The Islamic Financial Services Board (IFSB) issued its 10th research (WP-10) in the IFSB Working Paper series which explores the risk-sharing practices in the Islamic banking sector. It describes the views of both Islamic banks and regulatory and supervisory authorities (RSAs) on the practices of Islamic banks in IFSB member jurisdictions. This is in relation to the governance rights of unrestricted profit-sharing investment account (UPSIA) holders. The findings in WP-10 reveal that the capital treatment of the UPSIA in general varies across different jurisdictions and Islamic banking type. In most of the jurisdictions UPSIAs are considered to be 'investments' exposed to losses rather than 'deposits' with capital certainty.
