The head of the Russian central bank says he’s looking into changing the rules on how much money can be traded.

(Reuters) – A central bank official said on Thursday that Russia is looking into changes to its foreign exchange controls to avoid situations where the rouble exchange rate on the shadow market doesn’t match up with official rates.

“We are looking into how to make it easier for importers to buy (foreign currency) on the course, for those who want to learn about FX.”

Trying to figure out how to change the rules already in place is what the central bank is looking for right now.
