SINGAPORE: Indonesian stocks slid to a six-year low on Monday as a warning from MSCI over possible expulsion from its global indexes next year rattled fragile investor sentiment, sharpening the focus on how Jakarta intends to allay the index provider's concerns.

Jakarta's benchmark stocks fell over five per cent in early trading on Monday after plunging 11.6 per cent on Friday, as the world's worst performers reeled from index provider MSCI saying it was considering shifting Indonesia to "standalone" status from its current "emerging markets" mantle.

A shift to standalone status would risk cutting Southeast Asia's biggest economy off from international capital, relegate it to an investment backwater and club it with a group of standalone markets that includes Lebanon and Zimbabwe.
