The primary deficit has improved from its recent trough but remains wider than a year ago
Recent dynamics
Brazil's twelve-month primary fiscal balance remained close to balance during the second half of 2025, but gradually deteriorated as the year progressed. The deficit widened from 0.19% of GDP in August to 0.43% by December.
The deterioration became more pronounced during the first half of 2026. The twelve-month deficit reached 1.06% of GDP in March, improved modestly in April, and then widened again to 1.14% in May and 1.19% in June, the weakest reading in the period shown.
The latest data show a meaningful improvement from that mid-year trough. The deficit narrowed to 0.67% of GDP in July and 0.62% in August. Even so, the balance remains 0.43 percentage points weaker than in August 2025, when the twelve-month deficit was only 0.19% of GDP.
Interpretation and economic signal
The primary fiscal balance measures the public sector's revenues minus non-interest expenditures. It therefore isolates the underlying fiscal position before nominal interest payments on public debt are taken into account.
This EconoAtlas presentation reverses the sign of the original SGS 5793 series. The Central Bank publishes the indicator under the Public Sector Borrowing Requirements convention, where positive values represent deficits and negative values represent surpluses. Here, the sign is inverted so that positive values represent primary surpluses and negative values represent primary deficits.
The twelve-month ratio is more informative than an isolated monthly fiscal result because it smooths seasonal revenue and expenditure patterns. A more negative balance means that non-interest expenditures are exceeding revenues by a larger amount relative to GDP, while movement toward zero indicates an improving underlying fiscal position.
The recent narrowing is therefore a constructive development at the margin. However, the balance remains weaker than a year earlier, so the improvement since June should not yet be interpreted as a full reversal of the fiscal deterioration accumulated over the previous twelve months.
Fiscal implications
The primary balance is a central determinant of debt dynamics because persistent deficits require additional financing before interest costs are considered. When borrowing costs are high, a primary deficit can combine with large interest expenses to place additional upward pressure on public debt ratios.
Conversely, sustained primary improvement reduces the amount of new borrowing needed to finance government operations and can help stabilize debt over time. The scale of the adjustment required depends on nominal GDP growth, the effective interest rate on public debt, and the starting level of indebtedness.
Conclusion
Brazil's primary fiscal balance has improved noticeably from the weak readings recorded in the middle of 2026, but the twelve-month result remains in deficit and materially worse than one year earlier.
The current signal is therefore mixed: recent momentum is favorable, while the broader year-over-year comparison still points to fiscal deterioration. A sustained move closer to balance — and eventually into surplus — would provide stronger evidence that the underlying fiscal position is improving enough to support debt stabilization.
