IFSB

Islamic Financial Services Board. An international standard-setting organization based in Kuala Lumpur, Malaysia, established in 2002. While AAOIFI sets Shariah and accounting standards for institutions, IFSB sets prudential and supervisory standards for the regulators that oversee them - covering capital adequacy, risk management, governance, and stress testing for Islamic banks, takaful operators, and Islamic capital markets.

Its members include central banks and financial regulators from more than 80 jurisdictions. AAOIFI and IFSB are complementary: AAOIFI tells institutions how to operate; IFSB tells regulators how to supervise them.

The Islamic Financial Services Board (IFSB), headquartered in Kuala Lumpur since 2003, is the prudential counterpart to AAOIFI: while AAOIFI writes contract-level Shariah and accounting standards, the IFSB writes regulatory standards - capital adequacy, risk management, stress testing, and supervisory review - adapted from Basel frameworks for institutions that cannot simply hold interest-bearing instruments as capital buffers. Its membership includes central banks and regulators from over 50 jurisdictions.

U.S. consumers rarely interact with IFSB standards directly because American regulators supervise Islamic finance providers under conventional banking and consumer-protection law, not IFSB frameworks. The IFSB matters to Americans mainly through Sukuk and international Islamic funds: when a U.S. investor buys into a global Sukuk fund, the issuing banks abroad are typically regulated under IFSB-derived capital rules, which shapes the risk profile of what ends up in the portfolio.

The IFSB also publishes the annual Islamic Financial Services Industry Stability Report, one of the most-cited data sources on the size and health of the roughly $3-4 trillion Islamic banking sector.
