Agricultural Price Indices 2025: How to Update Your Rural Lease Rent

Key data

If you are the owner or tenant of a rural property with an agricultural lease contract, the publication of these indices triggers your obligation or right to review the rent. The Resolución de 18 de marzo de 2026 de la Subsecretaría publishes the price indices received by farmers and livestock farmers during 2025, the data that the Ley de Arrendamientos Rústicos requires to accurately calculate the new rent amount in contracts that include a review clause linked to these official indices.

This is not a regulation that affects all agricultural contracts: only those that expressly include such a review clause. But if your contract includes it, these indices are mandatory and cannot be disregarded.

What does this regulation establish?

The Subsecretaría annually publishes the price indices received by farmers and livestock farmers, a statistical figure with direct legal value. Its purpose is to serve as a legal reference so that the parties to a rural lease contract can update the rent in an objective and verifiable manner.

The mechanism works as follows:

• The rural lease contract includes a rent review clause linked to these official indices.
• Each year, the Subsecretaría publishes the indices for the previous year.
• The parties apply the published index to calculate the new rent amount.
• The update applies to leased agricultural and livestock operations throughout the national territory.

The legal basis is the Ley de Arrendamientos Rústicos, which establishes this review mechanism to ensure that rent evolves proportionally to the economic reality of the agricultural sector, without depending on subjective negotiations between the parties.

The resolution published on 28 March 2026 takes effect from 18 March 2026, the date it was signed by the Subsecretaría.

Economic and operational impact

The direct impact of this resolution is economic: it determines how much the tenant will pay and how much the owner will receive during the corresponding year. The magnitude of the change depends on the evolution of prices received by the agricultural sector during 2025.

From an operational standpoint, the publication of these indices creates two immediate obligations:

• For the owner: calculate the new rent amount by applying the published index and communicate it to the tenant within the timeframes and in the manner set out in the contract.
• For the tenant: verify that the calculation applied by the owner is correct and corresponds to the official indices published in the BOE.

An error in the calculation or failure to apply the update may lead to civil claims between the parties. If the owner does not apply the update, they may lose income to which they are entitled. If the tenant overpays due to an incorrect calculation, they have the right to claim the difference.

It is important to note that these indices are only binding for contracts that expressly reference them. Contracts that do not include this clause are not required to follow this review mechanism.

Who is affected?

• Owners of rural properties who have leased their land under contracts that include a rent review clause linked to agricultural price indices.
• Tenants of agricultural operations (crops, irrigated land, dry land, horticulture, fruit growing, etc.) with rural lease contracts.
• Tenants of livestock operations who lease rural properties for livestock activity under the Ley de Arrendamientos Rústicos.
• Legal advisors and agricultural managers who manage rural lease contracts for their clients.
• Agricultural cooperatives and companies that lease land for their productive activity.
• Investment funds and family estates with rural properties leased throughout the national territory.

Practical example

Suppose an owner has leased an agricultural property in Castilla y León. The contract, signed in accordance with the Ley de Arrendamientos Rústicos, includes a clause stating that the annual rent will be updated each year by applying the price indices received by farmers published by the Subsecretaría.

The current rent is €6,000 per year. With the publication of the 2025 indices in the BOE (reference BOE-A-2026-7167), the owner can now calculate the new amount by applying the official index to the current rent. The result will be the rent that the tenant must pay during the corresponding year.

Without these published indices, the calculation cannot be carried out in a legally valid manner. This is why the publication of this resolution is the mandatory starting point for any rent review in contracts of this type.

If the contract does not include a review clause, the rent is not modified through this mechanism and the parties must abide by what was agreed in the contract or by what the Ley de Arrendamientos Rústicos establishes for their specific situation.

What should businesses do now?

1. Review all current rural lease contracts to identify whether they include a rent review clause linked to the price indices received by farmers and livestock farmers.
2. Access the official resolution published in the BOE (BOE-A-2026-7167) to obtain the price indices received during 2025 and apply them to calculate the new rent.
3. Calculate the new rent amount by applying the official index to the current rent, following the procedure established in the contract.
4. Communicate the update to the other party within the timeframes and in the manner set out in the contract, keeping documentary evidence of the calculation performed and the indices applied.
5. Verify the calculation if you are a tenant: check that the amount communicated by the owner corresponds to the official indices published. If there is a discrepancy, request justification of the calculation.
6. Consult a legal or agricultural advisor if there are any doubts about the application of the review clause, especially in contracts with ambiguous wording or in situations of disagreement between the parties.
