Vasle, who just ended an 11-year stint as the head of the government's macroeconomic think tank IMAD, spoke of pending changes, both in the international economic environment and in the coordination and oversight of policies, conducted by the ECB and by extension Banka Slovenije.

"In this process Banka Slovenije needs to build its positions on expert arguments and present these positions publicly, not only within the euro system, but to the wider public, which encompasses experts, politics as well the general interested public," he said.

While speaking of the need for effective coordination of policies in the face of the pending calming of growth, Vasle described the situation on the banking market as relatively good, with banks being in better shape than before the crisis.

He expects new risks and challenges as regards macro-prudential policy, saying "different segments of the financial market will have to be connected".

Vasle expects a period that will show how successful the institutional changes in the euro area have been.

He called for the banking union to be completed as soon as possible, as this would "contribute to even more stability", which is particularly important for Slovenia as a small and open economy that is exposed to shocks.

The ECB is facing a reflection on how to gradually withdraw unconventional measures, Vasle said, while noting that quantitative easing had played a key role for stability. Future steps will determine development and expectations.

Meanwhile, turning to legal dilemmas regarding the crisis bailout and bail-in, he announced Banka Slovenije would help draw up a bill that would secure legal protection. He called for this to be resolved as soon as possible.

As regards the possibility to have the Court of Audit scrutinise Banka Slovenije's decisions, he said he was in favour of oversight but that this would also require bridging discrepancies between Slovenian and eurozone legislation.
