Understanding Riba in Modern Finance

March 30, 2026 · 1 min read

Riba (interest/usury) is one of the most clearly prohibited elements in Islamic finance. Understanding where it appears in modern systems is essential for informed investing.

Riba in Banking

Conventional banks operate on an interest-based model. They pay interest on deposits and charge interest on loans. This is the most visible form of riba in daily life.

Riba in Bonds

Conventional bonds are fundamentally interest-based instruments. The bondholder lends money and receives fixed interest payments. This structure is why most Islamic finance scholars consider conventional bonds impermissible.

Riba in Corporate Finance

Even non-financial companies interact with riba through:

  • Corporate debt: Loans from banks carry interest
  • Cash deposits: Company cash held in interest-bearing accounts
  • Credit terms: Some business arrangements involve implicit interest

Why Screening Checks for It

This is why financial ratio screening exists — to measure how much a company is entangled with interest-based finance, even if its core business is permissible.

The Scholarly Basis

The prohibition of riba is mentioned in multiple verses of the Quran (2:275-279, 3:130) and numerous hadith. The consensus among major Islamic scholarly bodies is that it applies to modern interest in all its forms.
