Chairman Ben S. Bernanke than Trichet, said Trevor Greetham, Director of Asset Allocation at Fidelity Worldwide Investment in London. “He put much more emphasis on growth. This suggests another rate cut in a month's time.”

The euro fell after the ECB rate cut before recovering to trade little changed at $1.3828 at noon in Frankfurt today. Italian bond yields, which declined from euro-era records yesterday, rose today. The 10-year yield gained 5 basis points to 6.22 percent.

Draghi was under pressure to step up the ECB's bond purchases to stop the two-year-old debt crisis spreading to Italy, the region's third-largest economy.

Irish Finance Minister Michael Noonan called on the ECB to use a “wall of money” to halt speculation and contagion after Greece's decision to hold a referendum on its second bailout fueled concerns it may default on its debts.

Germany and France raised the stakes, saying they would interpret it as a vote on Greece's euro membership, prompting Greek Prime Minister George Papandreou to backtrack on the plan.

“Despite the Greek shenanigans about a referendum, the market situation is not worrying enough for the ECB to pull out the ultimate stops,” said Christian Schulz, senior economist at Joh. Berenberg Gossler & Co. in London. “The ECB is still far away from forcefully intervening to protect illiquid but solvent sovereigns.”

Draghi's 23-member Governing Council is already split over the ECB's bond purchases, which now amount to 173.5 billion euros ($239.4 billion).

The ECB says the purchases are aimed at ensuring its interest rates are transmitted in financial markets. German policy makers say they also reduce borrowing costs for profligate governments, blurring the line between monetary and fiscal policy.

Bundesbank President Jens Weidmann opposes the program and ECB Executive Board member Juergen Stark will step down at the end of the year over the issue.

Stark reiterated at an event in Frankfurt today that he is “no fan” of the bond purchases as they “set the wrong incentives.” He defended the rate cut, saying the economy may not grow at all in the fourth quarter, damping price pressures.

ECB council member Yves Mersch told Luxembourg's Tageblatt newspaper late yesterday that the economy is “practically in freefall.”

German factory orders unexpectedly plunged 4.3 percent in September, the country's Economy Ministry said today. A separate report showed Europe's services and manufacturing output contracted at the fastest pace in three years in October.

“I struggle to see how in the current environment, with inflation starting to decline in the coming months and with activity clearly weakening, asset purchases would be such a bad thing,” said Jens Larsen, London-based chief European economist at RBC Capital Markets and a former Bank of England official. “But bond purchases on a large scale seem to have basically been ruled out of the toolbox, at least for now.”

Jennifer McKeown, an economist at Capital Economics Ltd. in London, said lingering concerns about price stability may be one reason why the ECB doesn't engage in full-blown quantitative easing like the Fed and the Bank of England.

Keeping inflation just below 2 percent is the ECB's primary mandate. It is currently running at 3 percent.

“A big move into QE may mean inflation rises in future,” said McKeown. The ECB is also “very reluctant to step in to what it considers to be the role of the region's governments,” she said. “It's a role for fiscal policy, not monetary policy.”

Draghi, 64, ruled out the ECB becoming “the lender of last resort for governments” and said the responsibility for financial stability rests squarely with politicians.

“Draghi made it clear that sovereign governments must not count on external help,” said Axel Merk, chief investment officer at Merk Investments LLC in Paolo Alto, California. “It's really very simple: get your act together, national governments, and you'll be fine. If not, you'll pay the price.”

While Group of 20 leaders meeting in Cannes, France, today heaped pressure on Europe to solve its debt crisis, they failed to agree on increasing the resources of the International Monetary Fund so that it could provide more foreign aid.

Governments are awaiting further details of Europe's week- old rescue package before they commit cash, German Chancellor Angela Merkel said.

The Organization for Economic Cooperation and Development on Oct. 31 forecast euro-area growth will slow to just 0.3 percent next year while U.S. expansion accelerates to 1.8 percent.

Of 55 economists in a Bloomberg News survey, 49 predicted Draghi would keep rates on hold at his first policy meeting to emphasize his inflation-fighting credentials. He proved them wrong.

“Central bankers tend to do what needs to be done,” said Jacques Cailloux, chief European economist at Royal Bank of Scotland Group Plc in London. “Draghi might be reluctant to step up the bond purchases now but if the situation deteriorates further, he will have to.”
