Here is a category where honesty saves you time: KTV, RBV and ZPK are functionally the same product. All three hold short-maturity TL lease certificates, mostly Treasury paper, plus participation accounts. All three sit one step of risk above a money market fund. All three are TEFAS funds buyable from any bank in Turkey. And none of the three prints its management fee on its fund page; every fee lives in a KAP prospectus. When products converge this completely, the decision comes down to governance taste, scale and the fee homework the industry refuses to do for you.

The three, side by side
| KTV (KT Portfoy) | RBV (Albaraka Portfoy) | ZPK (Ziraat Portfoy) | |
|---|---|---|---|
| Manager type | Participation-native, Kuveyt Turk group | Participation-native boutique | Conventional state giant, katilim line |
| Committee | Five scholars, published with biographies | Three scholars, chaired by an AAOIFI trustee; icazet dates on fund pages | Committee in fund rules, scholars unnamed |
| Scale | The category workhorse; about 42.9% annual return at our crawl | About 7.27 billion TL, Albaraka's retail flagship | State-scale distribution through every Ziraat channel |
| Fee | KAP prospectus only | KAP prospectus only | KAP prospectus only |
| Distinguishing fact | General access unlike KT's qualified-only serbest funds | Strongest scholar credentials in the category | Available everywhere Ziraat reaches, which is everywhere |
What these funds are for, and what they are not
Use this category for money with a months-long horizon: it captures lease certificate carry with limited duration risk, sovereign-heavy books keep credit risk modest, and returns land a notch above money market katilim funds like KLU and PPG. The roughly 42.9% annual return KTV showed at our August 2026 crawl is what that carry looked like in a high-rate year, and it is a nominal TL number: whether any of it survived inflation is a separate question with an uncomfortable answer most years, which we work through in our real returns piece. None of these funds is an inflation hedge, and pairing one with gold or screened equity exposure is portfolio construction, not disloyalty.
Also know what sits inside: the private sector sukuk sleeve in each carries participation-sector corporate credit risk, and Turkish corporate sukuk trade thin, which can widen swings in stress. The sovereign core dominates in all three, which is why we treat them as one risk category.
How to actually choose
- Governance-first: RBV. An AAOIFI Board of Trustees member chairs the committee and the icazet date is printed on the fund page. Nobody else in the category matches that visibility.
- Ecosystem-pragmatist: ZPK if your money already lives at Ziraat; the product is sound and the counter is next door. Participation-first investors will mind the unnamed scholars.
- Depth-and-access: KTV, the sector's workhorse, from the manager with the deepest participation research bench, and general access on TEFAS unlike several of KT Portfoy's larger qualified-only funds.
- Everyone, before buying any of them: open all three KAP prospectuses and compare the fee lines. In a converged category, the cheapest compliant fund wins, and the fee is the one variable the fund pages will not show you.
The fee paragraph we wish we did not have to write
Three credible managers compete in this category, which should be great for investors, but competition only disciplines prices people can see. Prospectus-only disclosure blunts it, and the pattern is market-wide: of the whole retail katilim shelf, only KZL, Z30KP and Garanti's OKS funds print fees. We documented the problem across the market in our katilim fund fee investigation, and we will keep naming it in every category review until printing the fee becomes the norm. Until then: the prospectus is the price tag. Read it.
Frequently asked questions
Are these funds safer than a participation bank deposit?
Different risk, not strictly safer. A participation account carries bank risk with TMSF insurance up to the statutory limit; these funds carry market risk on sovereign-heavy paper with no insurance but also no single-bank exposure. Short-duration sovereign lease certificates are the halal TL benchmark asset, and daily NAV moves are normally small. For emergency money, a money market katilim fund or participation account fits better; this category is for the next layer out.
Why not just buy lease certificates directly and skip the fee?
You can, through a bank investment account, and for hold-to-maturity money it is the zero-fee answer, covered in our direct sukuk guide. The funds earn their fee by handling the issuance calendar, reinvestment and liquidity: you can exit a fund any day, while direct holdings mostly mean waiting for maturity. Calendar convenience versus carrying cost is the whole trade.
What happens to these funds when rates fall?
Short-duration carry funds reprice gradually: returns drift down as maturing paper rolls into lower-rent issues, without the price pop longer-duration funds enjoy. If you hold a view that Turkish profit rates are heading down and you want to monetize it, the full-duration siblings (KTN at KT Portfoy, RBT at Albaraka) are the instruments for that view, with the symmetrical warning that they lose value when rates rise.

How do these differ from the money market katilim funds?
One step of maturity, one step of return, one step of patience. KLU and PPG hold very short paper with same-day or next-day liquidity for emergency and idle cash. KTV, RBV and ZPK extend maturities to capture more carry, which means slightly more NAV movement and a horizon better measured in months. The clean setup uses both layers: the money market fund as your liquid floor, the short-term sukuk fund for the savings layer above it, and neither pretending to be an inflation hedge.
