Why I don't support Islamic Banking

Many people assume that if you criticize Islamic banking, you must be against Islamic finance. My position is the opposite. The more I study finance and the behavior of real investors, the more convinced I become that modern Islamic banking misunderstands the original philosophy behind Islamic finance.

To me, the problem is not riba itself. The problem is how Islamic banking claims to solve it.

The prohibition of riba

The prohibition of riba in Islamic law is clear. Classical jurists defined riba as any guaranteed increase on a loan. That definition has been consistently recognized across the major schools of Islamic jurisprudence, and I am not attempting to reinterpret it. But understanding the rule alone is not enough. To understand why Islamic finance developed the way it did, we need to look at the economic environment where these principles emerged.

The original context of Islamic finance

Islamic commercial law developed in a trading world. Early Muslim societies were deeply involved in commerce across regions stretching from the Mediterranean to Central Asia and the Indian Ocean.

Financial relationships in that environment often revolved around trade and partnership, not institutional lending.

Classical contracts such as mudarabah and musharakah illustrate this.

In a mudarabah, one party provides capital while the other manages the business. Profits are shared according to agreement, while losses fall on the capital provider unless there is negligence or misconduct.

In a musharakah, multiple partners contribute capital and share profits and losses together. These structures tie financial returns directly to real economic activity. Capital is invested in enterprise rather than lent out for guaranteed profit.

Loans certainly existed historically, but they were not intended to become profit-generating instruments. The prohibition of riba reinforced that distinction.

Centuries earlier, Ibn Khaldun made a related observation in the Muqaddimah: wealth ultimately comes from productive activity such as trade, labor, and enterprise. Financial arrangements that merely circulate money without supporting real economic activity contribute little to long-term prosperity.

In other words, Islamic finance historically encouraged participation in productive enterprise, not income from lending money. The question, then, is how these principles translate into a modern financial system that operates very differently from the trading world in which they developed.

The modern financial system

The economic world today looks very different from the one where these contracts developed. Modern economies rely heavily on credit markets. People borrow money not just for business activity but for housing, cars, education, and many other personal expenses.

These are not entrepreneurial ventures. They are ways of spreading large costs over time. Because of this, modern financial institutions are structured primarily around debt contracts. Banks exist largely to provide safe deposits and extend credit.

This is where the tension with classical Islamic finance begins.

Where theory and practice diverge

Islamic banks operate inside this credit-based financial system.

To avoid riba, financing is often structured through contracts such as:

• murabaha (asset purchase and resale at a higher deferred price)
• ijarah (leasing arrangements)
• tawarruq (commodity transactions used to generate liquidity)

These contracts may satisfy formal legal requirements within Islamic jurisprudence.

However, economically they often produce outcomes that look very similar to conventional credit. Financing is provided and a larger amount is repaid over time.

From my perspective, this creates a gap between legal structure and economic substance.

The industry claims to avoid riba, yet much of the system still revolves around debt-like transactions rather than genuine partnership financing.

Human behavior complicates everything

Even if the legal structures are correct, another reality complicates the picture: human behavior.

Over the years I have sold millions of dollars in financial investments. One lesson becomes obvious very quickly. People say they accept risk, but they rarely tolerate losses.

Even when a product is clearly explained as high risk, investors become uncomfortable the moment their principal declines. If someone invests $10,000 and later sees $9,000 on their statement, panic often follows.

Because of this, portfolios are usually structured carefully. A typical allocation might include:

• bonds for stability
• guaranteed instruments for psychological security
• equities for long-term growth

Even the equity portion often focuses on relatively stable industries.

This is not just about investment strategy. It is about managing human reactions to financial loss.

Money makes people irrational.

The tension inside Islamic banking

Islamic finance emphasizes risk sharing and participation in enterprise.

Modern savers, however, want stable balances and predictable returns. These expectations do not easily coexist.

As a result, Islamic banks often design structures that technically comply with contractual requirements while still delivering the stability customers expect from conventional banking.

The outcome is a system that frequently resembles conventional credit, even while claiming to avoid riba.

The deeper mismatch

The issue, in the end, is not simply about terminology or contracts.

It is about the gap between a financial philosophy built around partnership and shared risk and a modern economy built around consumer credit and capital protection.

As long as most people prefer stable savings and predictable obligations, financial institutions will naturally gravitate toward credit-based structures.

Why I remain skeptical

For these reasons, I do not support Islamic banking in its current form.

The issue is not with the prohibition of riba itself. That principle remains clear within Islamic law.

The issue is that the modern industry often presents itself as a solution while operating in ways that closely resemble the lending structures it aims to replace.

Islamic finance contains powerful ideas about entrepreneurship, partnership, and shared risk.

But trying to fit those ideas into a financial system built primarily around credit and capital preservation inevitably creates tension.

Until that tension is acknowledged openly, the gap between theory and practice will remain.
