Indonesia's regulator has issued revised Islamic banking rules covering asset quality and capital adequacy to help clarify market practices, while industry growth has now dropped to single-digits. Indonesia's financial services authority, Otoritas Jasa Keuangan (OJK), announced the move on Wednesday as part of a package of 20 new rules, which range from corporate governance to microfinance. Authorities want Islamic banks to hold at least 15 percent of the market by 2023, but the sector's growth is stalling. As of September, there were 11 full-fledged Islamic banks and 23 Islamic business units in Indonesia with combined assets of 244 trillion rupiah ($20.1 billion), representing a 7.2 percent growth year-on-year.
