Is Block (SQ) Halal? Full Faith-Screening Breakdown

Ask "is Block halal" and you get a shrug from most screening apps, because Block is the awkward middle case. Call it a bank and you are wrong, call it a software company and you are also wrong. It moves money for millions of merchants and consumers, holds their balances, lends against their future sales, sells them bitcoin, and pays for all of it partly with convertible notes. Every one of those pieces lands somewhere different on a Shariah screen, and the ratios that decide the verdict move with the stock price.

One housekeeping note before the math. Block changed its ticker from SQ to XYZ in 2025, so filings and quote pages now show XYZ. Most screening tools, watchlists and older fatwa discussions still say SQ, and this article uses both.

What Block Actually Does

Block runs two ecosystems and a handful of side bets.

Square is the merchant side: card readers and terminals, point-of-sale software, payroll, and Square Loans, which advances working capital to sellers and gets repaid as a fixed percentage of their daily card sales. Square Financial Services, Block's Utah industrial bank, originates a growing share of that credit directly rather than through a partner bank.

Cash App is the consumer side and now the bigger of the two. On trailing twelve months through March 2026, Block reported about $24.5 billion of revenue, with roughly $15.4 billion from Cash App and $8.7 billion from Square. Cash App carries peer-to-peer transfers, the Cash App Card and its interchange, direct deposit, stock and bitcoin trading, Afterpay's buy-now-pay-later product, and Cash App Borrow, a small short-term loan repaid with a flat fee.

Then there is bitcoin. Block sells bitcoin to Cash App customers and books the gross proceeds as revenue, which is why a company with $24.5 billion of revenue generated only about $11.0 billion of gross profit. Block also holds bitcoin in its own treasury, builds the Bitkey self-custody wallet, and through Proto sells mining hardware and chips.

The parts a Shariah screen actually flags

Strip out the neutral plumbing and three things stand out. Cash App Borrow charges a flat fee on a cash advance. Afterpay charges no interest but does charge late fees in most markets. Square Loans charges a fixed dollar fee on an advance repaid from sales. All three are structured to avoid the word interest, and none of them survive contact with the classical definition. A qard is meant to be gratuitous, and any stipulated excess over the principal is riba al-nasiah whether you call it a fee, a factor rate or a subscription. Quran 2:275 to 279 draws the line at the principal itself, and AAOIFI's standards on murabaha and qard follow that reading. So Block earns real non-permissible income. The question is how much, relative to what.

The Financial-Ratio Screen

Using the most recent balance sheet, with the stock near $81 and about 601 million shares outstanding, market capitalization sits around $48.8 billion. Total debt is roughly $7.8 billion, of which about $6.0 billion is long term. Cash and equivalents are roughly $6.9 billion, and total assets about $40.0 billion.

Debt screen. Interest-bearing debt to market cap comes to roughly 16%. Comfortably inside the 30% line used by AAOIFI Standard 21 and by Dow Jones Islamic Market, and inside the 33% line used by S&P Shariah and MSCI. On a total-assets denominator, which is what FTSE Shariah and AAOIFI's asset-based variant use, it is about 20% against a 33% cap. Passes there too.

A detail worth knowing: a large slice of Block's debt is convertible senior notes issued at coupons of 0% to 0.25%. People assume zero-coupon paper is harmless. Screens do not read it that way. AAOIFI and the major index committees classify conventional debt instruments by their legal form, and a conventional bond with a zero coupon is still an interest-bearing liability with an embedded conversion right. It counts in full.

Cash and interest-bearing securities screen. Corporate cash and equivalents alone are about 14% of market cap and 17% of total assets. Add Block's marketable securities and the interest earned on customer funds and it climbs, but on the current numbers it stays under the 30% cap.

The screen most likely to trip Block. FTSE Shariah and several AAOIFI-aligned providers add a receivables test, capping cash plus receivables at 50% of total assets. Block carries settlements receivable, customer funds, loans held for sale from Square Loans and Afterpay, and consumer receivables, and those balances are large relative to $40 billion of total assets. This is the ratio to watch, and it is the one most likely to produce a different answer from different providers on the same day.

The 5% income screen. Here is where the denominator does the heavy lifting. Interest income, lending fees and late fees measured against $24.5 billion of revenue look tiny, because that revenue number is inflated by the gross bitcoin proceeds Block passes almost entirely back out. Measured against $11.0 billion of gross profit, which is how Block itself talks about its business, lending and interest-related contribution is plausibly in the high single digits. AAOIFI screens on total income, DJIM screens on revenue, and Block is exactly the kind of company where that choice flips the result. If your screener uses gross profit or a revenue figure adjusted for bitcoin pass-through, Block sits near or above the 5% line rather than safely below it.

The Verdict Under Each Framework

Islamic (AAOIFI, DJIM, S&P Shariah)

Not a clean pass and not a clean fail. On the leverage and liquidity ratios Block passes every major methodology with room to spare. The business-activity screen is where scholars diverge. One camp treats Block as a payments and software company whose credit products are incidental, which puts it in the compliant-with-purification bucket. The other camp reads Square Financial Services, Cash App Borrow and Afterpay as a genuine consumer and merchant lending operation embedded inside the product, which makes lending a core activity rather than a side effect, and core impermissible activity is not curable by purification at any percentage.

Practically, expect DJIM and S&P style screens using unadjusted revenue to lean pass-with-purification, and expect AAOIFI-strict and FTSE-style screens using total assets and receivables caps to be far more likely to exclude. The framework comparison page walks through why the same company gets different answers.

