Is TSM Stock Halal? The 2026 Shariah Verdict on TSMC, Micron and SK Hynix

The Short Answer: All Three Pass — Here Is the Math That Proves It

The short answer: yes, conditionally — all three of the big memory-and-foundry names pass the AAOIFI Shariah screen on mid-2026 data, and by margins so wide the verdicts are not close calls. TSMC carries roughly US$34.2 billion of debt against a US$2.30 trillion market cap — about 1.5%, against a 30% limit. Micron carries roughly US$6.4 billion against US$1.17 trillion — about 0.5%. SK Hynix carries roughly ₩21.8 trillion against ₩1,549 trillion — about 1.4%.

That is a very different situation from the broad-market funds we have screened before. XEQT fails and the S&P 500 as an index fails because they hold conventional banks and insurers — a stage-one, business-activity failure that no ratio math can rescue. Semiconductor manufacturers are the opposite case: clean business activity, and balance sheets that the AI-and-memory boom has made almost comically conservative relative to their market caps. The conditions attached to the verdict — purification of interest income, quarterly re-screening, one genuine scholarly gray area — are the substance of this article, along with a tax trap on TSM specifically that most Canadian holders miss.

The Screen We Are Applying: AAOIFI Standard 21

AAOIFI Shari'ah Standard No. 21 is the strict benchmark — no buffer zone. It runs in two stages:

• Stage 1 — business activity: a company fails if more than 5% of revenue comes from conventional finance, alcohol, tobacco, gambling, pork, adult entertainment, or weapons.
• Stage 2 — financial ratios: interest-bearing debt ≤ 30% of market cap; cash plus interest-bearing securities ≤ 30% of market cap; impermissible income ≤ 5% of total income.

Index providers apply looser variants — S&P and FTSE use 33%-ish thresholds with different denominators — so a stock that passes AAOIFI passes everything. All ratios below are computed on each company's most recent quarterly balance sheet divided by its market cap at the July 1–2, 2026 closes. Holdings and prices move; the "re-screen quarterly" instruction at the end is not boilerplate, it is part of the ruling.

TSMC (TSM): Pass, With a Purification Duty on a US$105.8B Cash Pile

Taiwan Semiconductor Manufacturing Company is a pure-play foundry — it manufactures chips designed by others. There is no lending arm, no insurance sideline, no excluded revenue stream of any size. Stage one is a clean pass.

Stage two, on the Q1 2026 balance sheet (March 31, 2026): total debt of roughly TWD 1,016 billion — about US$34.2 billion — against a market cap of US$2.30 trillion at the July 1 close of US$444.23. That is roughly 1.5%, a twentieth of the AAOIFI limit. Cash and short-term investments of roughly TWD 3,384 billion (about US$105.8 billion) come to roughly 4.6% of market cap, also far under 30%.

The condition worth taking seriously is that third pile of money. US$105.8 billion in cash and short-term investments earns interest, and interest is riba regardless of how small a share of TSMC's income it represents. AAOIFI handles this through purification, not exclusion: as long as impermissible income stays at or under 5% of total income, the stock remains compliant and the investor donates the impermissible slice of their return to charity. Independent confirmation that TSMC clears the 5% line: it is the largest holding of SPWO (SP Funds S&P World ex-US ETF, which tracks an S&P Shariah index) at roughly 20.9% and a top holding of SPTE (S&P Global 1200 Shariah Information Technology index) at roughly 11.5% — both funds track S&P Shariah indices screened by an index committee, which drops any name that breaches the thresholds at rebalance.

Micron (MU): The Cleanest Pass of the Three

If you searched "is Micron halal" or "is Micron Shariah-compliant," here is the direct answer: yes, and it is not close. Zoya rates Micron Technology Shariah-compliant as of June 2026, and two Shariah-certified ETFs hold it — HLAL (Wahed FTSE USA Shariah ETF, screened by Yasaar Limited under a fatwa covering the FTSE Shariah USA index series) at 2.99% of the fund, and SPUS at roughly 3.6%. When AAOIFI-aligned, FTSE Shariah, and S&P Shariah methodologies all reach the same verdict independently, the ruling is about as robust as stock screening gets.

The numbers behind it, from the fiscal Q3 2026 balance sheet (May 28, 2026): total debt of roughly US$6.4 billion against a market cap of roughly US$1.17 trillion — about 0.5%. Cash and short-term investments of roughly US$26 billion sit at about 2.2%. The memory-price supercycle did this: Micron's market cap inflated past a trillion dollars while the company paid debt down, leaving ratios that are rounding errors against the 30% thresholds. DRAM, NAND, and HBM manufacturing raise no stage-one issue.

SK Hynix: Passes the Screen — Buying It From Canada Is the Real Problem

SK Hynix passes stage one (memory chips, no excluded revenue) and passes stage two comfortably on Q1 2026 data: roughly ₩21.8 trillion of debt against a ₩1,549 trillion market cap is about 1.4%, and roughly ₩54.4 trillion of cash and short-term investments is about 3.5%. The independent confirmation is again index inclusion — SK Hynix is the third-largest holding of SPWO at roughly 4.75%, inside an S&P Shariah-screened index.

