Brazil Inflation Falls to 0.16% as Fuel Package Cushions War Shock

The first IPCA reading to partially capture the Iran war’s impact on energy costs arrived softer than feared — but the relief owes more to Lula’s R$30 billion fuel package than to any fundamental cooling in price pressures.

Brazil IPCA March 2026 came in at 0.16%, IBGE reported on April 10 — a sharp deceleration from February’s 0.83% and 0.67 percentage points below the prior month. The year-to-date accumulation stands at 1.42%, and the 12-month trailing rate sits at approximately 3.93%, remaining within the Banco Central’s 1.5%–4.5% target band around the 3% center. Six of the nine product groups tracked by IBGE showed price increases in March, but at a significantly slower pace than in February.

The transport category drove the headline surprise. The group reversed from a 0.72% increase in February to a 0.33% decline in March, according to IBGE analyst André Almeida, who cited airfares — which fell 9.14% after seasonal holiday-driven spikes — and gasoline, which decelerated from 2.93% in February to just 0.21% in March. Gasoline had been the single largest individual contributor to February’s IPCA, and its near-stalling in March reflects the government’s diesel and fuel relief package signed on March 12, which zeroed PIS and Cofins on diesel and created producer subsidies designed to cushion pump prices. Porto Alegre was the only metropolitan region to register an outright price decline in March, at −0.13%, while São Luís recorded the highest regional variation at 0.81%.

What the Number Means for Copom

The soft March print gives the Banco Central breathing room ahead of the April 28–29 Copom meeting, but it does not change the trajectory that the latest Focus survey already signaled. Market consensus has pushed the year-end 2026 IPCA forecast to 4.36% for four consecutive weeks, reflecting the expectation that war-driven energy costs will filter more visibly into April and May readings as Petrobras passes through additional refinery price adjustments. The Selic remains at 14.75% — the highest since July 2006 — and the Focus consensus sees it ending 2026 at 12.5%, implying roughly 225 basis points of further cuts across remaining meetings this year.

The complication is that the fuel package holding down March’s gasoline reading is itself under legal attack. A federal court suspended the 12% oil export tax that funds the R$30 billion (~$5.2 billion) subsidy framework, and the government has appealed. If the tax is struck down permanently, the fiscal math behind the diesel relief collapses — and the inflationary shield that produced March’s soft reading dissolves with it. The ceasefire’s fragility adds further uncertainty: if Brent climbs back above $100, the April IPCA could reverse everything the March number appeared to achieve.

The INPC — the index used for minimum wage adjustments, tracking families earning one to five minimum wages — came in at 0.19% in March, also sharply below February’s 0.81%. The year-to-date INPC accumulation is 1.58%, with the 12-month trailing rate at 3.40%.
