How to Underwrite Credit Risk, and Why Sharia Finance Demands You Do

Would you give Google $100m in credit?

Most people answer yes without thinking about it. Google is a safe bet. But why? If you cannot articulate the reasoning, you assumed it felt safe. That is not the same as underwriting the risk.

Credit underwriting converts instinct into structured analysis. It separates informed capital allocation from a gut call. In Islamic finance, it is not optional. The obligation to understand what you are doing with your capital before you commit it is embedded in Shariah methodology.

What Credit Underwriting Actually Is

Underwriting credit means assessing the probability that a borrower will repay, and deciding what terms, if any, are appropriate given that probability.

It applies a framework across four categories of information:

1. Business fundamentals What does the company do? How does it make money? Is the business model sustainable? A company that makes money only under specific conditions (a commodity boom, a temporary regulatory gap, an expiring subsidy) is a different credit risk than one with durable economics.

For a mobile network operator: it owns licensed spectrum, fixed infrastructure such as masts and fibre backbone, and a subscriber base with contracted monthly billing. Revenue is largely recurring and driven by usage rather than a single customer relationship. Churn is slow, and the regulator provides a degree of operational continuity even through financial distress. Those are positive credit characteristics for an obligor.

2. Financial position Does the company earn more than it spends? How much debt does it already carry? Are assets greater than liabilities? Is cash flow consistent or lumpy?

Key ratios to examine:

• Debt-to-EBITDA: how many years of earnings would it take to repay total debt? Under 3× is generally manageable. Above 5× raises questions.
• Profit coverage: does operating profit cover fixed obligations comfortably? Thin margins against large fixed costs are a warning sign in capital-intensive businesses.
• Current ratio: can near-term assets cover near-term liabilities?

You do not need audited accounts to run a directional analysis. Industry averages, regulatory filings, and news flow can triangulate a reasonable view even when full financials are not public.

3. Structural protections What recourse exists if the obligor does not pay? In SukukFi's invoice finance structure, the key protection is the assignment of receivables under English law. Suppliers who sell to the obligor (the telecom carrier) assign their outstanding invoices to SukukFi. The obligor receives a formal assignment notice and is directed to pay those invoices to a specific IBAN controlled by Fuze Finance on SukukFi's behalf. The assignment gives SukukFi a direct legal claim against the obligor's specific payment obligations. The obligor is contractually required to pay those invoices to the Fuze Finance IBAN once the assignment notice is served, independent of the supplier's own financial condition.

Verification is the second layer. CommTrade confirms that traffic has been delivered before capital is advanced. Capital does not move against a claimed invoice. It moves against a verified obligation. This reduces the risk of advancing against disputed or fraudulent invoices.

The practical question is: even with a valid legal assignment, can the obligor pay? That is why the credit assessment focuses on the obligor, not the supplier. The supplier's role ends once the assignment is in place. The obligor's willingness and ability to pay is what determines the outcome.

4. Track record and market position A company that has serviced its obligations through previous cycles, including interest rate rises, economic downturns, and competitive pressure, has demonstrated something a new entrant cannot. Market position matters: a carrier with 30% mobile market share and owned infrastructure is a different credit to a pure MVNO with no fixed assets and one distribution contract.

The Google Example

You would extend credit to Google because:

• The business model is diversified and dominant in its category (search advertising, cloud, YouTube)
• Revenue is large and recurring at scale
• The balance sheet holds more cash than debt
• The track record spans two decades of growth through multiple cycles
• Market position is durable: switching costs for search are high, cloud infrastructure has long contract cycles

You are not extending credit based on a feeling. You are extending it based on a structured view of those four categories, weighted against the size and tenor of the exposure.

For a smaller, regional company, the same framework applies. The absolute numbers are smaller. The market position is local. The track record is shorter. The structural protections become more important to compensate for lower inherent quality.

Why Sharia Finance Requires This

The connection to Islamic finance is not incidental. Shariah-compliant structures require that providers of capital participate in the risk and return of a transaction. You cannot, under Sharia, guarantee a return and call it profit. The prohibition on riba exists because guaranteed returns sever the provider of capital from the economic reality of the underlying activity.

The Sharia investor cannot hand over money and rely on a guarantee. They must understand what they are financing and accept the economic outcome. That acceptance requires knowledge. Ignorance of the risk you are taking is not permitted when you are a genuine party to a transaction.

In classical Islamic scholarship, this connects to ghunm bil ghurm, the principle that gain must accompany liability. If you want a share of the profit, you must carry a share of the risk. You cannot carry a risk you have not assessed.

Due diligence, in Islamic finance, is not a compliance exercise. It is a prerequisite for a valid transaction.

A Practical Framework for Retail Investors

Most retail investors are not credit analysts. That does not make due diligence impossible. It means applying a simplified version of the same framework:

Step 1: Understand the company's role. What does it do? Is it a business you can follow intuitively? Can you explain in one sentence how it makes money?

Step 2: Check its market position. Is it an incumbent with assets, or a newer entrant? Does it have regulated infrastructure (spectrum, cables, towers) that represents genuine fixed assets and barriers to entry?

Step 3: Look for red flags. Recent restructurings, missed payments to other creditors, regulatory sanctions, or unexplained management changes are all worth investigating. Public filings, news searches, and regulatory announcements cover most of this.

Step 4: Assess the structure. Is your exposure to the company's general creditworthiness, or to a specific invoice from a specific debtor? The latter is lower risk because it is self-liquidating: the invoice either gets paid or it does not, independent of the company's overall financial condition.

Step 5: Set a limit you are comfortable with. Credit limits are about how much you can afford to lose if you are wrong, scaled to the probability of being wrong. Even Google-quality credit gets a limit. The limit is just higher.

What This Means for duPRT Depositors

SukukFi's duPRT vault deploys capital into telecom invoice receivables. Suppliers sell services to a telecom obligor and assign their outstanding invoices to SukukFi. The credit exposure is to that obligor's willingness and ability to pay its suppliers' invoices.

The due diligence question is: what is the probability that the obligor does not pay? That question is answerable. The obligor's market position, fixed assets, subscriber base, regulatory standing, and payment history are all investigable. Not with the precision of a bank's credit desk, but well enough to form a directional view.

SukukFi publishes credit assessments for each obligor in the vault. The first covers PrimeTel, the current primary obligor, and is available here. The methodology used in that assessment is this framework, applied to publicly available information.

Underwriting credit is a skill, not a credential. The framework is learnable. For investors in Islamic private credit, learning it is part of the obligation.
