AMSTERDAM (Reuters) – Conservative policymakers slammed the European Central Bank’s lavish stimulus measures on Friday, voicing doubts about the need and effectiveness of a package that could consume most of the bank’s remaining firepower. Facing a protracted growth slowdown, the ECB cut rates deeper into negative territory on Thursday and relaunched fresh bond purchases with no scheduled end-date, a move that divided the normally collegial Governing Council. Although no vote was taken, sources with direct knowledge of the discussion said that over a third of policymakers opposed the fresh asset buys, pushed by outgoing ECB chief Mario Draghi, an unusually high figure for a body that normally strives for consensus. “This broad package of measures, in particular restarting the asset purchase program, is disproportionate to the present economic conditions, and there are sound reasons to doubt its effectiveness,” Dutch central bank chief Klaas Knot, a frequent critic of the bank’s ultra-easy monetary policy, said. While disagreements are frequent, ECB policymakers usually line up behind decisions and refrain from openly criticizing its policy. Bundesbank President Jens Weidmann, another key critic, also said the stimulus was excessive, and Thursday’s decisions indicated that rates will stay low for a long time. Germans have been especially irked by negative ECB rates and mass-selling newspaper Bild portrayed Draghi as “Count Draghila,” a blood sucking vampire, who is sucking dry the bank accounts of German savers. Knot said the euro zone economy is running at full capacity, wages are increasing and that financing conditions are so easy, they do not impede the flow of credit. “There are increasing signs of scarcity of low-risk assets, distorted pricing in financial markets and excessive risk-seeking behavior in the housing markets,” added Knot, a member of the ECB’s policy-setting Governing Council. Austrian central bank chief Robert Holzmann, meanwhile, said he was worried the ECB had made a mistake and that such a broad package should not have come before the bank’s planned policy review, which could even see the inflation target lowered.

So there is no need to … use all the power you have in order to move up to 2% if the cost is too high,” he added, referring to the ECB’s inflation target of just below 2%. Providing a counterpoint to the hawks, Slovenian central bank chief Bostjan Vasle said the ECB remained ready to do even more if needed, as growth and inflation were both weak.
