Russia's Central Bank Governor Elvira Nabiullina told lawmakers on Thursday that she had been doubtful about the effectiveness of imposing mandatory foreign currency sales for exporters as companies can repurchase the FX revenues they sell.

The government late on Wednesday said President Vladimir Putin had signed a decree reintroducing capital controls for an undisclosed list of 43 exporting firms, a measure that has been on the cards since the rouble tumbled into triple digits in August.

Nabiullina said there were no contradictions between her position and that of the president. The central bank said earlier on Thursday that the targeted nature of the restrictions would be important. Nabiullina said the measures were temporary and their effectiveness would be monitored. (Reporting by Elena Fabrichnaya; Writing by Alexander Marrow Editing by Gareth Jones)
