UPDATE 1-Russia c.bank says sees more rouble flexibility

(Adds Ignatyev quotes, details)

MOSCOW, Nov 10 (Reuters) - The Russian central bank's Chairman Sergei Ignatyev said on Monday he did not rule out more flexibility in the rouble exchange rate and some rouble weakening was possible.

The rouble is under pressure from capital outflows, which Ignatyev said had reached a net of $50 billion in October. The central bank, which runs a managed float of the currency, has been defending the rouble's exchange rate since August.

"I do not rule out more flexibility in the rouble exchange rate with some tendency towards weakening of the rouble against some foreign currencies in the current conditions," Ignatyev told a televised press-conference.

Economists and rating agencies have raised questions over the sustainability of the central bank's policy of defending the rouble which resulted in a $113 billion fall in gold and forex reserves since mid-August.

"It does not make sense to support the rouble when there is no fundamental reason for it to be strong," said Stanislav Ponomarenko, an economist at ING, who expects the central bank to soften its exchange rate policy next year.

The central bank officials until recently maintained they were not planning to change technical parameters of the rouble's trading band against the basket RUS=MCX, made of 0.55 dollars and 0.45 euros.

Ignatyev did not say whether the weakening was possible against the basket as well. The rouble has weakened by 16 percent against the dollar since July 15 peak, tracking the dollar's surge in the forex market. The rouble traded at the weaker end of the trading band, close to the level of 30.41 roubles to the basket seen by the market at the central bank support level. The market was closed when Ignatyev made his remarks after sluggish trade earlier.
