Brazil's inflation story of 2022–26 is, in many ways, the clearest recent example of how effective aggressive monetary policy can be when delivered by a credible, independent central bank. Starting from a peak of 12.1% in April 2022 — driven by a combination of post-pandemic demand-pull, global commodity shocks, and real (BRL) depreciation — the Banco Central do Brasil (BCB) executed one of the most forceful tightening cycles in emerging market history.

The tightening cycle

The BCB raised the Selic rate from 2.0% (March 2021) to 13.75% (August 2022) in just 18 months — 1,175 basis points of hikes. Crucially, it then held rates at 13.75% for 12 months, resisting political pressure to cut prematurely. Long-run inflation expectations (as measured by the Focus survey of professional economists) never rose above 7% during the entire episode — a sign that market participants believed the BCB would ultimately win. This credibility made the eventual disinflation faster and less economically costly than in countries where expectations became more unanchored. The sacrifice ratio — the output cost of reducing inflation by one percentage point — was relatively low by historical standards, partly because of this anchoring effect.

What drove the decline

Three forces worked together to bring Brazilian CPI from 12% to under 5%: (1) monetary tightening cooling domestic demand, particularly credit-driven spending; (2) global commodity price normalisation — food and energy, which were significant drivers of the 2022 peak, both fell back globally from mid-2022 onward; (3) BRL appreciation as high Selic rates attracted capital inflows, reducing imported inflation. These factors compounded, producing rapid disinflation once the monetary transmission mechanism had time to work (typically 12–18 months after rate hikes).

What remains sticky

Despite the dramatic headline decline, two components remain above target. Services inflation at 5.3% reflects Brazil's tight labour market — urban unemployment fell to 6.8% in late 2026, supporting wage demands. Food-at-home inflation at 5.1% is partially driven by continued global grain price volatility, amplified by Brazil's high food import exposure in some categories. The BCB has begun its cutting cycle (Selic at 11.25%), but has signalled caution about cutting too quickly while services inflation remains sticky.
