TOKİ, Turkey's mass housing administration, is how hundreds of thousands of modest-income families have become homeowners: state-built apartments sold with small down payments and long instalment plans, allocated by draw among eligible applicants. For observant families, one feature of these plans demands examination: TOKİ instalments are typically not fixed in lira but adjusted periodically, historically in step with indices like civil servant salary increases. Whether an instalment that grows by index is riba or a legitimate inflation adjustment is one of the liveliest questions in contemporary Turkish fiqh, and honest treatment requires showing both sides.

How TOKİ plans actually work
TOKİ sells below-market housing to eligible buyers, typically first-time owners within income limits, with a modest down payment and instalments stretching over many years. The unpaid balance and the instalments are adjusted periodically according to the index specified in the project's terms, commonly tracking public-sector salary increases, so payments rise over time in nominal lira while remaining anchored to incomes. There is no stated interest rate; there is indexation of a debt. That design is precisely what makes the fiqh question interesting: classical riba is a stipulated excess on a debt, and the question is whether adjusting a debt for the currency's lost value constitutes such an excess or merely preserves the original value owed.
The case that indexation is not riba
A substantial body of contemporary scholarship, well represented in Turkey, holds that in economies with chronic inflation, repaying the real value rather than the nominal figure is closer to justice: money is a measure of value, and returning devalued lira repays less than was owed in substance. On this view, indexing a long-term obligation to an inflation-linked measure is not profit on a loan but protection of the seller's price, especially in a credit sale, where fiqh already permits a deferred price to exceed the cash price. TOKİ's structure can also be analysed as a sale with a price adjusted by an agreed objective index, known to both parties at contract, which several scholars accept as a valid pricing term rather than riba, particularly given the scheme's social character: below-market housing for families the credit market excludes.
The case against, and the cautious middle
The stricter position, held by classical-minded scholars including major fiqh academies in their general resolutions on indexation, is that a debt is owed in the currency and amount contracted, and any built-in increase, whatever its justification, is a stipulated excess: riba by definition, with inflation risk lying where the contract placed it. On this reading, an indexed instalment plan is a variable-rate credit sale whose variability tracks inflation instead of interest rates, an economic cousin of the thing prohibited. The cautious middle, where many Turkish scholars practically land, distinguishes cases: an index agreed upfront, tied to an objective public measure, in a credit sale of a real asset, at below-market social pricing, sits far from the exploitative lending the prohibition targets, and necessity and public benefit (maslaha) weigh heavily for families whose alternative is rent forever or an interest-bearing mortgage. For a family choosing between TOKİ and a conventional bank loan, essentially every scholar would rank TOKİ as the lesser issue by a wide margin.
Practical guidance for an applicant
Read your specific project's payment terms, since indexation rules vary between projects and campaigns, and model the instalments under realistic inflation before committing; the plans are designed to track incomes, but private-sector incomes do not always track the index. If the indexation troubles your conscience, the alternatives are the ones this site maps: participation bank financing at a fixed profit rate, the tasarruf finansman savings system, and state-supported saving through konut hesabı. Where TOKİ is the only realistic path to ownership for your income, the scholarly weight behind indexation-as-value-preservation, the sale structure, and the social pricing give you substantial ground to proceed with a clear conscience, ideally confirmed with a scholar you trust. What no position requires is paralysis: this is a debate among qualified people about a scheme built to house the modest, not a trap.
Frequently asked questions
Does TOKİ charge interest?
No stated interest rate is charged. Instalments and balances are adjusted periodically by an index defined in the project terms, historically tied to public salary increases. The fiqh question is whether that indexation constitutes riba or legitimate value preservation, on which qualified scholars differ.
What do Turkish religious authorities say about indexation?
Contemporary Turkish scholarship includes strong voices accepting inflation indexation of long-term obligations as justice between the parties, alongside stricter views following the classical rule that debts are repaid in nominal terms. The Diyanet's guidance has generally recognised inflation's relevance to long-term debts. Ask your scholar about your specific contract's index.
Is buying a TOKİ home better than a bank mortgage, religiously?
By essentially unanimous reckoning, yes: a conventional mortgage stipulates interest outright, while TOKİ involves a contested indexation question within a real-asset sale at social pricing. Participation bank financing and the savings-finance system are the other alternatives to weigh, each with its own cost and timing profile.
Can I pay a TOKİ balance off early, and does that help?
Early payment options and campaign discounts for settling balances have featured in TOKİ practice, and clearing the balance ends the indexation question along with the debt. If the indexation concerns you, prioritising early settlement is both a fiqh comfort and usually good finance. Check your project's current terms.

Does the TOKİ allocation draw involve gambling?
No. The kura sequences eligible applicants for identical entitlements; no one stakes money on chance for unequal gain. Drawing lots to order equal rights is an accepted method in fiqh, the same analysis as other allocation draws we cover across savings and housing systems.
