Brazil's official inflation preview accelerated in May and came in above financial market projections. The IPCA-15 advanced 0.62% in the month, against expectations of 0.53% to 0.57% according to different surveys, and accumulates a 4.64% rise over 12 months — above the 4.5% inflation target ceiling.

"O IPCA-15 de maio (0,62%) ficou acima da mediana das projeções do mercado financeiro, que era de 0,57%, segundo a Bloomberg. O intervalo das estimativas coletadas pela agência ia de 0,47% a 0,65%."

The upside surprise was mainly driven by food and beverages, which rose 1.38% and contributed 0.30 percentage points to the result. Residential electricity had a 2.16% increase, reflecting the introduction of the yellow tariff flag, while medications and personal hygiene products also pressured the index. In contrast, fuels declined, with gasoline falling 1.32%.

"Entre os nove grupos pesquisados, alimentação e bebidas teve a maior variação, com alta de 1,38% e impacto de 0,30 ponto percentual no resultado geral."

The result generated immediate reaction in financial markets. In Monday's trading session, the dollar rose 0.66% to R$ 5.061, while the Ibovespa fell 0.48% to 175,744 points. Investors' perception is that the Central Bank may keep interest rates high for longer given inflationary pressure.

"A moeda estadunidense encerrou esta quarta-feira (27) vendida a R$ 5,061, com alta de R$ 0,033 (+0,66%)... O Ibovespa, principal índice da bolsa brasileira, recuou 0,48%, aos 175.744 pontos... O resultado reforçou a percepção de que o Banco Central poderá manter juros elevados por mais tempo ou reduzir a Selic de forma mais lenta."

Year-to-date, the IPCA-15 accumulates a 3.02% rise. Among the metropolitan regions surveyed, Goiânia had the highest monthly variation (1.41%), driven by fuels, while Brasília recorded the lowest result (0.33%).
