I still wait for the forwarded newspaper report. But just heard a story from a colleague that an official of Bank Indonesia's sharia division recently appealed that the customers of sharia banks should remain 'loyal,' and not to move their funds to the conventional banks. This appeal was made after the interest rate (of the conventional banking system) rose, following the increase of inflation, making it more INTERESTing to save in the conventional banks.
'Iman' is one thing. But at the end, it's the incentives that matter, no...?