Christian BRI

Inspire's BRI methodology screens six categories: abortion, alcohol, gambling, pornography, tobacco, and human rights violations. Block has no direct exposure to any of them, so the exclusion list itself is clean. The friction is elsewhere. Cash App functions as a funding rail for online sportsbooks, which is facilitation rather than participation, and BRI screens generally do not exclude on facilitation. The stewardship concern that does register is conduct: Block absorbed significant US regulatory action in 2025 over Cash App's handling of fraud disputes and over anti-money-laundering program gaps. On a values-alignment reading that weighs treatment of customers, that is a real mark against it even though it triggers no categorical exclusion.

Catholic USCCB

The USCCB Socially Responsible Investment Guidelines exclude abortion, contraception, embryonic stem cell research, certain weapons and pornography, and Block touches none of them. Where the guidelines bite is the economic justice section, which addresses access to banking and predatory lending. Cash App Borrow's flat fee, annualized over its short repayment window, produces an effective rate that a USCCB-aligned reviewer would reasonably question, and Afterpay late fees fall in the same category. The likely outcome is a pass with an engagement flag rather than an exclusion, since USCCB investors are directed toward shareholder engagement on exactly this kind of issue rather than divestment.

Jewish halakhic

Ribbis rules govern lending at interest between Jews, and Block's borrowers are overwhelmingly the general US public. Bais HaVaad's two-tier framing applies here: passive minority ownership of a public company that lends is treated far more leniently than direct participation in the lending itself, and the heter iska mechanism that would be required for an Israeli lender is not the live question for a US issuer with a non-Jewish borrower base. Most poskim following that reasoning would permit a minority equity position in Block. A shareholder holding a controlling stake, or one who wants to avoid any benefit from ribbis income, would need a heter iska structure or would avoid the position.

Latter-day Saint

The LDS lens has no formal exclusion list, so screening leans on counsel about gambling and about speculation, including long-standing church teaching cautioning members away from speculative investing. Block gives that lens two things to chew on. Cash App Investing puts fractional stock and bitcoin trading in front of a young retail user base, and Block holds bitcoin on its own balance sheet, tying corporate results to an asset that moves 50% in a quarter. Neither is prohibited. Both make Block a poor fit for an investor who reads that counsel strictly, and a defensible holding for one who treats the bitcoin exposure as a business line rather than a house bet.

The crypto question underneath all of it

You cannot fully answer whether Block is halal without a position on bitcoin itself, and scholars are genuinely split. Mufti Taqi Usmani and the Darul Uloom Karachi position treats cryptocurrency as lacking the qualities of legitimate mal and rejects it. The Shariah Advisory Council of Malaysia's Securities Commission reached the opposite conclusion, recognizing digital assets as tradable property with customary value. If you follow the prohibitionist view, Block's bitcoin sales, treasury holdings and mining hardware are impermissible activity, not merely a ratio input, and the screen ends there. If you follow the permissive view, the bitcoin lines are neutral commerce and only the lending products matter.

Purification and What Could Flip the Verdict

Block pays no dividend, so the classic dividend-purification calculation does not apply. Under the approach that purifies the non-permissible share of attributable earnings regardless of distribution, you would take your share of net income and set aside the impermissible fraction as charity, given without expectation of reward.

An illustration using current numbers, not a figure from Block's disclosures: trailing net income of roughly $807 million across about 601 million shares is close to $1.34 per share. If you judge 8% of earnings to be interest and lending derived, purification runs near $0.11 per share per year. On an $81 stock that is roughly 0.13% of position value annually, or about $13 on a $10,000 holding. Recompute it yourself each year from the actual filings rather than reusing that number, because the fraction moves.

Three things could flip the verdict, and only one of them is about Block's business.

The first is the stock price. Debt to market cap is the ratio with the most slack right now at about 16%, but the denominator is the share price. Holding $7.8 billion of debt constant, market cap would need to fall under roughly $26 billion to breach the 30% cap, which is a share price in the low $40s. A drawdown of that size has happened to this stock before, and it would convert a comfortable pass into a fail without any change in how Block operates.

The second is the mix. Cash App Borrow and Square Financial Services have been among the faster-growing gross profit lines. If lending gross profit keeps compounding while the payments base grows slowly, the 5% income test tightens on its own, and it tightens first for screeners using gross profit rather than headline revenue.

The third is an issuance or a buyback. New convertible notes push the debt ratio up. Aggressive repurchases shrink both the share count and the market cap, which cuts both ways depending on the price paid.

Seeing Block's Live Verdict

Ratios computed on a March balance sheet and a July share price go stale fast, which is the whole problem with static halal-stock lists. Block's current screen, with the debt and liquidity ratios recalculated against the live market cap, the business-activity flags, the conduct record and the purification estimate, sits on the Block (SQ) screening page. If you want to run the same three-axis check on the rest of your holdings, including any position where a lending product is buried inside a software business, start from the stock screener.

The Bottom Line

Block passes the leverage and liquidity screens with real room, at roughly 16% debt to market cap and about 20% debt to total assets, and it fails none of the categorical exclusion lists used by BRI, USCCB or halakhic screens. The verdict turns entirely on one judgment call: whether Cash App Borrow, Afterpay and Square Loans are incidental fee income or a lending business Block deliberately built, and that judgment depends on whether your screener measures the 5% test against $24.5 billion of bitcoin-inflated revenue or $11.0 billion of gross profit. Get an answer on that denominator question before you get comfortable with a pass, because it is doing more work here than any other number on the page.
