Islamic guidance on forex and crypto trading

The basic principle in Islam is that all financial transactions are permissible unless they contain a prohibition established by Sharīʿah. Therefore, if a transaction involves ribā (interest), excessive uncertainty (gharar), gambling (maysir), deception, or any other Sharʿī prohibition, it becomes impermissible.

Allah Most High says:

 ﴿وَأَحَلَّ اللَّهُ الْبَيْعَ وَحَرَّمَ الرِّبَا﴾

“Allah has permitted trade and prohibited interest.” (Surah al-Baqarah 2:275)

The Messenger of Allah ﷺ also said:

 «الذَّهَبُ بِالذَّهَبِ، وَالْفِضَّةُ بِالْفِضَّةِ... يَدًا بِيَدٍ»

“Gold for gold and silver for silver… must be exchanged hand to hand (with immediate possession).” (Sahih Muslim, Hadith: 1587)

This hadith forms the basis for the Sharʿī requirement of immediate possession (qabḍ) in currency exchange (ṣarf).

First: Forex Trading

Retail online Forex trading generally contains one or more of the following Sharʿī violations:

Interest-based (swap) transactions.

Margin or leveraged trading.

Buying and selling currencies without valid Sharʿī possession (qabḍ).

Speculation based solely on price fluctuations.

For these reasons, the retail Forex trading commonly practiced today is not permissible according to Islamic law.

Second: Cryptocurrency

The cryptocurrencies commonly traded today also involve a number of significant Sharʿī concerns, including:

Excessive uncertainty (gharar).

Highly speculative trading resembling gambling (maysir).

Extreme price volatility.

Characteristics that make them predominantly instruments of speculation rather than genuine mediums of exchange or real economic activity.

For these reasons, many leading contemporary Islamic jurists have ruled that trading the cryptocurrencies currently in circulation is not permissible.

Juristic Principle

 الأصل في المعاملات الإباحة، إلا ما دل الدليل على تحريمه

“The fundamental rule regarding financial transactions is permissibility, except where there is evidence establishing prohibition.”

Therefore, when a financial transaction contains ribā, gharar, maysir, or other Sharʿī prohibitions, it no longer remains under the original presumption of permissibility.
