Key economic indicators
IGP-M and other Brazilian price indices
3 min
The IPCA is the headline, but Brazil has several other price indices, and knowing what each measures stops you from confusing them.
IGP-M — the "rent index"
The IGP-M (Índice Geral de Preços do Mercado), calculated by the Fundação Getulio Vargas (FGV), is famous for being the benchmark used to adjust rental contracts and some regulated tariffs. It differs from the IPCA in important ways:
- It gives heavy weight to wholesale prices (the IPA component), so it is strongly influenced by the exchange rate and commodity prices.
- Because of that, the IGP-M can swing far more violently than the IPCA — it spiked dramatically when the real weakened sharply, even as consumer inflation stayed calmer.
The family of FGV indices
- IPA — wholesale producer prices (the largest part of the IGP).
- IPC — consumer prices.
- INCC — construction-cost index.
- The IGP-M, IGP-DI and IGP-10 are the same basket measured over different collection windows.
Why an investor cares
- Real-estate and rental assets, including many real-estate funds (FIIs), have income tied to the IGP-M, so its swings affect those cash flows directly.
- The gap between IGP-M and IPCA is a useful tell: when wholesale prices (IGP-M) run hot while consumer prices (IPCA) lag, it often signals currency-driven cost pressure working its way through the supply chain — a possible warning of consumer inflation to come.
You do not need to track every index, but you should never mistake a scary IGP-M headline for the inflation number that actually drives the SELIC. That is the IPCA.
