Optimal regulatory design for the Central Bank of Russia

The Central Bank of Russia (CBR) assumes a wide range of functions not raditional to a central bank. In addition to the daily conduct of monetary policy, it acts as a regulator and supervisor of the banking sector. It is currently overssing the implementation of a deposit insurance scheme and is the main owner of Russia's largest commercial bank, Sberbank. As this additional functions may conflict with the CBR policy objectives, I review how the current design of the CBR deviates from the optimal allocation of regulatory powers within a central bank prescribed in the literature. I then empirically investigate the need for a supervisory body within the CBR. Using a simple Taylor rule framework I find that the CBR does not use its "hands-on" supervisory information to maintain financial stability, but rather to accomodate state-owned banks' balances.
