Banks: PT Bank Mandiri (BMRI IJ), Indonesia's biggest bank by assets, declined 2.3 percent to 6,250 rupiah. PT Bank Central Asia (BBCA IJ), the second largest, slipped 1.5 percent to 6,600 rupiah. Lenders fell amid concerns the debt crisis in Europe will prompt investors to sell assets in high-yielding markets and that the shares' rally this year was excessive relative to their earnings outlooks, according to Andrew Siahaan, an analyst at PT Reliance Securities.
