Bagi bank syariah yang beroperasi dengan prinsip bagi hasil, keberhasilan dalam manajemen aset liabilitas sangat ditentukan oleh kualitas aset. Kebijakan pembiayaan, sebagai bagian dari aktifitas manajemen aset liabilitas, berperan memberikan arah atau pedoman dalam kegiatan kredit dalam rangka tercapainya tujuan penyaluran kredit, yakni memaksimalkan laba dan meminimalkan risiko. Tercapainya tujuan tersebut akan tercermin dari kualitas aset.Kualitas aset akan menentukan bonus dan bagi hasil yang diberikan kepada nasabah penyimpan dana dan selanjutnya, akan menentukan kemampuan bank untuk menghimpun dana. Hal sedemikian tidak berlaku bagi bank konvensional, dimana imbalan kepada nasabah penyimpan dana didasarkan pada suku bunga yang telah ditentukan terlebih dahulu tanpa mempertimbangkan kualitas aset.Diversifikasi pembiayaan merupakan implementasi dari kebijakan pembiayaan (kredit) khususnya kebijakan dalam menentukan target pembiayaan (kredit), berupa, jumlah, jenis (types) dan komposisi dari pembiayaan (kredit) yang disalurkan kepada masyarakat. Dengan mendiversifikasi pembiayaan, bank syariah melakukan diversifikasi risiko dengan cara menyalurkan pembiayaan dalam berbagai dimensi, antara lain, jenis usaha, jenis produk, jenis maturitas dan lokasi.
