BERLIN — Germany’s finance minister hit hopes that Europe’s stressed banks could soon tap the region’s rescue funds directly when he said Monday that a new Europe-wide banking supervisor is unlikely to be up and running in the new year.

Meanwhile, Chancellor Angela Merkel called on Germans to show “solidarity” with those members of the 17-country euro bloc that are struggling with much-needed economic reforms.

EU leaders agreed in June that funds set up to bail out indebted governments could be allowed to funnel money directly to ailing banks – rather than via governments which would add to their debt burden – once an effective central bank supervision system is established.

The idea is to assuage worries about the health of Europe’s banking system, which is in danger of grinding to a halt as banks become increasingly wary of lending to one another.

The European Commission will make proposals for a new supervisory system Sept. 12. Internal market commissioner Michel Barnier said last week he hopes it could be phased in starting in January and be extended to all eurozone banks by 2014.

Barnier also voiced hopes that banks could be helped directly from Europe’s $629 billion planned permanent bailout fund, starting in January.

But German Finance Minister Wolfgang Schaeuble was skeptical about whether the new system would start work next year.

“I have my doubts that it will come so quickly, and so I think that once again expectations are being created here that can’t be fulfilled, not even close,” Schaeuble told Deutschlandfunk radio.

Germany and the commission already appear at odds on the extent of the new supervisor’s powers. Barnier has argued that all banks need to be supervised centrally by the European Central Bank; Germany argues that the supervisor should limit its focus to major banks whose stability is vital to Europe’s financial security.
