The 2025/26 Crop Plan outlines R$594.4 billion in total rural credit, with LCAs accounting for R$328 billion, or 55% of the funding. In the 2024/25 cycle, they represented 43% of the total.

Currently, income earned from LCAs is exempt from taxation. However, the Ministry of Finance has proposed a 5% tax on earnings, included in Provisional Presidential Decree 1,303/2025, which still requires Congressional approval. If passed, the new rule would take effect in 2026. Despite the tax, Gilson Bittencourt, deputy secretary for agricultural policy and agro-environmental business at the Ministry of Finance, believes LCAs will remain attractive to investors.

“The Finance Ministry’s proposal to impose a 5% tax maintains LCAs’ advantage over other fixed-income instruments while also helping to fund interest rate subsidies in rural credit,” said Mr. Bittencourt.

He noted that high interest rates, particularly the current Selic level near 15% per year, made it unfeasible to keep loan interest rates unchanged in the new Crop Plan. “We wanted to avoid raising rates, but the numbers had to add up,” Mr. Bittencourt said during a media briefing after the plan’s release earlier this month. “In agriculture, the lower the rate, the better. But worse than a slightly higher rate is having no funds at all. That was the government’s main concern.”

Mr. Bittencourt also acknowledged that a drop in the Selic rate could reduce demand for LCAs, which are currently among the most profitable investment options. Nonetheless, investor familiarity with LCAs may help sustain demand even in a lower-rate environment.

Looking ahead, Mr. Bittencourt said the “ideal scenario” for agricultural policy would be a Selic rate of 8.5%—a projection that was common among economists and the government earlier in 2024. In such a scenario, LCAs could be issued at 90% of the benchmark rate plus a spread of up to 3%, resulting in single-digit loan interest rates for market-based credit lines. This would also increase the incentive for banks to use their own funds in rural lending, further easing the fiscal burden of subsidies.

However, Ivan Wedekin, a consultant and former secretary of agricultural policy at the Ministry of Agriculture, warned that taxing LCAs could hurt their competitiveness relative to other instruments, such as bank-issued CDBs, which are already taxed. He also voiced concerns about market confidence.

“Taxing one type of instrument sets a precedent. There’s now a risk that the government could raise the tax from 5% to 10% or even revoke exemptions altogether. That creates uncertainty across the market,” Mr. Wedekin told Valor.
