* MSCI world equity index down 1 percent to 250.18
* Dollar rises after G8 on Russia, IMF comments
* Oil falls 1.6 pct, weighing on energy, commodity shares

LONDON, June 15 (Reuters) - The dollar rose across the board on Monday after Russia said the U.S. currency's role as the world's main reserve currency was unlikely to change in the near future, hitting energy and commodity prices and related shares.
After a weekend meeting in southern Italy, finance chiefs from Group of eight said they believed their economies are stabilising but recovery from the credit crisis remained shaky. Ministers also said they have started to consider how to unwind rescue steps for their economies once recovery is certain.
While the G8 communique made no reference to the dollar, Russian Finance Minister Alexei Kudrin said on the sidelines of the meeting that the dollar's role as the main reserve currency was unlikely to change in the near future.
IMF managing director Dominique Strauss-Kahn told Reuters in an interview at the G8 that the dollar has been correctly valued by the market. The U.S. currency's strength weighs on energy and commodity prices as they are priced in dollars.
"The dollar is stronger across the board and this is predominantly to do with the comments made by Russia's finance minister at the G8," said Michael Klawitter, senior currency strategist at Dresdner Kleinwort in Frankfurt.
The dollar <.DXY> rose 0.8 percent against a basket of major currencies while the euro fell 0.7 percent to $1.3879 <EUR=>.
Kudrin's remarks came ahead of the first summit of leaders of Russia, China, India and Brazil on Tuesday in the Russian city of Yakaterinburg, at which the leaders are expected to discuss issues including foreign reserve diversification.
COMMODITIES PRESSURED
Shares of mining and oil shares led the move lower in world stocks. MSCI world equity index <.MIWD00000PUS> fell 1 percent, moving further away from a 7-1/2 month high hit earlier this month.
"While there is a sense of optimism, there are also questions about whether economic indicators have really recovered to where they were before," said Daisuke Uno, chief strategist at Sumitomo Mitsui Banking Corp in Tokyo.
The benchmark MSCI index finished last week on a positive note, posting the third consecutive weekly gains.
The FTSEurofirst 300 index <
> fell 1.6 percent.Emerging stocks <.MSCIEF> also lost 1.6 percent.
U.S. crude oil <CLc1> dropped 1.6 percent to $70.90. Shanghai copper fell by its 5 percent limit and London futures broke below $5,100 a tonne.
"Stabilising dollar outlook could trigger a mini chain reaction which might look like setting the starting point for a new equity bear market," BNP Paribas said in a note to clients.
"Indeed, the stabilising dollar will take the momentum out of the speculatively over-extended commodity market, causing related currencies to decline. The dollar will receive additional support via this liquidation effect."
The June bund futures <FGBLc1> hit a one-week high of 119.06 as equity markets fell.
