Brazil Public Debt Heads to 89.7% of GDP by 2030, Budget Papers Show

The number in the budget papers is 89.7 percent. The number the finance minister gave a news portal the same day was 80 percent.

Brazil public debt is on a worse path than the government forecast five months ago. The document saying so went to Congress on Friday. Supplementary information to next year’s budget bill puts gross debt at 89.7 percent of GDP in 2030. In April, the budget guidelines bill, which sets the framework for the next budget, put the peak at 87.8 percent.

What the Brazil public debt projection actually shows

The central scenario runs like this. Gross general government debt, owed by the federal, state and municipal governments, ends 2026 at 83.7 percent of GDP. It reaches 89.6 percent in 2029, peaks at 89.7 percent in 2030 and then turns down. The government’s own central case stays just below 90 percent.

The same papers model a lower-band case, in which the government keeps landing at the bottom of its tolerance range. That path crosses 90 percent in 2029 and peaks at 91.1 percent in 2031.

The fiscal risks annex sent with the bill on 31 August, reported by the Curitiba daily Gazeta do Povo, ran other scenarios. Its most positive case peaks at 88.4 percent in 2028; an extreme case reaches 117 percent by 2036.

The bigger change is the revision. In April the projected peak was 87.8 percent, and the Treasury’s June fiscal projections report said 87.9 percent. In September it is 89.7 percent, and the peak comes a year later, in 2030. That is nearly two points of deterioration in five months.

Two rulers, one country

Brazil’s debt is reported both at about 83 percent and near 100 percent of GDP, and both figures are correct. Brazil’s central bank counts only part of the Treasury bonds it holds. It includes those sold to the market under repurchase agreements, short-term deals to buy them back. The International Monetary Fund counts the whole portfolio.

The central bank’s own July data put the gap at about 13 points: 95.4 percent on the IMF concept against 82.6 percent. The Fund’s July 2026 Article IV review, its annual check of Brazil’s economy, projects 97.8 percent for 2026. It sees 104.8 percent by 2030.

Both use the same net debt figure, debt minus government financial assets, which stood at 69.1 percent of GDP in July.

The Fund and the finance ministry are not issuing rival forecasts of the same thing. They measure with different rulers. On the comparable measure Brazil is already close to 100 percent. The Fund still rates the risk of debt distress as moderate, citing cash buffers and very little foreign-currency debt.

The Senate’s own watchdog sees something much worse

The Independent Fiscal Institution, which reports to the Senate, uses the same central bank methodology as the government. Its numbers are therefore directly comparable, and they are far bleaker. Its June report has debt rising every year to 102 percent by 2032 and 115 percent by 2036. It sees no stabilisation within that horizon.

Its September report came out on 17 September, a day before the budget papers reached Congress. It puts 2027 debt at 86.4 percent of GDP. It also sees a primary deficit, the budget gap before interest payments, of R$86.1 billion (about US$16.8 billion) in 2027. The government projects a surplus of R$18.6 billion (about US$3.6 billion).

Dollar figures use 5.11 reais per US dollar, the central bank’s reference rate for 21 September 2026.

A key figure comes from its June report. The institution calculates that stabilising the debt ratio would require a primary surplus of 2.1 percent of GDP every year. The official targets are 0.25 percent for 2026 and 0.5 percent for 2027. The gap between what is needed and what is targeted is more than 1.5 points of GDP a year.

The minister and the annex do not agree

Friday 18 September was the day the budget papers went to Congress. That same day Finance Minister Dário Durigan told the news portal UOL that debt would be under 80 percent in 2030. At worst, he said, it would be 80 percent. His own ministry’s document says 89.7 percent, which is a gap of roughly ten points.

The reports of the interview do not say whether he meant gross or net debt. Net debt stood at 69.1 percent of GDP in July, and the IMF projects it at about 80 percent in 2030.

Durigan has been consistent on the diagnosis. In July he called debt stabilisation the last mile of the adjustment and said primary surpluses should arrive in 2028 and 2029. He attributed the recent rise mainly to high interest rates rather than to primary deficits. The watchdog’s September report argues the link also runs the other way, with the debt pushing up rates.

On 21 September, Planning Minister Bruno Moretti told the news site g1 that the 2026 budget had found extra room. Lower projected mandatory spending, mostly on pensions, freed R$19.6 billion (about US$3.8 billion), he said.

Part funds a 15.04 percent rise in Bolsa Família, the flagship cash-transfer programme for poor families, from 19 October. He put its cost at R$5.8 billion (about US$1.1 billion) this year and R$22.7 billion (about US$4.4 billion) in 2027.

Moretti said the rise has “zero” effect on the fiscal rules. He said its timing, weeks before the 4 October election, followed the arrival of final spending data.

Why this reaches your pocket

The mechanism was quantified a day before the budget papers landed. The fiscal body studied the term premium, the extra yield investors demand to hold long-dated government bonds. It found a statistically significant link with the debt level. The fiscal component rose from 2.10 points in 2011 to 2013 to 3.16 points in the twelve months to August 2026.

That is above the 2.41-point average during the fiscal crisis of 2014 to 2016. It concentrates at five and ten years, which means investors are pricing the trajectory rather than this year’s budget.

Two further numbers explain why it compounds. In the twelve months to July, interest and net new borrowing added 10.5 points of GDP to the debt ratio. Nominal growth subtracted only 5.2. By the fiscal body’s count, more federal debt is now tied to the Selic rate, Brazil’s benchmark interest rate. That share rose from 35.7 percent at the end of 2023 to 46.4 percent in July. Almost half the debt now changes cost whenever the central bank moves rates.

For a reader holding reais, the currency has had a good year. It is up about 7.6 percent against the dollar, helped by high interest rates. The central bank cut its Selic rate to 13.75 percent on 16 September. For a reader holding Brazilian bonds, the fiscal body puts the debt’s share of the term premium at roughly 3.16 points.
