Slamming Draghi for “overshooting the mark”, Bundesbank chief Jens Weidmann told Bild daily that “such a far-reaching package was not necessary”.
ECB governors on Thursday pushed the deposit interest rate further into negative territory and relaunched net purchases of government and corporate debt.
But the deep split among the central bankers burst into the open a day after Thursday's monetary policy meeting.
Around 10 of the 25 members of the ECB governors were against relaunching the quantitative easing programme of purchasing 20 billion euros ($22 billion) worth of debt monthly from November, sources told AFP.
Ahead of the meeting, several eurozone central bankers, including Weidmann, had openly warned against unleashing a new round of stimulus so swiftly.
“This decision to buy more public debt will make it harder for the ECB to exit from this policy. The longer (such policies) last, the more the side effects and financial stability risks of the very expansive monetary policy will grow,” warned the German central banker.
He also noted that at the losing end of the expansionary policy are millions of savers, who will see the value of their holdings dwindle in banks.
Separately, the head of the Dutch central bank, Klaas Knot, issued a statement saying the “broad package of measures… is disproportionate to the present economic conditions, and there are sound reasons to doubt its effectiveness”.
Knot, like Weidmann a hawkish member of the ECB's governing council, said there was no need for the measures when the “euro area economy is running at full capacity”.
“Neither is there a risk of deflation, nor are there any signs pointing to a euro area-wide recession. The only observation is currently that the inflation outlook lags behind the ECB's aim,” he said.
The highly unusual open criticism was noted by the analysts, who pointed out that while it was not uncommon for central bankers to give interviews after a monetary policy meeting to air their views, Knot's decision to issue a full-blown statement was “a clear first”.
Draghi had pointed to three reasons for the ECB's heavy hand in September: data and surveys showing the eurozone economy already slowing, looming threats such as protectionism and Brexit, and downward revisions to the bank's
The ECB's “big bang” blast of measures has touched a nerve particularly in Europe's biggest economy — a nation of savers and a fast-ageing society where the government's mantra has been to keep its budget balanced in preparation for rising pension and health outlays in the coming decades.
Publishing a doctored photo of Draghi with sharp teeth, Bild daily had headlined their story: “That's how Count Draghila is sucking our accounts dry.”
The outrage also cut across to centre-left media, with the Tagesspiegel broadsheet slamming Draghi's latest salvo as “horror policy”, warning that it served neither savers and pension funds nor life insurers.
Rather, it warned that the cheap money was keeping afloat “zombie firms” that should have gone bust under normal circumstances.
Likewise, Süddeutsche newspaper said that while Draghi had in his eight years in office saved the eurozone with his bold action, “Thursday's decisions show that he has now lost his way”.
Frankfurter Allgemeine Zeitung daily meanwhile noted that Draghi is leaving behind a “deeply divided” council to his successor Christine Lagarde, who will take over after he hosts a last monetary policy meeting in October.
Draghi's salvo on Thursday had also grated on Germans, as he had put the onus on governments with budgetary slack to act and help lift the economy.
While Draghi did not name Germany, calls have grown internationally on the EU economic giant, which has been running up huge surpluses, to loosen its purse strings.
Amid the recriminations, Finnish central banker Olli Rehn praised the ECB's action and called for unity.
In an interview with Bloomberg news, he reminded colleagues that it was “important that we maintain unity in public appearances and that's why I think it's important that we defend this very good decision.”
