Brazil's central bank governor, Gabriel Galipolo, told lawmakers on Tuesday that the large proportion of sovereign debt tied to the benchmark Selic interest rate undermines the transmission of monetary policy. Speaking at a Senate hearing, he said that when policy rates rise those holding floating-rate government bonds see their disposable income increase, a dynamic that runs counter to efforts to slow demand.
"The more I raise interest rates, the more income holders (of floating-rate) bonds receive," Galipolo said in his remarks, noting that roughly half of the government's outstanding debt is linked to the Selic. That share, he said, is a distinctive feature of Brazil's public debt structure and traces back to the creation of securities known as LFTs, which were designed to facilitate the government's ability to roll over liabilities.
The Selic rate currently stands at 14.50% as the central bank works to bring annual inflation, which measured 4.39% in April, down toward the official 3% target. Galipolo highlighted that core inflation gauges are running at similar levels to headline inflation, leaving both measures above the target.
Galipolo also cautioned about broader risks facing monetary stabilization. He said discussions in the Senate about imposing a cap on the growth of public debt could backfire if market participants interpret such a constraint as making debt rollover impractical. That perception, he warned, could spur sharp risk aversion among investors, encouraging capital flight into other currencies and producing inflationary consequences.
Compounding the challenge, Galipolo pointed to two looming supply shocks at a time when inflation is already elevated and labor markets are exceptionally tight. He listed higher oil prices and the possibility of a very strong El Nino as specific supply-side risks. The governor noted that unemployment is at a record low and that incomes have been growing robustly, conditions that heighten the complexity of steering inflation back to target.
In sum, Galipolo presented a picture in which Brazil's debt composition, current inflation readings, strengthening labor market and potential external shocks together narrow the room for traditional monetary tightening to operate as intended.
