Brazil's Gross Public Debt Hits 81.9% of GDP, Highest Since 2021

Why Brazil's Gross Debt Rose to 81.9% of GDP in June

Brazil's gross general government debt rose to 81.9% of gross domestic product (GDP) in June, the highest level since April 2021, according to data released by the Banco Central do Brasil. The debt stock reached R$ 10.809 trillion, up from R$ 10.622 trillion in May, when the ratio stood at 81% of GDP.

The central bank attributed the monthly increase of 0.9 percentage points mainly to nominal interest accruals, which added 0.8 percentage point, and net debt issuance, which added 0.6 percentage point. These were partially offset by the effect of nominal GDP expansion, which reduced the ratio by 0.5 percentage point.

In the year to June, the gross debt ratio rose by 3.3 percentage points. Interest accruals contributed 4.9 percentage points and net debt issuance added 1.3 percentage points, while nominal GDP growth subtracted 2.7 percentage points and currency appreciation subtracted 0.2 percentage point. The Gross General Government Debt (DBGG) covers the federal government, the National Social Security Institute (INSS), and state and municipal governments.

Separately, the net debt of the non-financial public sector reached 68.5% of GDP in June, or R$ 9.034 trillion, up from 67.9% in May (R$ 8.898 trillion). The central bank said the monthly change reflected a 0.4 percentage point increase from the primary deficit and a 0.9 percentage point increase from nominal interest accruals.

The Interest Burden Behind the Return to 2021 Debt Levels

Banco Central's Numbers Put Debt Back to 2021 Levels

The June reading of 81.9% of GDP is the highest since April 2021, when the ratio stood at 82.6%. That comparison is more than historical trivia: it shows that the decline in Brazil's debt ratio recorded in the intervening years has been largely reversed, and the country is again operating near the peak of its recent debt cycle.

Interest Accruals Are the Main Engine

The central bank's breakdown is explicit: interest accruals contributed 0.8 percentage point in the month and 4.9 percentage points in the year to June. This is the cost of carrying a large debt stock at current nominal interest rates, and it is now the dominant driver of the ratio. Net issuance added a further 1.3 percentage points over the year, meaning the government is still borrowing to fund its operations rather than relying on primary surpluses to stabilize the debt.

Gross vs. Net Debt Shows Two Different Stories

Net public sector debt, at 68.5% of GDP, is much lower than gross debt because it subtracts public-sector assets such as international reserves. The gap between the two series highlights why analysts focus on the gross measure: it is the one most directly influenced by interest accruals and is the ratio most closely watched in assessments of sovereign creditworthiness. The June data show both measures moving in the same direction, upward.

What This Means for Fiscal Credibility

The combination of a persistent primary deficit and a rising interest burden leaves little room for the debt ratio to stabilize on its own. The offsets so far this year have come from nominal GDP growth and currency appreciation, contributions that are cyclical and cannot be relied upon indefinitely. Without a change in the primary balance, the gross debt ratio is likely to keep climbing in upcoming releases.

What the Debt Trajectory Means for Fiscal Watchers

• Track the Banco Central do Brasil's monthly fiscal statistics reports for the primary result: in June, the primary deficit added 0.4 percentage point to the net debt ratio, while interest accruals added 0.9 percentage point.
• For investors in Brazilian sovereign debt, the gross debt ratio at 81.9% of GDP, the highest since April 2021's 82.6%, puts renewed focus on whether interest costs, which contributed 4.9 percentage points to the ratio in the year to June, keep outpacing nominal GDP growth.
• Policymakers should note that the main offsets to debt accumulation this year, nominal GDP growth (-2.7 percentage points) and currency appreciation (-0.2 percentage point), are cyclical and may not persist at current strength.
