The European Central Bank needs to stick to its already laid out policy path, several policymakers have argued today. 

Economic growth is gaining momentum and the euro zone may be on its best economic run in a decade. 

But inflation is still not moving decisively higher, the policymakers argued, hinting at little appetite for now to amend the ECB's policy stance. 

The comments gel with Reuters report this week that policymakers are wary of making any new change to their policy message after small tweaks this month upset investors and raised the spectre of surging borrowing costs for the bloc's indebted periphery. 

With inflation at a four-year high, critics of the ECB, particularly in Germany, have called on the bank to start winding down its unprecedented stimulus measures, including a €2.3 trillion asset-buying scheme designed to rekindle growth and inflation. 

"We are not yet sufficiently confident that inflation will converge to levels consistent with our aim in a durable manner," ECB chief economic Peter Praet said, referring to ECB's 2% inflation objective. 

Although euro zone inflation was at 2% year-on-year in February, core inflation remains low. 

Early March inflation figures suggest a dip with Spain dipping to 2.1% from 3% and Germany at 1.5% from 2.2%. 

"Inflation dynamics still remain reliant on the very substantial degree of monetary accommodation which prevails," Praet added. 

The ECB next meets on April 27, before the final round of the French presidential election. A potentially contentious run-off could also encourage the bank to act with caution. 

Arguing for a steady hand, Austrian central bank chief Ewald Nowotny said there was no need to deviate from the already charted course.

Finnish central bank governor Erkki Liikanen also expressed support for the ECB's policy path expressed in its so-called forward guidance. 

"The strategy for 2017 has largely been set and from my point of view there is no reason to depart from this," Nowotny said in Vienna. 

The asset buys are set to run at least until the end of the year and talks about how and when to wind it down have not yet started. 

The sole dissent - and relatively minor - came from Klaas Knot, the Dutch Central bank chief who has opposed many of the ECB's easing measures.

He argued for flexibility, suggesting an earlier end, but only if the economy continues to outperform expectations. 

"Only if the economy does even better than we now expect in our estimates could we consider bringing the tapering forward,” Knot said, referring to the ECB's plans to buy €60 billion worth of bonds each month until the end of the year.
