Fed rate gap at 9.75 points keeps global carry trade in focus
Brazil's central bank holds its Selic rate at 13.75% following Lula's reelection, maintaining a wide yield gap with the Federal Reserve.
The interest rate on a standard U.S. Treasury bill or money market fund now hovers at 4.0% following the Federal Reserve's decision on October 28, 2026, to maintain its benchmark target range at 3.75% to 4.00%. For retail investors holding cash in the United States, this yield represents a stable, low-risk benchmark. Yet, across global markets, a massive yield disparity is quietly redirecting the flow of institutional capital.
The Central Bank of Brazil's monetary policy committee, known as Copom, voted to hold its benchmark Selic rate steady at 13.75%. This decision paused a cycle of rate cuts that had been underway since March. With the Federal Reserve's upper target rate sitting at 4.0%, the yield gap between the two nations stands at exactly 9.75 percentage points.
This 9.75-point spread is the engine behind the "carry trade," a financial strategy where global investors borrow dollars at low U.S. rates to buy high-yielding Brazilian government bonds. This mechanism heavily influences the exchange rate managed by the Central Bank of Brazil. When the yield gap is wide, capital tends to flow into Brazil, strengthening the local currency. Conversely, if the Federal Reserve raises rates or Brazil cuts its own too aggressively, the gap narrows, prompting investors to pull their money out and causing the real to depreciate against the dollar.
The decision by Brazilian central bank president Gabriel Galípolo and his committee to halt rate cuts reflects growing domestic caution. Policymakers are facing heightened inflation expectations following the October 25, 2026, reelection of President Luiz Inácio Lula da Silva, which triggered a sharp depreciation of the real. By keeping the Selic rate at 13.75%, the central bank aims to anchor consumer prices and defend the currency, even as local businesses complain about the high cost of credit. For global investors, this means the lucrative yield premium is locked in for the near term, though it comes with elevated political and fiscal risks.

Dollar-denominated exchange-traded funds are directly affected by these macroeconomic shifts. The iShares MSCI Brazil ETF, listed in New York, tracks large and mid-sized Brazilian equities. Because the fund is priced in U.S. dollars, its performance is highly sensitive to fluctuations in the Brazilian real, which is influenced by the 9.75-point interest rate gap and the resulting carry trade flows.
