MOSCOW, January 30/ TASS /. The Capital gain on Russian bonds already includes sovereign rating downgrade risks, head of Central Bank Elvira Nabiulina said on Friday at the State Duma.

"We think that the capital gain of Russian bonds already includes the sovereign rating downgrade risks," Nabiulina said.

The Central Bank of Russian Federation doesn't rule out introduction of a system of maintaining the secondary market of federal loan bonds, its head said.

Almost all Russian banks are working on restructuring foreign currency mortgage, Nabiulina went on to say.

Nabiulina recalled that the Central Bank had recently sent a recommendation to banks on how to restructure foreign currency mortgages at the rate of 1 October 2014, however, she said, the banks developed their own system before the CB recommendations.

The Central Bank of Russia created conditions for the banks to restructure foreign currency mortgage loans and is ready to take new measures, she added.

According to Nabiullina, foreign currency mortgage loans are already 1.5 times more costly for banks as compared to ruble ones.

"We are ready to increase this ratio and make hard currency mortgage loans nearly prohibitive," she concluded.
