Can a global financial system operate entirely without the concept of interest?

In short: Islamic finance prohibits riba, or interest, viewing it as exploitative. Instead, it promotes profit-sharing and asset-backed transactions. While modern Islamic banking has grown into a multi-trillion-dollar industry, critics argue it often mimics conventional banking, using complex legal structures to replicate the very interest-based outcomes it claims to avoid.

At the heart of Islamic finance is the rejection of riba, a term encompassing interest, usury, or any unearned excess on a loan. Proponents argue this creates a more ethical, stable economy where risk and profit are shared between the financier and the entrepreneur. Historically, this approach traces back to early Islamic practices, such as those of Zubayr ibn al-Awwam, who managed deposits through business investments rather than interest-bearing loans. While some scholars maintain that all interest is forbidden, others, including historical modernists like Syed Ahmad Khan, have distinguished between sinful usury on consumption loans and legitimate commercial interest.

The modern movement emerged in the mid-20th century, notably with Ahmad Elnaggar’s 1963 experiment in Mit Ghamr, Egypt. By the 1970s, fueled by the 1973 oil crisis and a broader Islamic revival, the sector expanded globally. Today, the industry is substantial, with total Sharia-compliant assets estimated between US$3.88 trillion and US$5.98 trillion as of 2024. Institutions like the Islamic Development Bank (1975) and the development of sukuk—Islamic alternatives to conventional bonds—have provided the infrastructure for this growth, attracting interest from both Muslim-majority nations and Western hubs like Luxembourg and the UK.

Despite this success, the industry faces significant internal critique. Many scholars, such as M.T. Usmani, argue that banks have failed to adopt the promised profit-and-loss sharing models, relying instead on debt-based contracts like murabaha (cost-plus financing). Critics contend these products often use legal ruses to conceal interest, effectively mirroring the conventional banking they seek to replace. Furthermore, while Islamic banks avoided the 'toxic assets' of the 2008 financial crisis, they remained vulnerable to the subsequent collapse in real estate and private equity valuations, highlighting the ongoing tension between religious ideals and the realities of global capital markets.
