KONTAN.CO.ID, June 19 - Indonesia's rupiah weakened and equities were choppy on Friday after MSCI raised fresh concerns over the country's investability, citing limited visibility in shareholdings and coordinated trading behaviour.

The warning dealt another blow to Indonesia, the world's worst-performing major stock market, coming just days ahead of MSCI decision on whether to downgrade Indonesia to frontier status from emerging market, a move that could trigger $13 billion in outflows.

The rupiah dipped to 17,850 per U.S. dollar, nearing a one-week low.
