Martin Schlegel, Alternate. Member of the SNB Governing Board , said that the central bank could maintain negative interest rate long term. And there is even scope to cut interest rates deeper into negative territory.
Also, “if the SNB stopped negative rates and went to zero, this would certainly not be good for Switzerland,” he said. “Then we would have a massively strong currency and the yield curve would become inverse or more flat, which is not good for the banking system.”
