The 10-year Brazilian government bond yield has risen above 13.6% after an earlier slide to two-month lows of 13.55% on September 17th, as investors assessed the latest Brazilian central bank’s decision and forward guidance while US Treasury yields lifted global long rate benchmarks. The BCB held its benchmark interest rate at 15% and signalled a prolonged hold because inflation remains elevated near 5.1% even though activity has softened, with the IBC-Br index down 0.5% in July and unemployment around 5.6% in the July moving quarter. That tight labour market limits pressure on Copom to cut quickly. Meanwhile, US 10-year yields climbed as markets digested the Federal Reserve decision and updated forecasts. The Fed cut the funds rate by 25 basis points and signalled further easing later this year, yet its upward revisions to growth and inflation reduced the odds of a rapid easing cycle and helped push US long yields higher.
