Why a company's cash affects whether its stock is halal

Investors usually like a company sitting on lots of cash: it can pay off debt, survive a crisis, buy back shares. In halal screening, though, cash is tested by its own ratio — and sometimes that ratio alone pushes a good company off the list. Here's why, and how we calculate it.

What's the problem with cash?

A company's spare money doesn't sit idle. It's in bank deposits, government bonds (treasuries), corporate bonds — in other words, it earns interest. That's riba.

AAOIFI Standard No. 21 measures this with the second financial ratio: interest-bearing assets ÷ market capitalisation. The standard requires it to be under 30%. The question is simple:

Through this share, are you becoming a partner in a real business — or in a pile of cash earning interest?

If a large part of a company's value is interest-bearing cash and securities, buying its stock starts to look a lot like putting money in an interest-bearing deposit. An overview of all three ratios: the AAOIFI standard in plain language.

This ratio is different from the interest income ratio. The income ratio measures how much interest the money earned, and purification is based on it. The liquid ratio measures how much money there is — the shape of the balance sheet. One can pass while the other fails.

What we count

The calculation uses the company's most recent quarterly report:

• Cash and cash equivalents — bank accounts, short-term deposits.
• Short-term investments — interest-bearing securities up to one year.
• Long-term interest-bearing securities — bonds longer than a year too. Many screeners skip these; we add them (why — below).

The total is divided by market capitalisation — not at today's price, but by a multi-year average capitalisation. That way a one-day jump or drop in the share price doesn't flip the verdict through noise. For foreign companies the balance sheet is converted from the reporting currency into dollars; otherwise the ratio would be meaningless.

The exact formula and limit: methodology. Every stock page shows the formula with the real figures — "cash + interest-bearing securities ÷ average cap" — so you can recompute the result yourself. The list: halal stocks.

Where we are stricter

1. Long-term bonds are riba too

In accounting, a security maturing within a year goes on the "short-term" line and a longer one on a separate "long-term investments" line. The usual "cash + short-term investments" field only captures the first.

But a three-year bond pays interest just like a one-year one. The "12 months" line is an accounting convention, not a Shariah rule: riba in month 13 is still riba. So we add long-term interest-bearing securities to the ratio as well. As a result, a company that parks its money in long bonds may pass other screeners and fail ours.

2. All cash is treated as interest-bearing

Ideally only the interest-earning part would count. But companies don't split their cash into "interest-bearing" and "non-interest-bearing" in their filings. We can't split it either.

So we count all of it — including the ordinary operating cash a company uses for payroll and suppliers. That deliberately makes us stricter than necessary. The choice is simple: when uncertainty forces us to lean one way, we lean towards "not halal", not towards "halal".

3. No data — no "halal"

If the filing has no cash figure, the ratio isn't computed and the stock stays "undetermined". It is never assumed halal. Same if the filing is stale — the verdict is "undetermined", and the stock is re-assessed as soon as a new report comes out.

One more case: a company with no revenue yet (say, an early-stage biotech) — zero sales, and its only income is interest on cash in the bank. The interest income ratio can't be computed (division by zero), but we don't silently wave it through either — we mark it "doubtful".

What we don't count — and why

Being strict doesn't mean blindly adding everything. A wrongly added number unfairly rejects a halal company — that's an error too.

• Equity stakes in joint ventures don't count. They earn business profit, not interest. The catch is that some filing fields lump bonds and joint-venture stakes into one line. That was the case at aluminium producer Alcoa, for example. So we take only the field that holds debt securities — not the mixed one. Testing showed the mixed field would have unfairly rejected two halal companies. See Alcoa's current status on its page.
• A stale long-term figure isn't added. Dividing a very old balance-sheet number (older than the report-age limit in the methodology) by today's capitalisation gives a fake ratio. In that case the long-term part is left out of the ratio — a limitation we openly acknowledge.

The cash ratio can't catch everything

SPACs — "blank-cheque" shell companies — hold investors' money in a special trust account and earn interest on it. Logically that's a pure "pile of cash". But the trust money doesn't land on the usual "cash and short-term investments" line — our data source shows almost zero there. In other words, the liquid ratio doesn't catch SPACs.

So we stop them another way: in step one, the activity screen, the "shell companies" industry is on the blocked list. Where one ratio falls short, a second layer works. Blocked activities: the list.

Why the status changes

Cash is one of the fastest-moving numbers on a balance sheet. If a company raises money by issuing bonds, sells a large asset, or its share price falls for a long time (lowering the average cap), the liquid ratio rises — and a stock that was halal yesterday can leave the list tomorrow. The reverse happens too. More: why halal status changes.

Bottom line

• Cash affects halal status because it almost always earns interest.
• We count long-term bonds and all cash — stricter than AAOIFI's minimum.
• Things that earn no interest, such as joint-venture stakes, we deliberately leave out.
• When data is missing — not "halal", but "undetermined".

This approach sometimes leaves out a company that may in fact be halal. We say so openly: our result is independent analysis, not a fatwa.
