Start with the number that matters: one. Turkey has one national sharia screening standard, set by the TKBB Advisory Board, and every katilim fund, both katilim ETFs, every katilim pension fund and the country's only participation brokerage all screen to it. No other market we cover has this. In the US or UK, every fund manager picks its own methodology and investors argue about which one counts. In Turkey the argument is settled: a stock either passes the 33/33/5 screen or it does not, and quarterly KAFIF disclosures on KAP decide which.
That single standard sits on top of genuinely deep infrastructure. As of our August 7, 2026 review, a Turkish halal investor can choose between roughly 78 funds at KT Portfoy alone, a boutique shelf at Albaraka Portfoy, the cheapest index exposure in the market from Ziraat Portfoy, direct sukuk through bank investment accounts, exchange-traded gold from the State Mint, and a brokerage that physically cannot execute a haram buy order.

The three rails
Turkish halal investing runs on three rails, and understanding which rail a product sits on tells you most of what you need to know about how to buy it.
- TEFAS funds. Takasbank's fund platform lets you buy almost any katilim mutual fund (KLU, KTV, KZL, RBV, PPG, ZPK and the rest) from any bank or brokerage app in Turkey. You do not need a participation bank account to be a participation fund investor.
- Borsa Istanbul instruments. The Z30KP Katilim 30 ETF, the ZGOLD gold ETF and the Darphane ALTIN.S1 gold certificate trade like shares through any brokerage account, with intraday pricing.
- Direct sukuk. Treasury kira sertifikalari and participation corporate sukuk can be held directly through bank investment accounts, notably at Kuveyt Turk, with free custody and semiannual rent payments.
Who actually manages the money
Three managers hold the center of the participation fund market. KT Portfoy, a 100% Kuveyt Turk subsidiary licensed in 2015, reported over 607 billion TL under management at its tenth anniversary and invented most of the retail katilim fund categories Turkey now takes for granted: the first money market katilim fund, the first gold fund you can buy with gram gold, the first foreign equity katilim funds. Albaraka Portfoy is the governance boutique, with a three-scholar committee chaired by AAOIFI Board of Trustees member Yousef Hassan Khalawi and a 7.27 billion TL flagship short-term sukuk fund. Ziraat Portfoy is the conventional giant with a katilim line: 2.29 trillion TL in total assets, 17.64% of a 76-firm sector, and the publisher of the market's cheapest halal beta, the Z30KP ETF at a published 0.50% fee.
Note what that last sentence did: it said published. This is the Turkish market's honest embarrassment, and our house obsession. Most katilim funds do not print their management fee on the fund page. You get returns, risk bands and icazet certificates, but the fee lives in a KAP prospectus you have to go find. Across the whole retail katilim shelf we verified exactly three published fee figures: KZL at 0.30%, Z30KP at 0.50%, and Garanti BBVA's OKS katilim funds at 0.85%. We wrote up the whole story in our katilim fund fees investigation.
What performed, and why you should be suspicious
2025 was a spectacular year on paper. Katilim Emeklilik's KJM precious metals pension fund returned 139%, first among all 394 pension funds traded on BEFAS. Silver funds and gold funds crowded the top of the TEFAS tables. Short-term sukuk funds like KTV printed trailing returns around 42.9%, and the KLU money market fund about 44.2%, at our August 2026 crawl.
Every one of those numbers needs deflating. The metals results were a lira gold and silver price surge, a commodity cycle amplified by TL depreciation, not manager brilliance; we unpack that in what the 139% actually means. And the 40-something percent sukuk fund returns are nominal TL returns in an economy where inflation determines whether any of it was real. A katilim fund that returns 44% in a year of comparable inflation preserved your wealth; it did not grow it. Read our real returns piece before celebrating any Turkish fund table.
The instruments nobody else has
Two products deserve special mention because they exist nowhere else in our coverage. The first is the Darphane Altin Sertifikasi (ALTIN.S1): each unit is 0.01 gram of 995 fine gold held by the State Mint, it charges no management fee at all, and Borsa Istanbul links an explicit TKBB Advisory Board ruling approving its purchase by katilim funds. A listed instrument with its own sector-level fatwa is a rarity anywhere on earth.
The second is Kuveyt Turk Yatirim, Turkey's first participation brokerage, licensed July 2024. Its TradePlus platform enforces compliance at the order level: buy orders execute only for the roughly 240 shares passing the Katilim screen, while sells are unrestricted so you can unwind legacy holdings. Account opening, custody and maintenance are free. The screening burden moves from your conscience to the order router.
The honest gaps
- Fee opacity is systemic. Three published fees in the entire retail category is a poor scorecard, and it is the single best argument for reading KAP prospectuses before buying.
- No standalone participation leasing or factoring company exists. Equipment finance runs through participation banks, with Katilim Finans Kefalet guarantees attached where collateral is short.
- Treasury retail windows have gone quiet. The May 2026 gold lease certificate issuance accepted only institutional 1 kg LBMA bars; retail savers have to watch for announced windows.
- Crowdfunding platforms carry no sharia screening. The SPK share-based structure is riba-free by regulation, but neither fonbulucu nor Fonangels vets campaign companies religiously. Your own screening does that work.
Where to start
If you want one practical path: open any brokerage or bank app, buy Z30KP for screened equity beta and a money market katilim fund like KLU for cash, add a gold sleeve through ALTIN.S1 or KZL, and you have a functioning halal portfolio for a published cost of well under 1% a year on most of it. We walk through exactly this in building a halal portfolio from one TEFAS account. For provider scores across the market, see our Halal Money Index.
Frequently asked questions
Do I need a participation bank account to invest halal in Turkey?
No. TEFAS makes every retail katilim fund buyable from any bank or brokerage in Turkey, and Borsa Istanbul instruments like Z30KP and ALTIN.S1 work in any brokerage account. Where you bank and whose funds you own are separate decisions.

Are katilim funds actually screened, or is it marketing?
They are screened by rule, not by promise. Fund prospectuses restrict portfolios to committee-approved lease certificates, participation accounts, TKBB-screened equities and metals, and Borsa Istanbul enforces index membership through quarterly KAFIF compliance disclosures. The screening is the most institutionalized in any market we cover; the weak spots are fee disclosure and, at some issuers, unnamed committee scholars.