The practical ruling for a Canadian, though, is about access:

• Primary listing: Korea Exchange (KRX: 000660), at ₩2,232,000 per share at the July 2, 2026 Seoul close. The big Canadian discount brokers do not offer retail trading on the KRX.
• OTC ADR: HXSCL trades over-the-counter in the US, but it is unsponsored and thinly traded — the bid-ask spread on an illiquid ADR can quietly cost more than years of ETF fees.
• The realistic route: SPWO at a 0.55% expense ratio, which packages SK Hynix (~4.75%), TSMC (~20.9%), and Samsung (~5.3%) in one Shariah-screened, US-listed fund.

My position: unless you have a broker with Seoul access and a specific thesis, take the ETF. You get the same Shariah-screened exposure, quarterly re-screening done by the index committee, and a published purification figure — three jobs you would otherwise be doing yourself.

The Part Most People Miss: The Denominator Is a Stock Price

Every ratio above divides by market capitalization, and market cap changes every trading day. These three names have been enormous beneficiaries of the AI-and-memory rally — Micron trading above US$1,000 a share is precisely why its debt ratio reads 0.5%. A screen that passes because the stock went up can, in principle, fail because the stock went down.

In practice, the cushion here is vast. With debt unchanged, Micron's market cap would need to fall roughly 98% before debt hit 30%; TSMC's, roughly 95%. The realistic flip risks are elsewhere: a debt-funded fab expansion raising the numerator (TSMC and SK Hynix are both in historic capex cycles), a cash pile compounding faster than the share price, or — subtlest of all — interest income breaching 5% of total income during a cyclical earnings trough, when the denominator of that test collapses. Memory is a brutally cyclical business; the quarter to re-check hardest is the one where earnings disappoint. Zoya and Musaffa both re-rate quarterly, and thirty seconds per ticker is cheap insurance.

One honest gray area no ratio captures: advanced chips are dual-use technology. Direct defence revenue at all three companies is far below the 5% stage-one threshold, which is why every major index methodology passes them. But if your scholar takes a stricter view of military end-use, the apps will not flag it — that exclusion has to be your own.

The Tax Layer: TSM's 21% Withholding Follows You Into the RRSP

Here is the trap specific to TSM that halal screening apps will never mention. Canadians assume US-listed stock plus RRSP equals no dividend withholding. That exemption comes from the Canada-US tax treaty and covers US-source dividends only. TSM is an ADR of a Taiwanese company — its dividends are Taiwan-source, and Taiwan withholds 21% for nonresident investors. That 21% applies in your RRSP and your TFSA, where no foreign tax credit is available. Micron, a US company, follows the familiar rules: 0% withholding in an RRSP or RRIF, 15% unrecoverable in a TFSA, 15% creditable in a non-registered account.

Two placement consequences. First, if you hold TSM, a non-registered account is the only place you can claim any credit for the Taiwanese withholding — though TSMC's modest yield keeps the absolute dollars small. Second, US-listed holdings (TSM, MU, SPWO, HLAL, SPUS) in a non-registered account count toward Form T1135, required when the total cost of your specified foreign property exceeds $100,000 CAD — property inside an RRSP or TFSA is exempt from the form. If you are building these positions inside a TFSA, our halal TFSA guide walks the account mechanics.

Stock-Picker or ETF Route? The Honest Comparison

Owning TSMC, Micron, or SK Hynix directly is halal on current data. Whether it is wise is a separate question — three cyclical companies in one industry is concentration risk that no screening standard measures. The alternatives:

• Own the sector through Shariah ETFs: SPUS (0.45%) and HLAL (0.50%) both carry heavy semiconductor weights already — Micron included — and SPWO (0.55%) adds TSMC and SK Hynix. Our ranked list of the best halal ETFs for Canadians compares all of them on fees and screening.
• Fully managed: Wealthsimple's Halal portfolio (built on WSHR, its Shariah World Equity Index ETF at a 0.50% management fee) runs roughly 0.9-1.0% all-in — we scored it in our Wealthsimple Halal review.
• Direct stocks: cheapest to hold (no MER), but you own the quarterly re-screening, the purification math, and the withholding-tax placement yourself.

For most readers, a Shariah ETF core with at most one or two conviction positions on top is the structure I would actually run. The screen tells you what is permissible; it does not tell you what is prudent.

The Bottom Line

TSMC, Micron, and SK Hynix all pass the AAOIFI screen on mid-2026 data — clean business activity, debt ratios between 0.5% and 1.5% of market cap, cash ratios between 2.2% and 4.6%, and each name independently held inside at least one Shariah-certified index fund. The verdicts are conditional in the ways that always apply to single stocks: purify the interest slice of your return, re-screen every quarter, and know that a market-cap-based screen is only as current as the last price. And if you hold TSM, budget for the 21% Taiwan withholding your RRSP will not protect you from.
