Islami Bank Bangladesh once had an NPL ratio below 3%. By September 2025, it carried over Tk 1 lakh crore in bad loans — and a non-performing loan ratio north of 35%. The stock price tells only part of that story. The NPL ratio told the whole thing years earlier.
If you are evaluating banking stocks on the DSE, you have probably looked at earnings per share, return on equity, and dividend yield. Those metrics measure what a bank earned last quarter. The NPL ratio measures whether it will keep earning next quarter — or whether a wall of bad loans is about to consume its profits.
Bangladesh’s banking sector carries an industry NPL ratio of 24.1% as of March 2025, the highest in the world. But that average masks enormous dispersion. Some DSE-listed banks sit below 2%. Others exceed 35%. That gap is where investment decisions are made — and where mistakes are most expensive.
The Formula and What It Actually Measures
NPL Ratio = (Gross Non-Performing Loans ÷ Total Gross Loans) × 100.
A loan becomes non-performing when the borrower misses scheduled payments — typically 90 days past due. The ratio tells you what share of a bank’s total lending book has gone bad. A bank with Tk 10,000 crore in loans and Tk 500 crore classified as non-performing has a 5% NPL ratio.
Simple arithmetic. But the implications cascade. High NPLs force higher provisioning, which eats into net profit, which reduces dividends, which erodes the price-to-earnings ratio the market assigns to the stock. A bank reporting strong revenue while its NPL ratio climbs is a bank whose reported profits are borrowed time.
That distinction matters more on the DSE than almost any other exchange in the world — because 24.1% is not a normal operating environment.
Benchmarks That Actually Work for Bangladesh
Global banking benchmarks are useless here without context. The US banking sector runs at 1.5% NPL. India sits at 1.9%. Applying those standards to the DSE would disqualify nearly every listed bank. Instead, use these DSE-calibrated tiers:
| NPL Range | Signal | Investor Action |
|---|---|---|
| Below 2% | Outstanding asset quality | Core holding candidates |
| 2–3% | Healthy — sector best | Strong fundamentals, evaluate growth |
| 3–5% | Manageable risk | Acceptable with adequate provisions |
| 5–10% | Elevated risk | Caution — check capital adequacy |
| 10–20% | Significant asset quality issues | High risk — potential profitability drag |
| Above 20% | Crisis-level stress | Avoid or extreme caution |
Only 17 out of 51-plus private banks in Bangladesh maintain NPLs below 10%. That alone tells you how rare genuine asset quality is — and why finding it gives you an edge.
Three DSE Banks, Three NPL Stories
Eastern Bank (EBL): ~2% NPL. Six-time winner of Euromoney’s Best Bank in Bangladesh award. AAA credit rating from CRAB with a stable outlook. EBL runs a corporate-heavy portfolio — 78% corporate loans — yet keeps its NPL ratio among the lowest in the sector through rigorous credit standards. When a bank maintains a high ROE and a low NPL simultaneously, it signals sustainable profitability, not a risk-fuelled illusion.
BRAC Bank: ~3–4% NPL. Record profit of Tk 1,432 crore in 2024, a 73% year-on-year jump. Top-10 in Bangladesh Bank’s sustainability rating. BRAC Bank’s strength is disciplined growth — its SME and retail focus attracts quality-conscious depositors while its governance framework (gold award, ICSB National Award for Corporate Governance Excellence 2024) keeps lending standards tight. The NPL ratio confirms what the headline profit number alone cannot: this growth is clean.
Islami Bank (IBBL): ~35–40% NPL. The cautionary tale. Before the S Alam Group took ownership in 2017, IBBL’s NPL ratio sat below 3%. Post-takeover lending irregularities — documented in detail here — pushed non-performing loans past Tk 1 lakh crore by September 2025, with a Tk 70,000 crore provision shortfall exposed by KPMG and Ernst & Young audits. A bank reporting profit while carrying that level of bad debt is not profitable. It is deferring recognition of losses that will eventually arrive.
Why NPL Tells You More Than ROE
Two banks can report 15% ROE. One has a 3% NPL ratio, the other 25%. The first is generating returns from a healthy loan book. The second is generating returns from loans that may never be repaid — and when provisions catch up, that ROE collapses. On the DSE, where the industry default loan rate hit 34% in 2025, this is not a theoretical risk. It is the central risk.
Before buying any DSE banking stock, check the NPL ratio first. Not the dividend. Not the P/E. Not the headline profit. The NPL ratio tells you whether those other numbers are real — or whether they are sitting on a foundation of loans that borrowers stopped paying back months ago.
Bangladesh Bank has set a target to reduce the industry NPL ratio from 36% to 25% by March 2026. Whether that happens, the banks already running clean books — EBL, BRAC Bank, and the handful of others below 5% — do not need the regulator to fix their balance sheets. That independence is worth paying for.
