What is the brazilian real to dollar exchange rate?
Brazilian Real vs dollar and Dollar vs brazilian real are the same question: this page quotes the pair the way markets do (USD/BRL).
| When | Brazilian reais per US dollar | Date | Change in US dollar's value |
|---|---|---|---|
| Now | 5.0410 | Oct 23, 2026 | |
| 1 year ago | 5.4178 | Oct 17, 2025 | -7.0% |
| 3 years ago | 5.0346 | Oct 20, 2023 | +0.1% |

| Measure | High | Low | Volatility |
|---|---|---|---|
| Past year | 5.5384 Dec 26, 2025 | 4.8976 May 8, 2026 | 10.8% a year |
| Past five years | 6.2021 Dec 27, 2024 | 4.6944 Apr 1, 2022 | 12.2% a year |
"Volatility" is the annualised standard deviation of weekly moves: 10.8% means the rate typically swings about that much up or down over a year. Exchange rates are the Federal Reserve's daily noon-buying-rate series (the H.10 release) from FRED.
Who pays more to borrow: the Federal Reserve or Banco Central do Brasil?
A central bank's policy rate sets the price of short-term money in its currency; the 10-year bond yield is what governments pay to borrow for a decade.
- Dollar (Fed)
- Brazilian Real (Banco Central do Brasil)
| Central bank | Policy rate | As of | Last move |
|---|---|---|---|
| The Federal Reserve (USD) | 3.88% | October 20, 2026 | September 2026 (3.63% to 3.88%) |
| Banco Central do Brasil (BRL) | 13.75% | October 20, 2026 | September 2026 (14% to 13.75%) |
Banco Central do Brasil rate is 9.88 percentage points above the Federal Reserve's. The policy rate is the rate a central bank sets for overnight lending (the Fed: mid-point of the Federal Reserve target rate). There is no 10-year yield for Brazil here: the free source this site uses (OECD data on FRED) does not carry one.
What are real interest rates in the United States and Brazil?
A rate means little without inflation.
| Country | Policy rate | Inflation, year on year | Real rate |
|---|---|---|---|
| The United States | 3.88% | 3.40% August 2026 | 0.48% |
| Brazil | 13.75% | 4.22% August 2026 | 9.53% |
The real rate is the simple Fisher approximation: the policy rate minus the latest year-on-year consumer price inflation. A positive real rate means cash at the central bank's rate earns more than prices are rising; a negative one means it does not. Right now Brazil has the higher real rate (9.53% against 0.48%). Inflation is the BIS's consumer price series for each economy; the latest month differs by country (August 2026 for the United States, August 2026 for Brazil).
Is the Brazilian real strong, or just strong against the dollar?
A bilateral rate hides what a currency does against everything else.
- Dollar
- Brazilian Real
| Currency | Index now | Ten-year average | Versus its average | Ten-year range |
|---|---|---|---|---|
| Dollar | 107.1 | 102.2 | +4.8% | 91.7 to 114.5 |
| Brazilian Real | 117.2 | 117.5 | -0.2% | 90.3 to 151.3 |
This answers a different question from the exchange rate above. A currency can gain against one partner and fall against most others. The BIS's real effective exchange rate weighs a currency against its trading partners and adjusts for inflation differences, so a reading above 100 means it is more expensive than in 2020 and below 100 cheaper. In September 2026, the dollar was near its ten-year average and the Brazilian real was near its ten-year average. The "stronger" and "weaker" labels use this site's own cut-off of 5% either side of the average.
Do interest rate gaps move the brazilian real-dollar exchange rate?
The textbook says money flows to the higher rate. The last ten years of data say this about this pair:
Over the past ten years, the change in the policy-rate gap and the change in USD/BRL had a weak link (correlation 0.06, 39 three-month windows).
How this is measured: for each non-overlapping three-month window, the change in the gap between the two rates (Brazilian Real minus Dollar, in percentage points) against the percentage change in the price of one brazilian real in us dollars. A correlation of 0 means no link and 1 or -1 a perfect one; under 0.2 is weak and over 0.5 strong. A link is not a cause, and a weak link over ten years says little about the next three months. This is an observation, not a forecast.

Companies that earn or pay in more than one currency see their reported profits move with exchange rates, and a currency's strength affects imports, exports and the value of overseas investments. Use the screener to look at the companies themselves, and dollar vs euro for money supply and cash in circulation.
Where does this data come from, and how often is it updated?
Policy rates, inflation and the real effective exchange rate come from the Bank for International Settlements (BIS) Data Portal; exchange rates and 10-year yields come from FRED (the St. Louis Fed). The page is rebuilt every week.
Where does this data come from?
- Policy rates, inflation and strength: BIS Data Portal: central bank policy rates, consumer price inflation (year on year) and the real effective exchange rate index (broad basket, 2020 = 100).
- Exchange rates and 10-year yields: FRED (St. Louis Fed): the Federal Reserve's H.10 daily exchange rates and OECD 10-year government bond yields.
- Method and limits: every figure is shown as published, with its date, and refreshed weekly (data as of October 23, 2026). There is no composite score, and nothing here predicts where a rate goes next. Read the Editorial Standards for how this site handles data.
