Brazilian Rates Tick Up as Oil Swings and Inflation Surprise Roil Markets
Conflicting US‑Iran reports that cut oil left Brazil's market sensitive to dollar moves, raising pressure from an above‑forecast May IPCA‑15 on monetary easing.
Overview
- A May 27 report by Iranian state TV that sketched a preliminary US‑Iran deal to reopen the Strait of Hormuz sent Brent down sharply before the White House disputed the account and President Trump said talks were continuing.
- Brazil's IPCA‑15 for May surprised to the upside at 0.62% monthly and 4.64% year‑on‑year, a reading that increases market concern that the central bank will slow or pause planned Selic cuts.
- DI futures ended May 27 marginally higher across maturities, with the Jan‑2027 contract near 14.065% and long‑dated contracts also inching up as traders re‑priced monetary easing odds.
- The real weakened and equities fell as the dollar closed around R$5.061 and the Ibovespa dropped about 0.48%, with Petrobras shares hit by the oil selloff despite the intraday commodity swing.
- Markets said the decline in oil did not translate into lower local rates because a stronger dollar, only small moves in US Treasury yields and lingering geopolitical doubt kept investors cautious, raising second‑order risks for borrowing costs and consumer prices.
