European Central Bank (ECB) Governing Council member Jens Weidmann said Wednesday that the central bank's asset-buying programme should not be continued any longer than necessary.

"The expansive monetary policy shouldn't be continued any longer than absolutely necessary," he said.

Weidmann noted that the low inflation is caused by low energy prices and it is temporary.

"I remain of the opinion that monetary policy should look through inflation fluctuations that are caused by energy prices, because these are temporary and the economy benefits anyway through an increase in purchasing power," he said.
