What is AAOIFI's ruling on Bitcoin and cryptocurrency?

AAOIFI (the Accounting and Auditing Organization for Islamic Financial Institutions) publishes the Shariah standards that most Islamic banks and halal investment platforms follow, including Shari'a Standard No. 21 on financial paper, which governs stock screening. Digital assets have been discussed at AAOIFI conferences and working sessions, and AAOIFI accounting standards are already referenced in regional digital asset regulations such as Bahrain's stablecoin framework. A dedicated, final Shariah standard on cryptocurrency, however, has not been issued. Any article citing a specific 'AAOIFI cryptocurrency ruling' should be read with that in mind.

In the absence of a binding standard, Muslim investors look to individual scholars and fatwa bodies, and their conclusions differ. Among Sunni authorities, Mufti Muhammad Taqi Usmani, one of the most respected contemporary voices in Islamic finance, has taken a cautionary position: he considers cryptocurrency trading impermissible in its current form because it is dominated by speculation rather than use as a genuine medium of exchange, while leaving the door open to revisiting the ruling if crypto becomes tied to real economic activity. Egypt's Dar al-Ifta issued a fatwa under Grand Mufti Shawki Allam in 2017 prohibiting dealing in Bitcoin, citing excessive uncertainty (gharar) and the absence of a recognized issuing authority.

Among Shia authorities, the office of Grand Ayatollah Sayyid Ali al-Sistani advises precaution on digital currencies. In his published guidance, buying, selling, and activities related to virtual currencies such as Bitcoin are a matter on which he withholds a ruling, and followers are directed to refer to the next most learned jurist on this question. His office also emphasizes that where local law regulates or restricts cryptocurrency trading or mining, those laws must not be violated.

Other scholars and Shariah boards permit spot ownership of major cryptocurrencies with conditions: the asset must have a real use case, the transaction must be immediate rather than leveraged or interest-bearing, and the coin must not be designed for prohibited activity. This is the approach behind most 'halal crypto' lists, and it is the approach HalalScreener's crypto screening follows. Each coin is assessed on what it actually does: its function, the project behind it, and how it is used, rather than treating all cryptocurrencies as one ruling.

For a Muslim investor, the practical takeaway is threefold. First, verify the source of any claimed AAOIFI ruling, because no final AAOIFI cryptocurrency standard exists yet. Second, decide which scholar or methodology you follow, and apply it consistently. Third, if you follow a scholar who permits crypto with conditions, screen each coin individually instead of assuming the whole asset class is halal.
