Brazil Price Index Jumps 1.50% in September

Economy: Brazil

Brazil’s IGP-DI price index rose 1.50% in September, up from 0.06% in August, the Getulio Vargas Foundation (FGV) said on Wednesday 7 October 2026. The index feeds into rents and long-term contracts, and it lifted the 12-month rate to 3.80%.

What We Know

The IGP-DI rose 1.50% in September after 0.06% in August, FGV said. The index is up 3.72% so far in 2026 and 3.80% over 12 months.

FGV builds the index from producer prices (60% weight), consumer prices (30%) and construction costs (10%). Its economist Matheus Dias attributed the producer rise to soybeans, soybean meal and corn, plus a fuel price increase.

Producer prices rose 1.95% after 0.10% in August. Consumer prices rose 0.67% after falling 0.37% in August.

Household electricity rose after the discounts from the Itaipu bonus, a credit on power bills from the Itaipu dam, ended. Fresh food also weighed, mainly tomatoes and potatoes.

Construction costs slowed to 0.22% from 0.66% in August. Brazilian media reported that analysts had expected a rise of about 1.53%, so the result was close to forecasts.

How the IGP-DI Differs From Official Inflation

The IGP-M, a sister index from FGV, rose 1.57% in September and 3.34% over 12 months. Many rental contracts in Brazil use the IGP-M to set the yearly rent increase.

The official gauge is the IPCA, produced by the statistics agency IBGE, which tracks only what households pay. The IGP-DI gives producers the largest weight, so it moves more with crops and fuel.

Rates and the Central Bank

The central bank cut its Selic benchmark rate from 14.00% to 13.75% on 16 September. Its next meeting is on 3 and 4 November, with the decision announced after the second day.

IBGE publishes September’s IPCA on Friday 9 October at 9:00 Brasília time. Bank economists expect a monthly rise of roughly 0.7% to 0.8%, which would lift the 12-month rate to about 4.5%, according to Brazilian media.

What Prediction Markets Say

Polymarket traders put the chance of a 25-basis-point cut in November at 85.5%, with about US$44,600 traded on that market. Kalshi, a US exchange regulated by the CFTC, the US derivatives regulator, showed 88% for a cut of up to 25 basis points, on 5,689 contracts traded.

These prices are real-money bets, not polls or official guidance. They were read at 6:36 pm ET on 7 October and move with the news.

Why we show this: prediction markets turn real-money bets into a live probability that moves within minutes of the news, which is why investors, campaigns and newsrooms in the United States now follow them closely. We show them next to polls and official results, never instead of them.

What Is Not Known

It is not yet known how much of the producer jump will reach shop prices. The central bank has not said whether the September reading changes its plans.

The IGP-DI does not measure a household basket, so the IPCA on 9 October is the better test of what shoppers pay. Contracts tied to FGV indices follow FGV’s own published tables.

What It Means for US Readers and Investors

Brazil is Latin America’s largest economy, and rate cuts there affect the real and the returns on Brazilian bonds held by US funds. Soybean and corn prices, which drove the producer jump, also matter to US farmers who compete with Brazilian exports.

For expatriates renting in Brazil, many leases adjust by the IGP-M at their annual review, so the 3.34% twelve-month figure is the one to watch. Higher power bills after the Itaipu discount are a reminder that household costs can move quickly.

Many leases are adjusted by the sister index, the IGP-M, which rose 1.57% in September and 3.34% over 12 months. The IGP-DI is used in some other contracts.

Do prediction markets expect a rate cut?

Polymarket gives 85.5% to a 25-basis-point cut in November, and Kalshi gives 88% to a cut of up to 25 basis points. These are bets, not forecasts from the central bank.
