Indonesian business tycoon Tahir is keen to gain control of PT Bank Permata, a larger rival to his PT Bank Mayapada International, as he seeks to put his lender in the ranks of the nation’s biggest banks. Tahir’s Mayapada Group wants to buy the 90 percent of Permata that is owned by Standard Chartered Plc and PT Astra International and merge it with Bank Mayapada to create Indonesia’s largest non-government bank by assets after PT Bank Central Asia, he said.
