The adjustment redefines that no special weights can be used for short-term claims vis-à-vis systemically important cantonal banks.
This is a direct result of the SNB's recent announcement that the Zürcher Kantonalbank is now regarded as a systemically important bank. The said change enters into force on 1 January 2014 and must be complied with by 31 March 2014 at the latest. Also by this deadline, banks must adhere to the upper limit for a large exposures as specified in the Capital Adequacy Ordinance (Art. 97).
