Brazil’s Finance Ministry survey of forecasters now sees a 2026 federal deficit of 53.05 billion reais (about US$10.5 billion) before interest. The Brazil deficit forecast for 2027 falls, but debt is still expected to reach 87.0% of GDP.
The Brazil deficit forecast for 2026 rose to 53.05 billion reais (about US$10.5 billion) in the Finance Ministry’s October survey. The survey matters to US investors in Brazilian assets, because it tracks the debt path before the 25 October runoff.
The ministry published the report on Thursday, 15 October, at 10:00 Brasília time (9:00 a.m. ET). The 2026 figure is 0.78 billion reais (about US$154 million) above September’s 52.27 billion reais (US$10.4 billion), a rise of 1.5%.
For 2027, forecasters cut their deficit estimate to 44.0 billion reais (US$8.7 billion) from 45.35 billion reais (US$9.0 billion). Gross debt is still expected to rise from 83.4% of GDP in 2026 to 87.0% in 2027.
What the Brazil Deficit Forecast Shows
The survey’s headline number is the primary result, which is the federal budget balance before interest payments. On the survey’s own medians, the 2026 gap equals about 0.4% of GDP, forecast at 13.65 trillion reais (US$2.7 trillion).
The 2027 gap of 44.0 billion reais (US$8.7 billion) is about 0.3% of a 14.53 trillion reais (US$2.9 trillion) economy. Both percentages are calculated from the survey’s medians and are not published figures.
The Finance Ministry’s Secretariat of Economic Policy collects the forecasts from financial institutions and consultancies each month. Answers were gathered through the fifth business day of October, well before the 25 October runoff.
Poder360 reported the same figures on Thursday, citing the ministry. Dollar figures here use 5.04 reais per US$ (open.er-api.com, 15 October), and rounded values may differ slightly.

How Forecasts Have Moved Since August
In August’s survey the 2026 deficit forecast stood at 59.1 billion reais (about US$11.7 billion), the highest of the three latest editions. By October it had fallen 6.1 billion reais (about US$1.2 billion) to 53.05 billion reais.
The 2027 estimate fell further, from 55.0 billion reais (US$10.9 billion) in August to 44.0 billion reais (US$8.7 billion) in October. That is a cut of 11.0 billion reais, or about US$2.2 billion.
Gross general government debt, Brazil’s main public debt measure, is forecast at 83.4% of GDP at the end of 2026. It covers federal, state and city governments, and is up from 83.2% in September and 83.0% in August.
For 2027 the debt forecast is 87.0%, unchanged from September and up from 86.77% in August. The gap between the two years is 3.6 percentage points.
Debt, Revenue and the Interest Bill
Forecasters see federal revenue collection of 3.21 trillion reais (about US$637 billion) in 2026, up 7.9 billion reais (US$1.6 billion) from September. Net revenue is 2.58 trillion reais (US$512 billion), down 1.3 billion reais (US$0.3 billion), after transfers to states and cities.
Total federal spending is forecast at 2.625 trillion reais (US$521 billion), unchanged from September. For 2027 the survey sees spending at 2.793 trillion reais (US$554 billion).
The nominal deficit, which includes interest, is forecast at 1.12 trillion reais (US$222 billion) for 2026. For 2027 it is 1.13 trillion reais (US$225 billion), and both figures rose since September.
Subtracting the primary median from the nominal one leaves about 1.07 trillion reais (US$212 billion), roughly 7.8% of GDP. That is a rough implied interest cost, calculated from two medians and not a survey result.
The implied interest cost is about 20 times the primary gap of 53.05 billion reais (US$10.5 billion). Interest costs, not the primary gap, make up most of the nominal deficit on these medians.
What It Means for US Readers
US investors in the real, or in New York-listed oil producer Petrobras and miner Vale, are exposed to Brazil’s debt path. The survey shows a primary deficit little changed since September, but forecasters still expect debt to climb to 87.0% in 2027.
Because the implied interest bill is about US$212 billion, interest rates weigh more on Brazil’s budget than the primary gap does. Who owns Brazilian assets is set out in Foreign Powers and Investors in Brazil.
Brazilian shares trade on B3 in São Paulo, the country’s financial centre, and the city guide gathers more coverage from there. The survey is a forecast poll, not a policy decision.
The central bank’s latest official debt figures, for August, are covered in a separate report. Forecasts and official data can differ, and Who Runs Brazil’s Economy in 2026 profiles the Finance Ministry behind the survey.
What Is Not Known
The October report does not state how many institutions answered, so the medians cannot be read as a firm consensus. A median is the middle forecast, and individual banks may expect a larger or smaller gap.
The survey does not say why forecasts for 2026 and 2027 fell after August, and the cause was not established. It also does not compare the deficit with the government’s own 2026 target, and this article draws no such comparison.
Forecasters’ answers were gathered before the runoff, so the survey cannot show how the result will move their numbers. The November edition is the first that can.
What Comes Next
Brazil holds its presidential runoff on Sunday, 25 October. President Lula of the Workers’ Party faces Senator Flávio Bolsonaro of the conservative Liberal Party.
The next Prisma Fiscal is due in November, and its answers will be collected after the runoff. The exact release date is not confirmed.
