Nowadays, most of the giant international banks provide either an Islamic Commercial Bank (ICB) or an Islamic Business Unit (IBU).
A report named “Islamic Banking Statistics April 2011”, which was launched by Bank Indonesia (BI) on June 15, 2011, found that ICB increased from only three banks with 304 offices in 2005 — when Islamic banking was born — to 11 banks with 1,215 offices by December 2010.
The number of IBU became larger, from 19 units with 154 offices in December 2009 to 23 units with 262 offices in December 2010. The current total of IBU remains unchanged at 23 units.
