"On the one hand, ECB executive board members have tried to dampen rate cut speculation over recent weeks, and on the other, important sentiment indicators have increased once again."

On Friday, the purchasing managers' index for the entire euro area hit a nine-month high, offering hope the single-currency area could be moving out of its deep double-dip recession.

Recent data for Germany, Europe's biggest economy, has also come in better than expected. And German Finance Minister Wolfgang Schaeuble even went so far as to say he believed the embattled euro zone was now past the peak of its three-year-long debt crisis.

Market tensions have indeed eased since the ECB unveiled its anti-crisis bazooka in September, the so-called OMT bond-purchase programme.

The scheme is credited with marking a turning point in financial market sentiment towards the crisis-wracked euro even though it has not actually been used.

With markets now calmer, the ECB has been able to keep its gunpowder dry, keeping interest rates at their all-time low of 0.75 per cent and holding fire on other emergency anti-crisis measures, after pumping vast amounts of liquidity into the markets at the beginning of last year.

Nevertheless, at last month's meeting, Draghi appeared to open the door to further reductions in interest rates, crucially revealing that there had been "wide discussion" of such a move on the decision-making governing council and that the decision to keep rates on hold was anything but unanimous.

Commerzbank's Schubert pointed out, however, that top board members - such as Yves Mersch, Peter Praet and Joerg Asmussen - had all sought to play down possible rate cuts recently.

Deka Bank chief economist Ulrich Kater was similarly convinced that Draghi would not announce any monetary easing at his first press conference of the year.

"The policy of low interest rates is finally making itself felt in the periphery countries, thereby taking the pressure off the monetary-policy actors to come up with new stimulus measures," he said. "For the time being, there is no immediate need to act."

In the United States, the Federal Reserve hinted last week that its own huge programme of stimulus measures was under review and could be brought to an end this year.

Capital Economics economist Jonathan Loynes cautioned, however, that "having prevented catastrophe in 2012 by pledging to do whatever it takes to save the euro, the ECB will have to follow words with actions in 2013".

While Loynes said he was expecting no policy changes to be announced on Thursday, "the pressure for action may soon be irresistible".

Postbank economist Thilo Heidrich said the likelihood of a rate cut was "wide open", but that he was betting on a further quarter-point reduction in the key refinancing rate to 0.5 per cent in the early months of this year and the ECB would keep it there "for some time to come".

Loynes said that "despite the sizable challenges facing the ECB [in 2013], it appears unlikely that it will take any steps towards meeting them at its meeting in January".

"No doubt Draghi will reaffirm that the ECB is ready to implement OMTs … and he may even show signs of warming to the idea of a cut in interest rates," Loynes said.

"Either way, though, he is likely to keep the onus on governments by stressing once again that the ECB cannot solve the region's debt crisis single-handedly."
