Nearly a Quarter of Bangladesh's Banking Deposits Are Now Islamic

By January 2026, Islamic banks in Bangladesh held total deposits of Tk 4,74,000 crore — a 9.34 percent increase year-on-year, and 22.34 percent of all deposits in the country's banking system.

Nearly one taka in every four held in a Bangladeshi bank now sits in a Shariah-compliant institution.

The Scale

• Tk 4,74,000 crore in deposits, 22.34 percent market share.
• Tk 5,85,000 crore in total investments including sukuk — up 11.07 percent on January 2025.
• 1,741 branches and 976 Islamic banking windows within conventional banks.
• 45,061 employees.
• Mudarabah profit-sharing arrangements account for 87.26 percent of Islamic deposits.

The window model is worth noting. Conventional banks operating 976 Shariah-compliant windows means the growth is not confined to dedicated Islamic banks — mainstream institutions have concluded there is enough demand to justify running parallel products.

How the Model Differs

Islamic finance prohibits riba — interest — and requires that returns derive from real economic activity and shared risk rather than from lending money at a fixed price.

In practice, a Mudarabah depositor is a partner rather than a creditor: the bank invests the funds and shares actual profits according to a pre-agreed ratio, and a loss is borne by the depositor rather than guaranteed away. That 87.26 percent of deposits sit in this structure indicates genuine adoption of the model rather than conventional products relabelled.

Sovereign Sukuk: Bonds That Build Things

The government has raised Tk 19,000 crore through four separate sovereign sukuk issuances to date, with more than Tk 6,000 crore (around $550 million) in further issuance planned for 2026.

The distinguishing feature is that these funds are tied to specific infrastructure projects. A conventional government bond raises money into general revenue; a sukuk must be backed by identifiable assets or projects, because returns have to derive from real economic activity rather than interest.

That structure produces an unusual side-effect: it enforces transparency about what borrowed money is being spent on. For a government financing the infrastructure programme covered across this site — Delta Plan works, waterway restoration, roads and power — asset-linked instruments are a natural fit.

Why This Matters Internationally

Global Islamic finance assets run into the trillions, concentrated in the Gulf and Malaysia. Institutional investors in those markets face a persistent shortage of Shariah-compliant instruments to allocate to.

Bangladesh — the world's third-largest Muslim-majority population, running a large infrastructure programme and issuing sovereign sukuk — is a natural destination for that capital. It connects directly to the deepening relationship with Gulf partners this publication has covered, including Bangladesh's inclusion in the Mecca Pact.

The domestic implication matters too. A financial system offering Shariah-compliant products brings savers into the formal banking system who would otherwise hold cash — which, alongside the mobile financial services revolution, is one of the two main channels of financial inclusion in Bangladesh.

What to Watch

Two questions will determine the sector's trajectory.

Governance. Bangladesh's banking sector as a whole has faced significant scrutiny over asset quality and governance, and Islamic banks are not exempt from that. Shariah compliance is a distinct question from prudential soundness, and investors should assess both separately.

Sukuk market depth. Four sovereign issuances is a start, not a market. A liquid secondary market and corporate sukuk issuance would be the signals that this has matured from a government funding tool into a genuine capital market.
