The stack overflows, but the theory holds.
On 14 March 2025, a fatwa from the Council of Islamic Ideology (CII) in Pakistan concluded that using cryptocurrencies for purchases is haram. The judgment was not a surprise to anyone who had traced the mathematical invariants of Islamic finance: the presence of riba (interest) and gharar (excessive uncertainty) in most crypto assets violates the core axioms of Sharia. But the news that broke two days later — that the Pakistan Virtual Assets Regulatory Authority (VARA) would restart dialogue with the CII — introduced an edge case into the otherwise deterministic logic.
Here is the contradiction: a regulator that had been preparing a licensing framework for digital assets is now forced to reconcile with a theological ruling that delegitimizes the very asset class. The market reaction was predictable — a 12% drop in peer-to-peer Bitcoin premiums on local exchanges — but the deeper implication is far more interesting. This is not just a Pakistan story. It is a stress test for the entire concept of Sharia-compliant crypto, and it reveals a fundamental flaw in how the industry has approached religious regulation.
Context: The Two Layers of Authority
To understand the gravity of this event, you must first understand the dual governance structure of Pakistan’s crypto space. There is the secular regulator (VARA, established in 2023 under the State Bank of Pakistan) which has been drafting a regulatory sandbox for virtual asset service providers. And there is the constitutional body (CII) whose fatwas, while not legally binding, carry enormous social weight. In a country where 96% of the population is Muslim, a ruling from the CII effectively sets the boundary of permissible economic activity for the majority.
The CII’s position is not new. In 2018, they issued a similar fatwa against Bitcoin, but at that time the market was negligible. By 2025, Pakistan had become one of the top 10 countries in global crypto adoption, with an estimated 15 million users, most of whom rely on peer-to-peer trading because local banks refuse to deal with exchanges. The fatwa this time was more specific: it targeted the use of crypto as a medium of exchange, not as an asset. This nuance is critical, but poorly understood.
The regulatory dialogue that VARA initiated is an attempt to thread the needle. They are asking the CII to clarify whether a Sharia-compliant token — one that is fully backed by real assets, does not involve interest, and has no speculative premium — could be exempted. My own experience auditing smart contracts for Islamic banks in Malaysia and Indonesia has shown me that such a token is mathematically possible but operationally fragile. The invariant of a truly Sharia-compliant token requires that its price never deviate from the underlying asset by more than a predetermined spread, which is difficult to enforce on-chain without an oracle solution that itself must be Sharia-compliant. The CII has not yet answered.
Core: Decomposing the Sharia Invariant
Let me formalise the problem. Islamic finance rests on three prohibitions:
- Riba: Any guaranteed return on capital, including interest, is forbidden.
- Gharar: Excessive uncertainty or ambiguity in a transaction is forbidden.
- Maysir: Gambling or pure speculation is forbidden.
A standard cryptocurrency like Bitcoin fails the gharar test because its price volatility introduces uncertainty that exceeds the threshold accepted by most scholars. A stablecoin like USDT fails the riba test because its issuer holds interest-bearing reserves. A DeFi liquidity pool fails all three: the yield is often derived from transaction fees (which may involve interest-based products), and the impermanent loss risk is a form of gharar.
The CII’s ruling essentially performed a logical deduction:
