FRANKFURT (Reuters) - The European Central Bank kept policy unchanged as expected on Thursday, staying on course to claw back unprecedented stimulus even as the growth outlook continues to darken and political turmoil in Italy looms large over the currency bloc.
Having exhausted much of its firepower with years of support, the ECB reaffirmed that its 2.6 trillion euro ($2.97 trillion) asset purchase scheme will end this year and interest rates could rise after next summer, sticking to a guidance first unveiled in June and repeated at every meeting since.
Acknowledging a weaker recent momentum in the euro zone economy, ECB chief Mario Draghi reeled off what he called a "bunch of uncertainties" related to trade protectionism, emerging markets and financial market volatility.
"Is this enough of a change to make us change the baseline scenario? The answer is 'No'," he told an ECB news conference to justify its policymakers' decision to maintain their judgment that risks remained "broadly balanced".
He added: "The underlying strength of the economy continues to support our confidence that the sustained convergence of inflation to our aim will proceed and will be maintained even after a gradual winding down of our net asset purchases."
Yet despite the hawkish message -- which included an upbeat assessment of firmer wage pressures -- the euro fell on his comment that Europe's monetary union remained "fragile" as long as measures to shore up existing structures were not complete.
"And when I say completed, I mean the banking union, I mean the capital market union," he added of measures initiated as a result of the sovereign debt crisis of almost a decade ago but which have foundered on a lack of consensus among member states.
The single currency slipped 0.1 percent on the day to $1.139 after having earlier reached a session-high of $1.143.
Earlier, the Governing Council statement reaffirmed its view that interest rates would remain at present levels at least "through the summer of 2019". Draghi completed the picture by adding there had been no discussion of extending stimulus.
Policymakers speaking in public and private have said the bar for extending the ECB's bond purchase scheme is very high.
With the EU having taken the unprecedented step of rejecting Italy's budget this week, Draghi was quizzed at length about the escalating political fight between Rome and Brussels over the debt-laden country's expansionary budget.
Himself an Italian, Draghi said he was confident compromise would be reached between Brussels and Rome and noted how much the stand-off was already costing Italy because of the rising yield on its government debt.
Asked about the risk that a fall in the value of Italian government bonds could erode the capital positions of some banks that hold them, he said: "I don't have a crystal ball ... These bonds are in the banks' portfolios. They are denting into the capital position of the banks.
"I'm still confident an agreement will be found," Draghi added.
