The national price index IGP-M ended 2025 with a slight deflation of 1.05%, the Fundação Getulio Vargas (FGV) reported, surprising market projections and signalling a shift in price pressures across Brazil’s economy. The move was driven mainly by falls at the wholesale level, while consumer and construction prices continued to rise moderately.
IGP-M deflation Brazil 2025 and what it means for farmers
The Index of Wholesale Prices (IPA), which carries a 60% weight in the IGP-M, fell 0.12% in December and accumulated a 3.35% decline over the year. That contraction reflected lower costs for agricultural and industrial inputs as harvests improved and international commodity prices eased. For farmers, the immediate effect has been a reduction in expenses for fertilisers, pesticides and seeds, improving margins in a year when crop prices were under pressure.
However, the picture is mixed. Retail inflation, measured by the Consumer Price Index (IPC) and weighted at 30% of the IGP-M, rose 0.24% in December and ended 2025 up 4.08%. The National Construction Cost Index (INCC) increased 6.10% across the year as materials and labour costs climbed. The divergence between wholesale deflation and higher consumer and construction prices illustrates how cost relief at the production stage does not always translate quickly into lower prices for households.
Producers who benefited from cheaper inputs still face market risks. Weaker commodity prices can reduce farm revenues even as production costs fall, making cash-flow management and sales strategy essential. Agribusiness firms and farmers are likely to focus on debt service, inventory management and possibly forward sales to stabilise income during periods of price weakness.
Monetary policy will be a key variable through 2026. Brazil’s policy rate remained at 15% per annum at the end of 2025. Market commentators expect that sustained disinflation across wholesale markets could permit gradual rate adjustments next year, provided economic activity and fiscal conditions remain stable. Any shift in interest rates will affect credit costs for producers and construction firms, and will be monitored closely by investors and policymakers.
Analysts attribute the IGP-M outcome to several factors: a global slowdown in demand, larger supplies of commodities and improved domestic harvests that reduced pressure on input prices. Because the IGP-M tracks price movements across the entire supply chain — from raw materials to consumer goods and construction — it tends to react faster than other inflation gauges to swings in commodity and exchange-rate dynamics.
For the agricultural sector, the index serves as a tactical indicator. Deflation in the IGP-M lowers the cost of production but does not guarantee higher real returns. Producers will need to balance the benefits of lower input costs against the prospect of weaker output prices and calibrate decisions on planting, investment and financing accordingly.
Overall, the 2025 IGP-M result offers some relief for producers and a potential opening for monetary normalisation next year, yet it leaves several sectors exposed to differing price trends. Policymakers and market participants will watch the evolution of commodity markets, domestic demand and fiscal policy to assess whether the disinflationary signals persist into 2026.
Key Takeaways:
- Brazil’s IGP-M closed 2025 with a 1.05% annual deflation, driven by a 3.35% fall in the producer price component (IPA).
- Lower wholesale costs eased input prices for agriculture and industry, but consumer inflation and construction costs rose during the year.
- Producers gain from cheaper fertilisers and seeds, yet weaker commodity prices may press farm revenues.
- Market expectations point to gradual monetary easing in 2026 if disinflation persists.
